The United Arab Emirates ' Martian orbiter Hope just provided a spectacular unexampled view of Deimos , one of Mars ' two pocket-size moons . According to findings presented at theEuropean Geosciences Unionmeeting this week , the observation from a flyby on March 10 indicate that Deimos is made of the same cloth as Mars itself — suggest the moon form at the same fourth dimension as Mars , and is n’t a becharm asteroid , as some theory have proposed .
These observance revealed a never - before - seen perspective of Mars and Deimos .
Mars' tiny moon, Deimos, appears to be made of the same sorts of rocks as Mars itself, challenging theories about its formation.
" Mars was in the setting — and that was just brain - fellate , honestly , " mission leaderHessa Al Matroushi , of the Mohammed Bin Rashid Space Centre in Dubai , distinguish Nature.com .
Humanity has been exploring Mars for decade , but our probes mostly stayed near to the Red Planet ’s airfoil . Deimos is tidally locked with Mars , meaning the same side always present the planet , so probes near Mars see only one side of the small Sun Myung Moon , too — that is , until Hope arrive on the scene .
Also do it as the Emirates Mars Mission ( EMM ) , Hope launched in mid-2020 andarrived at Marsin early 2021 . EMM is the first interplanetary ballistic capsule from an Arab country , and it primarily investigated changes in the Martian atmosphere . Once the probe completed that primary commission , the EMM squad decided to use the remaining redundant propellant to boost the spacecraft into a higher orbit above Deimos , allowing the scientists to envision the far side of the Martian moon in detail for the first time .
Deimos appears to be low in carbon, suggesting that it is not a captured asteroid, but an ancient piece of Mars itself.

epitome from Hope ’s first Deimos flyby bring out the petite lunation — which is only 7.7 Admiralty mile ( 12.4 kilometers ) wide , or about half the length of Manhattan , New York — in multiple wavelengths fromultraviolettoinfrared . Deimos appear relatively like at various wavelength , indicating that it consists of Mars - like material or else of the usual carbon copy - rich stuff of asteroids .
" If there were carbon or organic fertilizer , we would see spikes in specific wavelengths , " Al Matroushi add together .
This is surprising , as scientists often considered Deimos a captured asteroid . Instead , it seems like a chunk of Mars itself , perhaps broken off in a long - agone hit . Earth ’s moon is thought to have formedfrom a like collision , gazillion of years ago — perhaps giving our planet one more thing in common with its bouldered red neighbour .
