We often focus on space observatories that peer beyond Earth. But the vast majority of satellites stare right back at us.

The private Fram2 mission is launching later today, sending a crew of amateurs to an unprecedented polar orbit—a frontier ...

Satellite operators need better space weather models to maximize the life of their satellites and to avoid collisions in low ...

SpaceX plans to send four astronauts into space during Fram2 while becoming the first human spacecraft to cross Earth's polar regions.

Polar orbits take the satellites over the Earth’s poles. The satellites travel very close to the Earth (as low as 200 km above sea level), so they must travel at very high speeds (nearly 8,000 m/s).

"To see a transition in the eccentricities of the orbits at this same point tells us there really is something very different about how these giant planets form versus how small planets like Earth ...

so the satellite appears to remain in the same part of the sky when viewed from the ground. These orbits are 36,000 km above the equator and the satellites travel at 3,000 m/s. These satellites ...
