The article offers information on the three Mars missions launched in July 2020. The first to arrive the planet is the Hope orbiter, the first mission from the United Arab Emirates, which will focus on how gases are able to escape and float away into space. China's Tianwen-1 mission carries a radar system, instruments to analyse dust, a magnetic field detector and a set of cameras.
