The scientists thought Mars was covered with methane. It's gone now


There are reports of great cosmic robbery.

New research shows that Mars, once thought to have an atmosphere rich in methane, is now deprived of organic molecules, reports the Universe today.

If you keep track of space news, you can remember the excitement from 2003 and 2004 when scientists from NASA and the European Space Agency (ESA) announced that they had found Methane on the Red Planet – and pointed out that this could be a sign of the former or even the present alien life.

This finding was reaffirmed in 2014 by the NASA rover Curiositi.

However, a recent exploration of the atmosphere calls into question the presence of gas, according to a survey presented last week by American and European astronomers at the autumn meeting of the US Geophysical Union in 2018.

Just facts

Here's what we know: ESA EcoMars Trace Gas Orbiter (TGO) reached its orbit around March 2016, when it began its mission to monitor and analyze the atmosphere of the Red Planet. Though scientists expected that these highly sensitive sensors would pick up an atmospheric methane, it still did not reveal anything.

Orbiter is capable of detecting traces of methane – a concentration of 50 parts per trillion – at any height in the Martian atmosphere. And yet he came back with bupkies.

However, scientists working on the project admit that these are preliminary results. There is still a lot of noise to get rid of the data and to do more analysis.

Developing Case

These preliminary findings show a classical example of the absence of evidence is not the same as proof of absence. It's too early to throw all the evidence for methane in Mars.

Scientists behind this MET research are confident that the orbiter's sensors are working properly and NASA and the previous methane findings in the ESAs could not have been incorrect, according to the Universe today.

According to scientists, it is possible that the methane is leaked out of the Martian soil, not originated from the atmosphere, which would facilitate the detection of the rover rather than an orbiter such as MET.

Needless to say, this is far from open and closed, and we'll probably find out more about the Mars atmosphere until the TEO completes its results.
