NASA has been a part of the Commercial Crew Program where it works with companies like SpaceX to “develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the space station”. Earlier, NASA had **announced** that the upcoming  **Crew-2 mission will be leaving for the International Space Station** not earlier than 20 April. NASA astronauts Shane Kimbrough and Megan McArthur will serve as the spacecraft commander and pilot for this second mission, and JAXA astronaut Akihiko Hoshide along with ESA astronaut Thomas Pesquet will be the mission specialists.
