SpaceX Nears Historic First Private Spacewalk in Just One Week

SpaceX is once again pushing the boundaries of space exploration with the upcoming Polaris Dawn mission. Set to launch in just one week, this mission marks a significant milestone as it will feature the first-ever private spacewalk. The mission is led by Jared Isaacman, a US billionaire who previously chartered the Inspiration4 mission, the first all-civilian orbital spaceflight in 2021. The Polaris Dawn mission represents not just a technical achievement but also a major step forward in the commercialization of space.

The Polaris Dawn Mission

The Polaris Dawn mission is a five-day expedition that will take place aboard a SpaceX Falcon 9 rocket. The launch is scheduled to take place before dawn next Monday from the Kennedy Space Center in Florida. The mission will carry a crew of four, including Jared Isaacman, SpaceX employees Sarah Gillis and Anna Menon, and pilot Scott Poteet.

Jared Isaacman, who is funding the mission jointly with SpaceX, spoke about the journey so far during a press conference on Monday. “It’s been two and a half years since we announced the Polaris program. It’s been a really exciting journey of development and training,” Isaacman said. He did not disclose the amount he has spent on the Polaris program, which includes a total of three missions.

Advanced Space Suits for the Mission

One of the highlights of the Polaris Dawn mission is the new generation of space suits developed by SpaceX. These suits are white and futuristic in design, marking a departure from the traditional bulky space suits of the past. The suits are designed to withstand the extreme conditions of space, including intense radiation and extreme temperatures.

Elon Musk, CEO of SpaceX, expressed his excitement about the mission on X (formerly Twitter), stating, “This will be epic.

The space suits are not just a design improvement but also a technological advancement. They include built-in cameras that will capture every moment of the spacewalk, providing a unique perspective to viewers back on Earth. Jared Isaacman shared his thoughts on the new suits: “Someday, someone could be wearing a version of the suit as they are walking on Mars. It feels like a huge honor to have that opportunity to test it out on this flight.”

The Crew Members

The crew of the Polaris Dawn mission is a mix of experienced professionals who bring a wealth of knowledge and skills to the mission.

• Jared Isaacman: Mission commander and leader of the mission, Isaacman is a billionaire entrepreneur and space enthusiast. He previously led the Inspiration4 mission.
• Sarah Gillis: A SpaceX employee responsible for astronaut training, Gillis played a key role in training Isaacman for the Inspiration4 mission. This mission will be her first time in space.
• Anna Menon: Another SpaceX employee, Menon has a background in aerospace engineering and previously worked for NASA. She expressed her excitement about the mission, saying, “I’ve spent years trying to put myself in the seat of astronauts in space, and I am really looking forward to learning firsthand what that experience is actually like.”
• Scott Poteet: A close friend of Isaacman, Poteet is a seasoned pilot with 20 years of experience flying fighter jets in the US Air Force. He has undergone rigorous training to prepare for this mission. Poteet described the training as “some of the most challenging training that I’ve ever experienced.”

The crew has undergone extensive and challenging training to prepare for the Polaris Dawn mission. Their training included over 2,000 hours in a simulator, centrifuge sessions, scuba diving, skydiving, and even climbing the Cotopaxi volcano in Ecuador. The goal of this intense training was to prepare the crew for the physical and mental challenges they will face during the mission.

Scott Poteet described the training as incredibly demanding, stating, “I can tell you without a doubt, this has been some of the most challenging training that I’ve ever experienced.”

Mission Objectives

The Polaris Dawn mission has three main objectives:

1. Reaching Record Altitudes: The mission aims to reach an altitude of 1,400 kilometers (870 miles), the furthest distance for a space crew since the Apollo lunar missions. This will be a record-breaking achievement, especially for Sarah Gillis and Anna Menon, who will become the two women to have traveled the farthest from Earth.
2. Laser Communication Test: The second objective is to conduct a laser communication test between the spacecraft and SpaceX’s Starlink satellites. This test will demonstrate the ability to communicate effectively using lasers, which could be crucial for future space missions, especially those that travel beyond Earth’s orbit.
3. First Commercial Spacewalk: The highlight of the mission is the first-ever commercial spacewalk, which will be broadcast live on the mission’s third day. The spacewalk will involve two astronauts venturing outside the Dragon capsule, while the other two remain inside. The spacewalk will be conducted in a lower orbit, and the crew will test the new space suits’ capabilities. Jared Isaacman described the spacewalk as a “hands-free demonstration,” where the astronauts will perform movements to test the suit’s performance.

Challenges of the Spacewalk

The spacewalk presents unique challenges for the crew. Since the Dragon capsule has no airlock, the entire spacecraft will be exposed to the vacuum of space when the hatch is opened. This means that the astronauts must carefully coordinate their movements to avoid any mishaps.

Jared Isaacman and his team have spent considerable time training for the spacewalk, and they are confident in their ability to carry out the mission successfully. The new space suits are designed to protect the astronauts from the harsh conditions of space, but the mission will be a critical test of their effectiveness.

The Role of Private Sector in Space Exploration

The Polaris Dawn mission highlights the growing role of the private sector in space exploration. Companies like SpaceX are playing an increasingly important role in advancing human space exploration, and the mission is a testament to the progress that can be made when private companies are involved. Jared Isaacman praised the private sector’s contributions, stating, “I’d certainly like my kids to see humans walking on the Moon and Mars and venturing out and exploring our solar system. We haven’t even scratched the surface yet. There’s so much to go out and explore and discover along the way.”

Future Missions

The Polaris program includes a total of three missions, with the Polaris Dawn mission being the first. The second mission is expected to be similar, but with more advanced objectives. The third mission, however, will be the most ambitious of them all. It will involve the first crewed flight on SpaceX’s Starship rocket, which is currently under development. The Starship is intended for missions to the Moon, Mars, and beyond.

Conclusion

The Polaris Dawn mission is set to be a historic event in the world of space exploration. As SpaceX prepares for its first-ever private spacewalk, the mission represents a significant achievement for the company and the broader space industry. With new technologies, rigorous training, and a dedicated crew, the mission is poised to make history and pave the way for future private space exploration. As Jared Isaacman said, “We haven’t even scratched the surface yet. There’s so much to go out and explore and discover along the way.”
