Exomars Trace Gas Orbiter.
Why Exomars mission is so important for humanity?
All about the Exomars mission and news.
Exomars is approaching the Red Planet.

There's concern that the European-Russian Exomars 2020 mission could become Exomars 2022.
In this orbit, Exomars Trace Gas Orbiter can finally
make its instruments work optimally.
Exomars TGO
and the Exomars rover share the same name because their missions are complementary.
The Exomars Trace Gas Orbiter,
launched in 2016, will operate as the rover's data-relay satellite.
For many months, Exomars has reduced its speed by more than 780 meters per second.
The Exomars team continues to troubleshoot the parachute design
following an unsuccessful high-altitude drop test last week.
Hopefully this will be better for the Exomars rover which has a much larger scientific payload.
Two tests conducted in May and August 2019 showed that Exomars' parachutes are not functioning properly.
Exomars will also try to determine the regional
and seasonal variations of these gases and many other gases.
Exomars TGO should also try to locate
ice reservoirs on the surface of Mars or in slightly deep.
The Exomars and March 2020 rovers,
which will arrive on the red planet in 2021, could conclude the debate.
Exomars will be able to drill up to two meters deep,
while the Curiosity rover can drill only a few centimeters deep.
The Exomars program rover,
Rosalind Franklin, will take off in 2020 on the same launch window as the Chinese mission Chang'e 5.
The Exomars rover will land in the Oxia Planum Basin,
which was able to shelter a lake a few billion years ago.
Several Exomars parachute tests have been conducted
at a Swedish Space Corporation site, European Space Agency(ESA) officials wrote in a statementyesterday(Aug. 12).
The Exomars team made some changes to the parachute system's
design before the next high-altitude test on Aug. 5, which focused just on the 115-foot-wide chute.
The orbit of Exomars TGO allows it to take pictures early in the morning
or late at night, and therefore to observe the Martian sites with very different lights.
It is therefore a real geological, chemical
and possibly biological survey that will take place during the next five years, provided that the Exomars rover arises and works without problems.
By optimising the wavelength range of the detectors, using an alternative diffraction
grating and making a few minor changes to the electronics, we now have an exciting opportunity to reuse the technology that we have developed for Exomars.".
