ESOX X2 Unmanned Ground Vehicle UGV
Soldiers still burn hours and calories moving water, ammunition, and radios across ground that wrecks ordinary trucks. Pack animals once filled that gap. Conventional electric robots often stall in the same mud, sand, snow, and rubble because their motors sit in the middle of the chassis and feed torque through gearboxes and shafts that lose grip the moment the surface turns ugly. ESOX Group finished a compact uncrewed platform, called the X2, this summer that tries to skip that failure.

Polymatt NASA Heat Shield Recreation Crack
Chunks of Orion’s Avcoat came off Artemis I after splashdown, and the scare was real enough that a crewed flight sat in the hangar while investigators spent two years on the cause. Reentry heat itself was not the surprise. Skip entry was. Orion dipped, lifted, then came back in so the peak load would be gentler. That quieter stretch of heating left the outer char less open than a hard, continuous burn. Pyrolysis gases had nowhere to go, pressure rose inside the char, and pieces of the shield broke free. Ground tests that only hammered the material with a short, fierce pulse never showed it.

Travis Pastrana McMurtry Speirling Test Drive

Travis Pastrana has jumped from a plane with no parachute, landed the first double backflip on a motorcycle, collected 11 X Games gold medals, and raced the Daytona 500. On a day at Dunsfold Aerodrome in England, the same airfield used as the old Top Gear test track, he still found something that reset his scale. He climbed into a McMurtry Spéirling prototype and later said he had gone faster than in any vehicle of his life.
