Scientists believed Mars was covered in methane. Now it is missing



Just the facts

This is what we know: ESA's ExoMars Trace Gas Orbiter (TGO) reached its orbit around March 2016, when it began its mission to monitor and analyze the Red Planet's atmosphere. Although researchers expected TGO's extremely sensitive sensors to pick up atmospheric methane, it has not yet discovered anyone.

The orbiter can detect trace amounts of methane concentrations as low as 50 parts per trillion – at any elevation in March & # 39; atmosphere. And yet it came back with bupkis.

However, the researchers who work with the project acknowledge that these are preliminary results. There is still a lot of sound to clean out data and more analysis to be done.

Development cases

These preliminary results show a classic example of how there is no evidence that is not the same as the evidence of absence. It is far too early to throw out any evidence of martian methane. The researchers behind this TGO research are convinced that the orbiter's sensors work properly and that NASA and ESA's former methane findings could not be all incorrect, Universe Today .
