From a New Scientist article, May 16, 2015:
The United Arab Emirates has announced details of its uncrewed Mars probe, which it plans to launch in 2020 to monitor the planet’s atmosphere from orbit. The spacecraft, named Hope, will be a big step up from the country’s previous space activities as it attempts to compete with other emerging space powers like India and China.
The Mars probe will carry spectrometers for analysing infrared and ultraviolet signals, along with a digital camera. These will measure water, dust and other molecules in the planet’s atmosphere, in an attempt to learn how Mars transitioned from a wet, warm world to the dry, dusty one we see today.
The science goals are similar and complementary to those of MAVEN and MOM, two Mars probes launched last year by NASA and the Indian space agency ISRO.
