NASA’s outdated however nonetheless kickin’ Interest rover drove over a boulder, which crumbled to expose yellow sulfur crystals.
Rocks product of natural sulfur have by no means been noticed earlier than at the Crimson Planet, and scientists say the stipulations by which such crystals shape aren’t related to the positioning the rover used to be exploring.
Since October 2023, the rover has been exploring a area of Mars wealthy with sulfates, a type of salt that incorporates sulfur and paperwork as water evaporates. However the place previous detections had been of minerals consisting of a mixture of sulfur and different fabrics, the rock Interest not too long ago cracked open is product of elemental, or natural, sulfur.
“It paperwork in just a slender vary of stipulations that scientists haven’t related to the historical past of this location,” a NASA spokesperson mentioned.
“And Interest discovered numerous it—a complete box of vibrant rocks that glance very similar to the only the rover overwhelmed.”
Interest made the invention whilst off-roading inside of Gediz Vallis channel, a groove that winds down a part of the 3-mile-tall (5-kilometre-tall) Mount Sharp, the bottom of which the rover has been ascending since 2014.
NASA says it isn’t transparent what dating, if any, the fundamental sulfur has to different sulfur-based minerals within the space.
Interest’s mission scientist, Ashwin Vasavada of NASA’s Jet Propulsion Laboratory, in comparison discovering a box of stones product of natural sulfur to “discovering an oasis within the barren region.”

“It shouldn’t be there, so now we have now to provide an explanation for it. Finding abnormal and sudden issues is what makes planetary exploration so thrilling,” mentioned Vasavada.
The Gentleman Report studies that Vasavada and the staff have noticed proof of vibrant white calcium sulfate, sometimes called gypsum, inside of cracks at the Martian floor which can be necessarily hard-water deposits left in the back of by means of historical groundwater flows.

The mineral itself is not any crimson diamond: sulfur is the 10th maximum not unusual component by means of mass within the universe, and the 5th maximum not unusual on Earth. In different places within the sun gadget, it can be provide close to the Lunar crater Aristarchus, whilst the unique colours of Jupiter’s monumental satellite tv for pc Io are believed to consequence from varieties of molten, cast, and gaseous sulfur.
Fortunately, whilst folks affiliate sulfur with the scent of rotten eggs, the results of hydrogen sulfide gasoline, NASA confirms that elemental sulfur is odorless.
