The Dragon spacecraft took off on March 2 and completed the 6-day exploration mission.
The capsule worked well after landing.
"Dragon 2" is a manned spacecraft that can carry 7 astronauts.
This was the first test launch of it, carrying a dummy into space and carrying about 180 kilograms of supplies.
SpaceX uses monitoring dummy models to simulate the conditions of real astronauts.

It successfully connected with the International Space Station about 400 kilometers above the Pacific Ocean north of New Zealand on Sunday on March 3 during the mission.
This launch was the first time in eight years that the United States had used a domestically produced spacecraft to go to the International Space Station.

Subsequently, a Crew Dragon spacecraft, named "Resilience", sent four astronauts to the International Space Station, and returned them to Earth after 6 moths on May 2, 2021.

During the nine years before Crew Dragon successfully carried astronauts to the International Space Station, American astronauts took Russian Soyuz spacecraft to and from it.
ROSKOSMOS, the Russian space center charges the United States high fees.
Crew Dragon spacecraft now can carry astronauts to the International Space Station.
In subsequent missions, Russian astronauts will also take this new spacecraft.
In addition, SpaceX also plans to carry astronauts from private companies and even tourists to space.
