Does this ancient glacier on Mars hold the key to human exploration there?
The remains of a glacier on Mars have been discovered via the HiRISE camera attached to the Mars Reconnaissance Orbiter. If the ice is confirmed, it would have significant implications for humans who may land there one day.on Wednesday. It released the image that features light-toned deposits consisting of sulfate salts, crevasse fields, and moraine bands that are signs of a “relict glacier.”
“What we’ve found is not ice, but a salt deposit with the detailed morphologic features of a glacier,” says Dr. Pascal Lee, a planetary scientist with the SETI Institute and the Mars Institute, and the lead author of the study. “Where some of the volcanic materials came in contact with glacier ice, chemical reactions would have taken place at the boundary between the two to form a hardened layer of sulfate salts,” says study co-author Sourabh Shubham, a doctoral student of geology at the University of Maryland, College Park.
Over time, erosion may have removed the volcanic materials, and a crusty layer of sulfates mirroring the glacier ice underneath became exposed, which would explain how a salt deposit is now visible.

Modern glacier remains found near Mars equator suggest water ice possibly present today at low latitudesIn a groundbreaking announcement at the 54th Lunar and Planetary Science Conference held in The Woodlands, Texas, scientists revealed the discovery of a relict glacier near the equator of Mars. Located in Eastern Noctis Labyrinthus at coordinates 7° 33' S, 93° 14' W, this finding is significant as it implies the presence of surface water ice on Mars in recent times, even near the equator. This discovery raises the possibility that ice may still exist at shallow depths in the area, which could have significant implications for future human exploration.
