Those wheels you’re looking at are 0.75 millimeters thick. That’s half the thickness of a US dime. Each one was carved from a single block of aluminum, and NASA sent six of them to Mars knowing they’d eventually shred. Curiosity was built for a 2-year mission. It landed in August 2012, and by December that year NASA had already extended the mission indefinitely. Thirteen years and 35.5 kilometers later, the rover is still going, but the wheels started cracking just 14 months in. The damage came faster than anyone at JPL predicted. Sharp embedded rocks were punching straight through the skin between the treads. So NASA assembled a Wheel Wear Tiger Team (a crisis problem-solving tradition that goes back to Apollo 13) and got to work. In 2017, they uploaded a traction control algorithm from Earth that adjusts each wheel’s speed in real time based on the terrain, reducing force on the front wheels by 20%. They rerouted the rover to softer ground and started driving backward when possible, because pulling wheels over rocks produces less force than pushing them into rocks. The wildest part: if enough treads snap off, Curiosity is designed to find a sharp rock on Mars and use it to deliberately rip out the damaged inner section of its own wheel. JPL tested this on a replica rover and found Curiosity can keep driving on just the outer third. They predict this won’t be needed until around 2034. Every 1,000 meters, the rover pulls over and uses the camera on its robotic arm to photograph its own wheels so engineers on Earth can count every crack. Each wheel also has tiny holes that spell “JPL” in Morse code, which Curiosity uses to measure distance by photographing its own tracks in the dirt. These photos directly changed the next rover. When NASA built Perseverance, engineers 3D-printed about 70 different tread designs before landing on 48 curved treads instead of Curiosity’s 24, with thicker skin. They tested the new wheels over 60 kilometers and got zero damage by Curiosity’s original failure definition. “A boring graph with no data on it,” as one JPL engineer put it. A $2.5 billion machine doing self-surgery with rocks on another planet because the mission outlasted its design by 6x.

@0xtenthirtyone @AnishA_Moonka Are you just engagement baiting or do you actually believe that? The U.S. government is not giving away $2.5 billion, that isn't a thought based in reality.

@Seminar557 @AnishA_Moonka Hey retard it's simple math. $2.5 billion dollars for pictures of rocks is 2,500 millionaires we sacrificed for pictures of rocks. We could have just given 2,500 people a million dollars and it would have been more valuable than this stupid fucking Mars go kart

@Seminar557 @0xtenthirtyone @AnishA_Moonka he thinks that instead of doing the rover 2500 people could just be given a million dollars. I think he has some sort of developmental disorder.

@AnishA_Moonka Yeah but what have we got for that? A bunch of pictures of useless shit. We sacrificed 2,500 millionaires for pictures of rocks

@Abdullah_RM14 @fatiqmir @spectatorindex How would people possibly think Iran is gonna win this war? Basically all their senior leadership is dead, navy is destroyed, 100s of sites bombed.

BREAKING: Iran has demanded closure of US bases in the Gulf, end of all sanctions, end of Israeli campaign against Hezbollah and a framework that would allow it to collect fees from ships transiting through the Strait of Hormuz, as part of a response to Trump proposal, according to Wall Street Journal report.

@ProblemWright The game has been out for like 5 months, its not their fault you have the attention span of a 5 year old. Of course every month isn't going to have a crazy big update.

@arielhelwani You want a title fight over a clear number one contender when you just lost BAD to the last title challenger who lost to the champ Volk twice. Bark a little louder homie doubt it will help though. Unless mosvar gets injured even then it should be Murphy if that happens.

Jean Silva explains why he deserves the featherweight title shot over Movsar Evloev: “It’s really a dangerous game to let somebody like Movsar be a champion… I think he’s had like 10–11 cancellations at this point. I actually have all the components—the formula for what a UFC champion should be. This is more than just a fighting championship; whoever’s in front has to be able to bring the viewership. I’m the guy who actually brings it. I’m the name out there. There’s no other name that could do it as well as I can.”

*UPDATED* How to easily get PVE ONLY lobbies in Arc Raiders! 🙌 - Play 4-6 matches without harming a raider - You can ONLY shoot Arcs - Let other raiders kill you no matter what - Killing or downing a raider immediately breaks the streak SAVE FOR LATER 🔥

@J0RDANXI @ChampRDS My problem is it wasn't a 30-27, and it definitely wasn't a unanimous 30-27. Politics getting in the way of judging ruins the UFC.

@Seminar557 @ChampRDS Look at their stats riley had the more accurate output and heavier shots r1 I’ll say aswell should realistically win because of the mix in control time and strikes but 2 and 3 Riley was landing heavy shots. Aswell tanking them just made it seem insignificant.

@macdemarcoluvrr @drunkatweighins @ChampRDS 1 was Aswell, 2 could have gone either way, and 3 was Riley. My problem is that it was not 30-27, and definitely not a unanimous one. I 100% put it up to Riley being a popular brit and him being in London, I hate when politics get in the way of scoring.

@Seminar557 @drunkatweighins @ChampRDS hahahahahah use your brain again man, the first round was the only round were i 100% wouldn’t give it riley even tho he won the last 2 mins of the round. the fight only looked somewhat competitive because of how tough aswell is. rewatch the fight and you’ll realise riley won easy

@Seminar557 @drunkatweighins @ChampRDS bro you do realise the stats shown mid fight aren’t 100% accurate???🤣🤣 + you put up a photo of halfway through the round, where the last 2 and a half minutes luke riley battered aswell and aswell done literally nothing? use your brain man
