Iodine thruster could slow space junk accumulation – Phys.org

For the first time ever, a telecommunications satellite has used an iodine propellant to change its orbit around Earth.
The small but potentially disruptive innovation could help to clear the skies of space junk, by enabling tiny satellites to self-destruct cheaply and easily at the end of their missions, by steering themselves into the atmosphere where they would burn up.
The technology could also be used to boost the mission lifetime of small CubeSats that monitor agricultural crops on Earth or…
