Replace July 31, 1:12 p.m. EDT: Cumulus clouds triggered a scrub of the mission. Groups are concentrating on no sooner than Aug. 1, 2025, for the following launch try, climate allowing.
A gaggle of astronauts and a cosmonaut initially slated to fly on different missions lastly acquired their ticket to trip, however should wait a minimum of one other day earlier than attending to launch. The quartet, led by NASA astronaut Zena Cardman, will head to the Worldwide Area Station starting with a launch from Florida.
The SpaceX Crew-11 mission was somewhat greater than a minute away from the deliberate launch onboard the Crew Dragon Endeavour spacecraft when cumulus clouds popped up in simply the proper spot to set off a scrub. Groups at the moment are concentrating on liftoff from Launch Complicated 39A at NASA’s Kennedy Area Heart no sooner than Friday, Aug. 1, at 11:43 a.m. EDT (1543 UTC).
Spaceflight Now may have dwell protection starting about 4 hours previous to liftoff.
On Wednesday, the forty fifth Climate Squadron forecast a 90 % probability for favorable climate at launch. Meteorologists mentioned there was a low likelihood for interference from cumulus clouds, however that proved to be sufficient to stymie a launch try.
“The abort climate additionally seems to be very favorable [on Thursday] as nicely, with winds and waves all alongside the ascent observe being inside limits,” mentioned Steve Stich, NASA’s Industrial Crew Program supervisor, throughout a prelaunch briefing on Wednesday. “We’ll watch showers or thunderstorms, potential forecast within the staging space. We’ll watch that very rigorously.”
Wanting forward, launch climate officers mentioned on Wednesday that climate within the backup launch makes an attempt appeared worse than Thursday.
“A entrance pushing into the Southeast U.S. by the weekend is more likely to deliver elevated moisture to the native space, with a barely greater menace for a Cumulus Cloud Rule violation on Saturday,” meteorologists wrote. “Extra notably, this similar entrance will deliver a considerably greater menace for showers and storms, in addition to greater winds, alongside the ascent hall Friday and particularly Saturday.”
SpaceX will use the Falcon 9 first stage booster with the tail quantity B1094 to launch this mission. It beforehand flew on Starlink 12-10 on April 29 and Axiom Mission 4 (Ax-4) on June 25.
The booster skilled a liquid oxygen leak in the course of the touchdown on the droneship, ‘A Shortfall of Gravitas,’ in the course of the Starlink 12-10 mission, which reappeared throughout prelaunch testing on Ax-4.
The check marketing campaign forward of Crew-11 didn’t present one other leak, however Stich mentioned following the static hearth check on Tuesday (initially scheduled for Monday, however scrubbed attributable to a sensor situation on the strongback), SpaceX changed one of many engine controllers on B1094’s engine 5.
“It had some anomalous signatures and so we’ve changed that,” Stich mentioned. “We’ve checked that out and it’s good for flight.”
Rather less than eight minutes after liftoff, B1094 will goal a landing at Touchdown Zone 1 (LZ-1) at Cape Canaveral Area Power Station. This would be the 53rd touchdown at LZ-1, if all goes nicely, and in keeping with William Gerstenmaier, SpaceX’s vice chairman of Construct and Flight Reliability, that is additionally the deliberate final SpaceX use of LZ-1.
The U.S. Area Power is requiring launch suppliers who need to use touchdown pads to have them situated on the launch advanced the place the rocket departs. Gerstenmaier mentioned they may proceed use of LZ-2 following the retirement of LZ-1.
The 2 touchdown pads are situated at Launch Complicated 13, the long run dwelling of Vaya Area and Phantom Area for his or her small, orbital class rockets.
SpaceX upgrades
The Crew-11 mission would be the sixth flight for the Crew Dragon Endeavour, which first flew on the Demo-2 mission in Could 2020. NASA and SpaceX carried out thorough evaluations of the assorted subsystems on the car, since that is the primary to make a sixth flight.
When Dragon was licensed for long-duration missions as a part of the Industrial Crew Program, it was cleared for as much as 5 flights. In the end, NASA and SpaceX need to clear the spacecraft for as much as 15 flights.

SpaceX launched its fifth and last Crew Dragon car, named Grace, on the Ax-4 mission.
Amongst among the more moderen modifications made to Dragon are the enhancements made to the car’s warmth protect and to its parachute deployment system. Each had been placed on show in the course of the return of Ax-4 from the ISS.
Gerstenmaier mentioned that the Crew-11 pilot, NASA astronaut Mike Fincke, would even be sporting and upgraded intra-vehicular exercise (IVA) flight swimsuit. He mentioned it featured improved mobility.
Meet the Crew
The 4 members of the Crew-11 mission share the distinctive bond that they had been all beforehand assigned to totally different missions earlier than they discovered their option to this explicit flight.
Cardman was set to fly on the Crew-9 mission as its commander, however when points arose on the Boeing CST-100 Starliner spacecraft amid its Crew Flight Take a look at, NASA opted to floor her and fellow NASA astronaut, Stephanie Wilson, to liberate two seat for use by the CFT crew.
Cardman was shortly reassigned to Crew-11, however as of Thursday, it’s unclear when Wilson could fly. This will probably be Cardman’s first journey to area.
Her pilot, Fincke, may be very aware of spaceflight, since this will probably be his fourth journey to the Worldwide Area Station and his third spacecraft that may take him there. As a pleasant, full circle second earlier than he flies on Dragon Endeavour, his final journey to area was on STS-134, which featured the Area Shuttle orbiter named Endeavour.
He too got here from one other mission: Starliner-1. He was coaching alongside NASA astronaut and Starliner-1 commander Scott Tingle together with the 2 mission specialists: Canadian Area Company astronaut Joshua Kutryk and Japan Aerospace Exploration Company (JAXA) astronaut Kimiya Yui.
Yui is now serving as a mission specialist for the Crew-11 mission. This will probably be his second journey to the ISS after beforehand launching a decade in the past on a Russian Soyuz spacecraft.
He was a part of the event crew for a JAXA cargo car known as the HTV-X, which is scheduled to launch to the area station this Fall. Yui will assist oversee its arrival and docking, equally to when the fifth HTV spacecraft arrived in 2015.
Rounding out the crew is Roscosmos cosmonaut Oleg Platonov, who’s making his first journey to area. He was coaching to be a backup crew member on a Soyuz flight when he was pulled from that mission by the medical board.
Like six different individuals earlier than him, his trip onboard a Dragon spacecraft comes on account of a seat swap settlement between NASA and Roscosmos.
These 4 astronauts and cosmonaut are set to spend a minimum of six months, and doubtlessly as much as eight months, onboard the ISS conducting dozens of science experiments.
