For the first time in human history, a fleet of three probes deployed from the UAE, China and the US set sail in July 2020 and took the seven-month interplanetary journey to Mars. The spacecraft from the UAE and China managed to enter Mars orbit on February 9 and 10, respectively. Although the last to reach Mars, Percy will be the first to land, because the UAE craft is designed only to orbit and Tianwen-1 will spend three months or so orbiting before a planned landing in May or June.
