The four will re-enter the Earth’s atmosphere in a SpaceX Crew Dragon capsule, followed by a parachute off the coast of Florida on Saturday night. In the re-entry process, a spacecraft traveling at over 17,000 mph in the last three days will return to the Earth’s thick atmosphere, heating the exterior of the vehicle to 3,500 degrees Fahrenheit.
The capsule is then expected to deploy two sets of parachutes in succession, slowing the descent before hitting the ocean. A fleet of SpaceX rescue vessels is nearby and ready to safely carry capsules from water and its passengers.
In a Netflix documentary about the Inspiration 4 mission, Musk described the capsule passing through the re-entry as “a burning meteor.”
“That’s why it’s hard not to vaporize,” he added.
The Crew Dragon can then deploy a parachute to delay the descent, safely spray the sea, and then the rescue ship can return the four passengers to the dry land.
Despite the risks, former NASA chiefs and career safety officials said the Crew Dragon was likely to be the safest crew vehicle ever flown.
Passengers include 38-year-old billionaire Jared Isaacman, who personally funded and arranged a trip to SpaceX and its CEO Elon Musk. Haley Arseno, 29, Childhood Cancer Survivor, Assistant Doctor at St. Jude Children’s Research Hospital. Sian Procotor, 51, geologist and PhD teacher at a community college. Lockheed Martin’s 42-year-old employee and lifelong space fan, Chris Sembroski, has secured a seat in an online raffle. Isaacman has billed the mission for a St. Jude fundraiser and has so far won $ 130 million out of the $ 200 million goal.
They are not the first tourists to go into orbit, but they are called Inspiration 4 because they did not have to stay at the International Space Station under the guidance of a professional astronaut, as they did in previous missions involving space travelers. Their mission is noteworthy. Rather, the four spaceflight beginners have been riding their own 13-foot-wide capsules for the past two days at an altitude of about 350 miles (100 miles higher than where the ISS is and higher than where humans have flown). ) Spent a free flight. Decades.
The crew trained for about six months and became acquainted with each other, but did not have to undergo the rigorous NASA screening process and physical and psychological assessment that most professional astronauts do. was.
“They also need to be prepared for the worst-case scenarios where one of the crew could endanger themselves or others,” said Axios reporter Miriam Kramer, who tracked the crew during the training process. The mission mentioned in the podcast about this. “A cable tie and medicine are included in case someone needs to sedate.”
However, so far, there are no signs of problems with the crew or their vehicles.
During their stay in space, the civilians on board do a little scientific research focusing on how their bodies react to being in space, chat with their families, and “” He said he would look at a large dome-shaped window called. Listen to the music with “cupola”.
The Inspiration4 Twitter account also shared footage of Arseno talking to a patient in St. Jude, and Isaacman rang the New York Stock Exchange’s Closing Bell via satellite feed on Friday afternoon.
Other than that, there were few updates shared with the general public while the crew was on track. The first live audio or visual from within the crew capsule was shared on Friday afternoon, almost two days after its launch.
SpaceX did not respond to reporter inquiries, as it has been the company’s standard for over a year.
During the previous SpaceX Crew Dragon mission, which all flew to NASA and carried professional astronauts to the International Space Station, the general public gained more insight. The space agency and its dozens of correspondents have worked with SpaceX to share almost every moment of the journey from launch to astronaut docking on the International Space Station.
However, this mission was largely in the dark when it came to questions about the crew’s schedule and their feelings in orbit. The development of the Crew Dragon spacecraft is primarily funded by taxpayers, and SpaceX rents NASA facilities to support all of its missions, while Inspiration 4 is considered a private commercial mission. That is, companies and passengers have few requirements for transparency. After splashing on Saturday evening, the general public may not even be contacted by tourists.
There are several possible reasons why space travelers were shy about advertising while traveling. For example, the crew may not feel very good after getting on track for the first time. According to a NASA research paper, “many astronauts report symptoms of motion sickness shortly after arriving in space and shortly after returning to Earth,” and getting a restful night’s sleep in orbit is “shuttle.” It was also a serious challenge for many crew members on board the mission. ” It’s also possible for four novice space explorers to want privacy or just enjoy the experience without stopping.
However, a favorable review of their experience can be very important. SpaceX is the first of many such missions, a company that uses crew dragons to fly commercial missions with tourists and private researchers, as well as professional astronauts. I want to build a new business line.
SpaceX has already signed contracts for at least four additional NASA contract missions with five other private missions.
