CAPE CANAVERAL, Fla. — NASA has given SpaceX the official go-ahead for the launch of its subsequent crew mission to the Worldwide House Station.
That mission, known as Crew-2, will blast off on a SpaceX Falcon 9 rocket at 6:11 a.m. EST (1011 GMT) on Thursday morning (April 22) from NASA’s historic Pad 39A and Kennedy House Middle in Florida. Will probably be the second flight of this specific Crew Dragon. The capsule, named “Endeavour,” first carried NASA astronauts Bob Behnken and Doug Hurley to and from the area station final 12 months for the Demo-2 check flight.
It can even be the second flight for the primary stage booster, which beforehand ferried the Crew-1 astronauts to the area station on Nov. 18, 2020. Strapped contained in the Dragon will likely be 4 veteran crewmembers: NASA astronauts Shane Kimbrough and Megan McArthur, European House Company (ESA) astronaut Thomas Pesquet and Japan Aerospace Exploration Company (JAXA) astronaut Akihiko Hoshide.

SpaceX’s Crew Dragon marks the third completely different area car for each Hoshide and Kimbrough, because the duo adopted within the footsteps of Crew-1 astronaut Soichi Noguchi of JAXA. (Noguchi turned the primary astronaut to fly in three completely different spacecraft — the area shuttle, the Soyuz, and now the Crew Dragon — when he launched in November 2020.)
Final week, NASA and SpaceX met for a flight readiness evaluation to go over the spacecraft and launch car to make sure each had been licensed and able to fly later this week. The groups went by means of their checklists and solely left one minor subject to work by means of previous to liftoff.
A type of points was regarding how a lot liquid oxygen is loaded onto the launch car. Falcon 9 depends on two parts to gasoline its journeys to area: rocket-grade liquid kerosene and liquid oxygen.
In keeping with Invoice Gerstenmaier, present vp of construct and flight reliability at SpaceX (and former head of human spaceflight at NASA), mentioned in a information convention final Thursday (April 15) that the groups detected a small discrepancy within the quantity of liquid oxygen loaded into the launcher in comparison with the quantity SpaceX had anticipated.
On Tuesday (April 20), Benji Reed, senior director of human spaceflight at SpaceX, mentioned that the liquid oxygen subject had been resolved and that Falcon and Dragon handed two massive exams over the weekend: a static fireplace check and a costume rehearsal with the crew. Each workouts had been executed flawlessly and the mission acquired the inexperienced gentle to proceed with Thursday’s early morning liftoff.
“It is a very thrilling time, and we’re wanting ahead to a profitable mission,” Reed mentioned throughout a prelaunch information convention on Tuesday (April 20).
Eye on the sky
Forecasters on the 45th House Wing’s Climate Squadron are calling for an 80% favorable chance of liftoff within the predawn hours on Thursday. The one trigger for concern on the launch web site are liftoff winds. It has been very wet right here on the area coast within the days main as much as launch, however luckily a excessive strain system will likely be shifting in on Wednesday, and that ought to filter the storms, climate officer Brian Cisek mentioned in Tuesday’s information convention.
The staff on the 45th House Wing displays a set of 10 climate constraints on launch day, plus any further constraints set by the precise launch supplier. These embody electrical discipline guidelines, thick cloud guidelines, and the potential for cumulus clouds, to call a couple of. However SpaceX additionally has its personal set of constraints that cope with how a lot precipitation the rocket can fly by means of and issues like upper-level winds.
However that is not all. SpaceX additionally has to observe ocean situations on the touchdown zone to ensure that the booster can safely land on the drone ship. If that wasn’t advanced sufficient, as a result of there are astronauts on board this Dragon, NASA has its personal situations that consider the climate at numerous abort factors all through Dragon’s climb to orbit.

Crew Dragon is outfitted with a launch escape system that may push the spacecraft to security within the unlikely occasion that one thing goes actually mistaken with the rocket because it’s climbing towards area. All of those components collectively make up the launch climate constraints for this and different business crew missions.
If all goes as deliberate, and the climate continues to look good, then we are able to search for a predawn liftoff on Thursday morning. Cisek says there’s a backup alternative on Friday morning and the climate seems equally as promising for it.
