Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! SpaceX's Polaris Dawn mission made history with the firstever commercial spacewalk, but it was a risky endeavor that pushed the boundaries of human spaceflight. The crew ventured further than anyone has in over 50 years, reaching the intense radiation of the Van Allen belts. But the most dangerous part? A spacewalk without an airlock, exposing the entire crew to the vacuum of space.

In this video, we talk about the Polaris Dawn mission, exploring the risks, the science, and the motivations behind this daring feat. We'll examine the technology behind the new spacesuits, the dangers of decompression sickness, and the parallels with the tragic OceanGate Titan mission.
