(CNN) SpaceX and NASA are once again preparing to launch a new crew to the International Space Station after the first attempt to get astronauts off Earth was thwarted at the last moments by a clogged filter.
The mission — which will carry two NASA astronauts, a Russian cosmonaut and an astronaut from the United Arab Emirates — is now scheduled to lift off at 12:34 a.m. ET Thursday from NASA’s Kennedy Space Center in Cape Canaveral, Florida.
The Crew Dragon, the vehicle carrying the astronauts, separates from the rocket after launch and will spend about a day maneuvering in orbit before linking up with the space station. The capsule is scheduled to dock at 1:17 a.m. ET on Friday.
case left First launch attempt It was resolved Tuesday early Wednesday morning, according to an update NASA posted on its site website.
During the launch broadcast, officials reported that ground systems engineers made the decision to cancel the launch with less than three minutes on the clock. Engineers said they have discovered a problem with a material called triethylaluminum triethylboron, or TEA-TEB, which is a highly flammable liquid used to ignite the engines of the Falcon 9 rocket at liftoff.
The problem occurred during the “bleeding” process, which aims to ensure that each of the nine Falcon 9 rocket engines is supplied with an adequate amount of TEA-TEB fluid when it’s time to ignite. The problem arose when fluid migrated from a reservoir on Earth into a “catch tank,” according to NASA.
According to a NASA update, “After a thorough review of the ground-based data and system, NASA and SpaceX have determined that there was a decrease in flow to the ground-based TEA-TEB catch tank due to a clogged ground-filter.”
NASA said the clogged filter explained the aberration seen by engineers on launch day.
“The SpaceX teams replaced the filter, purged the TEA-TEB line with nitrogen, and verified that the lines are clean and ready for launch,” the post reads.
Everything about this launch
This mission will mark the seventh astronaut flight that SpaceX has flown on behalf of NASA since 2020, continuing public and private efforts to preserve the orbiting laboratory. in full.
On board the Crew-6 will include NASA astronauts Stephen Bowen, a veteran of three space shuttle missions, and First Pilot Warren “Woody” Hoburg, as well as Sultan Al Neyadi, who will be the second astronaut from the United Arab Emirates to fly. To space, Russian cosmonaut Andrei Fedyaev.
Once Bowen, Hoborg, Fedayev, and Alniadi aboard the space station, they will work to take over operations from the SpaceX Crew-5 astronauts who arrived at the space station in October 2022.
They are expected to spend up to six months aboard the orbiting laboratory, conducting science experiments and maintaining the two-decade-old station.
The mission comes as the astronauts currently on the space station are facing a separate transportation problem. In December, the Russian Soyuz spacecraft that was used to carry cosmonauts Sergey Prokopyev and Dmitry Petlin and NASA astronaut Frank Rubio to the space station developed a coolant leak. After the capsule was deemed unsafe to return cosmonauts, the Russian space agency, Roscosmos, A replacement vehicle launched on February 23rd. I got to the space station on Saturday.
Work with the Russians
Russian cosmonaut Fedyaev joined Crew-6 as part of a Ride sharing agreement It took place in 2022 between NASA and Roscosmos. The agreement aims to ensure continued access to the space station for both Roscosmos and NASA: Should a SpaceX Crew Dragon capsule or the Russian Soyuz spacecraft used to transport people there run into difficulties and decommission them, its counterpart could handle getting astronauts from both countries into orbit.
This flight will be Fedyaev’s first mission into space.
Despite the ongoing geopolitical tensions sparked by its invasion of Ukraine in February 2022, Russia remains the United States’ primary partner on the space station. NASA officials have repeatedly said that the conflict had no impact on cooperation between the two nations’ space agencies.
“Space cooperation has a very long history, and we are setting an example for how people live on Earth,” Fedyaev said during a January 24 press briefing.
Bowen, the 59-year-old NASA astronaut who will be the Crew-6 mission commander, also weighed in.
“I’ve been working and training with astronauts for over 20 years, and it’s always been amazing,” he said during the briefing. “Once you get into space, we’ll have one crew and one vehicle, and we all have the same goal.”
Bowen grew up in Cohasset, Massachusetts, and studied engineering, earning a bachelor’s degree in electrical engineering from the US Naval Academy in 1986 and a master’s degree in ocean engineering from the MIT and Woods Hole Joint Oceanography Program in 1993.
He also completed military submarine training and served in the US Navy before being selected for the NASA Astronaut Corps in 2000, becoming the first submarine officer selected by the space agency.
He previously completed three missions between 2008 and 2011, during NASA’s space shuttle program, and logged a total of more than 47 days in space.
“I just hope my body will hold the memory of 12 years ago so I can enjoy it,” Bowen said of the Crew-6 launch.
Meet the rest of Crew-6
Hoburg, who is a pilot for this mission, is a native of Pittsburgh who earned his Ph.D. in electrical engineering and computer science at the University of California, Berkeley, before becoming an assistant professor of aeronautics and astronautics at MIT. He joined the NASA astronaut team in 2017.
“We’re going to be in space for six months,” Hoburgh told reporters of his expectations for the trip. “I think back to six months ago and I think — well, that’s a long time.”
But Hoburgh added, “I’m very much looking forward to getting a look at the dome first,” referring to the well-known area on the space station that features a large window that offers panoramic views of Earth.
Al Neyadi, who served as a backup in 2019 to Hazza Ali Al Mansoori, is now set to become the first astronaut from the United Arab Emirates to travel into orbit, and the first Emirati astronaut to complete a long stay in space.
At a press conference in January, Al Neyadi said he planned to bring Middle Eastern food to share with his colleagues while he was in space. As a trained jiu-jitsu practitioner, he’ll also pack a kimono, the traditional martial arts outfit.
Al Neyadi said in A Press Conference After arriving at Kennedy Space Center on February 21 “I couldn’t ask for more from the team. I think we’re ready – physically, mentally and technically.”
What will they do in space
During their mission in space, Crew-6 astronauts will oversee more than 200 science and technology projects, including research on how certain materials burn in a microgravity environment and investigating microbial samples that will be collected from outside the space station.
The crew will host two other major missions that will stop at the space station during their stay. The first is the Boeing Crew flight test, which will mark the first astronaut mission under the Boeing-NASA partnership. Scheduled for April, the flight will bring NASA astronauts Barry Wilmore and Sunita Williams to the space station, marking the final stage of a test and demonstration program that Boeing needs to certify the Starliner spacecraft for routine astronaut missions.
Then, in May, a group of four astronauts is scheduled to arrive on Axiom Mission 2, or AX-2 for short—a privately funded spaceflight to the space station. The initiative, which will deploy a separate SpaceX Crew Dragon capsule, will have its leader Peggy Whitson, a former NASA astronaut and now a private astronaut with the Texas-based space company Axiom, who brokered and organized the mission.
It will also include three paying customers, similar to Axiom Mission 1, which visited the space station in April 2022, including astronauts from Saudi Arabia visiting the orbiting laboratory. Their seats have already been paid for Kingdom of Saudi Arabia.
Bowen said in January that the Boeing CFT mission and the AX-2 will be major stops.
“It’s another paradigm shift,” he said. “These two events — huge events — in spaceflight that happen during our hyperstimulus, plus all the other work we have to do, I don’t think we’ll be fully able to grasp until after the fact.”
