Private mission by SpaceX (not to the ISS).
Landing near Dry Tortugas NW of Key West, Florida.

This Crew Dragon mission will take advantage of Falcon 9 and Dragon's maximum performance, flying higher than any Crew Dragon mission to date and endeavoring to reach the highest Earth orbit ever flown. Orbiting through portions of the Van Allen radiation belt, Polaris Dawn will conduct research with the aim of better understanding the effects of spaceflight and space radiation on human health.

At approximately 700 kilometers above the Earth, the crew will attempt the first-ever commercial extravehicular activity (EVA) with SpaceX-designed extravehicular activity (EVA) spacesuits, upgraded from the current intravehicular (IVA) suit. Building a base on the Moon and a city on Mars will require thousands of spacesuits; the development of this suit and the execution of the EVA will be important steps toward a scalable design for spacesuits on future long-duration missions.

The Polaris Dawn crew will be the first crew to test Starlink laser-based communications in space, providing valuable data for future space communications systems necessary for missions to the Moon, Mars and beyond.

While in orbit, the crew will conduct scientific research designed to advance both human health on Earth and our understanding of human health during future long-duration spaceflights. This includes, but is not limited to:

Using ultrasound to monitor, detect, and quantify venous gas emboli (VGE), contributing to studies on human prevalence to decompression sickness;

Gathering data on the radiation environment to better understand how space radiation affects human biological systems;

Providing biological samples towards multi-omics analyses for a long-term Biobank; and

Research related to Spaceflight Associated Neuro-Ocular Syndrome (SANS), which is a key risk to human health in long-duration spaceflight.

SpaceX and Polaris Dawn will also collaborate with the Translational Research Institute for Space Health (TRISH), BioServe Space Technologies at the University of Colorado Boulder, Space Technologies Lab at Embry Riddle Aeronautical University, Weill Cornell Medicine, Johns Hopkins University Applied Physics Laboratory, the Pacific Northwest National Laboratory, and the U.S. Air Force Academy.

On September 12, 2024 Jared Isaacman and Sarah Gillis performed the first commercial spacewalk ever (1h 46m). They stepped out of the Crew Dragon one after the other for about 20 minutes. They remain secured via foot straps that are attached to a kind of ladder at the other end. In contrast to external missions on the ISS space station, they are not supplied with breathing air via a backpack, but via a hose from the spacecraft.
Scott Poteet and Anna Menon remained in the depressurized capsule and made an IVA.

Polaris Dawn astronaut Sarah Gillis performed the first known violin solo in space, playing "Rey's Theme," from the "Star Wars" series. The violinist shares how she prepared for the out-of-this-world moment to inspire the world.
