Скачать или смотреть Mars ‘Lake’ Mystery Solved? MRO Discovers Rock Beneath South Pole Ice

Did Mars really have a hidden underground lake at its south pole, or was it all a cosmic illusion?
In this video, we break down the new analysis from NASA’s Mars Reconnaissance Orbiter (MRO) that challenges the famous 2018 “subterranean lake” claim and reveals that the bright radar signal under the south pole is most likely solid rock or compacted sediments beneath thick ice – not a liquid water lake.
You’ll learn:
How the original 2018 MARSIS radar data led scientists to suspect a buried liquid lake under Mars’ south polar ice cap.
Why liquid water under the ice was so exciting for the search for life and future human missions.
How NASA’s SHARAD radar on MRO returned to the exact same region and used a special “very large roll” maneuver, rotating the spacecraft about 120° to see much deeper beneath the ice.
What the new SHARAD data show: no bright echo like before and a subsurface that looks consistent with rock or dense sediments instead of a lake.
Why this was not a “mistake” but an example of how science advances by testing, correcting, and refining earlier interpretations.
We’ll also explore what this means for the future of Mars exploration:
How the improved radar techniques are now being used to hunt for accessible ice that astronauts could actually use for water, oxygen, and crops.
The SWIM (Subsurface Water Ice Mapping) project, which combines data from Mars Reconnaissance Orbiter, Odyssey, and Mars Global Surveyor to build a high‑precision map of shallow ice across Mars.
Key regions like Arcadia Planitia and Deuteronilus Mensae, where near‑surface ice could support future bases.
New targets such as Medusae Fossae, an enormous equatorial formation that may hide volcanic sediments or even huge buried ice deposits.
How international plans like the Mars Ice Mapper mission aim to search for usable ice with extreme precision.
