Aliens aren’t terraforming Mars, however considered one of NASA‘s rovers simply discovered one thing with a wierd texture which may entice a cauliflower lover to do a double-take.
Curiosity, a Mini Cooper-sized lab on wheels, was ambling over rugged terrain a number of days in the past this March when its navigation digicam noticed some Martian rocks not like any others. The scientists main the rover’s expedition say they’ve by no means seen something fairly like this on the Pink Planet.
“Oh my glob,” the anthropomorphic Curiosity account posted on X. “What are these lumpy rocks?”
However Curiosity wasn’t the one one with a geological thriller. On the identical time, roughly 2,300 miles away on the opposite aspect of the planet, Perseverance discovered bumpy rocks of a distinct form, calling to thoughts the well-known “Martian blueberries” found by the Alternative rover in 2004.

Since its mission launched in 2011, Curiosity has traveled about 352,000,020 miles: some 352 million whizzing by way of house and one other 20 over the rusty-dusty terrain. Proper now it is on its technique to an unexplored a part of Gale Crater, known as a “boxwork” area, which probably necessitated heat groundwater to kind eons in the past.
Usually outshined by its youthful twin rover Perseverance, Curiosity stole again the limelight earlier this week for a monumental discovery primarily based on considered one of its rock samples. Inside it, researchers detected the most important natural molecules but on Mars, suggesting the chemistry wanted for all times might have progressed additional on the Pink Planet than as soon as thought. The molecules, which include lengthy chains of carbon atoms, may very well be items of fatty acids, key substances for Earth life.
Although the natural molecule discover, revealed within the Proceedings of the Nationwide Academy of Sciences on Monday, is not proof of life, it does encourage scientists that different extra advanced molecules linked to life might nonetheless be on Mars. Beforehand, researchers have been skeptical over whether or not such proof might stay on the planet after hundreds of thousands of years of radiation and environmental modifications.
Mashable Mild Pace
Suffice to say, Curiosity is to not be underestimated in its scientific worth. The group gave Curiosity’s new rocks official names — Manzana Creek and Palo Comado — and took photos for the file. The leftward rock within the picture on the high of this story has jagged, vertical surfaces and “a lot of crazy rough texture,” in line with the mission journal.

“The rocks were shaped by a combination of wind and water over time, resulting in the cool textures we see today,” Abigail Fraeman, Curiosity’s deputy undertaking scientist, advised Mashable.
Perseverance’s bumpy rock, however, appears to be like slightly extra like a cluster of miniature peas than cauliflower. It is lined in millimeter-scale beads, some pierced with tiny pinholes. The rover discovered the rock, formally dubbed St. Pauls Bay, across the rim of Jezero Crater.
And it appears each rovers’ sightings have flummoxed their people.
“What quirk of geology could produce these strange shapes?” wrote Alex Jones, a researcher engaged on the Mars 2020 mission group, in a weblog publish.

Spherical options can kind on rocks when water flows by way of them, creating concretions of minerals over time. However they’ll additionally kind in different methods, like in volcanic eruptions and meteorite strikes. When droplets of molten rock are thrown into the air by volcanoes or impacts, they cool as they journey, hardening in little balls.
Scientists will proceed learning the rocks utilizing the instruments accessible to them on the rovers, however such finds reinforce the will for NASA to convey samples again to Earth for extra rigorous research.
Proper now the house company is attempting to determine find out how to save its Mars Pattern Return mission, the plan to fly residence bits of rock, mud, and air collected by Perseverance. NASA will spend the following 12 months engaged on engineering plans for two potential new approaches which can be thought of simpler and costly.
