SpaceX’s Crew-5 astronaut mission continues to be on track to launch Wednesday (Oct. 5), although there are a number of caveats.
NASA and SpaceX groups held a launch readiness overview (LRR) at present for Crew-5, which is scheduled to raise off from Pad 39A at Florida’s Kennedy Space Center (KSC) on Wednesday at midday EDT (1600 GMT).
That continues to be the plan, for at present’s overview recognized no critical points with Crew-5’s Falcon 9 rocket, Dragon capsule or another side of the mission. Groups are nonetheless engaged on three open points, however each SpaceX and NASA expressed confidence that each one of them can be cleared up comparatively shortly.
“We had an excellent LRR,” Steve Stich, supervisor of NASA’s Industrial Crew Program, mentioned throughout a press convention this night. “We’re continuing towards launch on Wednesday.”

One of many open points entails a thrust vector management actuator for one of many 9 Merlin engines that energy the Falcon 9’s first stage. The actuator, which helps management the course of the engine’s thrust, behaved abnormally throughout a static fireplace engine take a look at that SpaceX carried out over the weekend, Stich and others mentioned throughout this night’s briefing.
The second difficulty is a communications drawback that impacts the station-keeping capacity of Just Read the Instructions, the autonomous SpaceX droneship on which the Falcon 9’s first stage will land shortly after Crew-5’s liftoff. The third difficulty is a leak with the Dragon capsule’s moveable fireplace extinguisher.
Groups are troubleshooting all three of those issues and are optimistic they will be within the rear-view mirror quickly.
“I do not see any showstoppers right here,” Benji Reed, senior director of human spaceflight packages at SpaceX, mentioned within the briefing.
SpaceX plans to interchange the misbehaving actuator on the Falcon 9 tonight, Reed mentioned, stressing that the corporate has finished such work earlier than. Groups are attempting to resolve the droneship communications difficulty remotely for the time being, he added, although SpaceX might find yourself sending individuals aboard the car as early as Tuesday (Oct. 4) to work on it if want be.
The hearth extinguisher leak, in the meantime, can be addressed by changing a wide range of parts, adopted by testing to see if the repair held.
“We truly anticipate we could have all of that finished by tomorrow morning — once more, effectively upfront of Crew-5 [liftoff],” Reed mentioned of the fireplace extinguisher work.
NASA and SpaceX identified two minor issues in the course of the Crew-5 flight readiness overview, which was held final Monday (Sept. 26).
One concerned bonds on a portion of the Dragon’s perimeter, and the opposite involved doubtlessly non-standard welds in composite overwrapped stress vessels (COPVs), bottle-like constructions which can be a part of the Falcon 9’s propulsion system.
Crew members mentioned on the time that they anticipated to clear each of these points after additional vetting and evaluation. And that apparently got here to cross, for neither drawback was talked about throughout tonight’s post-LRR briefing.
Crew-5 will ship 4 astronauts — NASA’s Nicole Mann and Josh Cassada, Japanese spaceflyer Koichi Wakata and cosmonaut Anna Kikina — to the International Space Station for a roughly five-month keep. As its title suggests, the mission is the fifth contracted crewed flight to the orbiting lab that SpaceX will fly for NASA.
Crew-5 will make historical past in a number of methods. Mann will turn into the primary Native American girl to succeed in space, for instance, and Kikina will turn into the primary Russian to fly with SpaceX.
Crew-5 was supposed get off the bottom at present, however Hurricane Ian pushed the liftoff again by two days.
The storm had a way more vital impact on the timeline for NASA’s extremely anticipated Artemis 1 moon mission. NASA had been aiming to launch the uncrewed Artemis 1 on Sept. 27, however Ian pressured the group to roll the massive rocket off KSC’s Pad 39B and again to the power’s Car Meeting Constructing.
NASA is now concentrating on Nov. 12 to Nov. 27 for the Artemis 1 liftoff. (Crew-5’s Falcon 9 and Dragon did not have to flee the pad to attend out Ian; they did not roll out to Pad 39A until Saturday, Oct. 1.)
