This is KI-0 ARNet control for the Colorado astronomy net continuing. We have been working this area with CHIRAD for almost 20 years without seeing anything from those depths, said Putsik. But once MRO achieved a very large role over the precise area, the team was able to look much deeper than the bright signal Marsis received. had detected a faint one. A different, very large roll observation of an adjacent area didn't detect a signal at all, suggesting something unique is causing a quirky radar signal at the exact spot Marsa saw a signal. The Lake House hypothesis generated lots of creative work, which is exactly what exciting scientific discoveries are supposed to do, said Morgan. And while this new data won't settle the debate, it makes it very hard to support the area of Elicit-Water Lake. Alternative explanations. Mars South Pole has an ice cap sitting atop heavily cratered terrain. And those radar images of the area below the ice show lots of peaks and valleys. Morgan said it's possible that the bright signal Mars is detected here may just be a rare, smooth area, an ancient lava flow, for example. While scientists are excited to use the Very Large Hole technique to re-examine other scientifically interesting regions of Mars, one such place is Medusae Fossae, a sprawling, geologic formation on Mars equator that produces little radar return. While some scientists have suggested It's composed of layers of volcanic ash. Others have suggested the layers may include heaps of ice deep within. If it's ice, that means there's lots of water resources near the Martian equator. Where you want to send humans, said Putsik, because the equator is exposed to more sunlight, it's more and ideal for astronauts to live and work.
