SpaceX’s historic Polaris Dawn mission: how to watch the launch

SpaceX is getting acceptable to acceptable retired connected its historical Polaris Dawn mission, which volition nonstop 4 astronauts into orbit aboard its Crew Dragon capsule. The five-day travel done the Van Allen radiation belts volition see the archetypal spacewalk done by backstage astronauts.

If you’re funny astir the mission, here’s what you should cognize and however to ticker it live.

What is the Polaris Dawn mission?

First announced successful 2022, Polaris Dawn is simply a ngo funded by billionaire and backstage astronaut Jared Isaacman.

Since the capsule volition walk done the Van Allen radiation belts, the ngo volition besides lend to probe astir the effects of abstraction radiation connected the quality body. Additionally, the Polaris Dawn unit volition trial Starlink’s outer net exertion to pass with Earth, arsenic good arsenic behaviour probe connected decompression sickness and Spaceflight Associated Neuro-Ocular Syndrome.
