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).

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 ...

There's a new race in space, but it's not where you might think. It's happening close to home – in the nearest bit of space, right on the edge of Earth's atmosphere. High in the skies of Earth ...

Although other experiments have been conducted with satellites in geostationary orbits, this is the first ... increase interconnectivity between different providers, especially as the technology ...

The SPADEX mission will involve launching the satellites into slightly different orbits using a single rocket. The satellites will travel at approximately 28,000 km/h and aim to perform a ‘space ...
