Commander Mike Hopkins and his three crewmates will board their Crew Dragon “Resilience” capsule Monday for a first-time maneuver to relocate the SpaceX-owned spaceship to a brand new docking port exterior the Worldwide Area Station.
Hopkins and pilot Victor Glover might be flanked by Japanese astronaut Soichi Noguchi and NASA mission specialist Shannon Walker for the 45-minute maneuver to reposition the Crew Dragon spacecraft. They are going to be suited of their white SpaceX-made stress clothes, similar to another docking or undocking on the house station.
The docking port swap Monday would be the first time a SpaceX crew capsule has carried out a relocation maneuver.
“We’re very enthusiastic about it,” Hopkins mentioned Friday.
Russian Soyuz spacecraft have modified docking ports on the Worldwide Area Station 19 instances, most lately on March 19.
“There’s a large distinction between how Soyuz does it and we do it,” Hopkins instructed Spaceflight Now in an interview final 12 months. “Soyuz does all of it manually, and that is deliberate to be automated. Nonetheless, we do have a functionality to take over and do it manually if we would have liked to.”
Hopkins’s crew launched Nov. 15 aboard the Crew Dragon spacecraft, which they named Resilience, from NASA’s Kennedy Area Middle in Florida, kicking off the primary totally operational flight of a SpaceX crew capsule. Their mission, often called Crew-1, docked with the Worldwide Area Station the following day.
The Crew Dragon Resilience glided in to a easy docking with the ahead port of the house station’s Concord module, the identical location as soon as utilized by visiting house shuttles. The relocation maneuver Monday will park the Crew Dragon Resilience spacecraft at an equivalent docking port on the highest, or zenith aspect, of the Concord module.
Floor controllers at SpaceX headquarters in Hawthorne, California, deliberate to activate and take a look at techniques on the Crew Dragon capsule Sunday.
“Sunday’s going to be actually busy earlier than we do the port relocate,” mentioned Steve Stich, NASA’s industrial crew program supervisor. “We’ll wake Dragon up. It’s been largely quiescent for these four-and-a-half months (since docking).”
On the 141st day of their mission, Hopkins, Glover, Noguchi, and Walker will float into their spaceship early Monday and shut hatches between the Crew Dragon and the house station.
The Crew Dragon Resilience spacecraft is scheduled to undock from the house station at 6:30 a.m. EDT (1030 GMT). A couple of minutes earlier than the capsule detaches from the station, an automatic command will start the method of disconnecting energy umbilicals and opening hooks to allow the Crew Dragon to depart the docking port.
“What’s fascinating about it’s it’s actually a mix of actually 4 completely different flight phases that we now have with the automobile. So there’s the usual undocking, which we’ll undergo all the identical steps — we’ll be suited — the entire identical checks that we might on the traditional day of undocking,” Hopkins mentioned. “We simply set a flag that tells the automobile that that is going to be a relocate versus a traditional undocking.”
The capsule will again away to a distance of about 200 ft, or 60 meters, based on Stich, and use its Draco thrusters to fly from a place in entrance of the house station to a location above the complicated.
“Then there’s a part after that undocking the place … the relative navigation techniques should reacquire, and in order that’s a important part,” he mentioned. “As soon as that’s finished, we’re then in a position to arrange for that port relocation piece. After which as soon as we command the port relocation piece to start out, you go from that ahead docking axis to the zenith docking axis. At that time, it’s like a traditional docking yet again.”
The Crew Dragon’s computer systems will information the capsule to an automatic link-up with the zenith port on the Concord module at 7:15 a.m. EDT (1115 GMT).
Identical to Soyuz crews who head out for a relocation maneuver, the Dragon astronauts might be ready to return again to Earth in case of issues reconnecting with the house station.
“On this very quick time period, we now have three or 4 completely different phases of flight which are occurring and nonetheless you could have that potential that if one thing goes flawed on the docking try, you would possibly find yourself coming residence,” Hopkins mentioned. “So we now have to be ready to return residence as nicely.
“So it’s a really fascinating piece of the flight, and we’re very excited that we get the chance to do this as a result of I feel it’ll be difficult, however I feel it’ll be an important functionality so as to add, significantly with the variety of various kinds of automobiles that we now have arising within the close to future,” Hopkins instructed Spaceflight Now.
NASA astronaut Kate Rubins, who was aboard the Soyuz MS-17 spacecraft when it swapped docking ports final month, mentioned the relocation is “not only a pleasure journey.”
“It’s the entire enjoyable and the work of undock day, plus the entire enjoyable and the work of docking day,” Rubins mentioned, talking from current expertise. “It’s plenty of exercise. But it surely’s fairly cool, and it’s fairly a tremendous view to separate out of your automobile that’s been your own home for months and to have the ability to take a look at it from 60 meters.”
The relocation Monday will clear the way in which for the following SpaceX crew mission to dock with the ahead place on the Concord module. SpaceX’s Crew-2 mission mission, set for launch April 22 from the Kennedy Area Middle, will carry commander Shane Kimbrough, pilot Megan McArthur, Japanese astronaut Akihiko Hoshide, and European Area Company astronaut Thomas Pesquet.
Hopkins and his crewmates are scheduled to finish their mission April 28 with a departure from the house station and a fiery re-entry again into Earth’s ambiance, culminating in a parachute-assisted splashdown off the coast of Florida.
Their undocking April 28 will then clear the highest port on the Concord module for the arrival of the following SpaceX Dragon cargo mission scheduled for launch June 3. NASA needs the Dragon cargo ship to dock with Concord’s zenith port, throughout the attain of the house station’s Canadian-built robotic arm, which is able to extract a brand new pair of photo voltaic arrays from the Dragon’s trunk to improve the orbiting lab’s energy system.
“We’ve acquired some fairly large milestones arising, so let’s not take our foot of the gasoline and ensure we’re maintaining our eye on the ball,” Hopkins mentioned Friday.
