After finishing a gown rehearsal for launch day over the weekend, the 4 astronauts gearing up for liftoff Thursday on a SpaceX 9 rocket are in good spirits and spending time with their households in Florida earlier than leaving the planet for six months.

Forecasters with the U.S. Area Power’s 45th Climate Squadron predict an 80% likelihood of acceptable climate for launch at 6:11 a.m. EDT (1011 GMT) Thursday from pad 39A at NASA’s Kennedy Area Heart. The 4 astronauts, led by veteran NASA commander Shane Kimbrough, will fly with a Crew Dragon capsule to the Worldwide Area Station.

Kimbrough and NASA crewmate Megan McArthur, Akihiko Hoshide of Japan, and Thomas Pesquet of France — all with spaceflight expertise — suited up of their SpaceX stress clothes early Sunday and rode in Tesla Mannequin X SUVs from crew quarters at Kennedy to pad 39A. The astronauts used the identical timeline they may comply with on launch day, and departed their suit-up room on the Neil Armstrong Operations and Checkout Constructing shortly earlier than three a.m. EDT (0700 GMT).

They arrived on the launch pad lower than a half-hour later to board the Crew Dragon Endeavour spacecraft on high of the 215-foot-tall (65-meter) Falcon 9 rocket. They then disembarked after simulating a scrubbed launch try, and returned to crew quarters for a debriefing earlier than dawn Sunday.

The “dry gown rehearsal” was a follow run for the astronauts and SpaceX help groups who will assist the crew members swimsuit up and strap in to the Dragon capsule.

Pesquet, a French-born European Area Company astronaut, stated Monday every little thing was on monitor for liftoff Thursday. The mission would be the second common area station crew rotation flight by SpaceX below a multibillion-dollar contract with NASA, which additionally arranges rides to the advanced for European, Japanese, and Canadian astronauts.

“We’re placing the ending touches on the coaching,” Pesquet stated Monday morning. “There are solely … three days precisely, just a little bit much less now, to go earlier than the launch. Every part goes properly. The rocket is prepared. The spacecraft is prepared.”

“We truly had a few days of margin that we didn’t want ultimately, so now the rocket is simply going to take a seat on the launch pad at the moment and tomorrow, just about, earlier than the ultimate prep on Wednesday, after which on Thursday we’ll be able to launch,” stated Pesquet, who spent 196 days in orbit on a earlier journey to the area station. “The crew is joyful. The crew is in nice form, in excessive spirits. The households are right here on the Cape, and every little thing is ok. We’re making an attempt to get pleasure from our previous few days on earlier than leaving the planet for six months.”

The Dragon astronauts are scheduled to return to Earth for a splashdown off the coast of Florida in late October.

Hoshide will take over as commander of the area station’s Expedition 65 crew subsequent week, assuming the helm from NASA astronaut Shannon Walker. Walker and her crewmates — Mike , Victor Glover, and Japanese astronaut Soichi Noguchi — are scheduled to come back again to Earth on April 28 on their Crew Dragon Resilience spacecraft, wrapping up a mission that launched in November.

Later this 12 months, Pesquet will get a flip at area station commander. Pesquet labored as a spacecraft engineer in European trade and for the French area company, then turned an airline pilot for Air France earlier than his choice as an ESA astronaut in 2009. He first launched into area in 2016.

On his first spaceflight, Pesquet launched and landed on a Russian Soyuz capsule, which has a design rooted within the 1960s. He advised reporters Monday that he expects an analogous experience throughout launch on the Falcon 9 rocket, which burns the identical kerosene and liquid oxygen propellants as Russia’s venerable Soyuz launcher.

The Crew-2 mission is the primary time SpaceX has used a reused booster and Crew Dragon spacecraft for an astronaut mission.

“I don’t anticipate it to be unhealthy in any respect,” Pesquet stated. “Everyone who flew on the Dragon and Falcon 9 beloved it thus far. The return to Earth is all the time a bit tough, however that’s the identical in each single area car.”

He stated the automation of SpaceX’s Crew Dragon spacecraft makes the car safer. Beneath regular situations, the capsule flies to and from the area station on autopilot.

“For us, what it is we don’t have that many actions to soak up a nominal scenario,” stated Pesquet, who was an teacher in cockpit protocols for Air France. “After all, in an off-nominal scenario, now we have to take motion. However what it means is you’re obtainable to handle the scenario. Your situational consciousness is simply unbelievable.

“You may have these large massive screens which can be displaying you, in each potential approach, what’s taking place,” Pesquet stated. “The precedence of the data is already pre-analyzed by the system. The colour coding is nice. The best way the data is laid out is simply incredible. You already know on a regular basis what’s occurring.

“Soyuz is unbelievably dependable, however you needed to make sense of all that info that was sparse and disseminated at each nook of your management panel, with digital gauges and analog gauges,” Pesquet stated. “That’s why the coaching was a lot longer. I believe it’s nice. We’ll adore it, and I believe it makes the system extra dependable general.”

Whereas forecasters predict good situations on the launch website in Florida early Thursday, officers could have to watch climate downrange within the Atlantic Ocean.

There’s a “reasonable” threat of poor situations within the Falcon 9 booster’s downrange touchdown zone within the Atlantic — roughly due east of South Carolina — and a low likelihood of unfavorable higher stage winds over the launch pad. SpaceX and NASA officers will proceed evaluating downrange winds and sea states at places throughout the Atlantic Ocean to evaluate whether or not the situations are acceptable for splashdown of the Dragon capsule within the occasion of an in-flight abort.

“A moist and unstable sample will proceed over Central Florida as a frontal boundary stays stalled throughout the world,” the climate crew wrote within the forecast Monday morning. “Rain showers and remoted thunderstorms are doubtless as low stress waves transfer alongside the boundary over the subsequent two days.

“On Wednesday, excessive stress begins to construct in and push the unsettled climate south by means of the day. By Thursday morning, the excessive stress shall be centered close to Arkansas, creating gusty northerly winds alongside the Area Coast because of the stress gradient between the excessive and the departing boundary,” the foresters wrote.

“The first climate concern Thursday morning shall be these gusty liftoff winds to this sturdy stress gradient.”

At launch time Thursday, forecasters anticipate north-northeast winds of 17 to 22 mph, a temperature of about 68 levels Fahrenheit, and some low-level clouds.

There’s additionally an 80% likelihood of fine climate for a backup launch alternative at 5:49 a.m. EDT (0949 GMT) Friday.
