For the first few months of 2021, the Martian atmosphere was buzzing with new visitors from Earth. First, it was the UAE Space Agency’s Hope probe, followed by the Chinese Tianwen-1 entering orbit.
More recently Nasa landed the biggest-ever rover on Mars and its companion, an ingenious helicopter, both of which have been setting new milestones since.
The next visitor to the planet will be Tianwen-1 mission’s lander, which will attempt to reach the surface of the Mars in mid-May. To enter the Martian atmosphere, it will use a slightly different technique to previous missions.
Landing on Mars is notoriously dangerous – more missions have failed than succeeded. A successful Mars landing requires entering the atmosphere at very high speeds, then slowing the spacecraft down just the right way as it approaches its landing location.

For several years, strange spider-like formations have been visible on the surface from orbit, dark and spindly against the planet s red deserts. Called araneiforms by scientists, their location near Mars south pole has led to theories that their formation was seasonally influenced.
