Space archaeology - preserving our orbital heritage
... debris. For LEO, current guidance is that an asset should be safely de-orbited in a controlled fashion to burn up on re-entry. For satellites in geostationary orbit (GEO), the guidance is to place end-of-life hardware in a much higher ‘graveyard...

mu Space issues proposal request to build a satellite covering Asia-Pacific
...’s satellite with coverage spanning across Asia-Pacific. The high throughput satellite will be on a geostationary orbit (GEO) location at 50.5-degree East, an orbital slot secured on a recent agreement between mu Space and SES, the world’s leading...

Big science from small spacecraft
... radio telescopes on Earth because they are blocked by our ionosphere. If we could position a radio telescope up at geostationary orbit (GEO) or higher, well above the ionosphere, we could observe and characterise these short-lived phenomena, a long...

Aeroshells – from LEO to Mars
...deployment mechanism. Debris mitigation LEO is one of the most commercially valuable regions of outer space (second only to geostationary orbit, GEO), and is situated between altitudes of about 150 km and 2000 km. The key letter in the acronym is the...

Hypersonics and the route to orbit
...point-to-point travel and LEO missions. The next iteration, HELLO-2, will carry 5500 kg to LEO, 1730 kg to geostationary orbit (GEO) and 760 kg to the lunar surface, and will be followed later by a proposed HELLO-3M, a crewed lunar mission. Naturally...

Space junk collision highlights need for intervention
...larger than 5-10 cm in low Earth orbit (LEO) and 30 cm to 1 m in geostationary orbit (GEO) - as well as several thousands to millions of non-trackable debris particles in orbit around the Earth. “These in-orbit collisions and explosions highlight the...
