Why do we need to go to Mars? How many pictures of galaxies do we need?
By Mike Wall, Space. And the orbiter fleet never flew more than nine missions in a single year. The shuttle program is drawing to a close, with its last-ever mission — the STS flight of Atlantis — slated to launch Friday July 8.
So now is as good a time as any to ask: Was it worth it? Or, put another way: Astronaut Paolo Nespoli snapped this view and others during the first-ever photo session of a shuttle docked at the space station.
NASA Trapped in low-Earth orbit A chief criticism of the shuttle program is that it prevented more ambitious manned exploration missions. There is merit to that argument, experts say. Kennedy and the Race to the Moon" Palgrave Macmillan, Not enough money for Mars? Rather, the vehicle was viewed as a piece of infrastructure to enable more ambitious exploration down the road, Launius said.
Back inthe space agency presented President Richard Nixon with several proposals for its post-Apollo direction.
All of them advocated an integrated program aimed at getting astronauts to Mars in a series of steps.
Those steps involved building a shuttle and a space station, then using the station as a jumping-off point for return trips to the moon and, eventually, manned missions to Mars.
But Nixon thought all of the proposals were too expensive, so he green-lighted just one aspect of them: Top Milestones of Human Spaceflight ] As a result, there was not enough money to do these things, either. For example, the shuttle has lofted many important pieces of hardware into space, such as the Hubble Space Telescope.
And shuttle missions repaired and upgraded Hubble multiple times, enabling scientists to see the universe as never before. And hundreds of experiments performed aboard the shuttles themselves have provided scientists with new insights in a range of fields, from biology and medicine to physics and materials science.
In addition to those achievements, the shuttle program has helped humanity establish a foothold beyond our home planet for the first time — a major milestone, some analysts contend.
That probably depends on your priorities and your point of view. Some people may always view the shuttle as a costly distraction, a diversion from more ambitious goals that the nation is just now starting to work toward once again. Others will regard it as a ringing success, a triumph of American technological know-how that opened space up and fostered international cooperation like nothing ever had before.
It will likely fall somewhere in between, experts say. People "will view it with mixed feelings," he said.
