UAE
UAE unveiled its mission to send an unmanned probe to Mars. The probe, named Al Amal or Hope, will create mankind’s first integrated model of the Red Planet’s atmosphere. The unmanned probe will leave Earth in 2020 on a mission designed to complement the science work of other missions and fill important gaps in human knowledge. Its unique orbits and instruments will produce entirely new types of data that will enable scientists to build the first truly holistic models of the Martian atmosphere. It is the first Mars mission attempted anywhere in the Arab world.Reference
