SpaceX crew conducts first commercial spacewalk

• The Polaris Dawn mission is also meant to test new technologies and procedures that could be used in future space flights, per NBC News.

The big picture: The spacewalk lasted roughly two hours, including the time needed to repressurize the capsule, and was broadcast live.

• The mission was manned by four crew members, two of whom ventured outside of the Crew Dragon capsule.
• Jared Isaacman, the billionaire commander of the cosmic crew, stepped outside of the capsule first. Next, SpaceX engineer Sarah Gillis ventured out.
• However, the entire capsule was depressurized, meaning all four crew members were exposed to the vacuum of space.

Zoom in: After Isaacman and Gillis returned to the capsule the crew closed the hatch and began repressurizing the spacecraft.

• The spacewalk allowed the astronauts to test out the mobility of their newly designed spacesuits.
