The SpaceX and the NASA are preparing to complete their most important joint mission to date. This is the Crew Dragon Demo-2, which is designed to transport humans on regular space flights from Earth to the Space Station and back.
The Demo-2 is the first manned mission launched by the United States after the last Space Shuttle mission in 2011. The The first attempt to launch the Crew Dragon Demo-2 was for May 27, but was canceled due to bad weather, caused by a tropical storm, 16 minutes and 53 seconds before launch. The second launch attempt was made on May 30, 2020 and was successful.
The spacecraft is now preparing to return from the space station and its astronauts NASA have already boarded the Crew Dragon. The descent will take many hours and is expected to be completed late Sunday, at 21:48 Greek time, when they will fall into the Atlantic Ocean off the coast of Florida.
Astronauts Behnken and Hurley will return to Earth in a capsule and that is why they disconnected from the International Space Station early Sunday morning, at 02:00 on the morning of August 2, Greek time. The Crew capsule Dragon will do all the required maneuvers in a fully automated way, as it is designed to do.
The capsule Demo-2 along with astronauts Behnken and Hurley is scheduled to land in the Gulf of Mexico at 9:48 p.m. Greek time, where it will be approached and received by its people SpaceX. This will be the first flight for a non-governmental, commercial spacecraft.
Just the Crew Dragon enters the atmosphere, will develop its parachutes, which will slow it down to a speed of about 24 kilometers per hour. The reason it takes such a long journey from the time of departure to the time of landing is that the boat has to slow down from the starting speed estimated at around 28.160 km / h, the speed it has when departing from the ISS.
