Through its history, Discovery has been a symbol of the enduring persistence of the shuttle mission. It was the first shuttle to return to flight after the tragic Challenger explosion, and again after Columbia disintegrated in 2003. It was the first shuttle to dock with the International Space Station, and it helped launch the Hubble Space Telescope. It’s earned its air-parade around Cape Canaveral and the US capital today. And it has earned its permanent place in history.
The Discovery is the first of the three remaining shuttles to ship off to its final resting place. Over the next year, the remaining two — Endeavour and Atlantis — will be decommissioned and sent to Canada and the Kennedy Space Center, respectively. It’s a sad — but ultimately necessary — end to a shuttle program that has outlived its practicality and, more importantly, its funding.
We’re not done with space travel entirely, of course. SpaceX, one of the private companies picking up the galactic mantle, has been approved to travel to the International Space Station on April 30. It will be the first time that any private vessel has made that trip. But the private space tourism vessels won’t be pushing boundaries any further than have already been pushed. That’s still the province of NASA.
After the Constellation debacle, we’re we’re decades away from NASA’s next manned spacecraft launch. There’s no saying what for it will take, other than that the mission will take us further than we’ve ever been, and will teach us more than we’ve ever known about space. Just like Discovery did for decades. Just like NASA’s always done. [NASA]
