Elon Musk’s space company is set to launch the Crew-3 mission for NASA on Wednesday evening, in the fifth SpaceX crewed mission in the past eighteen months.
Crew-3 will liftoff from Launchpad 39A NASA Kennedy Space Center, Florida at 9:03 pm. ET. The astronauts will arrive at the International Space Station (ISS) on Thursday, 7:10 PM. ET
SpaceX vice-president William Gerstenmaier said to reporters at a prelaunch briefing that “everything looks good.”
SpaceX is SpaceX’s third and final operational crew launch. It was also the first Crew Dragon capsule launch that NASA has made. Crew-3 astronauts christened the Crew-3 mission “Endurance” as the Crew-3’s latest addition. The Crew-3 mission will bring the number of astronauts SpaceX has launched to 18.
SpaceX and NASA delayed the Crew-3 launch quite a bit since Oct. 30, due to weather problems in the Atlantic Ocean and minor medical concerns with one of its crew members. In order to avoid the capsule flipping down during flight, it is important that the sea be calm near the launch site. NASA refused to provide further details, citing astronaut privacy. However, it stated that this was not an emergency, and had nothing to do with the Covid-19 virus.

Crew-3 will transport four astronauts: three American and one German astronauts. They are Raja Chari (NASA), Tom Marshburn and Kayla Barron. The European Space Agency astronaut Matthias Maurer.
NASA chose Chari to be the commander of the spacecraft. Chari will fly his first spaceflight. NASA also selected Chari as an astronaut eligible to participate in future Artemis moon missions. Chari is an Air Force colonel with more than 2500 hours of flight experience.
NASA chose Marshburn as its astronaut in 2004. Marshburn has flown on this third spaceflight since he was a Space Shuttle pilot and Russian Soyuz astronaut. Marshburn used to be a NASA flight surgeon.
Barron, who was selected by NASA 2017 as a Crew-3 specialist in spaceflights, will be flying. Like Chari, the launch is Barron’s first spaceflight – she graduated from the U.S. Naval Academy, and holds a Master’s Degree in Nuclear Engineering from the University of Cambridge.
Maurer is the latest international spaceflighter to join SpaceX. He joined the European astronaut corps back in 2015. He will also be making his first space flight.
Crew Dragon ‘Endurance’ is the spacecraft

SpaceX
SpaceX was responsible for developing its Crew Dragon spacecraft as well as fine-tuning its Falcon 9 rocket in NASA’s Commercial Crew program. NASA provided SpaceX with $3.1B to launch six missions and develop the Falcon 9 rocket.
Commercial Crew is a competitive program, as NASA also awarded Boeing with $4.8 billion in contracts to develop its Starliner spacecraft — but that competing capsule remains in development due to an uncrewed flight test in December 2019These people faced many challenges.
Crew-3, the third of the six SpaceX missions, is NASA’s latest investment in spacecraft development.
NASA stresses the fact that SpaceX, along with the U.S. being able to send astronauts to orbit, also offers NASA a means to do so. cost-saving option as well. Crew Dragon will cost $55 million to send an astronaut, while the Russians would require $86 million to fly. NASA estimated last year that two private companies could compete for contract contracts. saved the agency between $20 billion and $30 billion in development costs.
A full rehearsal was held by the company for Crew-3. In October, the astronauts dressed up as the crew and drove to the launchpad wearing their suits. Tesla Model Xs that SpaceX uses for crew transportation.
The new Crew Dragon capsule Endurance will be flying this mission. SpaceX plans to fly a fourth Crew Dragon in the early part of next year. SpaceX has previously flown capsules “Resilience”, “Endeavour,” and others.
Crew Dragon is an evolution of Cargo Dragon, the company’s spacecraft. Crew Dragon is the private first spacecraft designed to transport supplies to the International Space Station (ISS) just like Cargo Dragon.
Crew Dragon can carry up to seven people to space, while SpaceX currently only allows four passengers per mission.
SpaceX recently has had incidents with the toilet onboard its Crew Dragon spacecraft, as a hose came unglued in “Resilience” during the Inspiration4 mission – although the crew onboard did not notice the problem during the spaceflight – and the “Endeavour” capsule that returned the Crew-2 mission earlier this week had a similar problem. According to SpaceX, it changed the waste management system of Endurance before Crew-3 launched in order to address the problem.
Crew Dragon’s parachutes also presented a concern as Crew Dragon’s main parachutes deployed slower than others during Crew-2’s return. Gerstenmaier told reporters that despite the slow opening, the parachute performed as expected – emphasizing that Crew Dragon can splashdown under three parachutes if needed. After recovering the Crew-2 parachutes for water, NASA and SpaceX team members examined the data and Gerstenmaier stated that there was nothing unusual after their review.
Crew Dragon capsules are expected to be used again, just as they were with Inspiration4 or Crew-2.
Falcon 9 is the rocket

Crew Dragon will be launched on SpaceX’s Falcon 9 rocket. The booster, the large section at the bottom of the rocket, is expected to land on SpaceX’s barge autonomous in the Atlantic Ocean.
SpaceX conducted a static fire on its rocket Oct. 28. Its nine engines were ignited while it stood on the launchpad.
SpaceX’s Falcon 9 rocket has been the backbone of their growing fleet. This rocket is nearly 230ft tall and has the ability to launch 25 tonnes into low earth orbit. SpaceX is pushing the boundaries of reuseability by launching satellites, while Falcon 9 can fly 10 flights.
Launch Plan
At sunset, the SpaceX Falcon 9 rocket is seen with its Crew Dragon spacecraft aboard. Preparations continue for Crew-3, which will take place at NASA’s Kennedy Space Center in Florida on Wednesday, October 27, 2021.

They will be ready to go four hours before liftoff. About a half an hour later, the crew will walk out to their Model X rides, complete with NASA logos, which will drive from the astronaut quarters out to the launchpad.
With 2½ hours to go, the astronauts will strap into their seats in Crew Dragon and begin checking that all systems are good to go. With just two hours remaining before launch, the hatch will close to the spacecraft.
SpaceX will start filling the rocket’s fuel tank 35 minutes prior to launch. This will trigger a series of final checks and processes.
A few minutes after liftoff, the Falcon 9′s booster stage will return and attempt to land on the company’s barge stationed in the Atlantic Ocean.
If anything were to go wrong in the last half hour before the launch or even during the launch, Crew Dragon will abort and fire its emergency escape system. Company tested that system SpaceX was the only one in the spacecraft. SpaceX demonstrated that the system could be activated at any moment during the intense launch phase.
Crew-3, which will spend approximately six months aboard the ISS after arriving, will complete a full-length mission.
