【】Today, NASA moved another inch closer.

Since the end of NASA's space shuttle program in 2011, the American space agency has relied on Russian rockets and capsules to bring their astronauts to the International Space Station.。

This plan, of course, was never ideal, and it was never meant to be permanent. 。

Even before the end of the shuttle program, NASA got to work to find a replacement. The agency landed on the Commercial Crew program, which would see Boeing and SpaceX build new vehicles that could deliver astronauts to the space station.

Since 2010, that program has inched along, moving ever-closer to crewed and uncrewed test flights.。

Today, NASA moved another inch closer.。

On Friday, NASA announced the astronauts that will fly on the first flights of the Boeing CST-100 Starliner and SpaceX's crewed Dragon capsule. 。

“This accomplished group of American astronauts, flying on new spacecraft developed by our commercial partners Boeing and SpaceX, will launch a new era of human spaceflight," NASA administrator Jim Bridenstine said in a statement.。

All the excitement around this announcement needs to be somewhat tempered, however. 。

The Commercial Crew program, on the whole, has experienced numerous delays and budget shortfalls as Boeing and SpaceX work to bring crewed launches back to the U.S.。

Recent delays have pushed back the first flights of the Starliner and crewed Dragon to 2019, with uncrewed test flights hopefully happening in November for SpaceX or late this year, early next year for Boeing. 。

That said, astronauts, on the whole, are a charming bunch with a whole lot of personality. In light of that, watching them train and then fly these missions over the next year or so should be fun for all involved.

Here's the group that should lead the human charge back to space from the U.S., with some fun facts from NASA: 。Here's the group that should lead the human charge back to space from the U.S., with some fun facts from NASA:。

Boeing's first crewed test: mid-2019。Eric Boe。: Like many astronauts, Boe became an astronaut after a stint as an Air Force fighter pilot. He has flown to space twice before this, both on space shuttle missions. He was chosen as an astronaut in 2000.
