Usa: a billionaire will lead three more missions in space
20 March 2022
Jared Isaacman is a young entrepreneur who chartered the first human space flight last year, the Inspiration4 mission, which completed three days orbital on a Space X Dragon for Jude children’s Hospital research. Jared announced three more future missions in collaboration with Space X. He founded it with a crew, having SpaceX engineer Sarah Gilles, Anna Menon(Medical officer), and Scott Poteet (Pilot). The three missions are the first commercial spacewalk, the first crewed flight of the next-generation Starship rocket, and experimenting on space for some effects of radiations. The first mission is Polaris Dawn, which will occur at the end of this year. It is so designed to support long-duration spaceflight capabilities humans ever had. It aims to explore the newest technologies to go deep in space than Moon, Mars.
The Polaris will attempt to fly deep, first launching from the Kennedy Space Center in Florida on a Falcon 9 rocket for five days in orbit. SpaceX will also review laser-based communication in space launching satellites conduct medical research on the impacts of space radiation on eye health. It could also find a future use for communications between spacecraft. SpaceX’s current generation of Starlink satellites features laser inter-satellite links, allowing them to pass large volumes of data without going through antennas on the ground. The last of the three missions will involve setting a SpaceX Starship rocket, which, when complete, will be the most giant and most powerful spacecraft. The crew members will float out of the hatch and remain tethered to the spaceship at an altitude of approximately 300 miles or 500 kilometers. Since Dragon has no airlock, the whole spacecraft will be exposed to the vacuum of space when the hatch is opened. Thus they would require special extravehicular space suits when going for spacewalks. They will also suspect the impacts of radiation on EarthEarth.
