The Curiosity rover broke free from the "captivity" it had found itself in just a few days earlier – on April 25th, after drilling into a rock, it literally "stuck" to the drill bit and refused to release. Instead of breaking apart during the drilling, the rock was pulled out of the surface in one piece and remained hanging on the drill bit as the robotic arm began to lift. And it wasn't just a small fragment. NASA estimates the rock was about half a meter wide, about 15 cm thick, and weighed about 13 kg. At first, the scientists tried to dislodge it by vibrating the drill, hoping the rock would shake off on its own. This didn't work. A few days later, they repositioned the robotic arm and turned on the vibration again. Sand fell off the rock, but it remained attached. Then, on May 1st, the engineers used a more aggressive sequence of actions: they tilted the drill bit more sharply, began rotating it, and simultaneously increased the vibration. It worked – on the first try, the stone finally broke loose, fell onto the surface of Mars and split.

NEW: Drilling contractor accidentally punched a hole in the Queens Midtown Tunnel causing water from the East River to spew into the tunnel. The incident forced officials to close the tunnel for nearly an hour. According to MTA CEO Janno Lieber, a private contractor was "drilling to find pylons for the East River greenway" when the incident happened. "We determined it was a drilling contractor who drilled about a 2.5-inch hole through the cast iron liner," said the president of MTA Bridges and Tunnels Cathy Sheridan.

Is Static Drilling the Kata of Jiu Jitsu? I have never done Kata, so I do not have a strong opinion on its value. It does look boring to me, though. Static drilling has some value, but not as much as live drills using the Constraints-Led Approach (CLA). If someone shows me a new move or solution, I will statically drill it 2 or 3 times. Then I will try to incorporate it in some live training. Static drilling makes up less than 1% of my training now. CLA will build your grappling skills faster and is a lot more fun.

No damages to the Florence Ya’ll Water tower, crews say. The power is out and the pump feeding the tower has stopped working. Gravity is letting the water out as it’s designed to do. A worker is trying to shut off the valve for now until the power returns. WLWT

"South West Water is due to be sentenced today after admitting supplying water unfit for human consumption" A YouGov poll last month showed that 82% want water in public ownership, but the govt won't do it because they're on the side of the profiteers, not us.

One detail I *really* enjoy while coaches are running a practice: The top gradient and button tint smoothly adapt to the drill category's color when the next drill comes up. This thing is turning out sexy, can't wait to ship ✨

Coffee with mineral water becomes a viral trend The new drink — coffee with mineral water — has quickly gained popularity online, with claims that it boosts energy more effectively than any energy drink. The secret is that the mineral water helps caffeine absorb faster, while also replenishing magnesium and calcium lost due to coffee. The recipe is simple: a glass with ice, mineral water, a shot of espresso, a pinch of salt, and a bit of lime juice.

UPDATE: All heavy duty pumps, and associated system components at the Katosi water works are in action. We are pushing water to Kampala at FULL BLAST, and some customers have started receiving water. For those without water, help is on the way. We are rigorously charging the network with water in a bid to serve you in the shortest time possible. #waterman Dr. Silver Mugisha

Philadelphia Eagles Tackling Drill!🚨🚨🚨 Philadelphia Eagles are gliding their hands through the bags to emphasize staying low while gathering their feet before contact! I’ve actually never seen this drill before but I absolutely love the idea behind this drill! More and more teams should start using this drill to make sure that the players’ pad level is staying low throughout the whole drill! Philadelphia Eagles

Imagine this: You’ve paid to drill a 100m borehole. The rig arrives, the noise starts, and the dust settles. But when they pull the rods out? The hole is bone dry. 🤦🏿‍♂️ Now you're staring at a bill for a dry hole: First 40m (fixed fee): $850 Next 60m ($23/m): $1,380 Total Wasted: $2,230.00 💸 That is over two thousand dollars of your hard-earned money buried in the ground all because someone guessed where to drill. In this economy, you cannot afford to waste that kind of money. Don't drill blind. We use professional mapping to find the water before the rig arrives. We make sure you only drill once

In the first video, people in Donetsk are seen greeting a water tanker. In the second video, during the rain, people try to collect at least a drop of water because the water pipeline from the Siverskyi Donets was destroyed by the Russians. When Donetsk was not occupied by Russia, the city hosted the European Football Championship, as well as concerts by Rihanna and Beyoncé. Now, there is no more running water in the city. According to the schedule, water only appears in taps once every three days, and even then it doesn’t reach every household, so water has to be delivered by tankers, with long queues forming for it. People use plastic bags as toilets, and this filth spreads everywhere. This is happening not only in Donetsk - water is supplied once every two days in a number of other cities, including Mariupol. This is how Russia 'liberated' Donbas. Why is this happening? In the past three and a half years - since Russia launched its full-scale invasion of Ukraine in February 2022 - reservoirs in Donetsk Oblast have significantly dried up. The water supply system from the Siverskyi Donets River was destroyed. The region’s reservoirs and underground water sources are not enough to meet the needs of the population, in part due to the extensive network of coal mines. When the self-proclaimed “DPR” and “LPR” were created in 2014, Ukraine did not cut off this water channel, as it was still supplying water to Mariupol, which remained under Ukrainian control. But at the start of the Russian invasion in February 2022, the situation changed: the Russian army, during its offensive, destroyed a unique hydraulic structure that had supplied the region’s largest cities with water. The Russian authorities decided to build a new canal - the Don–Donbas canal - which was supposed to begin in the Rostov-on-Don area. It soon became clear that the new water pipeline, first of all, could not provide the region with the necessary amount of water, and second, it was built with numerous violations, with a large portion of the budget embezzled during construction. Crimea is also suffering from a water shortage, and the situation is worsening. One of the reasons why Russia is striving to seize southern Ukraine is that it sees this as a way to "solve the water issue" for the occupied territories.
