The Polaris Program is a planned series of private crewed space missions organized by U.S. billionaire Jared Isaacman.
The missions will be carried out using SpaceX technology, with the rockets, crewed spacecraft and space suits all supplied by SpaceX.
There are several purposes to each of the planned missions, including furthering research on human health in spaceflight, demonstrating SpaceX technology such as Starlink laser-based communications, and raising funds for charitable causes.

The missions will attempt to set a number of space milestones including the highest crewed Earth orbit and the first-ever commercial spacewalk. It will also debut SpaceX’s extravehicular spacesuit.
The program shares its name with Polaris, a constellation of three stars commonly known as the North Star since it appears as a single point of light to the naked eye.
Polaris Program missions
The Polaris Program will consist of three missions in total. They are as follows:
Polaris Dawn
(opens in new tab)
Polaris Dawn is the first of the planned missions under the Polaris Program. As of February 2023, the mission was estimated to take place no earlier than March 2023 after a pushback from its initial launch estimate of Q4 2022.
The mission will involve a crew of four, launching in a SpaceX Crew Dragon capsule atop a Falcon 9 rocket. The crew will then spend up to five days in Earth orbit, during which time they will attempt to reach an altitude of 870 miles (1,400 kilometers) — higher than any previous SpaceX Dragon mission. The Polaris Program website also states that the mission will aim “to reach the highest Earth orbit ever flown,” though it is likely that this means the highest crewed Earth orbit ever flown, which would be higher than the 853 mile (1,373 kilometer) crewed altitude record set by the Gemini 11 mission. Space.com has reached out to a Polaris Program representative for clarification. The Polaris Dawn crew will also attempt the first ever commercial spacewalk using spacesuits designed by SpaceX. According to the mission website, this will help SpaceX develop and scale the suit for future uses.
The mission will also involve 38 research experiments that will help scientists understand more about how space travel affects the human body. Such experiments include the use of ultrasound to measure changes to eye structure in microgravity and determining how the body processes common pharmaceuticals in orbit. Since the crew will pass through Earth’s Van Allen radiation belt, Polaris Dawn is also set to provide data on the impacts of space radiation on human health, which could be useful for future long-distance space missions.
The crew will consist of mission commander Jared Isaacman, pilot Scott Poteet, specialist Sarah Gills, and specialist and medical officer Anna Mennon.
Mission II
As of February 2023, little is publicly known about the second planned Polaris Program mission, including its date, name, purpose, or launch vehicle.
Mission III
Little is known about the third and last Polaris Program mission, except that the launch and crew vehicle is set to be SpaceX’s upcoming Starship vehicle. If successful, Mission III will be the first crewed Starship flight.
Polaris Program FAQs answered by an expert
We asked Svetla Ben-Itzhak, assistant professor of space and international relations at Air University with the West Space Seminar, Air War College, Alabama, and Todd Leif Ericson, Polaris Dawn mission director a few questions about the Polaris Program.

Will private space missions like the Polaris Program change spaceflight, and how?
Ben-Itzhak: Yes, private commercial initiatives in space are already changing spaceflight in two important ways. First, they help to decrease the cost to access space. SpaceX, for instance, singlehandedly, decreased the cost of launch (of both humans and cargo) to space by focusing on reusability and use of COTS (commercial/consumer off-the-shelf) materials.
In the past, traditional, high-value satellites usually cost between $500 MLN [million] to $3+ BLNS [billion] each: today, the cost is in the tens of millions of dollars per satellite. More private citizens have been to space in the last ten years than in the previous fifty years. Second, private space missions have re-ignited the public’s enthusiasm and interest in space and space exploration and have taken technological progress to new highs.
Private individuals — such as Elon Musk, Jared Isaacman, Jeff Bezos, Richard Branson and several more — are investing personal resources in spaceflight not because they seek a quick profit, which is quite impossible when dealing with space, but because they believe. They believe in the importance of space exploration, in investing in space research and development, in reaching for the stars literally and making humans interplanetary species.

What will the future hold for the Polaris Program and the private space industry?
Ericson: Polaris’ missions are designed to build upon each other, demonstrating the skills and technologies required for us to not only return to the moon, but also those necessary when venturing onward to Mars and beyond. Polaris Dawn is the initial step along that road and will accomplish several firsts.
Dawn will break Gemini 11’s record for the highest Earth orbit when it boosts into 1400+ km [870-mile] apogee. This will provide valuable data on the radiation environment well above the ISS’s orbit of 420km and its impacts on modern electronic equipment. Dawn will also perform the first civilian Extra Vehicular Activity (EVA) using a bespoke suit designed, built and tested by SpaceX in just over a year’s time and at a fraction of the cost of current EVA suits. Additionally, Dawn will add high-speed data capability to Dragon via the Starlink satellite network, significantly increasing the bandwidth available to spacecraft.
The second mission will be announced this spring with objectives that build upon the capabilities demonstrated on Polaris Dawn and the third mission will be the first human flight aboard SpaceX’s Starship.
Ben-Itzhak: The future of the Polaris Program and the private space industry is very promising. Decreasing prices and a reignited public interest in space travel will provide a steady flow of customers, excited to participate in space tourism and to invest not only their money and time, but also [their] lives.
The private space industry has been experiencing steady growth over the last two decades. Just between 2005 to 2020, commercial space revenue more than tripled going from $110 BLN to $362 BLN in 2021 (according to the Space Foundation). Morgan Stanley projects that the global space economy will rocket to more than $1 trillion by 2040, with growth concentrated in the commercial space sector. 2021, in particular, was an incredible year for commercial human spaceflight. That year, it generated $425 million in revenue, more than seven times what was previously projected.
In 2021, Virgin Galactic and Blue Origin kicked off their commercial flight services with trips by their founders, Richard Branson and Jeff Bezos, respectively. Then, in April 2022, Space-X launched the Ax-1 mission for Axiom Space, which carried four private astronauts to the International Space Station for $55 million per seat. Axiom has contracted with SpaceX for the Ax-2, 3, and 4 missions expected to take place in coming years.
Why are the Polaris Program and missions like it important?
Ericson: Of the billions of men and women who have called Planet Earth home, up to this point in history, only a mere 628 have traveled outside our atmosphere.
The Polaris Program is important as it marks the beginning of what will be the 2nd Space Age, an era in which spaceflight leaves the exclusive domain of governments and becomes increasingly accessible by the civil world.
Polaris’ first two missions aboard SpaceX’s Falcon9/Dragon will set the foundation for the third mission, the first human flight aboard Starship. Starship, the first fully reusable orbital vehicle, will not only be capable of carrying up to 100 people into orbit at a fraction of current costs but it will also do so at a launch cadence an order of magnitude greater than what is currently possible today. Starship’s low-cost, frequent and rapid access to space will begin to shrink our solar system in the same way the Douglas DC-3 began to shrink our world in the 1930’s.
Ben-Itzhak: Such missions advance scientific and technical knowledge, inspire, and, thus, contribute to the bettering of humanity in both tangible and intangible ways.
Who is Jared Isaacman?
(opens in new tab)
The Polaris Program is headed by Jared Isaacman (opens in new tab), aircraft pilot and billionaire CEO of payment company Shift4. He is also CEO of the military air service contractor Draken International.
In 2021, Isaacman made headlines with the Inspiration4 mission — the first orbital spaceflight with a crew made entirely of private citizens, including himself as mission commander. As with the Polaris Program, Isaacman developed the Inspiration4 mission plan in cooperation with SpaceX, which provided a Dragon capsule and Falcon 9 launch vehicle. The three-day low-Earth orbit mission was ultimately a success and raised over $240 million (opens in new tab) for St. Jude Children’s Research Hospital in Memphis, Tennessee — a hospital that researches and provides treatment and cures for pediatric diseases including cancer.
Isaacman will serve again as mission commander for the Polaris Dawn mission. Outside of spaceflight, he has a claimed 7,000-plus flight hours of aviation experience.
Support to St. Jude Children’s Research Hospital
Like the Inspiration4 mission that precedes it, the Polaris Program will provide support (opens in new tab) to St. Jude Children’s Research Hospital.
“As little as we understand about the worlds beyond ours, there’s so much we still don’t understand about our bodies,” said Isaacman (opens in new tab) after visiting the Inspiration4 Advanced Research Center at the hospital in 2022 — a facility which was funded in part by the mission it is named after. “Walking through the Inspiration4 Advanced Research Center really reinforced for me the importance of St. Jude and the mission and everything they’re trying to accomplish.”
St Jude Children’s Research Hospital is notable for having treated Inspiration4 crew member Hayley Arceneaux, a pediatric cancer survivor when she was a child. She later became a physician assistant at the hospital. With Inspiration4, Arceneaux became the first pediatric cancer survivor to go to space and the first astronaut with a prosthetic body part.
