SpaceX has announced a new launch date for the highly anticipated Polaris Dawn mission, now targeting Tuesday, September 10, 2024.
This mission, which will feature the first-ever commercial spacewalk, has faced several delays but is now scheduled to launch from Kennedy Space Center. The crew is preparing to embark on a groundbreaking journey that will push the limits of commercial space exploration.
New Launch Details and Backup Opportunities
The updated launch is set for 3:38 a.m. EDT on September 10 from Launch Complex 39A at Kennedy Space Center. SpaceX has also prepared additional launch windows at 5:23 a.m. and 7:09 a.m. should any complications arise during the initial attempt. Weather, which currently offers a 40% chance of favorable conditions for liftoff, will play a significant role in determining whether the mission proceeds on Tuesday.
If the mission cannot proceed on September 10 due to technical or weather-related issues, a backup launch window has been scheduled for Wednesday, September 11, with the same times. SpaceX announced these updates on X (formerly Twitter), stating: "Targeting no earlier than Tuesday, September 10 for Falcon 9’s launch of the Polaris Dawn mission. Weather is currently 40% favorable for liftoff, and conditions at the possible splashdown sites for Dragon’s return to Earth remain a watch item."

The Falcon 9 rocket will carry the Dragon capsule, which is expected to transport the crew into a higher orbit than any human mission since the Apollo program, surpassing even the altitude of the International Space Station (ISS).
Crew and Mission Objectives
The Polaris Dawn crew, led by Jared Isaacman, a billionaire entrepreneur who previously commanded the Inspiration4 mission, will attempt several major milestones during their five-day mission. The four-member team includes Scott “Kidd” Poteet as pilot, and SpaceX engineers Sarah Gillis and Anna Menon, who will serve as mission specialists. Menon, in addition to her role as a mission specialist, will act as the medical officer for the crew.
One of the most anticipated aspects of this mission is the first-ever commercial spacewalk, which will test SpaceX’s extravehicular activity (EVA) suits. Unlike traditional spacecraft equipped with an airlock, the Dragon capsule does not have one, meaning the entire spacecraft will have to be depressurized when the crew opens the hatch to conduct the spacewalk. All four astronauts will be exposed to the vacuum of space, relying on the custom-designed EVA suits for life support. The crew will test these suits, developed by SpaceX, for future missions that could potentially take humans further into space, including destinations such as Mars.
In addition to the spacewalk, the Polaris Dawn mission will focus on scientific and technological advancements. The crew is set to conduct over 40 experiments designed to study the effects of long-duration spaceflight on the human body. These studies are critical for future deep-space exploration, where astronauts may face extended periods in space. Furthermore, the mission will test a laser-based communication system using SpaceX’s Starlink satellites, which could revolutionize satellite communications during future missions.
Why the Polaris Dawn Mission Matters
The Polaris Dawn mission is the first of three human spaceflights planned under the Polaris Program, a series of missions designed to test and advance SpaceX technology in preparation for future deep-space exploration. This mission will see the Dragon capsule reach an altitude of 870 miles, the highest since the Apollo missions, as it passes through the dangerous Van Allen radiation belts—a region of charged particles surrounding Earth. Successfully navigating this high-radiation environment will provide critical data on how to protect both spacecraft and crew from radiation exposure on future missions.
Led by Isaacman, the Polaris Dawn crew represents a significant step forward in the commercial spaceflight industry, demonstrating that private companies can push the boundaries of space exploration. Isaacman, reflecting on the mission’s delays and challenges, posted on X, “Space exploration demands patience, resilience, and teamwork... Together, we are pushing the boundaries of what’s possible and continuing humanity’s journey to the stars.”
I wanted to share some updates:
- The primary factor driving the launch timing for Polaris Dawn is the splashdown weather within Dragon's limits. Unlike an ISS mission, we don’t have the option to delay long on orbit, so we must ensure the forecast is as favorable as possible… pic.twitter.com/3cKEjjVqvC

The mission is not just about reaching new heights but about laying the groundwork for future space missions. By testing new technologies like the EVA suits and the Starlink-based communication system, Polaris Dawn is helping to prepare for more ambitious goals, such as the human exploration of Mars. The data and insights gained from this mission will shape the future of human space exploration, making deep-space travel safer and more feasible.
With the launch just days away, all eyes are on Kennedy Space Center, as the Polaris Dawn mission prepares to make history.
