ExoMars Trace Gas Orbiter TGO

SpaceNut ... I looked for this orbiter but did not find it...

Who's up for an adventure? You just need to catch a crewed spacecraft to Mars, land near a massive canyon there and go in search of hidden water. The ExoMars Trace Gas Orbiter (TGO) spacecraft has found evidence of "significant amounts of water" in the Valles Marineris canyon system on the red planet.

TGO is operated by the European Space Agency and Russian space agency Roscosmos. The orbiter has an instrument on board that maps hydrogen in the upper layer of Martian soil. Data shows an unusual amount of hydrogen in Candor Chaos, a central region of Valles Marineris, indicating that as much as 40% of the near-surface material in that area could be water.

"With TGO we can look down to one meter below this dusty layer and see what's really going on below Mars' surface -- and, crucially, locate water-rich 'oases' that couldn't be detected with previous instruments," Igor Mitrofanov of the Space Research Institute of the Russian Academy of Sciences said in an ESA statement on Wednesday. Mitrofanov is lead author of a study on the water findings published in the journal Icarus.

Looks like a good place for a Lander Drill probe.

Re: ExoMars Trace Gas Orbiter TGO

Same topic that void created for the location as observed water by the ESA ...
but we can have both still going as I will give a boost to both.

Water in the Valles Marineris: The Grand Canyon of Mars

Well, water in the great canyon on Mars, it seems likely.

I have to study this more.  I will also post this under the section on water for other members to also comment if they might wish.

A little more googling and I find that Nasa had eyes on this back in Jul 7, 2016 Mars Canyons Study Adds Clues about Possible Water

sure it looks smooth but is it possible to land in this very tight area.

Re: ExoMars Trace Gas Orbiter TGO

I did come acorss this mission before in searches and I think people forgot how valuable the Trace Gas Orbiter would be and I think the discussion focued mostly on the failed Schiaparelli lander. http://newmars.com/forums/viewtopic.php?id=7543 Named after the Italian guy who tried to map the surface of Mars but what he called "canali" in Italian, meaning "channels" was mistranslated into English newspapers as "canals". Europe is going to attempt another Lander with Rover in 2022,  the Russians have a lander "Little Cossack" which should deliver the ESA Rover, wheels and suspension of the Rover made by the Canadian Space Agency.

Like a sprinkle of powdered sugar on a red velvet cake, this scene from the ESA/Roscosmos #ExoMars ESA_TGO

captures the contrast of bright white water-ice against the rusty martian soil.
