When Exomars Rover lands on the surface of the Red Planet in 2021, it will do so in either the Oxum Blanc or the Valais gene. The European Space Agency (ESA) said on Tuesday it had suspended the list of possible landing sites for the mission to the two sites mentioned in previous observations on the presence of water in the planet’s early history.
Oxia Blanum, an easily accessible northern hemisphere with layers of fine minerals that are thought to have been formed by a long water reaction about 3.9 billion years ago, has already been selected as a candidate again in 2015.
“After a two-day meeting with experts from the Mars Science Society and Industry and the Exomarz Project, during which the scientific advantages of the three sites were presented along with initial compliance with engineering constraints, he concluded that the Valis gene would be the second site to be evaluated in more detail.” “About a year before the launch, the final decision on the site, which will become the Xomars 2020 target, will be taken down,” he said.
The Valais gene is a large flow channel located just a few hundred meters from the Oaxia Planum, most likely formed due to ancient flooding. The region is also rich in sediment deposits and contains many minerals that indicate a continuous water presence over several hundred million years.
None of these sites have been explored previously (by humans, at least).”Both candidate sites will explore a period from the history of ancient Mars that has not been studied by previous missions,” said Jorge Vago, a scientist at the European Space Agency’s Rover Exomars project.
The mission of Exomars between Europe and Russia, which aims to establish a robotic rover on Mars in 2021, has been delayed and faces significant cost overruns. As part of the first phase of the endeavor, completed last year, the European Space Agency (ESA) and Rokosmos placed a circle around the Red Planet, but successfully failed to land the landing unit of the demonstration technology.
The ambitious task will consist of a charming platform and a surface platform, as well as a gas tracking device – which is already locked in orbit around the Red Planet and will serve as a relay unit for the 2020 mission. While the solar powered Rover will decompose the rocky terrain from Mars, Through the surface of the collection of samples, the search for organic material markers and the possibility of life – exist or extinct – surface platform, over one year land, will investigate the environment at the landing site.
