In the Polaris Dawn mission of Elon Musk’s company SpaceX, today on 12 September, 2 astronauts did a spacewalk about 700 kilometers above the Earth. During the spacewalk, the speed of the spacecraft was 25,000 km per hour. This is the first spacewalk done from a private spaceship. Polaris Dawn mission was launched on 10 September. In this mission, 4 astronauts have gone into space. Out of these, two astronauts, mission commander Jared Isaacman and mission specialist Sarah Gillis, went out for a spacewalk for about 10 minutes. After the spacewalk, the hatch of the spacecraft was closed. In this 5-day mission, the astronauts have gone to an orbit in which no astronaut has gone for more than 50 years. The mission was launched from the Falcon-9 rocket of Elon Musk’s company. 3 photos related to the mission… Oxygen was filled in the cabin before the spacewalk
Before the spacewalk, the crew did the ‘pre-breath’ process. In this process, the cabin was filled with pure oxygen and microscopic particles of nitrogen were also removed. If nitrogen reaches the bloodstream of the astronaut while he is in space, it can cause obstruction in blood flow. This can also cause decompression sickness. In this, air bubbles are formed in the blood or tissue due to rapid decrease in pressure. Mission objective – To conduct experiments related to spacewalk and human health
The objective of this mission was the first private extravehicular activity (spacewalk). Along with this, 36 research and experiments related to human health will also be done. Apart from this, Starlink’s laser-based communication will be tested in space. This is the first time that two SpaceX employees are part of the Polaris Dawn mission. These astronauts are included in the mission… Falcon-9 is the world’s first orbital class reusable rocket
Falcon-9 is a reusable, two-stage rocket built by SpaceX to carry astronauts and payloads to Earth’s orbit and beyond. The Dragon spacecraft is capable of carrying 7 astronauts into space. It is the only private spacecraft that takes 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 of the Polaris program. It is being funded by Jared Isaacman. If everything 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 undergoing testing.
