Super Blood Red Flower Moon

It will be blood red from all of Earth's sunrises and sunsets reflected on to the Moon's surface.

In the year's only full lunar eclipse, Earth will come between the Sun and the Moon.

What it will take to colonize the #Moon and #Mars @NASA



What it will take for humans to colonize the Moon and Mars

NASA's Artemis program will mark a significant milestone in US space flight history when it lifts off in late 2024. Not only will it be the first time that American astronauts have travelled further than LEO since the 1970s, and not only will it be the first opportunity for a female astronaut to step foot on the moon. The Artemis mission will perform the crucial groundwork needed for humanity to further explore and potentially colonize our nearest celestial neighbor as well as eventually serve as a jumping-off point in our quest to reach Mars. Given how inhospitable space is to human physiology and psychology, however, NASA and its partners will face a significant challenge in keeping their lunar colonists alive and well.

Back in the Apollo mission era, the notion of constructing even a semi-permanent presence on the surface of the moon was laughable — largely because the numerous lunar regolith samples collected and returned to Earth during that period were "found to be dry as a bone," Rob Mueller, Senior Technologist in Advanced Projects Development at NASA said during a SXSW 2021 panel. "That was the common wisdom, there is no water on the moon, and so for many years that was the assumption held in the [aerospace] community."

It wasn't until the late '90s that a neutron spectrometer aboard NASA's Lunar Prospector mission found telltale evidence of hydrogen atoms located at the moon's poles, suggesting the potential presence of water ice. And it wasn't until last October that the SOPHIA mission detected water on the sunlit surface of the moon, rather than only squirrelled away in deep, dark lunar craters.

"We had indications that H2O – the familiar water we know – might be present on the sunlit side of the Moon," Paul Hertz, director of the Astrophysics Division in the Science Mission Directorate at NASA Headquarters, said at the time. "Now we know it is there. This discovery challenges our understanding of the lunar surface and raises intriguing questions about resources relevant for deep space exploration."

Based on this new evidence, Mueller estimates that there should be enough water ice available to "launch a vehicle like the space shuttle every day for 2,000 years. So there's a lot of water on the moon. The trick is, is we have to find it, access it, and mine it, and then economically use it."

SpaceX smashes record with launch of 143 small satellites – Spaceflight Now

SpaceX launched a Falcon 9 rocket Sunday from Cape Canaveral with 143 small satellites, a record number of spacecraft on a single mission, giving a boost to startup space companies and stressing the U.S. military’s tracking network charged with sorting out the locations of all objects in orbit.

The 143 small spacecraft, part of SpaceX’s “Transporter-1” rideshare mission, took off from pad 40 at Cape Canaveral Space Force Station at 10 a.m. EST (1500 GMT), a day after thick cloud cover prevented the rocket from leaving Earth.

The 229-foot-tall (70-meter) Falcon 9 rocket soared toward the southeast from the launch pad at Cape Canaveral, then vectored its thrust to fly on a coast-hugging trajectory toward South Florida, before flying over Cuba, the Caribbean Sea, and Central America.

The unusual trajectory was similar to the track followed by a Falcon 9 launch in August 2020, which was the first launch since the 1960s from Florida’s Space Coast to head into a polar orbit.

The Falcon 9’s reusable first stage booster — flying for the fifth time — landed on SpaceX’s “Of Course I Still Love You” drone ship in the Atlantic Ocean southeast of Miami nearly 10 minutes after liftoff. SpaceX said it also retrieved the rocket’s payload fairing halves after they parachuted back to Earth in the Atlantic.

The rocket’s second stage powered into orbit with its 143 satellite passengers, flew over Antarctica, then briefly reignited its engine while heading north over the Indian Ocean.

The launch Sunday carried payloads for Planet, Swarm Technologies, Kepler Communications, Spire, Capella Space, ICEYE, NASA, and a host of other customers from 11 countries. The payloads ranged in size from CubeSats to microsatellites weighing several hundred pounds.

The Falcon 9 rocket will also delivered 10 more of SpaceX’s Starlink internet satellites into space, the first Starlink craft to head for a polar orbit.

Restoring #Apollo11’s Lunar Module Guidance Computer


Restorers Try to Get Lunar Module Guidance Computer Up and Running 


In 1976 in a warehouse in Texas, Jimmie Loocke bought two tons of scrapped NASA equipment. Years later he realized it included a computer from an Apollo lunar module, like the one used to guide the lander to the surface of the moon during Apollo 11. Fifty years after that mission, computer restoration experts in Silicon Valley are trying to get his computer working again. https://on.wsj.com/2Seg3v2

The biological exploration of space is just beginning. #Cassini Seeks Insights to Life in Plumes of Enceladus, Saturn’s Icy Moon - The New York Times


Cassini Seeks Insights to Life in Plumes of Enceladus, Saturn’s Icy Moon


After 11 years orbiting Saturn, NASA’s Cassini spacecraft has changed our understanding of liquid water in the outer solar system.
By JASON DRAKEFORD, DENNIS OVERBYE and JONATHAN CORUM on October 28, 2015. Photo by NASA. Watch in Times Video »
Where there is water, is there life?
That’s the $64 billion question now facing NASA and the rest of lonely humanity. When the New Horizons spacecraft, cameras clickingsped past Pluto in July, it represented an inflection point in the conquest of the solar system. Half a century after the first planetary probe sailed past Venus, all the planets and would-be planets we have known and loved, and all the marvelous rocks and snowballs circling them, have been detected and inspected, reconnoitered.
That part of human history, the astrophysical exploration of the solar system, is over. The next part, the biological exploration of space, is just beginning. We have finished counting the rocks in the neighborhood. It is time to find out if anything is living on them, a job that could easily take another half century.


NASA’s mantra for finding alien life has long been to “follow the water,” the one ingredient essential to our own biochemistry. On Wednesday, NASA sampled the most available water out there, as the Cassini spacecraft plunged through an icy spray erupting from the little Saturnian moon Enceladus.
Enceladus is only 300 miles across and whiter than a Bing Crosby Christmas, reflecting virtually all the sunlight that hits it, which should make it colder and deader than Scrooge’s heart.
But in 2005, shortly after starting an 11-year sojourn at Saturn, Cassini recorded jets of water squirting from cracks known as tiger stripes near the south pole of Enceladus — evidence, scientists say, of an underground ocean kept warm and liquid by tidal flexing of the little moon as it is stretched and squeezed by Saturn.
And with that, Enceladus leapfrogged to the top of astrobiologists’ list of promising places to look for life. If there is life in its ocean, alien microbes could be riding those geysers out into space where a passing spacecraft could grab them. No need to drill through miles of ice or dig up rocks.
As Chris McKay, an astrobiologist at NASA’s Ames Research Center, said, it’s as if nature had hung up a sign at Enceladus saying “Free Samples.”
Discovering life was not on the agenda when Cassini was designed and launched two decades ago. Its instruments can’t capture microbes or detect life, but in a couple of dozen passes through the plumes of Enceladus, it has detected various molecules associated with life: water vapor, carbon dioxide, methane, molecular nitrogen, propaneacetyleneformaldehyde and traces of ammonia.
Wednesday’s dive was the deepest Cassini will make through the plumes, only 30 miles above the icy surface. Scientists are especially interested in measuring the amount of hydrogen gas in the plume, which would tell them how much energy and heat are being generated by chemical reactions in hydrothermal vents at the bottom of the moon’s ocean.
It is in such ocean vents that some of the most primordial-looking life-forms have been found on our own planet. What the Cassini scientists find out could help set the stage for a return mission with a spacecraft designed to detect or even bring back samples of life.
These are optimistic, almost sci-fi times. The fact that life was present on Earth as early as 4.1 billion years ago — pretty much as soon as asteroids and leftover planet junk stopped bombarding the new Earth and let it cool down — has led astrobiologists to conclude that, given the right conditions, life will take hold quickly. Not just in our solar system, but in some of the thousands of planetary systems that Kepler and other missions squinting at distant stars have uncovered.
And if water is indeed the key, the solar system has had several chances to get lucky. Besides Enceladus, there is an ocean underneath the ice of Jupiter’s moon Europa, and the Hubble Space Telescope has hinted that it too is venting into space. NASA has begun planning for a mission next decade to fly by it.
And of course there’s Mars, with its dead oceans and intriguing streaks of damp sand, springboard of a thousand sci-fi invasions of Earth, but in recent decades the target of robot invasions going the other direction.
Some scientists even make the case that genesis happened not on Earth but on Mars. Our biochemical ancestors would then have made the passage on an asteroid, making us all Martians and perhaps explaining our curious attraction to the Red Planet.

NASA’s Next Horizon in Space 

Since New Horizons beamed back photos of Pluto, the question has loomed: What’s next? More than 1,600 Times readers shared their ideas. 

And then there is Titan, Saturn’s largest moon, the only moon in the solar system with a thick atmosphere and lakes on its surface, except that in this case the liquid in them is methane and the beaches and valleys are made of hydrocarbon slush.
NASA’s working definition of life, coined by a group of biologists in 1992, is “a self-sustaining chemical system capable of Darwinian evolution.”
Any liquid could serve as the medium of this thing, process, whatever it is. Life on Titan would expand our notions of what is biochemically possible out there in the rest of the universe.
Our history of exploration suggests that surprise is the nature of the game. That was the lesson of the Voyager missions: Every world or moon encountered on that twin-spacecraft odyssey was different, an example of the laws of physics sculpted by time and circumstance into unique and weird forms.
And so far that is the lesson of the new astronomy of exoplanets — thousands of planetary systems, but not a single one that looks like our own.
The detection of a single piece of pond slime, one alien microbe, on some other world would rank as one of the greatest discoveries in the history of science. Why should we expect it to look anything like what we already know?
That microbe won’t come any cheaper than the Higgs boson, the keystone of modern particle physics, which cost more than $10 billion to hunt down over half a century.
Finding that microbe will involve launching big, complicated chunks of hardware to various corners of the solar system, and that means work for engineers, scientists, accountants, welders, machinists, electricians, programmers and practitioners of other crafts yet to be invented — astro-robot-paleontologists, say.
However many billions of dollars it takes to knock on doors and find out if anybody is at home, it will all be spent here on Earth, on people and things we all say we want: innovation, education, science, technology.
We’ve seen this have a happy ending before. It was the kids of the aerospace industry and the military-industrial complex, especially in California, who gave us Silicon Valley and general relativity in our pockets.
In this era, a happy ending could include the news that we are not alone, that the cosmos is more diverse, again, than we had imagined.
Or not.
In another 50 years the silence from out there could be deafening.
Correction: October 28, 2015 
An earlier version of this article misstated part of the name of the institution where Chris McKay is an astrobiologist. It is NASA’s Ames Research Center, not Laboratory.

Look up at the sky - Richard Branson on the picture taken by #Cassini of the #Earth and #Moon

Image by Cassini
the picture taken by #Cassini of the #Earth and #Moon

Look up at the sky

Did you look up at the sky when all of us on Planet Earth had our photo taken from a billion miles away last week? Judging from the response online, it seems lots of you did.

Now Cassini have released the first images of Earth and its moon as tiny dots - Earth is the blue dot on the left; the moon is fainter on the right hand side.

Linda Spilker, Cassini project scientist, said: "Cassini's picture reminds us how tiny our home planet is in the vastness of space, but also testifies to the ingenuity of the citizens of this tiny planet to be able to send a robotic spacecraft so far away from home to take a picture of Earth and study a distant world like Saturn."

After urging people to go outside and stare at the sky while the photo was being taken, I particularly liked Martijn Scheffers reply on Facebook. "So I walked out, looked up, started smiling. After 2 seconds random bypassers declared me crazy. Why would a man gaze into the sky they said..."

I'm glad you looked up anyway Martijn. The better question is: why wouldn't you gaze up at the stars?

Voyager Spacecraft Reaches 'Last Leg' of Solar System - US News and World Report


Voyager Spacecraft Reaches 'Last Leg' of Solar System

This is a handout photo from the Jet Propulsion Lab showing the Voyager spacecraft. On right side of the craft is girder-like boom which holds science project equipment and imaging camera.       This photo from the Jet Propulsion Lab shows Voyager. On right side of the craft is girder-like boom which holds science project equipment and an imaging camera.
NASA announced Monday that Voyager 1, the spacecraft launched in 1977 with the goal of exploring the outer reaches of the solar system, has entered a new region at the "far reaches" of the solar system, and that the region is likely the last before it enters interstellar space.
Scientists at NASA's Jet Propulsion Laboratory said they expect the satellite to completely exit the heliosphere — the bubble of energy created by the sun and the physical end of the solar system — sometime in the next couple years.
"This region was not anticipated, it was not predicted, we can't predict exactly when we'll [leave it]," Edward Stone, Voyager project scientist, said in a conference call Monday.
NASA says that Voyager has now reached a "magnetic highway" in which charged particles from the sun leave the solar system and particles from outside the solar system to make their way in.
"Although Voyager 1 still is inside the sun's environment, we can now taste what it's like on the outside because the particles are zipping in and out on this magnetic highway," Stone said. "We believe this is last leg of our journey to interstellar space. Our best guess is it's likely just a few months to a couple years away."
Stone says that during its 35 year mission, the Voyager team has come to expect the unexpected. When it finally leaves the solar system, the team isn't sure what it'll find.
"Whatever we think we'll find, I'm sure we'll find something different," he said.
So far, Voyager 1 has traveled about 100 times the distance of the Earth to the Sun, or about 9.3 billion miles. The team estimates that they'll be able to continue communicating with Voyager until about 2025.

#Israeli Success in Downing #Hamas #Rockets Has World’s Attention - NYTimes.com


#IronDome in many countries' sights


Israel’s Antimissile System Attracts Potential Buyers

WASHINGTON — The success cited by Israel for its Iron Dome antimissile system in its confrontation with Hamas has re-energized American missile defense advocates and generated new interest in the global arms bazaar from nations like South Korea that face short-range rocket threats from hostile neighbors.
But even ardent supporters of a continent-size missile shield to guard the United States and other NATO members acknowledge the limitations of Iron Dome, which is a tactical system designed to shoot down unsophisticated rockets — basically flying pipe bombs — with a range of less than 50 miles.
Some American technical experts also say they want hard evidence before judging whether Iron Dome knocked out as many rockets as Israel has claimed. Iron Dome’s most salient feature, according to American experts now examining after-action reports from Gaza, may well be its software: The system rapidly discriminates between incoming rockets that are hurtling toward a populated area and others not worth expending a far costlier Iron Dome interceptor to knock down.
The conflict between Israel and Hamas focused global attention on missile defenses, and came as the United States and its Arab allies have undertaken a costly effort to knit together a regional shield in the Persian Gulf to protect cities, oil refineries, pipelines and military bases from a potential Iranian attack.
“This will ratify the common-sense notion that these systems can play a role in defending you,” said Eric S. Edelman, a former under secretary of defense for policy in the George W. Bush administration. “It will be especially relevant as we move into an era in which there will be more countries with small inventories of rockets and missiles — and more countries that will want to defend against them in a reasonable way.”
The effort in the gulf is envisioned to include advanced radar as well as sets of two antimissile systems with accompanying radar: Patriot Advanced Capability interceptors and the Terminal High Altitude Area Defense. Those weapons would be linked with the radars and missiles carried aboard American Aegis warships in nearby waters.
There is a similar effort in the Pacific centered on radars in Japan, Aegis warships at sea and land-based interceptors in Alaska and California.
The Obama administration’s more recent focus has been the system to protect NATO allies in Europe with advanced radars based in Turkey and long-range interceptors to be based first in Romania and subsequently in Poland. American officials have emphasized that the limited number of interceptors in Europe are all about Iran, and would be inadequate to blunt Russia’s vast nuclear arsenal; but the system remains an irritant in relations with Moscow.
During the conflict with Hamas, Israeli officials report that Iron Dome knocked down more than 400 rockets on flight paths to populated areas, with a kill rate of 85 percent. Hamas is said to have fired off more than 1,400 rockets in all, but Israel was able to limit Hamas’s ability to launch more of its arsenal of 12,000 rockets with pre-emptive attacks on the storehouses where they were kept.
But some antimissile experts have expressed doubt about Israeli claims for Iron Dome, which is built by Israeli defense firms but has received about $275 million in financial support from the United States. Bright flashes can create a visual impression of overwhelming interceptor success, when in fact they may represent nothing more than the interceptor warhead blowing up, these skeptics warn.
“I’ve met the guys in Israel, and they’re smart,” said Richard M. Lloyd, an antimissile expert with more than a dozen patents and two major textbooks on warhead design to his credit. “But I’m not seeing the things I want to see” to prove that Iron Dome actually succeeded to the extent described by Israel.
Mr. Lloyd, who works for Tesla Laboratories Inc., a defense contractor in Arlington, Va., said he had studied dozens of publicly available photographs of spent rockets that landed on Israel. Few of them, he said, showed signs of damage from Iron Dome’s exploding warhead and the specific mechanism by which the interceptor is designed to make its kill — a dense spray of speeding metal fragments.
He acknowledged that some of the photographs may have been of enemy rockets that Iron Dome had not targeted because they were not headed toward populated areas. “I’m not saying the system is no good,” he stressed. “I’m saying I need more information.”
The president of Tesla Laboratories, George Stejic, echoed the doubts and said that the Israelis might have been tempted to exaggerate the degree of antimissile success as a calculated maneuver. “From a military perspective, the Israelis have every interest in overstating the efficacy of the system in order to deter missile launches,” he said. Israeli officials reject such skepticism, and stand by the statistics of Iron Dome’s success that they have released.
“The numbers are very accurate,” said one Israeli official who discussed sensitive internal assessments of Iron Dome on the condition of anonymity. “Many of these video clips and pictures were taken by citizens, not professionals. You cannot learn very much from videos taken with an iPhone.”
Iron Dome is wholly different from what would be required to defend a nation against long-range launchings by Iran or North Korea, even with their limited arsenals of those weapons, and it would do nothing to defend against a larger arsenal of intercontinental warheads, likely accompanied by decoys, from nations like Russia or China.
But South Korea has expressed interest in buying Iron Dome to defend the populated areas that have pushed toward the border with North Korea, which fields thousands of short-range rockets. Officials say Singapore has also been in discussions to purchase Iron Dome.
Israel acknowledges that Iron Dome is insufficient for its full missile-defense needs, and development is under way for David’s Sling, an antimissile system against medium-range rockets like those fielded by Hezbollah in Lebanon. An Arrow system is in the field to watch for a potential missile attack by a more distant Iran.
Missile defense enthusiasts in the United States now urge the American military to consider Iron Dome for support of ground units like those deployed in Afghanistan. “I think the successes of Iron Dome create a pretty big opening,” said Riki Ellison, chairman of the Missile Defense Advocacy Alliance.

NASA Great Observatories Find Candidate for Most Distant Object in the Universe to Date #Space

By combining the power of NASA's Hubble and Spitzer space telescopes and one of nature's own natural "zoom lenses" in space, astronomers have set a new record for finding the most distant galaxy seen in the universe.

The newly discovered galaxy, named MACS0647-JD, is very young and only a tiny fraction of the size of our Milky Way. The object is observed 420 million years after the big bang. The inset at left shows a close-up of the young dwarf galaxy. This image is a composite taken with Hubble's WFC 3 and ACS on Oct. 5 and Nov. 29, 2011. Credit: NASA, ESA, and M. Postman and D. Coe (STScI) and CLASH Team.

The farthest galaxy appears as a diminutive blob that is only a tiny fraction of the size of our Milky Way galaxy. But it offers a peek back into a time when the universe was 3 percent of its present age of 13.7 billion years.The newly discovered galaxy, named MACS0647-JD, was observed 420 million years after the big bang, the theorized beginning of the universe. Its light has traveled 13.3 billion years to reach Earth.
This find is the latest discovery from a program that uses natural zoom lenses to reveal distant galaxies in the early universe. The Cluster Lensing And Supernova Survey with Hubble (CLASH),an international group led by Marc Postman of the Space Telescope Science Institute in Baltimore, Md., is using massive galaxy clusters as cosmic telescopes to magnify distant galaxies behind them. This effect is called gravitational lensing.

Along the way, 8 billion years into its journey, light from MACS0647-JD took a detour along multiple paths around the massive galaxy cluster MACS J0647+7015. Without the cluster's magnification powers, astronomers would not have seen this remote galaxy.Because of gravitational lensing, the CLASH research team was able to observe three magnified images of MACS0647-JD with the Hubble telescope. The cluster's gravity boosted the light from the faraway galaxy, making the images appear about eight, seven, and two times brighter than they otherwise would that enabled astronomers to detect the galaxy more efficiently and with greater confidence.
"This cluster does what no manmade telescope can do," said Postman. "Without the magnification, it would require a Herculean effort to observe this galaxy."
MACS0647-JD is so small it may be in the first steps of forming a larger galaxy. An analysis shows the galaxy is less than 600 light-years wide. Based on observations of somewhat closer galaxies, astronomers estimate that a typical galaxy of a similar age should be about 2,000 light-years wide. For comparison, the Large Magellanic Cloud, a dwarf galaxy companion to the Milky Way, is 14,000 light-years wide. Our Milky Way is 150,000 light-years across.
"This object may be one of many building blocks of a galaxy,"said the study's lead author, Dan Coe of the Space Telescope Science Institute. "Over the next 13 billion years, it may have dozens, hundreds, or even thousands of merging events with other galaxies and galaxy fragments."
The galaxy was observed with 17 filters,spanning near-ultraviolet to near-infrared wavelengths, using Hubble's Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). Coe, a CLASH team member, discovered the galaxy in February while poring over a catalogue of thousands of gravitationally lensed objects found in Hubble observations of 17 clusters in the CLASH survey.But the galaxy appeared only in the two reddest filters.
"So either MACS0647-JD is a very red object, only shining at red wavelengths, or it is extremely distant and its light has been 'redshifted' to these wavelengths, or some combination of the two," Coe said. "We considered this full range of possibilities."
The CLASH team identified multiple images of eight galaxies lensed by the galaxy cluster. Their positions allowed the team to produce a map of the cluster's mass, which is primarily composed of dark matter. Dark matter is an invisible form of matter that makes up the bulk of the universe's mass. "It's like a big puzzle," said Coe. "We have to arrange the mass in the cluster so that it deflects the light of each galaxy to the positions observed." The team's analysis revealed that the cluster's mass distribution produced three lensed images of MACS0647-JD at the positions and relative brightness observed in the Hubble image.
Coe and his collaborators spent months systematically ruling out these other alternative explanations for the object's identity, including red stars, brown dwarfs, and red (old or dusty) galaxies at intermediate distances from Earth. They concluded that a very distant galaxy was the correct explanation.
The paper will appear in the Dec. 20 issue of The Astrophysical Journal.
Redshift is a consequence of the expansion of space over cosmic time. Astronomers study the distant universe in near-infrared light because the expansion of space stretches ultraviolet and visible light from galaxies into infrared wavelengths. Coe estimates MACS0647-JD has a redshift of 11, the highest yet observed.
Images of the galaxy at longer wavelengths obtained with the Spitzer Space Telescope played a key role in the analysis. If the object were intrinsically red, it would appear bright in the Spitzer images. Instead, the galaxy barely was detected, if at all, indicating its great distance. The research team plans to use Spitzer to obtain deeper observations of the galaxy, which should yield confident detections as well as estimates of the object's age and dust content.
MACS0647-JD galaxy, however, may be too far away for any current telescope to confirm the distance based on spectroscopy, which spreads out an object's light into thousands of colors. Nevertheless, Coe is confident the fledgling galaxy is the new distance champion based on its unique colors and the research team's extensive analysis. "All three of the lensed galaxy images match fairly well and are in positions you would expect for a galaxy at that remote distance when you look at the predictions from our best lens models for this cluster," Coe said.
The new distance champion is the second remote galaxy uncovered in the CLASH survey, a multi-wavelength census of 25 hefty galaxy clusters with Hubble's ACS and WFC3. Earlier this year, the CLASH team announced the discovery of a galaxy that existed when the universe was 490 million years old, 70 million years later than the new record-breaking galaxy. So far, the survey has completed observations for 20 of the 25 clusters.
The team hopes to use Hubble to search for more dwarf galaxies at these early epochs. If these infant galaxies are numerous, then they could have provided the energy to burn off the fog of hydrogen that blanketed the universe, a process called re-ionization. Re-ionization ultimately made the universe transparent to light.

Mission 26 The Big #Endeavour - #Space

Great Time lapse video showing the Space Shuttle Endeavour's its last trip through Los Angeles.


Mission 26 The Big Endeavour from Givot on Vimeo.
A very special thanks to the City of Inglewood, Chief of Police Mark Fronterotta, Lieutenant James Madia, Sergeant Dirk Dewachter, and to the Men and Women of the Inglewood Police Department. None of this would have been possible without them.

This project was only made possible by the help of a truly amazing and talented timelapse team which included; Joe Capra, Chris Pritchard, Brian Hawkins, Andrew Walker, Ryan Killackey and myself.
This truly was a once in a lifetime opportunity that we are so happy and honored to have been be a part of.

The endeavor started on Thursday night and went on until Sunday night, with very little sleep to no sleep. The only thing that kept us going was pure love of the art and adrenaline. One thing that stood out the most for me, while I was shooting, was the people of Los Angeles. It was so powerful to see the excitement on peoples faces and the pride of their home town. No matter how many times I would see the Shuttle it would never get old.

This has been an amazing experience that I will never forget. My hope is that this film will show you the amount of dedicated people and teamwork that it took to get the Endeavour to its new home. Enjoy.

Obituary: Neil #Armstrong | The Economist

Obituary

Neil Armstrong 

ASTRONAUTS do not like to be called heroes
“I am, and ever will be, a white-socks, pocket-protector, nerdy engineer, born under the second law of thermodynamics, steeped in steam tables, in love with free-body diagrams, transformed by Laplace and propelled by compressible flow.”
 Armstrong was known as the “Ice Commander”
Aug 25th 2012, 20:38 by T.C. 


ASTRONAUTS do not like to be called heroes. Their standard riposte to such accusations is to point out that it requires the efforts of hundreds of thousands of backroom engineers, mathematicians and technicians to make space flight possible. They are right, too: at the height of its pomp, in 1966, NASA was spending about 4.4% of the American government’s entire budget, employing something like 400,000 workers among the agency and its contractors.
But it never works. For Neil Armstrong, who commanded Apollo 11, the mission that landed men on the moon on July 20th 1969, the struggle against heroism seemed particularly futile. The achievement of his crew, relayed live on television, held the entire planet spellbound. On their return to Earth, the astronauts were mobbed. Presidents, prime ministers and kings jostled to be seen with them. Schools, buildings and roads were named after them. Medals were showered upon them. A whirlwind post-flight tour took them to 25 countries in 35 days.
As the first man to walk on another world, Armstrong received the lion’s share of the adulation. All the while, he quietly insisted that the popular image of the hard-charging astronaut braving mortal danger the way other men might brave a trip to the dentist was exaggerated. “For heaven’s sake, I loathe danger,” he told one interviewer before his fateful flight. Done properly, he opined, spaceflight ought to be no more dangerous than mixing a milkshake.
Indeed, the popular image of the “right stuff” possessed by the astronaut corps—the bravery, the competitiveness, the swaggering machismo—was never the full story. The symbol of the test-pilot school at Edwards Air Force Base in the Mojave desert, where Armstrong spent years testing military jets, is a slide rule over a stylised fighter jet. In an address to America’s National Press Club in 2000, Armstrong offered the following self-portrait: “I am, and ever will be, a white-socks, pocket-protector, nerdy engineer, born under the second law of thermodynamics, steeped in steam tables, in love with free-body diagrams, transformed by Laplace and propelled by compressible flow.”
He had an engineer’s reserve, mixed with a natural shyness. Even among the other astronauts, not renowned for their excitability, Armstrong was known as the “Ice Commander”. Mike Collins, one of Armstrong’s crew-mates on the historic moon mission, liked his commander but mused that “Neil never transmits anything but the surface layer, and that only sparingly.” In one famous incident, Armstrong lost control of an unwieldy contraption nicknamed the “Flying Bedstead” that was designed to help astronauts train for the lunar landing. Ejecting only seconds before his craft hit the ground and exploded, Armstrong dusted himself off and coolly went back to his office for the rest of the day, presumably to finish up some paperwork.
That unflappability served him well during the lunar landing. The original landing area turned out to be full of large boulders, and so Armstrong had to take control from his spacecraft’s primitive computer and skim across the lunar surface by hand, looking for somewhere suitable to set down. By the time he found his spot, there was only 25 seconds of fuel left in the tanks.
It served him well back on Earth, too. The astronauts knew from the experiences of their predecessors on the Mercury and Gemini flights that their trip would transform them into celebrities. But theirs was the biggest achivement yet, and none were prepared for the adulation that awaited them. Puzzlingly for the pragmatic spacemen, their trip to the moon seemed to have elevated them to the status of oracles, and people pressed them for their thoughts on everything from religion to the future of the human species and the chances for world peace.
Unlike some of his fellow astronauts (two of whom became senators), Armstrong chose a comparatively quiet retirement, teaching engineering at the University of Cincinnati. He returned to NASA twice, both times to serve on boards of enquiry, the first into the near-disaster of Apollo 13, and the second into the disintegration of the space shuttle Challenger in 1986. He spent his final years on his farm in rural Ohio, flying gliders in his spare time (it was, said the supposedly emotionless engineer, the closest humans could come to being birds).
For all mankind
Half a century after the event, with the deaths of many of its participants, the Apollo project is beginning to fade from living memory and pass into the history books. It was one of the mightiest achievements of the potent combination of big government and big science; in many ways the apotheosis of the post-war American political consensus. Viewed from an age in which America’s government aspires to smallness and in which grand projects are regarded with suspicion, it seems more alien with every passing year.
Nevertheless, it is one of the few events of the 20th century that stands any chance of being widely remembered in the 30th. Despite its origins in Cold War paranoia and nationalist rivalry, Mike Collins recalls in interviews a brief moment of global unity: “People, instead of saying ‘you Americans did it’, they said ‘we—people—did it’. I thought that was a wonderful thing. Ephemeral, but wonderful.”
Perhaps the most unexpected consequence of the moon flights was a transformation of attitudes towards Earth itself. Space was indeed beautiful, but it was beauty of a severe, geometrical sort. Planets and stars swept through the cosmos in obedience to Isaac Newton’s mathematical clockwork, a spectacle more likely to inspire awe than love. Earth was a magnificent contrast, a jewel hung in utter darkness, an exuberant riot of chaos and life in a haunting, abyssal emptiness. The sight had a profound effect on the astronauts, and photos of the whole Earth, which had never been seen before, nourished the nascent green movement.
As for the man himself, his reserve was not limitless. One of the most famous photos of Armstrong shows the Ice Commander in the Lunar Module after he and Buzz Aldrin had completed their historic walk on the moon’s surface. He is dressed in his space-suit, sports a three-day beard and is clearly exhausted. And on his face is plastered a grin of purest exhilaration.

A Flight Through the #Universe, by the Sloan Digital #Sky Survey

An Incredible 3D rendition of 4 billion years of time in over 1MM galaxies


The Sloan Digital Sky Survey III (SDSS-III) has released the largest three-dimensional map of massive galaxies and distant black holes ever created. The new map pinpoints the locations and distances of over a million galaxies. It covers a total volume equivalent to that of a cube four billion light-years on a side.

“We want to map the largest volume of the universe yet, and to use that map to understand how the expansion of the universe is accelerating,” said Daniel Eisenstein of the Harvard-Smithsonian Center for Astrophysics. Eisenstein is the director of SDSS-III.

The map is the centerpiece of Data Release 9 (DR9), which publicly releases the data from the first two years of a six-year survey project. The release includes images of 200 million galaxies and spectra of 1.35 million galaxies. (Spectra take more time to collect than photographs, but provide the crucial third dimension by letting astronomers measure galaxy distances.)

“Our goal is to create a catalog that will be used long after we are done,” said Michael Blanton of New York University, who led the team that prepared Data Release 9.

"Soccer Ball" Nebula Discovered by Amateur Astronomer

Amateur astronomer Matthias Kronberger discovered the soccer-ball nebula, called Kronberger 61, in January 2011 after poring over digitized photos of sky surveys from the 1980s. After he alerted professional astronomers, the Gemini Observatory in Hawaii zoomed in on the region to create the new, color-composite image.
Kronberger 61 lies roughly 13,000 light-years away in the Cygnus constellation and is almost perfectly round—an oddity when compared with the other 3,000 or so planetary nebulae already discovered.
"Very few are this spherical. They're usually elongated and look like butterflies and other objects," said astronomer George Jacoby of the Giant Magellan Telescope Organization in Pasadena, California, who helped image the nebula with Gemini.

Space Shuttles on Offer

For Sale: NASA Space Shuttle
Condition: 27 years old, 150 million miles traveled, somewhat dinged but well maintained.

The space shuttle Discovery on its 39th and final flight.

Price: $0.

Dealer preparation and destination charges: $28.8 million.

So, does anyone want to buy a used space shuttle?

Yes, it turns out. This old vehicle — the space shuttle Discovery — is an object of fervent desire for museums around the country, which would love to add it or one of its mates, the Endeavour and the Atlantis, to their collections. (Financing terms can be arranged with NASA.)

The Discovery is to return from orbit on Wednesday, concluding its 39th flight and its space-faring career, but it will make at least one more ascent — piggyback on a 747 airplane — to its resting place for public display. NASA will announce the final destinations for the three soon-to-be-retired shuttles on April 12, the 30th anniversary of the first space shuttle launching.

Some of the competing institutions have been campaigning energetically.

The visitor center at NASA’s Johnson Space Center in Houston hired a marketing firm and set up a Web site, bringtheshuttlehome.com. Houston, the marketers argue, is the location of NASA’s Mission Control, which guides the shuttles during flight. For the Texans, owning a space shuttle would be “the modern-day equivalent of housing Columbus’ famed ships — the Nina, the Pinta or the Santa Maria,” the Web site states.

The Intrepid Sea, Air and Space Museum in Manhattan has collected more than 150,000 names on a petition urging that one of the shuttles be placed there. “New York City would make an ideal home for one of these retiring shuttles,” the campaign asserts, noting that the spacecraft would be “prominently displayed” on Pier 86 in Manhattan.

The Museum of Flight in Seattle has perhaps gone the furthest: this week, it erected the first wall of a new $12 million wing to house the shuttle it may never get. The museum’s “shuttle boosters” Web site argues that Seattle has “the right stuff” because the Boeing 747 was built there and 27 shuttle astronauts have called Washington home. (Officials at the Seattle museum say they have planned for the possibility of not getting a shuttle and would fill the space with other space artifacts.)

No one knows if these efforts, or dueling letters from various members of Congress, are exerting any sway on the top decision-maker at NASA, Maj. Gen. Charles F. Bolden Jr., who has said that he alone will decide where the shuttles end up.

NASA says that 21 institutions have submitted proposals.

“We’re waiting,” said Susan Marenoff, president of the Intrepid Museum. “We’re hoping.”

Other hopefuls include the Kennedy Space Center in Florida, the launching site of all of the shuttle missions; the California Science Center in Los Angeles; and the Museum of the United States Air Force, near Dayton, Ohio, which got a boost from President Obama’s budget request for 2012 seeking $14 million to send a shuttle there.

“There are more favorites than there are shuttles,” said Robert Pearlman, editor of CollectSpace.com, a Web site for space history enthusiasts.

One museum that has been mum is the Smithsonian’s National Air and Space Museum. But that is because NASA already offered it the Discovery three years ago, and most expect the Discovery will go there. After concerns last year that the Smithsonian could not afford $28.8 million, Congress, in a budget bill passed in December, included a clause that specifically excuses the Smithsonian from those costs. If NASA offered a shuttle to the Smithsonian, the bill decreed, it would be “at no or nominal cost.”

The Smithsonian, however, has been reticent about its intentions, and a spokeswoman offered only a short statement: “The museum is involved in discussions with NASA about transfer of the orbiter and other artifacts from the shuttle program. The final disposition of shuttle artifacts will be the decision of NASA.”

After the Discovery lands, only two shuttle flights remain. The Endeavour is scheduled to launch in April, and the Atlantis in June. Then the three will become museum pieces, with delivery expected next year. Each weighs about 170,000 pounds and is 122 feet long, with a wingspan of 78 feet.

There is also a fourth orbiter, the Enterprise, which was used for early glide tests but never went to space. The Air and Space Museum has the Enterprise on display at its spacious Steven F. Udvar-Hazy Center near Washington-Dulles Airport. If the Discovery goes to the Smithsonian as expected, the Enterprise would likely get bumped to a new home, a consolation prize for one of the museums that did not receive a space-traveled shuttle.

A couple of years ago, NASA inquired if any museums or other institutions had an interest in acquiring one of the three flying space shuttles. Potential bidders were told that educational programs had to accompany the exhibits, and that the shuttles had to reside in an indoor, climate-controlled environment. (NASA does not want to repeat the mistake at the end of the Apollo era, when the remaining Saturn V rockets rusted and decayed outdoors.)

Since then, NASA has been mostly silent.

“We’ve not been contacted since we submitted,” said Richard E. Allen Jr., chief executive of Space Center Houston, the visitor center at Johnson.

After it lands, the Discovery will go through a month of postflight rituals, like the removal of payloads. But then, instead of beginning preparations for another flight, workers will start primping it for its life as a tourist attraction. That work — which accounts for most of the $28.8 million that NASA is charging — will include cleaning or removing parts that have been contaminated by toxic propellants, and will likely take nine months to a year.

The visitor complex at the Kennedy Space Center has proposed what would probably the most ambitious display: While most of the museums would have the orbiter sitting on the ground and build a fancy hangar around it, Kennedy would like to suspend it horizontally as if it were in Earth’s orbit, with the payload doors open and the robotic arm sticking out. It would the centerpiece of a $100 million, 64,000-square-foot exhibit that would open in the second half of 2013.

“We want to show it in flight,” said William Moore, the chief operating officer of the visitor center, which operates under contract with NASA without government funding, “and so the exhibit is really based around the shuttle working, because it’s a working vehicle and has done a lot of great things.”

Mr. Moore said he was confident that his institution would be one of the recipients. “You should be sure to call me back on April the 13th about how we feel when we get an orbiter,” he said.

However, for all his confidence, Mr. Moore admitted that he had no idea what General Bolden was thinking. “We read the newspaper a lot,” he said. “NASA has been very close-lipped about this. We really don’t have any inside scoop at all.”
