CAPE CANAVERAL, Fla. — With the safe landing of the Space Shuttle Endeavour after its final mission in space, NASA is another step closer to a looming deadline: the very last flight of the agency’s storied space shuttle program.
Endeavour landed June 1 at NASA’s Kennedy Space Center at 2:34 a.m. EDT to end a 16-day mission to the international space station. Yet in a symbolic handover, as Endeavour’s wheels rolled to a stop on Runway 15, another shuttle — Atlantis — made its last slow crawl to the launch pad for its final mission in early July.
NASA is hoping to launch Atlantis July 8 on a 12-day resupply mission to the international space station. Four astronauts — commander Chris Ferguson, pilot Doug Hurley and mission specialists Sandy Magnus and Rex Walheim — will fly Atlantis on what will be the grand finale of NASA’s shuttle program.
Endeavour’s STS-134 flight was the orbiter’s 25th and final mission, and delivered a $2 billion astrophysics experiment and extra supplies to the orbiting complex. Atlantis’ flight will be STS-135, the 135th and last mission for the shuttle program after more than 30 years of spaceflight.
Atlantis began its 5.5-kilometer trek from the cavernous Vehicle Assembly Building to the launch pad May 31 at 8:42 p.m. EDT. The roughly seven-hour journey ended at 3:29 a.m. EDT, about an hour after Endeavour touched down.
“Seeing Atlantis roll out was really when it started to hit me that we’re never going to see that again,” Mike Moses, chairman of the shuttle mission management team, said during a post-landing news briefing. “So that was a pretty big, emotional event. But again, it was tempered with turning around and focusing on landing.”
Having two shuttle milestones within close proximity to one another was a unique and special event that drew large crowds and also served as a poignant reminder of the program’s imminent end.
“It’s a very good day today, and I really want to thank the folks down here for all the dedication and hard work they put in,” said William Gerstenmaier, NASA associate administrator for space operations.
The plan for the future
After Atlantis returns to Earth, NASA’s space shuttle program will officially come to a close. NASA is ending its 30-year shuttle program to focus on developing new spaceships and rockets for exploration beyond low Earth orbit, such as missions to an asteroid, the Moon or Mars.
Yet, until the next-generation vehicles are ready, NASA faces a multiyear period during which the agency will have to rely on Russian-built Soyuz spacecraft to reach the international space station.
“Times of transition are very difficult, and we’re certainly in a time of transition,” Magnus said. “As we’re moving through the transition, it’s difficult to see the big picture because we’re all caught up in the little details. I think in the end, we’ll end up with a good plan and we’ll have a solid future ahead of us and we’re just working our way through this very difficult transition in the meantime.”
And while the legacy of the space shuttle program will live on, the program’s retirement will also signify the end of an iconic part of the country’s space program.
“I think we’re losing that piece of identity,” Walheim said. “That is a quintessential American vehicle. You point to that and people know it’s from the United States.”
But building upon the achievements of the space shuttle program and advancing human exploration require NASA to push farther out into the solar system, he said.
“As much as the space shuttle has done its mission to launch the interplanetary probes, to launch the Hubble Space Telescope, to build the space station — it’s complete,” Walheim said. “So it’s done its job, and it’s done its job admirably. Now it’s time to move onto something new. We’ve got to get out of low Earth orbit, so to do that we need a new vehicle.”
The space shuttle era will always be remembered as a critical chapter in the nation’s history, and Atlantis’ upcoming STS-135 flight will be a part of that rich heritage.
“I think we can look back and really take the sweet part of all this and say that we are blessed to have been a part of it — all of us, not just the chosen few who are lucky enough to fly it,” Ferguson said. “As a country, I think we can look back and say, ‘I remember when we flew the space shuttle and I remember the proud moment I felt when I felt the rumble in my chest when I watched the space shuttle launch, and I long for those days again.’”
