Why is this important?

The United States hasn’t launched its own astronauts into space since the Space Shuttle Program ended in 2011. Since then, NASA’s astronauts have had to travel to Russia and train on the country’s Soyuz spacecraft. Those seats have cost NASA as much as $86 million each.But the space agency chose not to create its own replacement for the Shuttle. Instead, it asked the private sector to develop a spacecraft capable of safely ferrying astronauts to and from the International Space Station — a controversial decision considering that NASA had never before outsourced the development of a human-rated spacecraft. The thinking was that commercial companies could drive down costs and spur innovation, and NASA would have more time and resources to focus on exploring deeper into the solar system.

Who is flying to space?

Two veteran astronauts: Robert Behnken, 49, and Douglas Hurley, 53. They work for NASA, but they’ve worked closely with SpaceX and have been trained to fly the Crew Dragon capsule, which will become only the fifth spacecraft design — after the Mercury, Gemini, Apollo, and Space Shuttle vehicles — that NASA has certified as safe enough for humans.

NASA astronauts Bob Behnken, left, and Doug Hurley have spent years learning how to operate SpaceX’s Crew Dragon capsule.Behnken and Hurley both began their careers as military test pilots and have logged hundreds of hours piloting supersonic jets. They also both flew on previous Space Shuttle missions. When NASA selected them for this mission in 2018, it continued a long lineage of military test pilots who were deemed to have the “right stuff” for groundbreaking moments in human spaceflight history.NASA wants to keep Behnken and Hurley on the space station until another Crew Dragon capsule is ready to send more people on its next mission. The astronauts told reporters last week that they’re expecting to spend one to three months in space. The maximum length is 110 days, according to NASA.
