Polaris Dawn rocket launch: Meet the astronauts headed to space for historic spacewalk mission

Polaris Dawn mission: What to know about historic spacewalk

"Dr. Addie Dove, a planetary scientist and Associate Professor in the Department of Physics at the University of Central Florida, joins us to discuss Tuesday's historic Polaris Dawn spacewalk mission.

The Polaris Program, designed to test and develop new spaceflight technology, will begin a new chapter in commercial space exploration with the launch of its first mission, Polaris Dawn, using SpaceX's Falcon 9.

The mission will include the first commercial spacewalk with a next-gen spacesuit, an attempt to reach the highest altitude since Apollo, and testing new communication technology via Starlink.

A four-hour launch window was to have opened at 3:38 a.m. ET on Aug. 28, with two additional launch opportunities at 5:23 a.m. ET and 7:09 a.m. ET. SpaceX said the mission was delayed again due to an unfavorable weather forecast in Dragon’s splashdown areas off the coast of Florida. This weather also impacted a backup launch opportunity for Thursday, Aug. 29.
