Mars missions from China and UAE are set to go into orbit - here's what they could discover

How times have changed since the Apollo era. Within the space of a few days, two space missions from China and the United Arab Emirates (UAE), respectively, are set to reach Mars. The UAE's Hope mission will go into orbit around Mars on February 9. The next day, the Chinese Tianwen-1 mission - an orbiter and lander--will swing into orbit, with a predicted landing date sometime in May.
