NASAs rovers just found similar gnarly rocks on opposite sides of Mars
Aliens aren’t terraforming Mars, but one of NASA‘s rovers just found something with a strange texture that might entice a cauliflower lover to do a double-take.
Curiosity, a Mini Cooper-sized lab on wheels, was ambling over rugged terrain a few days ago this March when its navigation camera spotted some Martian rocks unlike any others. The scientists leading the rover’s expedition say they’ve never seen anything quite like this on the Red Planet.
“Oh my glob,” the anthropomorphic Curiosity account posted on X. “What are these lumpy rocks?”
But Curiosity wasn’t the only one with a geological mystery. At the same time, roughly 2,300 miles away on the other side of the planet, Perseverance found bumpy rocks of a different kind, calling to mind the famous “Martian blueberries” discovered by the Opportunity rover in 2004.

Since its mission launched in 2011, Curiosity has traveled about 352,000,020 miles: some 352 million whizzing through space and another 20 over the rusty-dusty terrain. Right now it’s on its way to an unexplored part of Gale Crater, called a “boxwork” region, which likely necessitated warm groundwater to form eons ago.
Often outshined by its younger twin rover Perseverance, Curiosity stole back the limelight earlier this week for a monumental discovery based on one of its rock samples. Within it, researchers detected the largest organic molecules yet on Mars, suggesting the chemistry needed for life may have progressed further on the Red Planet than once thought. The molecules, which contain long chains of carbon atoms, could be pieces of fatty acids, key ingredients for Earth life.
Though the organic molecule find, published in the Proceedings of the National Academy of Sciences on Monday, isn’t proof of life, it does encourage scientists that other more complex molecules linked to life could still be on Mars. Previously, researchers have been skeptical over whether such evidence could remain on the planet after millions of years of radiation and environmental changes.

Suffice to say, Curiosity is not to be underestimated in its scientific value. The team gave Curiosity’s new rocks official names — Manzana Creek and Palo Comado — and took pictures for the record. The leftward rock in the image at the top of this story has jagged, vertical surfaces and “a lot of crazy rough texture,” according to 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 project scientist, told Mashable.
Perseverance’s bumpy rock, on the other hand, looks a little more like a cluster of miniature peas than cauliflower. It’s covered in millimeter-scale beads, some pierced with tiny pinholes. The rover found the rock, officially dubbed St. Pauls Bay, around the rim of Jezero Crater.
And it seems both rovers’ sightings have flummoxed their humans.
“What quirk of geology could produce these strange shapes?” wrote Alex Jones, a researcher working on the Mars 2020 mission team, in a blog post.

Spherical features can form on rocks when water flows through them, creating concretions of minerals over time. But they can also form in other ways, 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 travel, hardening in little balls.
Scientists will continue studying the rocks using the tools available to them on the rovers, but such finds reinforce the desire for NASA to bring samples back to Earth for more rigorous studies.
Right now the space agency is trying to figure out how to save its Mars Sample Return mission, the plan to fly home bits of rock, dust, and air collected by Perseverance. NASA will spend the next year working on engineering plans for two potential new approaches that are considered less complicated and expensive.

Not many people consider the chore of mowing the lawn to be enjoyable. It’s a task we often hand off to the neighborhood kids or a professional landscaping crew. But if you’d rather take matters into your own hands, we have a great solution these days. Plus, an affordable model is on sale.
As of July 21, the Ecovacs Goat 01000 RTK robot lawn mower is on sale for $698.99 at Amazon, marked down from the list price of $999.99. That winds up being a savings of $301 from a 30% discount.
By now you’ve probably seen a robot lawn mower rolling around someone’s yard, but it’s still an abnormal sight. Just like the rollout of robot vacuums, we’ll slowly start to see more and more robots take over mowing the lawn. As someone with allergies, I’m totally cool with never touching a lawn mower ever again.
The Ecovacs Goat 01000 is designed to maintain lawns that span up to 0.25 acres in size. You don’t need to worry about a wire perimeter because it maps your yard and stays on course thanks to LiDAR RTK navigation that even works in the shade or under trees. It can even avoid obstacles when mowing in dark conditions.

The small mower body that measures 2.3 feet means it can mow in tight areas like between raised vegetable beds or small walkways. Plus, it has an IPX6 waterproof design. You get to decide on your ideal cutting length between 1.2 and 3.2 inches.
Today’s Amazon deal on the Ecovacs Goat 01000 applies to the robot mower with a care kit which includes 36 blades and an RTK AC adapter. Since the mower and the care kit are on sale for under $700, today is a great day to wave goodbye to the heavy and loud push mower and make the upgrade. Spend the rest of summer perfecting homemade slushies instead of doing yardwork.

I used to have a Bissell Little Green machine, and it worked right up until I poured liquid into the wrong compartment. But before my little mishap, this little thing was a lifesaver (I seldom use that word, but in this case, it’s true). With two beagles running around my apartment, having a carpet cleaner is a necessity.
And right now, you can get your own Bissell Little Green Max Pet SmartMix carpet cleaner for $119.99, down from $159.99. That’s a 25% discount or $40 in savings.

It comes with a specialized Pet Hair Removal Tool designed to grab embedded fur and debris from your upholstery, and once you’re done scrubbing, the Self-Cleaning Tough Stain Tool rinses out the leftover dirt and residue from the hose with the touch of a button (my machine didn’t have that feature).
Another major upgrade on this specific model is the SmartMix Technology, which automatically mixes the water and cleaning formula together for you so you don’t have to measure anything. Just be sure you pour it into the correct tank!
