Once upon a time the USSR and the USA fought for dominance in space. Now countries from all over the world are headed out past the troposphere. Here’s more from the UK Science Museum:
In early 2021, three spacecraft speeding towards Mars will reach the red planet. The arrival of the United States’ Mars 2020, China’s Tianwen-1 and the United Arab Emirates’ Hope, will generate national pride and celebration in those three countries.
Just a few days before this year’s national day, the UAE’s mission executed a third and final mid-course correction. All planetary missions need these to make sure they hit their target! That Hope required only three such manoeuvres on the way to Mars – it can be far more – was itself a source of joy for the young space engineers and scientists working on their first ever interplanetary mission.
