Mission commander Jared Isaacman was the first to exit the spacecraft for the spacewalk. After him, mission specialist Sarah Gillis did the spacewalk.
Today on 12 September, in the Polaris Dawn mission of Elon Musk’s company SpaceX, two astronauts did a spacewalk about 700 kilometers above the Earth. During the spacewalk, the speed of the spacecraft was 25,000 Km. This is the world’s first private spacewalk.
The Polaris Dawn mission was launched on September 10. In this mission, 4 astronauts have gone into space. Two of these astronauts, mission commander Jared Isaacman and mission specialist Sarah Gillis, went out for a spacewalk for about 10 minutes.
After the spacewalk, the spacecraft’s hatch was closed. In this 5-day mission, the astronauts went to an orbit where no astronaut had gone for more than 50 years. The mission was launched using Elon Musk’s company’s Falcon 9 rocket.
The Polaris Dawn mission carried astronauts aboard SpaceX’s Crew Dragon capsule.

Mission objective: Spacewalk and experiments related to human health
The objective of this mission is the first private extravehicular activity (spacewalk). During the mission, 36 research studies and experiments related to human health will also be conducted. Apart from this, Starlink’s laser-based communication will be tested in space. This will be the first time that two SpaceX employees are part of a human spaceflight crew.
The cabin was filled with oxygen before the spacewalk
Before the spacewalk, the crew began a “pre-breath” process. This process filled the cabin with pure oxygen and removed any traces of nitrogen. If nitrogen enters the astronaut’s bloodstream while in space, it can cause blood flow problems and decompression sickness.
Falcon 9 is the world’s first orbital class reusable rocket
The Falcon 9 is a reusable, two-stage rocket built by SpaceX to carry people and payloads to Earth orbit and beyond. The Falcon 9 is the world’s first orbital class reusable rocket.
The Dragon spacecraft is capable of carrying 7 astronauts into space. It is the only private spacecraft that carries humans to the space station and brings them back. Dragon’s first test flight took place in 2010.
Polaris program: Polaris Dawn is the first of three planned missions
Polaris Dawn is the first of three planned missions in the Polaris program, which Isaacman is funding. If all goes according to plan, the third Polaris flight will be Starship’s first crewed mission. Starship is the world’s most powerful rocket, which is being tested.
