   Explanation: On July 23, this Long March 5 heavy-lift rocket rose into
   a blue morning sky from China's Hainan Island Wenchang Satellite Launch
   Center. [6]The rocket carried an orbiter, lander, and rover to ask
   Heavenly Questions on the ambitious [7]Tianwen-1 mission to Mars. In
   fact Tianwen-1 was the second of three missions scheduled for a July
   departure to the Red Planet. The United Arab Emirates launched its
   [8]Amal (Hope) Mars probe on July 19. NASA's launch of its [9]Mars
   Perseverance Rover from Cape Canaveral Air Force Station, USA is
   scheduled [10]for July 30. That is the last planned [11]Mars launch for
   2020 though. The minimum-energy [12]launch window for an [13]expedition
   to Mars is coming to a close in 2020 and will reopen in 2022.
