The Next Space Shuttles

The Next Space Shuttles
500 days—or thereabouts: That’s the amount of time between now and the final flight of the awesome Space Transportation System, better known to you and me as the Space Shuttle. Here’s what comes next…

It’s such a short time before the skies over Florida will no longer thunder to the sound of the Space Shuttle’s main engines under full thrust. But that doesn’t mean that after September 16, 2010, there will be any letup in the requirements to put people and hardware into orbit. What ships are in line to hop into the venerable old Shuttle’s shoes? Five, at last count, all with their own talents and differences.

Though none of these Space Shuttle replacements appears quite as glamorous or high-tech, each is special in its own way—and with any luck they could all be cheaper and more reliable in getting people and hardware into space. Orion, of course, has a historic future ahead of it, as it follows in the Apollo program’s footsteps and takes man back to the Moon.
