All about the ancient tribes
Shortly before the final deorbit burn, Crew Dragon will separate from its trunk, which will burn up in Earth’s atmosphere. The spacecraft then executes the deorbit burn, which commits Crew Dragon to return and places it on an orbit with the proper trajectory for splashdown.
— — NASA’s new era of privately funded spacecraft to make deliveries to the International Space Station made a splash Thursday when the SpaceX Dragon capsule successfully came down in the Pacific Ocean.
The operational Crew Dragon spacecraft will be capable of staying in orbit for at least 210 days as a NASA requirement. Upon conclusion of the mission, Crew Dragon will autonomously undock with the two astronauts on board, depart the space station and re-enter the Earth’s atmosphere.
Water landings tend to be a bit pricier and make crew recovery more difficult. The salt water can also be rough on the vehicle’s electrical components and make the spacecraft more difficult to reuse. But, the water offers a bit more cushion for landing.
In space, astronauts lose fluid volume—including up to 22% of their blood volume. Because it has less blood to pump, the heart will atrophy. Upon return to earth, the blood begins to pool in the lower extremities again, resulting in orthostatic hypotension.”
They don’t. SpaceX is a for-profit company, whereas NASA is a taxpayer-funded entity free to pursue scientific discoveries that are not directly linked to financial gain.
The SpaceX Dragon Capsule carrying Doug Hurley and Bob Behnken came down in the Gulf of Mexico just south of Pensacola on Florida’s Gulf coast. Hurley’s and Behnken’s capsule hit the water at about 14:48 EDT (19:48 BST; 18:48 GMT).
Endeavour will be refurbished and reused for the SpaceX Crew-2 mission, expected to launch on 30 March 2021. Crew Dragon Demo-2.

As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
NASA astronaut Scott Kelly completed a single mission aboard the International Space Station of 340 days on March 1, 2016. NASA astronaut Christina Koch’s first mission aboard the orbiting lab ended after 328 days on Feb.
Mission Objectives The Crew Dragon spacecraft is capable of staying in orbit for at least 210 days, as a NASA requirement.
Veteran NASA astronauts Bob Behnken and Doug Hurley will launch on this historic mission from NASA’s Kennedy Space Center. But they won’t arrive at the space station until the next day (May 28), so it’s important that there’s a toilet on board.
NASA has agreed to allow its astronauts to fly on reused Crew Dragon spaceships and Falcon 9 boosters beginning as soon as SpaceX’s third launch of a crew to the International Space Station, a mission expected to launch next year.
