Behnken and Hurley have spent the past two months aboard the ISS alongside NASA astronaut Christopher Cassidy and Russian cosmonauts Anatoli Ivanishin and Ivan Vagner, who had previously flown into orbit from the laboratory aboard a Soyuz spacecraft built in Russia.
The United States is a major operator of the space station, but the country has not had the ability to launch its own astronauts to the ISS since the space shuttle program ended in 2011. Since then, NASA astronauts have had They travel to Russia and train on the country’s Soyuz spacecraft in seats that have cost up to $ 90 million each.
The journey that Behnken and Hurley started in May will not be considered a success until they return safely to Earth. And the journey home will be as dangerous as the journey in orbit.
If time permits, astronauts will board their Crew Dragon spacecraft on August 1 and spend a day slowly descending toward Earth. The next day, the capsule will traverse Earth’s thick atmosphere and deploy parachutes to cushion its landing in the Atlantic Ocean.
If done successfully, SpaceX’s Crew Dragon vehicle could be officially certified for human space flight missions. (Behnken and Hurley’s trip is considered a test flight.)
NASA’s decision to set a target return date is a sign that SpaceX is on track to have a second crew Dragon ready to fly the first manned operational mission, called Crew-1, this fall. That mission is slated to bring three NASA astronauts – Victor Glover, Michael Hopkins, Shannon Walker, and Soichi Noguchi, an astronaut from the Japan space agency, to the ISS.
