On September 10, SpaceX, Musk's space exploration technology company, announced the launch of a spacecraft carrying four commercial astronauts on the "Polaris Dawn" mission. The mission will transport the spacecraft to an altitude of about 1,400 kilometers from Earth and let the astronauts attempt the first commercial spacewalk on the "Dragon" spacecraft, test Starlink laser-based communications, and conduct extensive research in microgravity conditions before returning to the ground.
