The Next Big Leap in Private Space Missions
the staff of the Ridgewood blog
Ridgewood NJ, in an era where private spacecraft routinely dock with the International Space Station (ISS), it can be challenging for any one mission to stand out. However, Polaris Dawn, a collaboration between SpaceX and Shift4 CEO Jared Isaacman, is set to make headlines. Launching on Monday, August 26, from Kennedy Space Center, this ambitious mission will push the boundaries of private space exploration.
What Makes Polaris Dawn Unique?
Polaris Dawn isn’t just another space mission. It’s the first in 52 years to send humans through the Van Allen belts, bands of high-energy radiation surrounding Earth. This long, narrow orbit will be a significant milestone in space travel, with the crew of four astronauts aboard a SpaceX Crew Dragon capsule. Halfway through their 5-day mission, two crew members will attempt the first-ever spacewalk by private astronauts, adding to the mission’s high-risk profile.
Testing the Next Generation of Space Suits
One of Polaris Dawn’s primary goals is to test SpaceX’s new extravehicular activity (EVA) suits, designed for deep space exploration. These suits, lighter and more maneuverable than their predecessors, will be worn by Isaacman and mission specialist Sarah Gillis as they attempt a spacewalk. This test marks a significant departure from traditional space missions, with non-government-employed astronauts performing this critical task for the first time.
The new suits also feature a heads-up display, offering real-time data on mission clock, pressure, temperature, and humidity—a first in space exploration. The upcoming mission will serve as the ultimate test for these suits, especially since the crew will need to depressurize their spacecraft before stepping outside.
A High-Stakes Spacewalk
The spacewalk planned for Polaris Dawn is set to be a historic event, reminiscent of the very first American spacewalk in 1965. However, instead of using an airlock like the ISS, the Crew Dragon capsule’s main hatch will be opened, exposing the entire cabin to the vacuum of space. Isaacman and Gillis will venture outside, tethered to the capsule by life-support cables, while the remaining two astronauts manage the ship’s systems from inside—also exposed to the vacuum.
Cutting-Edge Medical Research in Space
Polaris Dawn is not just about testing new technology; it’s also a significant step forward in understanding how space affects the human body. During the mission, the crew will conduct over 30 experiments, including studies on how microgravity and cosmic radiation impact human tissues, bone and muscle loss, and vision changes. These studies aim to advance our knowledge of space health, bringing us closer to safer and longer human spaceflight.
Pioneering the Future of Space Exploration
Polaris Dawn is much more than a private space mission. It’s a bold experiment in the potential of commercial space travel, pushing the boundaries of what private entities can achieve in space. With its combination of technological innovation, high-risk spacewalking, and groundbreaking medical research, Polaris Dawn is a mission that could shape the future of space exploration. Keep an eye on this one—it’s a mission that could change everything.

Yeah, we haven’t had a real space disaster in awhile. This should be interesting.
2 astronauts are currently stuck on the International Space Station
And the rest of the ISS crew? Are there “stuck” there too? Yea, they’re not exactly alone up there running out of Tang.

Do you understand the difference between “stuck up there” and “alone up there” ?
They signed up to be up there for 8 days.
As it stands now, they won’t get back before 8 months.
We don’t belong up there.
