THE LAUNCH OF SPACEX FIRST CREWED SPACEFLIGHT

The first SpaceX Crew Dragon spacecraft to carry astronauts successfully docked with the International Space Station on, May 31, at 10:16 a.m. EDT (1416 GMT) after being delayed for the bad weather condition.


DEMO-2 MISSION

Demo-2 is the final major test for SpaceX's human spaceflight system to be certified by NASA for operational crew missions to and from the International Space Station. SpaceX is returning human spaceflight to the United States with one of the safest, most advanced systems ever built, and NASA's Commercial Crew Program is a turning point for America's future in space exploration that lays the groundwork for future missions to the Moon, Mars, and beyond.


WHO ARE THE ASTRONAUTS?

Surprisingly, Crew Dragon has two commanders.



The crew for Demo-2 is veteran NASA astronauts Bob Behnken and Doug Hurley.


Behnken will serve as the mission's joint operations commander while Hurley is a Crew Dragon spacecraft commander. Both men have flown to space multiple times.


HOW DOES IT GET TO THE INTERNATIONAL SPACE STATION?

On Demo-2, SpaceX's Crew Dragon took about 19 hours to reach the International Space Station.


It took Crew Dragon about 12 minutes to reach its initial orbit. The first stage of its Falcon 9 rocket returned to Earth to land on a drone ship for future reuse.


Crew Dragon spent a dozen or so hours chasing the space station, gradually raising its orbit to the 250-mile (400 kilometers) altitude of the International Space Station.


While Crew Dragon is designed to dock itself autonomously, Hurley will take manual command of the spacecraft during the rendezvous to test the vehicle's flight systems.

HOW LONG IS THE FLIGHT?

The date was not mentioned, But the mission will last at least one month, and possibly up to four months. The exact duration will depend on a few factors.


The duration will depend on Demo-2's follow-up mission called Crew-1, which will be SpaceX's first operational mission to the space station for NASA. The Crew-1 Dragon spacecraft is being built now. It will launch four astronauts to the space station later this year.
