KokoYo- chinarainbow.org Jared Isaacman will return to space on three flights with SpaceX. The billionaire will this time plan to reach a higher orbit than his first flight.
The private mission will fly from NASA’s Kennedy Space Center. Isaacman, as mission commander, will join longtime colleague Scott Poteet as a pilot. Two SpaceX employees, Sarah Gillis and Anna Menon, the company’s chief space operations engineer, completed the crew. Gillis oversaw the astronaut training program and Menon managed the development of his crew’s operations.
The first mission in the so-called Polaris Program is set to launch a four-man crew led by Isaacman in the fourth quarter on the company’s Falcon 9 rocket and Crew Dragon spacecraft.
According to the program’s website, the inaugural flight, Polaris Dawn, will be the first of three missions, with the latter being the first crewed space flight of SpaceX’s Starship rocket.
“The Polaris program is an important step in advancing human space exploration while helping to solve problems through the use of innovative technologies on Earth,” Isaacman said in a statement.
The Polaris Dawn mission will spend up to five days in orbit. It is thought to travel to the Van Allen radiation belt, having an inner band stretching from about 400 to 6,000 miles above Earth, in part to help the crew research how radiation in space affects the human body.
Radiation remains a serious concern for space flights to the Moon and Mars, as SpaceX says, because they would require prolonged radiation exposure, which could lead to an increased risk of cancer and degenerative diseases and other long-term impacts.
Isaacman was lucky this time, he was the first one planned to try new technology.
Isaacman was lucky this time, he was the first one planned to try new technology. Those technologies include spacewalking outfits still in the works, then the first flights with new people from Starship, aimed at trips to the Moon and Mars, testing Starlink satellite communications in space and conducting scientific research on human health.
