After a busy two months in house, the primary two NASA astronauts to go to the Worldwide House Station on a industrial car are prepared to return again to Earth — if the climate cooperates.
Doug Hurley and Bob Behnken arrived on the Worldwide House Station on Could 31, the day after changing into the primary astronauts to launch from Florida tucked inside a SpaceX Crew Dragon capsule. However this weekend, they need to deal with one of the crucial difficult points of the mission: leaving the house station, spending hours inside that very same capsule, parachuting by way of Earth’s ambiance and splashing down off the coast of Florida.
“It is simply time to go give it a try to see the way it goes,” Hurley stated throughout a information convention on Friday (July 31) held together with his colleagues in orbit throughout his final full day on the house station.
Hurley and Behnken are presently scheduled to climb into the Crew Dragon capsule Saturday (Aug. 1) and splash down on Sunday (Aug. 2). Their preliminary splashdown goal website is within the Gulf of Mexico off the coast of Florida’s Panama Metropolis, NASA officers have stated.

The splashdown process marks the ultimate hurdle of the duo’s mission, dubbed Demo-2, and marks the ultimate take a look at for SpaceX’s industrial crew system. After a protected return, the corporate needs to be clear to launch common missions to the orbiting laboratory.
Each step of the Demo-2 mission has been an evaluation of the new spacecraft, and each Behnken and Hurley and NASA management have emphasised all through the mission that it has been a take a look at flight. The astronauts’ job has been to vet each side of the car and guarantee it’s prepared for normal use by crewmembers, however it additionally implies that they’ve been guinea pigs of a form all through the mission, and that holds for his or her return as nicely, though the astronauts stated they’re unfazed.
“As we get nearer, I believe we actually focus an increasing number of on our preparations to be prepared for the splashdown actions,” Behnken stated. “I nonetheless do not feel nervous about it.”
For many years, U.S. astronauts coming back from house have touched down on land, both in a runway touchdown like these performed by NASA’s house shuttles or in a parachute touchdown because the Russian Soyuz capsules do. The final American crew to return to the ocean did so 45 years in the past, on the finish of the Apollo-Soyuz Test Project mission through which astronauts met up with Soviet cosmonauts in orbit.
“The water touchdown portion of it’s fairly difficult from a physiological standpoint, simply after getting back from being in microgravity for on the order of 1 to 2 months,” Hurley stated. “The bottom groups are totally conscious of the challenges of a water touchdown and what it does to the human physique and we’ll simply take it from there.”

Though NASA is raring to see the Demo-2 capsule undock, the scheduling of the return journey is not set in stone. NASA and SpaceX will base the timing of the process on a number of climate and ocean standards at whichever of the seven splashdown sites the staff finally ends up focusing on.
Proper now, these situations are wanting difficult. The Nationwide Oceanic and Atmospheric Administration’s (NOAA) Nationwide Hurricane Middle is monitoring a system referred to as Hurricane Isaias because it barrels by way of the Caribbean Sea, heading towards Florida.
As of this morning, forecasts predict the storm will head up the japanese coast of Florida all through the day on Sunday, doubtlessly leaving protected situations on the Gulf coast, the place 4 of the seven potential websites are positioned.
The astronauts stated they’re leaving climate issues to workers on the bottom and are able to do what mission management advises. “We do not management the climate and we all know we are able to keep up right here longer,” Behnken stated. “There’s extra chow and I do know the house station program’s acquired extra work that we are able to do for these [researchers] and other people which have despatched science up right here to the house station.”
A protected return for Demo-2 is the final piece of the puzzle for NASA approval of SpaceX’s subsequent crewed launch, the corporate’s first full-length mission to the house station. Dubbed Crew-1, that mission is currently targeting launch in late September.
Crew-1 will carry three NASA astronauts — Michael Hopkins, Victor Glover and Shannon Walker — and Japan’s Soichi Noguchi to the house station for a keep greater than six months lengthy that may put the orbiting laboratory’s workers rely at seven.
NASA additionally not too long ago introduced staffing for the subsequent mission, Crew-2, which can see U.S. astronauts Megan McArthur (who’s married to Behnken) and Shane Kimbrough, Japanese astronaut Akihiko Hoshide and European astronaut Thomas Pesquet blast off Earth in 2021. That mission will use the identical Endeavour Crew Dragon capsule because the Demo-2 crew.
