Today is the day that the crew of Polaris Dawn will conduct the first spacewalk ever attempted by private citizens.
Polaris Dawn Mission Commander Jared Isaacman and Mission Specialist Sarah Gillis will conduct the spacewalk, leaving the safety of Crew Dragon Resilience, and test SpaceX's newly designed spacesuits, specially designed to give astronauts more maneuverability.
Coverage of the historic spacewalk has already begun, with the spacewalk expected to begin at 5:58 am ET (9:58 am UTC). The live stream from NASA Spaceflight can be viewed below.
![An artist’s concept looks down into the core of the galaxy M87, which is just left of centre and appears as a large blue dot. A bright blue-white, narrow and linear jet of plasma transects the illustration from centre left to upper right. It begins at the source of the jet, the galaxy’s black hole, which is surrounded by a blue spiral of material. At lower right is a red giant star that is far from the black hole and close to the viewer. A bridge of glowing gas links the star to a smaller white dwarf star companion immediately to its left. Engorged with infalling hydrogen from the red giant star, the smaller star exploded in a blue-white flash, which looks like numerous diffraction spikes emitted in all directions. Thousands of stars are in the background.]](https://assets.iflscience.com/assets/articleNo/76155/aImg/79193/jet-m.jpg)
