In search of stable liquids

Most liquids are in suspension. Particles too small to see by naked eye swirl everywhere as gravity and temperature changes move them around. Keeping liquids from separating can be a hassle for the foods we buy in the supermarket, but also for the pharmaceutical industry seeking to extend the shelf life of medicine as long […]

Iodine thruster used to change the orbit of a small satellite for the first time ever

Iodine thruster could slow space junk accumulation

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 […]

Keep this surface dirty

Image: A ‘do not touch’ directive applies to both a Matisse painting and this Matiss experiment on board the International Space Station. Designed to test the antibacterial properties of hydrophobic (or water-repelling) surfaces on the Station, the sample holders of the upgraded Matiss-2.5 experiment have done their work for roughly a year on board and […]
