The heart and blood change in space, too. When we stand up on Earth, blood goes to our legs. The heart has to work extra hard against gravity to move the blood all around the body. In space, without the pull of gravity, the blood moves to the upper body and head. Mar 04, †Ј On Earth, flames rise. In space, they move outward from their source in all directions.

Subscriber Account active since. The company's Crew Dragon spaceship is the first and only commercial vehicle to carry astronauts into space. It's now a routine part of NASA's human spaceflight program. Friday's mission, called Crew-2, is the second of six crewed space-station flights that the agency has contracted from SpaceX.

NASA officials gave SpaceX the green light for launch on Tuesday after two in-depth reviews of the rocket, spaceship, and launch preparations. So we check. We check under every rock and we double check and triple check. The spaceship must reach orbit, dock to the International Space Station ISSand stay there for about six months while the astronauts work on the orbiting laboratory.

Then it has to bring them back safely. How to start your own fashion jewelry business day begins early for the Crew-2 astronauts, who will don their SpaceX spacesuits around 2 a. Then they'll say goodbye to their families, climb into a pair of custom Teslas, and drive out to Launch Complex 39A.

Early Friday, the Crew-2 astronauts will ascend the launch tower and climb aboard the Crew Dragon capsule, named Endeavour. McArthur's husband, Bob Behnken, piloted the first crewed SpaceX flight in that same capsule last year. So that is kind of a fun thing that we can share, you know, I can tease him and say, 'Hey, Can you hand over the keys? I'm ready now to go,'" McArthur recently said in a press call.

Thirty-five minutes before liftoff, at a. ET, technicians what was i thinking about begin remotely loading the Falcon 9 rocket with kerosene and cryogenically chilled liquid-oxygen propellant.

The rocket booster that will push Crew-2 into space has also been recycled. It's the same one that launched the Crew-1 mission in November. When the countdown clock hits zero Ч precisely two seconds after a.

ET Ч the Falcon 9 engines will roar to life, heaving the rocket past the launchpad. The astronauts will be pressed into their seats for about 10 minutes as the vehicle screams toward space. Then the rocket booster should fall away Ч to land back on Earth and launch another day Ч giving the Crew Dragon one final push into Earth's orbit. Liftoff is instantaneous, meaning it must occur at the precise second at which it's scheduled.

Waiting would allow the ultracold propellant to warm up, expand, and boil off Ч reducing the engines' thrust and inviting risks NASA doesn't want to take with humans on board. But for liftoff to happen, skies must be clear and winds must be low around the launch site. Friday's launch was originally scheduled for Thursday, but NASA pushed it back due to an unfavorable forecast. NASA is also monitoring weather conditions for a band of splashdown locations across the Atlantic Ocean.

If something goes wrong during launch, the Crew Dragon should automatically jettison away from the Falcon 9 rocket and parachute into the sea. So winds and waves must be gentle at those locations, and SpaceX recovery teams must be ready to speed to wherever the Endeavour capsule lands.

Once the Crew Dragon slips into orbit, it will stay there for nearly 24 hours. The astronauts will likely change out of their spacesuits, eat, get a full night's sleep, have breakfast, organize their belongings, and, eventually, put their spacesuits back on to prepare for arrival at the ISS.

The astronauts have to be suited up in case something goes wrong and the Crew Dragon has to prematurely return to Earth. The ISS will be crowded with 11 astronauts for at least four days, as the Crew-2 mission overlaps with Crew-1, the first operational SpaceX mission. That capsule, called Resilience, will then undock from the ISS, push itself toward Earth, and plummet through the atmosphere.

Parachutes should release, allowing the spaceship to drift to a splashdown off the coast of Florida. A recovery crew will be waiting to retrieve the charred Resilience capsule and carry the astronauts to shore. SpaceX, NASA, and the Coast Guard plan to secure a mile no-boat perimeter around the splashdown site in order to prevent the crowd of dangerously close onlookers that surrounded Demo-2 when that capsule landed. The Crew-2 astronauts will stay on the ISS for about six months, maintaining the station, doing repairs, and conducting scientific research.

They'll return to Earth with their own splashdown in autumn. Crew Dragon missions are the fruit of NASA's Commercial Crew Program, which the Obama administration funded in to restore the agency's human spaceflight capabilities. Their missions have restored US human spaceflight for the first time since the Space Shuttle program ended in Boeing has also developed a spaceship through the Commercial Crew Program, but it has to re-do an uncrewed test flight to the ISS before it can carry anybody into space.
