In a irritating disappointment, the launch of a SpaceX Crew Dragon capsule carrying a four-man crew sure for the Worldwide House Station was known as off with simply two minutes to go due to hassle with a system used to ignite the Falcon 9’s first stage engines.
Crew-6 commander Stephen Bowen, Warren “Woody” Hoburg, cosmonaut Andrey Fedyaev and Emerati astronaut Sultan Alneyadi, the primary Arab assigned to a long-duration station flight, took the scrub in stride and patiently waited contained in the spacecraft whereas the rocket’s propellants have been drained away.
NASA says the subsequent try and launch Crew-6 can be March 2 at 12:34 a.m. EST, assuming the engine ignitor difficulty will be resolved in time. The group is passing up a potential Tuesday launch strive because of anticipated unhealthy climate.
The fluid is a chemical generally known as triethylaluminum triethylboron, or “TEA TEB.”
It was the primary last-minute launch scrub of a Crew Dragon because of a technical drawback for the reason that ferry ships began carrying astronauts to the house station in 2020, ending NASA’s sole reliance on Russian Soyuz spacecraft to take astronauts to and from the lab complicated.
Together with disappointing the crew, the last-minute scrub additionally ended an opportunity for SpaceX to launch three Falcon 9s in simply 13 hours, with afternoon launches deliberate in Florida and California to place two batches of Starlink web satellites into orbit. It wasn’t instantly recognized if these flights would stay on schedule.
However flight security is the highest precedence, and SpaceX will little question repair the ignitor difficulty after engineers have an opportunity to trace down what went flawed. The one query is how lengthy it would take.
Every time they take off, Bowen and firm can be welcomed aboard the station by Crew-5 commander Nicole Mann, Josh Cassada, Japanese astronaut Koichi Wakata and cosmonaut Anna Kikina, the primary Russian to launch aboard a Crew Dragon. They arrived on the station final October and plan to return to Earth round March 6 to shut out a 151-day mission.
Additionally welcoming the Crew-6 fliers can be Sergey Prokopyev, Dmitri Petelin and NASA astronaut Frank Rubio. They launched to the lab final September and initially deliberate to fly house in March.
However their Soyuz MS-22 ferry ship was crippled December 14 when a presumed micrometeoroid ruptured a coolant line. After an evaluation, Russian engineers concluded the spacecraft couldn’t safely be used once more due to the likelihood delicate programs might overheat.
As an alternative, a substitute Soyuz — MS-23 — was launched final Thursday, carrying gear and provides as a substitute of a crew. The spacecraft docked with the station Saturday evening, offering Prokopyev and his crewmates with a secure journey house.
However to get the crew rotation schedule again on monitor, the trio should spend an extra six months in house, coming house this fall after a full yr in orbit. They’re going to share the station with Crew 6 for many of that point.
Alneyadi, a father of six, is the second Emerati to fly in house however the first named to a full-duration six-month keep aboard the station. Throughout his expedition, two Saudi fliers will go to the lab complicated for a few week as a part of a industrial mission managed by Houston-based Axiom House.
“I believe it is going to be actually fascinating,” Alneyadi stated after arriving on the Kennedy House Heart final week. “It is for the sake of science, for the sake of spreading the information about how necessary it’s to fly (in house) and to push the boundaries of exploration, not solely within the main international locations.
“Our area can be thirsty to study extra. And I believe we can be ambassadors in these missions. Hopefully, we will come again with information and share no matter we study with all people.”
