Source: China – South China Morning PostResearchers at Beihang University in Beijing say they have found that shock waves can occur in space, destabilising objects travelling at very high speeds.This could have a big impact on “air-breathing” satellites being designed to use molecules of air, rather than chemical fuels, to propel themselves in orbit.The shock waves had the potential to not only destabilise a satellite, but also drive the molecules away, reducing the device’s ability to collect the propellent and shortening its…Read More
