For the first time, astronauts fly over the Poles

On March 31, 2025, humanity took a historic step in its space exploration journey: for the first time, astronauts orbited the Earth’s poles. This achievement was made possible by the Fram2 mission, led by SpaceX, a company that continues to redefine the boundaries of space exploration. Aboard a spacecraft launched by the Falcon 9 rocket from Pad 39A in Florida, the "framonauts"—as they have been dubbed—marked an unprecedented milestone by flying over the polar regions, something never before accomplished by a crewed mission.
 
Who are these pioneers?
 
The Fram2 mission is named after the ship used by Norwegian explorer Fridtjof Nansen during his Arctic expedition in the late 19th century, reflecting the spirit of exploration that drives this modern feat. While specific details about the crew have not been widely disclosed at the time of writing this article, it is known that they are astronauts selected by SpaceX for this groundbreaking mission. This team not only had to prepare for the physical and psychological challenges of spaceflight but also for the unique conditions of a polar orbit, an environment previously unexplored by humans.
 
The importance of orbiting the Poles
 
A polar orbit, unlike the more common equatorial or inclined orbits used in previous space missions, offers a unique perspective of the planet. By passing over the poles, the spacecraft provides unparalleled views of the Arctic and Antarctic, regions critical to understanding climate change and Earth’s geophysical processes. This trajectory also enables the observation of phenomena such as the northern and southern auroras from a privileged vantage point, potentially enriching our knowledge of the interaction between Earth’s magnetic field and solar particles.
 
Moreover, this mission carries significant scientific and technological implications. Polar orbits are ideal for collecting data on climate, polar ice, and the upper atmosphere—areas of study that benefit both science and humanity as a whole. From a strategic perspective, mastering this type of orbit could open new possibilities for future missions, including those targeting other planets with polar features, such as Mars.
 
Why hadn’t this been done before?
 
While polar orbits are not new—uncrewed satellites have used them for decades for tasks like mapping and meteorology—bringing astronauts into this trajectory has been a monumental challenge for several reasons:
 
Costs and Technical Complexity: Polar orbits require more energy to achieve due to their extreme inclination relative to Earth’s equator. This entails higher fuel consumption and more complex logistical planning, which has historically discouraged their use in crewed missions in favor of more cost-effective and safer options like low equatorial orbits.
 
Radiation Risks: Polar regions are more exposed to cosmic and solar radiation due to the configuration of Earth’s magnetic field, which funnels charged particles toward the poles. This poses an additional hazard for astronauts, as crewed missions must ensure the crew’s safety against elevated radiation levels.
 
Communication Limitations: Maintaining constant communication with Earth in polar orbits is more challenging than in equatorial orbits, where ground stations are better aligned with the spacecraft’s path. Before the development of technologies like SpaceX’s Starlink satellite network, this barrier was significant.
 
Historical Priorities: During the 20th-century space race, both NASA and the Soviet Union focused their efforts on goals such as reaching low Earth orbit, landing on the Moon, or establishing space stations. Polar orbits, while useful for satellites, were not considered a priority for crewed missions, which sought more visible and politically significant milestones.
SpaceX overcame these obstacles thanks to recent technological advancements. The use of the Falcon 9, a reusable rocket that reduces costs, combined with the communication infrastructure provided by Starlink, made this mission feasible. Additionally, modern radiation protection systems and meticulous planning enabled the crew to be safeguarded in this hostile environment.
 
A step toward the future
 
The Fram2 mission is not only a technical achievement but also a symbol of the resurgence of space exploration led by the private sector. By bringing humans into a polar orbit, SpaceX demonstrates that the boundaries of what is possible are constantly being redrawn. This milestone could pave the way for future expeditions, whether on Earth—with improved monitoring of the poles—or beyond, in missions requiring unconventional trajectories.
 
In a world where climate change and sustainability are pressing concerns, the ability to observe and study the poles from space with astronauts onboard offers a new tool for science and humanity. The framonauts of the Fram2 mission have not only made history but have also opened a window to a future where space and Earth are more connected than ever.

A tribute to Norway

Naming this space project “Fram” was no coincidence; it pays tribute to Norwegian explorers Fridtjof Nansen, Otto Sverdrup, Oscar Wisting, and Roald Amundsen, who, between 1893 and 1912, reached the Arctic and Antarctic regions aboard the “Fram” (meaning "Forward" in Norwegian), likely the most resilient wooden ship ever built, which is still preserved and can be visited in Oslo, Norway.
 

A chance encounter will take him far away, on a thrilling adventure full of action and emotion that will change his life... but also the lives of everyone around him…
