Hubble's Amazing Rescue

TV Program Description
Premiere Broadcast on PBS: October 13, 2009

The best-known scientific instrument in history was dying. After nearly 20 years in space and hundreds of thousands of spectacular images, the Hubble Space Telescope's gyroscopes and sensors were failing, its batteries running down, and some of its instruments were already dead. The only hope to save Hubble was a mission so dangerous that in 2004 NASA cancelled it because it was considered too risky.

Scientists and the general public alike stubbornly refused to abandon the telescope, and a new NASA administrator revived the mission. This program takes viewers behind the scenes on a riveting journey with the team of astronauts and engineers charged with saving the famous "orbiting observatory" against all odds.

Hubble had been serviced four times before, including the famous 1993 repair mission that had corrected its blurred vision. But all previous missions had involved replacements, not actual repairs. Astronauts undid latches, removed a balky module, and replaced it with a new one. This mission would be different. Two of Hubble's instruments—a camera and a spectrograph—had died, and no replacements existed. To revive them, astronauts would attempt procedures never before tried in space: opening up electronic assemblies, getting "into the guts," and performing delicate tasks previously thought impossible.

In his latest film for NOVA, Rushmore DeNooyer weaves together the compelling story of this dangerous 12-day mission and its five pressure-filled spacewalks. Spacewalks are exhausting. Astronauts must work in cramped quarters and darkness while wearing a clumsy spacesuit. Suits are pressurized and stiff, and every movement takes concentrated effort. The work is hardest on the hands; moving fingers is like squeezing a tennis ball. After eight continuous hours of exertion, it's not uncommon for a spacewalker's fingernails to turn black and blue and fall off. And it would all have to be done in weightlessness, where everything floats and nothing stays put. In space, a single screw floating loose into Hubble could ruin the telescope. (Hear astronaut John Grunsfeld explain why fixing Hubble is all about the gloves.)

"At first it sounded like this would be impossible," recalls lead spacewalker Mike Massimino. Mission Director Chuck Shaw compares the work to neurosurgery.

For two years leading up to launch, filmmakers followed the mission closely, with unprecedented access to every aspect of the endeavor, from NASA's training facilities for flight preparation to the historic mission itself. DeNooyer and his production team followed all seven astronauts—Scott Altman, Andrew Feustel, Michael Good, Gregory Johnson, and Megan McArthur as well as Grunsfeld and Massimino—as they trained extensively. He chronicled them experiencing virtual weightlessness at the Neutral Buoyancy Laboratory at the Johnson Space Center in Houston and practicing best procedures for the crucial spacewalks. (In a video short, hear Mike Massimino talk about the challenges of working in space.)

Following the May 2009 launch from the Kennedy Space Center in Florida, the crew traveled 5,276,000 statute miles in 197 Earth orbits. NOVA viewers see Hubble pulled from its own orbit by the Atlantis shuttle's huge robotic arm and moved into the spacecraft's payload bay, where it remains during nearly 37 hours of painstaking repairs. The Atlantis crew followed a meticulously crafted script, two years in the making, in order to stay on schedule, each spacewalk carefully timed based on oxygen supply and physical strength.

After all tasks were completed, Hubble was gently released back into space, now 10 to 70 times more powerful than when it was first launched—reaffirming its role as a vital scientific resource. While "Hubble's Amazing Rescue" documents the end of space shuttle missions to the world-famous telescope, it also excites viewers about new images, information, and insights that will emerge from the powerful upgrades. DeNooyer, a veteran NOVA producer, describes Hubble as "a time machine that shows us how the universe looked when it was still young." (See DeNooyer's dispatches about the mission as it unfolded.)

After years of training, the astronauts on the 2009 Hubble mission made it look easy, but repairing the Space Telescope involved five long, risky spacewalks and intricate repairs never before attempted in space.
