Four astronauts went to the ISS aboard Crew Dragon of SpaceX company. This is the first official mission using a capsule.
The SpaceX spacecraft with four astronauts took off from Cape Canaveral on Sunday, marking the beginning of a new era for the United States, when the country can finally use its own opportunities to work on the ISS. NASA astronauts Michael Hopkins, Victor Glover, Shannon Walker and Japanese Soichi Noguchi are now on their way to the station aboard the Crew Dragon, docking late tonight.
This means that the crew will spend 27 hours in orbit while the spacecraft slowly maneuvers to their destination. The trip would be shorter if Crew Dragon could launch on Saturday as originally planned. But the bad weather caused by Hurricane Eta forced the control center to postpone takeoff until Sunday evening.
The capsule has a working toilet, and the astronauts will have time to sleep a little, because the fully autonomous unit maneuvers in orbit under the control of experts from Earth.
This is the first fully operational SpaceX mission with the crew after Demo-1 in May, when Douglas Hurley and Robert Benken tried the capsule flight on the ISS. The Crew-1 team now plans to conduct all sorts of experiments during their six-month stay on the ISS, including a study of how microgravity affects human heart tissue.
