    SpaceX Launches Polaris Dawn: First Private Spacewalk Set for Historic Mission

    SpaceX Launches Polaris Dawn Mission, Aiming for First Private Spacewalk

    SpaceX launches Polaris Dawn. Early on Tuesday, four private astronauts blasted off aboard a modified SpaceX Crew Dragon capsule, marking the beginning of the Polaris Dawn mission. This five-day mission will test new spacesuit designs and attempt the first-ever private spacewalk.

    Crew Dragon’s Riskiest Private Mission

    The crew consists of a billionaire entrepreneur, a retired military pilot, and two SpaceX employees. They launched from NASA’s Kennedy Space Center in Florida at 5:23 a.m. EST (0923 GMT) after a two-hour delay due to unfavourable weather. Shortly after liftoff, the Falcon 9 booster cleared the launch tower, signalling the successful start of the mission.

    This marks SpaceX’s fifth private mission with Crew Dragon, and it is considered the riskiest so far. The spacecraft will enter an oval orbit, coming as close as 190 km (118 miles) to Earth and extending as far as 1,400 km (870 miles), the greatest distance humans have travelled from Earth since the Apollo missions ended in 1972.

    Delays and Challenges

    Last month’s launch attempt was delayed due to a helium leak in SpaceX’s ground equipment. The issue was resolved, but a Falcon 9 booster recovery failure in an unrelated mission caused further delays. Fortunately, Tuesday’s launch went ahead as planned despite a slight weather-related delay.

    The First Private Spacewalk

    The spacewalk is planned for the mission’s third day at an altitude of 700 km, lasting approximately 20 minutes. SpaceX’s Crew Dragon lacks an airlock, so the entire cabin will depressurise before astronauts Jared Isaacman and Sarah Gillis step outside, tethered by oxygen lines. This will be the first time non-government astronauts conduct a spacewalk.

    The procedure is similar to the first US spacewalk in 1965, when a Gemini capsule was depressurised and an astronaut ventured outside while tethered to the spacecraft.

    Crew and Mission Goals

    Jared Isaacman, 41, founder of Shift4 Payments, is financing the Polaris Dawn mission, just as he did with his Inspiration4 mission in 2021. He is joined by mission pilot Scott Poteet, 50, a retired Air Force lieutenant colonel, and SpaceX engineers Sarah Gillis, 30, and Anna Menon, 38.

    For the spacewalk, Isaacman and Gillis will step outside the spacecraft, while Poteet and Menon will remain inside. The crew will also participate in scientific experiments designed to study how cosmic radiation and the space environment affect the human body. These experiments will add to decades of research conducted on the International Space Station (ISS).

    Looking Ahead: The Polaris Program

    The Polaris Dawn mission is the first in a series of private missions funded by Isaacman. A follow-up mission aboard SpaceX’s Crew Dragon is planned, with an eventual flight on the company’s Starship rocket, which is designed for missions to the Moon and Mars.

    SpaceX’s Role in Modern Space Travel

    Since NASA retired the Space Shuttle in 2011, SpaceX’s Crew Dragon has been the only US crew-rated spacecraft in operation. It has completed nine missions to the ISS for NASA and has also flown four private missions. Boeing’s Starliner spacecraft, designed to compete with Crew Dragon, has faced setbacks, with propulsion system issues delaying its most recent NASA test mission.
