Billionaire Jared Isaacman is the mission commander. Retired US Air Force Lieutenant Colonel Kid Poteat is the pilot. SpaceX’s Sarah Gillis and Anna Menon are mission specialists.
Today (27 August), 4 astronauts are going into space about 700 kilometers above the Earth in a spacecraft of Elon Musk’s company SpaceX. No astronaut has gone into this orbit for more than 50 years. There, 2 astronauts will also do a spacewalk. This will be the world’s first private spacewalk.
The 5-day mission is named Polaris Dawn and will be launched at 4:08 pm. Billionaire Jared Isaacman is the mission commander. Retired US Air Force Lieutenant Colonel Kid Poteat is the pilot. SpaceX’s Sarah Gillis and Anna Menon are mission specialists.
The Crew Dragon capsule of this mission will be launched by SpaceX’s Falcon 9 rocket.
Mission objective: Spacewalk and experiments related to human health
During this mission, the Dragon capsule will attempt to reach an altitude that has not been reached since the Apollo program. Here two astronauts will perform the first private extravehicular activity (spacewalk). During this, they will wear SpaceX’s developed EVA suit.
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 will be part of a human spaceflight crew.

Spacewalk Duration: The spacewalk will last for 20 minutes at a height of 700 km above the Earth
Astronauts Jared Isaacman and Sarah Gillis will do a space walk 700 km above the Earth on the third day of this mission. This walk will last 15-20 minutes. However, this entire process will take about 2 hours. Before the spacewalk, the crew will begin the “pre-breath” process.
In this process, the cabin will be filled with pure oxygen and any trace of nitrogen will be removed. If nitrogen reaches the astronaut’s bloodstream while he is in space, it can cause obstruction of blood flow. Decompression sickness can also occur.
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 up to 7 astronauts into space. It is the only private spacecraft that carries humans to and from the space station. 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.
