You can’t cancel an enormous federal program without hitting pushback, and President Obama is hitting plenty of it over his proposal to end NASA’s Constellation program. In January his budget proposal put forth no funding for Constellation, the space shuttle successor program that included the Ares rockets, Orion crew capsule, and plans to send astronauts back to the moon by 2020. Instead, NASA would become more reliant on private companies to ferry its astronauts to the space station, and would explore new ideas for visiting Mars or nearby asteroids. But the proposal has already ruffled lots of feathers, prompting the President to say he will hold a conference to further outline his plan.
First, many high-profile space experts balked at the proposal. Former astronaut Tom Jones said Obama was surrendering human spaceflight, and Apollo 17 astronaut Harrison Schmitt, one of the last men to walk on the moon, was equally displeased. “It’s bad for the country,” Schmitt said. “This administration really does not believe in American exceptionalism” [Washington Post]. Dissent wasn’t universal; DISCOVER blogger Phil Plait, for one, praised the possibilities for commercial space-faring.

The International Space Station is almost done. Astronauts on board the current space shuttle Endeavour completed the first of three spacewalks to install the last major component of the ISS: the Tranquility module. Its huge windows will offer ISS residents 360-degree view of space, the station, and our home world.
The U.S. Tranquility module — shaped like a soda can — is the last major American addition to the station, now 98% complete. Its placement completes 11 years of U.S. construction work on the outpost, which the United States has spent more than $50 billion building [USA Today]. An Italian team designed the module’s magnificent dome, which measures 10 feet in diameter. Seven windows provide the panoramic view.

The Obama administration’s new budget may come in at a hulking $3.8 trillion, but one thing it doesn’t include is continued funding for the Constellation program. The program, which was intended to continue the work of the aging space shuttles, will get the ax if Congress approves the President’s plan. This also means that NASA would abandon its goal of returning to the moon by 2020.
Obama’s budget ends work on the shuttle follow-on vehicle, known as Orion, as well as a pair of rockets developed to fly astronauts to the space station, the moon and other destinations in the solar system. “We are proposing canceling the program, not delaying it,” Peter Orszag, director of the Office of Management and Budget, told reporters [Reuters]. The announcement had been some time in coming: The Augustine panel that Obama convened last year to review human spaceflight concluded that Constellation couldn’t succeed without $3 billion in additional annual funding, and rumors broke out last week that the President’s budget would kill the program for good.
In place of the Constellation program’s Ares rockets and Orion crew capsule, Obama’s plan calls for funneling money to private companies that are jockeying for NASA contracts. The Washington Post reports that the plan would funnel $6 billion to support private space companies developing a vehicle to ferry astronauts back and forth from the International Space Station. Companies expected to seek the new space taxi business include United Launch Alliance, a partnership between Boeing and Lockheed Martin that launches rockets for theUnited States Air Force, and Space Exploration Technologies, a start-up company led by Elon Musk, who founded PayPal [ The New York Times]. The plan would also extend the life of the space station until 2020.
Commercial Spaceflight Federation president Bretton Alexander was understandably giddy at the prospect of private companies taking center stage. “At a time when job creation is the top priority for our nation, a commercial crew programme will create more jobs per dollar because it leverages millions in private investment and taps the potential of systems that serve both government and private customers,” he said [BBC News].

NASA’s Ares I-X experimental rocket completed its first test flight—but the successful endeavor ended on a sour note. The rocket’s first booster stage, which splashed down in the ocean as planned six minutes after launch, was found to be significantly dented when divers reached the mammoth cylinder to prep it for retrieval [Scientific American]. A malfunctioning parachute system caused the hard splashdown, according to mission manager Bob Ess. However Ess argued that it’s not a real cause for concern, since test flights are intended to reveal and work out the technology’s glitches.
The Ares I-X was a prototype for the controversial Ares I rocket that may carry astronauts to the International Space Station and beyond once the space shuttle is retired. The rocket’s design calls for the first booster stage to be retrieved after each flight for reuse. While NASA’s main objective on the test flight was to evaluate the rocket booster’s power, the test of the new parachute system was one of several major objectives of the Ares 1-X test flight [Spaceflight Now]. Despite the test flight’s overall success, the parachute system’s failure is a black eye for the $450 million project, since the heavy Ares I booster rocket will be difficult to ease back down to Earth. The booster is being retrieved from the Atlantic Ocean to determine what exactly went wrong with the parachute system.

This morning, NASA’s experimental Ares I-X rocket blasted off a Florida launch pad and roared through the atmosphere, successfully executing the first test flight of the rocket that may carry astronauts to the International Space Station and beyond once the space shuttle is retired. However, debate over the direction of NASA’s manned space flight program means that the rocket’s future is far from certain.
The prototype rocket took off through a few clouds from a former shuttle launch pad at 11:30 a.m., 3 1/2 hours late because of bad weather. Launch controllers had to retest the rocket systems after more than 150 lightning strikes were reported around the pad overnight. Then they had to wait out interfering rain clouds, the same kind that thwarted Tuesday’s try [AP].
Engineers had been concerned that if the rocket took off through rain clouds, the moisture might cause a phenomenon called triboelectrification. This occurs when the rocket encounters water or ice droplets in the clouds. As these collide with the rocket they cause a static charge to build up on its skin, creating interference with radio signals. This is a problem for the 1-X team, which needs clear signals to gather data from 700 sensors wired throughout the vehicle, which are designed to collect flight data [BBC News]. Luckily, the late morning provided a relatively cloud-free window for takeoff.

Even as engineers prepare for the first test flight of NASA’s new Ares I-X rocket, a prototype of the launch vehicle that could replace the space shuttle, the experts who conducted a review of NASA’s space flight program are suggesting that this rocket project should be scrapped entirely.
The test flight of the $450 million Ares I-X is scheduled for 8 a.m. tomorrow, weather permitting. It’s a prototype of the planned Ares I rocket, designed to carry astronauts to the International Space Station once the shuttle fleet is retired. But the White House panel convened to evaluate NASA’s plan for space exploration issued its final report (pdf) on Thursday, and in a press conference committee chair Norman Augustine harshly critiqued the Ares I project. Though Augustine said the rocket’s technical problems were solvable, he said its first crewed flights would come too late to be much help in servicing the International Space Station (ISS). “The issue that comes up under Ares I is whether the programme is useful,” he said [New Scientist].

A prototype of the rocket that may blast astronauts into space once the space shuttle is finally retired will get a high-profile test flight next week, and this morning the tall, skinny rocket was rolled onto the launch pad in Florida. While the experimental Ares I-X rocket certainly looked grand as it was rolled slowly from the assembly building to the launch pad (a four-mile trip that took seven hours), its future is far from certain. A White House panel has been considering cancelling Ares I in favour of a commercial launcher. Its final report is expected this week [New Scientist].
NASA’s new sky-scraping rocket measures 327 feet high; it dwarfs the space shuttles, which measure 184 feet high. “It’s a tall rocket; it’s been over three decades since anyone has built a rocket this tall. That was the Saturn V,” explained Trent Smith, the vehicle processing engineer for the Ares 1-X. “We have over 700 sensors on this rocket; and the whole point of Ares 1-X is to understand how does a rocket this shape, this weight, this tall actually fly” [BBC News].

NASA has successfully tested an inflatable heat shield for the first time, which could offer an excellent alternative to the rigid heat-resistant tiles and carbon coatings used by current spacecraft. On Monday, NASA engineers lofted a vacuum-packed shroud atop a small sounding rocket from NASA’s Wallops Flight Facility on Wallops Island, Va. Several minutes after liftoff, the shield inflated to a 10-foot-diameter mushroom shape [LiveScience]. The inflation system, which lead scientist Neil Cheatwood calls “a glorified scuba tank,” filled the shield in less than 90 seconds. The shield then fell back to Earth, surviving the fiery reentry into the atmosphere and splashing down in the Atlantic.
The experimental system offers several potential advantages. The fragile heat-resistant tiles that cover the space shuttle need frequent inspections and repairs to prevent another tragedy like the 2003 breakup of the Columbia, while the inflatable shield could be stowed safely away until its needed. The inflatable shield’s low mass also allows spacecraft to carry more or heavier payloads. “Right now the rigid ones are at the weight limit of what we’re trying to send to Mars,” [engineer Robert] Dillman says. “If you want to take larger payloads to Mars, they’ll have to either do something quite creative or switch to an inflatable” [New Scientist].

As of tomorrow, 101 years will have passed since the Tunguska Event, the mysterious explosion that flattened 800 square miles of Siberian forest. Just in time for the anniversary researchers have come up with yet another explanation for what may have caused the baffling blast. Previously, researchers best hypothesis was that a meteor struck the forest, but scientific expeditions failed to turn up an impact crater or any fragments of rock. The new hypothesis, which will be published in the journal Geophysical Research Letters, suggests that the Earth was hit by the icy core of a comet, which exploded in the atmosphere.
Researchers say that a comet strike would have released huge volumes of water vapour at very high altitude, creating highly reflective clouds that may explain why the sky was lit up for days after the collision, with people as far away as London saying that they could read newspapers outdoors at midnight, the scientists said [The Independent]. In an unusual twist, the evidence for the new theory comes from studies of the water vapor exhaust created by space shuttle launches.

The man tasked with steering NASA through difficult transitions and pointing the space agency boldly towards the stars will be a former astronaut who has piloted the space shuttle. On Saturday, President Barack Obama announced his long-awaited nomination for NASA administrator: Charles F. Bolden Jr. If confirmed by the Senate, the former astronaut and retired Marine Corps general will be the first African-American to head the space agency.
The pick has been celebrated by NASA insiders, and is viewed as a signal that, after some signs of ambivalence, President Obama is now embracing the expensive manned spaceflight program. “Clearly Charlie Bolden would not have taken the job if he were being asked to shut down human spaceflight,” said John Logsdon, a space policy expert in Washington…. He added that a recent announcement of the administration’s plans to review the Ares 1 rocket and Orion spacecraft, which are to replace the space shuttle by 2015, is not a shot across the bow of NASA’s human spaceflight program. He said it would be a review of the hardware, not the destination or goals [Los Angeles Times].
However, it is not clear whether the new leadership will adopt all of the goals for human exploration of the solar system that were laid out by the Bush administration: namely, returning to the moon by 2020 and then working towards landing humans on Mars.

This morning, 350 miles above the Atlantic Ocean, a tender goodbye took place. Astronauts aboard the Atlantis space shuttle released the Hubble Space Telescope to conclude the telescope’s fifth and final repair mission. The better-than-new observatory is expected to send back breathtaking images and mind-rattling information about the universe for another five to seven years. As the NASA officials in charge of the telescope put it: “Hubble is now ready to resume its role as humankind’s most powerful eyes on the universe” [AP].
During this mission, Atlantis astronauts spent more than 36 hours over five marathon spacewalks to make upgrades and outfit Hubble with new instruments. These included a panchromatic wide-field camera that should be able to see objects formed just 500 million years after the universe’s birth in the big bang explosion some 13.7 billion years ago [Reuters]. But there were occasional glitches: When a bolt wouldn’t come free on the Sunday spacewalk, astronaut Mike Massimino had to resort to brute force, jerking the railing that it held in place until the bolt snapped. There was also an ill-timed incident this morning involving an antenna.

Yesterday, about 350 miles above western Australia, two massively expensive pieces of space hardware rendezvoused in a delicate orbital dance. The space shuttle Atlantis arrived at the Hubble Space Telescope for the telescope’s fifth and final upgrade, and met the telescope in orbit as it circled the Earth at 17,200 miles per hour. With mission commander Scott Altman at the controls, Atlantis eased up within 30 feet of NASA’s flagship observatory, bringing the ship close enough for a capture attempt. Mission specialist Megan McArthur limbered up the shuttle’s robot arm and used snares at its end to latch on to a pin-like grapple fixture on the side of the gleaming telescope. “Houston, Atlantis. Hubble has arrived onboard Atlantis,” said Altman [Florida Today blog].
The astronauts audibly gasped as they drew up to the 12-ton telescope. “Just looking out the window here, and it’s an unbelievably beautiful sight,” said John M. Grunsfeld, a veteran astronaut. “Amazingly, the exterior of Hubble, an old man of 19 years in space, still looks in fantastic shape.” Dr. Grunsfeld, who is on his third Hubble repair trip, was one of the last humans to see the telescope in March 2002 and arguably knows it better than anyone on or above Earth [The New York Times].

At 2:01 this afternoon in Florida, the space shuttle Atlantis is expected to roar off its launch pad and set off toward the orbiting Hubble Space Telescope, for the fifth and final repair mission in the telescope’s history. The countdown timeline is on target, and “Atlantis is ready to fly,” said Charlie Blackwell-Thompson, NASA’s test director…. The 11-day mission will include five spacewalks to refurbish Hubble with state-of-the-art science instruments. After the upgrades, the telescope’s capabilities will be expanded, and its lifetime extended through at least 2014 [CNN].
The current mission carries a higher degree of danger than the space shuttle’s habitual jaunts to the International Space Station. Hubble orbits about 350 miles above Earth, in an area with a higher density of debris. Earlier this year two satellites collided over Siberia, which has increased the risk even more, as junk from that collision drifts lower [ABC News]. While NASA will track orbiting space junk as it always does, the agency has also taken the precaution of getting the space shuttle Endeavor ready for launch on another pad in case a rescue operation is necessary.
NASA will cover the launch live on NASA TV, and DISCOVER’s own Bad Astronomy blogger, Phil Plait, will be posting updates on his breaking news Twitter account.

While NASA’s central mission is the same as it always was–to send astronauts up, up, and away!–the details of how it will send bold explorers into the space frontier are suddenly, well, up in the air. After months of signaling displeasure with NASA’s operations, the Obama administration has ordered a 90-day review of the human space flight program. In a letter to NASA Acting Administrator Christopher Scolese, the president’s science adviser, John Holdren, wrote that “it would be only prudent” to review NASA’s human space flight program given the magnitude of its ambitions and “the significant investment of both funds and scientific capital” [Washington Post].
The crux of the matter is the Constellation program, which aims to replace the aging space shuttles with the newly designed Ares rockets and Orion crew capsule. But during the past several months, watchdog agencies have questioned whether NASA can deliver the Constellation program on time and within budget. Its estimated costs through 2015 have risen from $28 billion in 2006 to more than $40 billion today, and engineers still are wrestling with design flaws that would cause Ares I to shake violently during ascent and also possibly drift into its launch tower [Orlando Sentinel]. Back in December, Obama’s transition team reportedly asked NASA officials if military rockets used to launch satellites could be reconfigured to boost astronauts to the International Space Station and on to the moon.

Bureaucratic rules regarding who can use what equipment aboard the International Space Station are causing some hard feelings among the crew members, according to Russian cosmonaut Gennady Padalka, who gave an interview to Russia’s Novaya Gazeta newspaper before he blasted off towards the space station on Thursday. Padalka complained that regulations will prevent him from using his American colleagues’ exercise bike to stay fit in space. Worse than that, [officials] also ruled that American and Russian crew members should use their own “national toilets”, with Russian crew banned from using the luxurious American astro-loo [The Guardian].
Padalka said strict regulations that prevent the sharing of everything from food to toilets hurts the crew’s morale and makes working in space still more complicated. But he added that the crew will rise above the pettiness. “Cosmonauts are above the ongoing squabble, no matter what officials decide,” said Padalka, a veteran of two space missions, according to the newspaper. “We are grown-up, well-educated and good-mannered people and can use our own brains to create normal relationship. It’s politicians and bureaucrats who can’t reach agreement, not us, cosmonauts and astronauts” [AP].
