Yesterday, the Arab space probe Hope, or Al Amal, correctly entered the planet Mars orbit. Launched on July 20, 2020, Hope kept its six engines burning for 27 minutes to slow down to the speed needed to enter orbit, an automated maneuver that required absolute precision to prevent the spacecraft from going over Mars or crashing to the Martian surface. The lights of the tallest skyscraper in the world, the Burj Khalifa in Dubai, were switched on to celebrate the success of the first Arab mission.
