Polaris Dawn Mission: Polaris Dawn of Elon Musk’s SpaceX has returned to Earth after a successful space journey. According to local time, it made a successful landing in the Gulf of Mexico at 3:37 am on Sunday. This was the world’s first commercial space walk mission. Polaris Mission is a joint mission of billionaire Isaacman and Elon Musk. The main objective of this mission is to do commercial space exploration in space. But, the biggest thing is that how did all the crew members remain comfortable at a height of 14000 feet (which has not been possible till now in the history of 50 years), at a speed of 27 thousand kilometers per hour, and at a temperature of 1900 degrees Celsius? With which special technology were they kept safe?
Actually, the main objective of this SpaceX mission was to test the space capsule and space suit made in the agency. When Polaris’ Crew Dragon capsule was in the process of “de-orbit burn” i.e. tearing through the Earth’s atmosphere, its temperature reached about 1,900 degrees Celsius (3,500 degrees Fahrenheit). At the same time, the capsule was returning to Earth at a speed of 27,000 kilometers per hour. But, due to the Crew Dragon’s heat shield being attached, the crew was feeling comfortable temperature. It is located at the bottom of the 13-foot-wide (4-meter-wide) capsule.

Who were the riders
The Polaris Dawn mission was launched on September 10 with the help of SpaceX’s Falcon-9 rocket (reusable rocket). In the five-day journey mission, a feat has been accomplished which could not be done in the last 50 years. 4 crews reached a height of 1408.1 kilometers in the Earth’s orbit. The 4 crew members included Jared Isaacman, Scott “Kid” Poteat, Sarah Gillis and Anna Menon, who did their first private space walk in space.
What was in the crew member’s suit?
The space suits of the four crew members involved in the Polaris Dawn mission were prepared in a very special way. Their dress is called Extravehicular Mobility Unit (EMU). The suit is made of fiberglass shell, the clothes of hands and feet are made of fabric limbs. There is an outer layer of ortho fabric, which is made of a strong material made of Gore-Tex, Kevlar and Nomex. Space provides them protection. A backpack unit is installed on the upper part of the PLSS suit which supplies oxygen.
