Hope: One year at Mars<\/span><\/h2>\n\n\n\n

After 12 months spent observing the Martian atmosphere with its Hope probe, the United Arab Emirates has released a global map of the planet<\/p>\n\n\n\n

On 9 February 2021, the Hope Emirates Mars mission \u2013 the first interplanetary mission from the United Arab Emirates (UAE) \u2013 arrived at the Red Planet.\u201cThe objective of the mission is to study the atmosphere\u2019s variability for a full Martian year \u2013 two Earth years,\u201d says Hessa Al Matroushi, science lead on Hope. \u201cThe maps we have from other missions to Mars have gaps in them. There would be measurements of the planet, say, two times a day and you\u2019d have to predict what\u2019s happening in between \u2013 that\u2019s not accurate. Hope looks at the whole planet, surveying different layers of the atmosphere at different times of day, so we get full coverage. This is something that hasn\u2019t been done before with such accuracy.\u201d<\/span><\/p>\n\n\n\n

Hope began science observations in May 2021 and the team has now released the first set of maps from its Atlas of Mars, tracking atmospheric and temperature changes during the day. This main science phase is set to cover one Martian year, giving a full picture of the Red Planet\u2019s atmosphere.<\/p>\n\n\n\n

Valles Marineris is a 4,000km-long canyon that reaches depths of 7km \u2013 about five times deeper than the Grand Canyon on Earth. It is a tectonic crack, created four billion years ago as the planet cooled. <\/span><\/figcaption><\/figure>\n\n\n\n

The Tharsis <\/strong>region (pictured, below) covers a geological hotspot that has been pushing the terrain upwards for billions of years, creating a 7km-high plateau. It is home to three of Mars\u2019s largest shield volcanoes: Ascraeus Mons, Pavonis Mons <\/strong>and Arsia Mons <\/strong>(from north to south). Olympus Mons <\/strong>(pictured, below left with clouds around the summit), the Solar System\u2019s largest volcano, lies to the west of Tharsis.<\/p>\n\n\n\n

A global view of Mars<\/span><\/strong><\/h4>\n\n\n\n

\u201cAlthough the mission was designed to study the atmosphere, the surface is also a very important component, and we need to understand how the two interact together,\u201d says Al Matroushi. To do this, Hope conducted a \u2018capture\u2019 orbit, where it came very close to the planet, allowing it to take higher resolution images of the surface. It then moved out to its science orbit, which is wide to <\/span>view the whole globe at once (below). \u201cThat was exciting because you can do a lot of surface science \u2013 you\u2019re able to see the rocks and the sand and study different regions, including Valles Marineris <\/strong>and Tharsis,\u201d <\/strong>says Al Matroushi<\/p>\n\n\n\n

Taking the temperature of the Red Planet<\/span><\/strong><\/h4>\n\n\n\n

The Emirates Mars Infrared Spectrometer (EMIRS) looks at infrared light from Mars, generating heat maps of the entire planet at various points in the day. \u201cWe\u2019re looking into the globe\u2019s temperature and understanding its variability, as that impacts the climate,\u201d says Al Matroushi.<\/p>\n\n\n\n

This set of heat maps <\/strong>(below) was created in July 2021, in the season of spring for the Red Planet\u2019s northern hemisphere, and it shows the change in temperature across the whole planet over an average day.<\/p>\n\n\n\n
