Starting around 60 km up, in the outermost layers of atmosphere carbon dioxide actually cools the atmosphere, causing it to shrink and contract. A cooling and shrinking MLT will lead to an increase in the longevity of space debris at higher altitudes
A piece of space debris has hit and damaged part of the International Space Station - namely, the Canadarm2 robotic arm. It's a reminder that the low-Earth orbit's space junk problem is a ticking time bomb.
There are at least 34,000 pieces of large debris in Low Earth Orbit. Now spanish scientists has come up with a simple but elegant idea: equip future satellites with a tether system so they can de-orbit themselves at the end of their lives.
A spacecraft has successfully fired a harpoon into a target orbiting Earth in an operation that could help clean-up the tonnes of space junk threatening telecommunications satellites.
In 60 years of space exploration, we've placed almost 7,000 satellites in orbit. Less than a third still function. The rest is dangerous junk - and their number is growing. Here's how we might mitigate the threat.
The Falcon Telescope Network is spreading across the globe. The telescopes will be able to identify any space debris in orbit around Earth that is larger than 10cm by picking up any sunlight that the space trash reflects.
At least 500,000 pieces of space debris threaten satellites and astronauts, but an US -based company says it has a new approach for taking out the garbage.
Researchers combined gecko-inspired adhesives and a custom robotic gripper to create a device for grabbing space debris.
ESTCube-2 is planned to blast off in 2019. The main objective for ESTCube-2 is to test a “plasma brake”. This is a new method of deorbiting satellites, which could help mitigate the problem of space debris.
