Named after the famous polar exploration ship Fram, Fram2 was not the first privately funded and conducted space flight, but it was historic because it accomplished something no other manned space mission had ever accomplished.
The four-person crew lifted off from the Kennedy launch pad 39A using a rented SpaceX Dragon capsule and a Falcon 9 launch vehicle. However, instead of flying in the direction of the Earth's rotation to gain more power, it turned due south.
It is worth noting that the orbits of most manned space missions are tilted from 28.5° to 51.6° to the equator. The largest inclination in history occurred in 1963, when the Soviet Vostok 6 spacecraft carried Valentina Tereshkova, the first woman in space, to an orbit with an inclination of 65°, which was equivalent to the inclination of Fairbanks, Alaska. Today, this record has been broken because Fram2 is tilted at 90°, or at right angles to the equator.
The end result is that the Dragon spacecraft will fly over the North and South Pole 55 times in three to five days, and if it stays in space long enough, it will also fly over every point on Earth.
Although polar orbits are used by many satellites, especially those used for military reconnaissance, no manned flights have been attempted to date, for the following reasons. First, polar orbits require more fuel than equatorial orbits. In addition, the earth's equatorial bulge will frequently cause gravitational disturbances, causing orbital deviations. The atmospheric drag will be greater when flying over the poles, and reentry operations will be much more complicated.
In addition to this, Fram2 will face stronger cosmic radiation as the spacecraft will move out of the Earth's magnetic field at the poles, rapid temperature changes due to sudden changes from sunlight to darkness, and communication problems due to poor ground station coverage in the polar regions.
The Fram2 crew includes mission commander Chun Wang, aircraft commander Jannicke Mikkelsen, aircraft pilot Rabea Rogge and mission expert and medical officer Eric Philips. During their stay in space, they are expected to conduct a series of experiments, including taking the first anatomical X-rays in space, sending television images to amateur radio operators and growing mushrooms in space for the first time.
According to SpaceX, the Dragon spacecraft has carried Crew-1 to and from the International Space Station (ISS), the first civilian orbital mission Inspiration 4, and the first commercial mission Polaris Dawn to conduct a space walk. The first stage booster has now flown six times and landed with power recovery on the "AShortfall of Gravitas" unmanned ship stationed in the Atlantic Ocean.
