New Map Reveals Ice Deposits on Mars for Future Astronauts
A new map of subsurface water on Mars has been released by the NASA-funded Subsurface Water Ice Mapping project (SWIM), bringing hope to the possibility of water resources for future astronauts. The map, which is being hailed as the “most detailed” since the project’s inception in 2017, identifies regions on the Red Planet where ice may be buried beneath the surface.
SWIM utilized data from various NASA missions, including the Mars Reconnaissance Orbiter (MRO), Mars Odyssey, and the Mars Global Surveyor, to pinpoint the possible locations of subsurface ice on Mars. The latest map benefits from the high-resolution cameras on board MRO, providing a more detailed view of the water than previous versions that relied on lower-resolution instruments.
One notable discovery made by SWIM was a 492-foot-wide (150-meter-wide) impact crater containing what NASA describes as a “motherlode of ice that had been hiding beneath the surface.” This finding highlights the potential significance of the new map in uncovering hidden caches of frozen water.
According to NASA, the mid-latitudes of Mars, where the spacecraft identified subsurface frozen water, are considered ideal for future missions. The region’s thicker atmosphere allows spacecraft to slow down more easily during descent, making it an attractive landing spot for astronauts. The southernmost edge of the northern mid-latitudes region, in particular, offers a strategic location as it is close enough to access the buried ice but still within reach of the equator for slightly warmer weather.
Sydney Do, the SWIM project manager at NASA’s Jet Propulsion Laboratory, emphasized the importance of proximity to the equator, stating, “The less energy you have to expend on keeping astronauts and their supporting equipment warm, the more you have for other things they’ll need.”
While the Martian poles are known to contain ice, the extreme cold makes them inhospitable for long-duration human missions. The subsurface ice, however, offers a more viable resource that can be drilled and extracted for various uses, such as drinking water and rocket fuel.
The discovery of buried ice not only has practical implications for future astronauts but also allows scientists to gain insights into Mars’ climate over time. By understanding the distribution and variations of subsurface ice, researchers hope to uncover new hypotheses about the planet’s climatic history.
The unveiling of this new map represents a significant step forward in the quest for human exploration of Mars. With the potential for accessing water resources beneath the Martian surface, the dream of sustained missions and eventual colonization becomes more realistic. As NASA continues to unravel the mysteries of the Red Planet, the prospect of life beyond Earth appears to be within our grasp.
