A College of Maryland doctoral scholar learning geology helped uncover a potential volcano on Mars that might function a future exploration web site and advance the seek for extraterrestrial life on the planet.
Sourabh Shubham collaborated with Pascal Lee — the lead creator of the examine and a planetary scientist with the SETI Institute and the Mars Institute primarily based at NASA Ames Analysis Middle — to make the invention in December. They offered their findings concerning the volcano, which is taller than Mount Everest, final month on the fifty fifth Lunar and Planetary Science Convention.
“It was proper in entrance of us however we by no means acknowledged it earlier than,” Shubham mentioned. “We had been fortunate to seek out it earlier than anyone else.”
The 2 have been working collectively since 2018 and had been initially inspecting the Noctis Labyrinthus area of Mars — the place the volcano is positioned — to evaluate its candidacy as a web site for human exploration.
The group analyzed pictures and knowledge from numerous sources such because the NASA Mars Reconnaissance Orbiter and Excessive Decision Imaging Science Experiment, in response to their examine.

Final 12 months, Shubham and Lee discovered what they believed to be stays of a glacier blanketed in salt deposits. They seen volcanic ash surrounding the world, which led them to seek out the volcano. The ash from the volcano’s previous eruptions combined with the glacier and chemically fashioned the salt deposits, in response to Lee.
The volcano was eroded past recognition, in response to Lee, which is why it was not found earlier. Researchers are uncertain if the volcano is able to erupting once more, he added.
Scientists already knew there have been volcanoes on Mars, in response to Rod Pyle, an area historian and creator of a number of area exploration books. However this discovering is very necessary as a result of water from the glacier and the potential thermal exercise under the volcano imply there may need been or might at present be microbial life on Mars, he mentioned.
“This can be a as soon as in a technology sort of discovery,” Pyle mentioned. “It’s simply this wonderful achievement that’s extremely laborious to do.”

The researchers are engaged on their peer reviewed paper to additional solidify their findings, however have garnered skepticism from different professionals to this point, Lee mentioned. Due to the potential volcano’s extreme erosion, many scientists assume it might be an influence crater as a substitute.
Hannes Bernhardt, a visiting assistant analysis scientist on this college’s geology division, mentioned being skeptical is a pure a part of the scientific course of. He thinks the offered proof is “convincing,” he mentioned, however doesn’t assume that Shubham and Lee’s discovery will be assured at the moment.
“I used to be fairly startled as a result of it was proper there in our face,” Bernhardt mentioned. “We’d like a skeptical evaluate and we have to actually critically assess the findings and their observations.”
Regardless of the skeptics, the pair are sure they’ve found a volcano, they mentioned.
Lee understands the hesitancy from the scientific neighborhood but additionally thinks these with doubts haven’t regarded on the offered proof rigorously sufficient, he mentioned.
“We’re very assured of what we discovered and have reported,” Lee mentioned.
