Is there methane and groundwater on Mars?

ASSOCIATED PRESS

Will humans go to Mars? It’s a topic that gets a lot of airtime, mostly about whether it will be NASA or Elon Musk’s SpaceX that gets there first. What gets lost in the hype is how incredible a place Mars is, and how science is slowly but surely revealing its majesty.

This week saw two major news events on the Red Planet with the announcement of a confirmed methane detection and evidence for water deep below the Martian surface.

Is there methane on Mars?

Back in June 2013, the Curiosity rover detected methane in the atmosphere of Mars. This is not necessarily evidence for life on Mars, despite Curiosity’s other discoveries, but it was controversial. After all, methane on Earth methane is produced by living organisms, as well as by geological processes, but it’s destroyed quickly by atmospheric processes. Was the detection on Mars an anomaly? Or could the methane have been created geologically inside Gale Crater where Curiosity detected it, possibly stored in an underground reservoir?

A double detection

Scientists have gone back to data collected by the European Space Agency’s (ESA) Mars Express orbiter (at Mars since 2003) and reanalyzed the data. The result? They found one case of simultaneous methane detection, the first time a measurement of methane on the Martian surface has been independently confirmed from a probe in orbit. However, the measurements are right at the limit of the instruments’ capabilities. “In general we did not detect any methane, aside from one definite detection of about 15 parts per billion by volume of methane in the atmosphere, which turned out to be a day after Curiosity reported a spike of about six parts per billion,” says Marco Giuranna from the National Institute for Astrophysics – Institute for Space Astrophysics and Planetology in Rome, Italy, the principal investigator for the PFS experiment, and lead author of the paper published in Nature Geoscience. “Although parts per billion in general means a relatively small amount, it is quite remarkable for Mars – our measurement corresponds to an average of about 46 tonnes of methane that was present in the area of 49,000 square kilometers observed from our orbit.”

Trapped by ice?

However, atmospheric analysis suggested that it was unlikely that the source of methane was Gale Crater itself, and that it was probably coming from small, transient geological events that released methane trapped below the Martian surface by permafrost and ice.

Deep groundwater on Mars

Was Mars once wet? Just as methane may occasionally bubble-up on Mars, so might groundwater. We know there is water on Mars, specifically at its poles, and in mid-2018, researchers supported by the Italian Space Agency detected the presence of a deep-water lake on Mars under its south polar ice caps. Now it seems there may be groundwater 750m underground that could create streams of water on its surface near the equator. A paper published by the USC Arid Climate and Water Research Center (AWARE) studied Mars Recurrent Slope Linea. These dried, short streaks of water appear on some crater walls on Mars and were thought to have been created by water or melting snow on the Martian surface. “We propose an alternative hypothesis that they originate from a deep pressurized groundwater source which comes to the surface moving upward along ground cracks,” says the paper’s second author, Essam Heggy. Using images from the High-Resolution Imaging Science Experiment, the work is based on how groundwater works in the desert regions of North African Sahara and in the Arabian Peninsula. The researchers studied Valles Marineris and Mars’ southern mid-latitudes and think that the streaks may come from aquifers in geological fractures as deep as 750m. “We suggest that deep groundwater occasionally surfaces on Mars in present-day conditions,” says the paper.

This inner slope of a Martian crater has several of the seasonal dark streaks called “recurrent slope lineae,” or RSL, that a November 2017 report interprets as granular flows, rather than darkening due to flowing water. The image is from the HiRISE camera on NASA’s Mars Reconnaissance Orbiter.

Why water on Mars is important

“Groundwater is strong evidence for the past similarity between Mars and Earth. It suggests they have a similar evolution, to some extent,” says Heggy. “Understanding Mars’ evolution is crucial for understanding our own Earth’s long-term evolution and groundwater is a key element in this process … it helps us to understand the similarities to our own planet and if we are going through the same climate evolution and the same path that Mars is going.”

Back in June 2013, the Interest rover found methane in the environment of Mars. This is not always proof for life on Mars, in spite of Interest’s other discoveries, however it was questionable. After all, methane in the world methane is produced by living organisms, along with by geological procedures, however it’s ruined rapidly by climatic procedures.

Researchers have actually returned to information gathered by the European Area Firm’s( ESA) Mars Express orbiter( at Mars because2003) and reanalyzed the information. The outcome? They discovered one case of synchronised methane detection, the very first time a measurement of methane on the Martian surface area has actually been separately verified from a probe in orbit. Nevertheless, the measurements are right at the limitation of the instruments’ abilities. “In basic we did not discover any methane, aside from one certain detection of about 15 parts per billion by volume of methane in the environment, which ended up being a day after Interest reported a spike of about 6 parts per billion,” states Marco Giuranna from the National Institute for Astrophysics– Institute for Area Astrophysics and Planetology in Rome, Italy, the primary detective for the PFS experiment, and lead author of the paper released in Nature Geoscience “Although parts per billion in basic indicates a reasonably percentage, it is rather amazing for Mars– our measurement represents approximately about 46 tonnes of methane that existed in the location of 49,000 square kilometers observed from our orbit.”

Was Mars as soon as damp? Simply as methane might periodically bubble-up on Mars, so may groundwater.

Utilizing images from the High-Resolution Imaging Science Experiment, the work is based upon how groundwater operates in the desert areas of North African Sahara and in the Arabian Peninsula. The scientists studied Valles Marineris and Mars’ southern mid-latitudes and believe that the streaks might originate from aquifers in geological fractures as deep as 750 m. “We recommend that deep groundwater periodically surface areas on Mars in contemporary conditions,” states the paper.

This inner slope of a Martian crater has numerous of the seasonal dark streaks called “frequent slope lineae,” or RSL, that a November 2017 report analyzes as granular circulations, instead of darkening due to streaming water. The image is from the HiRISE cam on NASA’s Mars Reconnaissance Orbiter.

Why water on Mars is necessary

” Groundwater is strong proof for the previous resemblance in between Mars and Earth. It recommends they have a comparable advancement, to some degree,” states Heggy. “Comprehending Mars’ advancement is important for comprehending our own Earth’s long-lasting advancement and groundwater is a crucial element in this procedure … it assists us to comprehend the resemblances to our own world and if we are going through the exact same environment advancement and the exact same course that Mars is going.”
