NASA scientists have made a stunning discovery on Mars after a rover fired a laser at a rock and uncovered proof of gemstone-like minerals hidden inside. The invention was made by NASA’s Perseverance rover, which is exploring Jezero Crater on the Crimson Planet. Scientists used the rover’s laser instrument to look at a rock and located unusually excessive quantities of minerals which might be linked to gem stones on Earth.
Researchers have been stunned as a result of the minerals appeared in a location the place they weren’t anticipated. The discovering means that Mars could have skilled extra complicated geological processes than scientists beforehand believed.
“Very unexpectedly,” wrote a crew led by geochemist Ann Ollila of Los Alamos Nationwide Laboratory in a conference abstract, “SuperCam’s TRL evaluation of three plagioclase-rich float rocks within the crater rim have been discovered to exhibit clear signatures of chromium-bearing corundum.”
In line with the analysis crew, the minerals possible shaped when sizzling water moved by means of cracks within the rock hundreds of thousands and even billions of years in the past. On Earth, related situations might help create crystals and gem stones. The presence of those minerals supplies additional proof that water as soon as performed an essential function in shaping the Martian panorama.
Scientists say the invention may assist them higher perceive the planet’s historical atmosphere and whether or not situations could as soon as have been appropriate for microbial life. The minerals additionally supply clues in regards to the historical past of volcanic exercise and the motion of water beneath the Martian floor.
Perseverance continues to gather samples that might at some point be returned to Earth for detailed examine. Researchers hope these samples will reveal much more about Mars and its lengthy geological historical past.
The surprising discover highlights how a lot there may be nonetheless to study in regards to the Crimson Planet and reveals that even ordinary-looking rocks can maintain exceptional secrets and techniques.
The findings have been detailed in Geophysical Research Letters.
