January 27th marked the ”plugs-out” test, where the command/service module was operating with all three astronauts inside under its own power, an essential test for ensuring the spacecraft’s flight worthiness. There was no fuel, no cryogenics, and no known potential hazard to this test. All three astronauts entered the module in fully pressurized space suits, while the cabin was pressurized and filled with oxygen. The three hatches — the removable inner hatch, the hinged outer hatch, and then the outer hatch cover — were then externally installed. A minor communications problem arose in the late afternoon, causing the simulated countdown to stall at T-minus-10 minutes. What happened next was very fast.
At 6:30:54 PM, while the crew was running through their checklist a second time, a voltage spike was recorded. Ten seconds later, at 6:31:04, one of the astronauts exclaimed something inaudible, perhaps “Hey!” or “Fire,” a transmission that came through Grissom’s microphone. Two seconds later, at 6:31:06, Chaffee’s voice was clearly heard, “We’ve got a fire in the cockpit.” Seven seconds after that, at 6:31:13, an unidentifiable, heavily garbled voice yells “[…] bad fire […] get… out […] [open ‘er/burning] up,” followed by an end to the last transmission at 6:31:22. The last image that anyone reported seeing before the transmission ended was Ed White reaching for the inner hatch handle, as the flames swept from left to right across the monitor.
there are some things that are so beautifully crafted and connected to the the complicated and ever-changing web that is humanity that they leave you on the verge of tears. They don’t make you want to cry because they’re sad; they make you want to cry because they’re beautiful and sad and happy and hopeful and angry and bitter and sweet and a thousand other emotions you need to express but can’t articulate. As odd as World of Tomorrow is, it falls squarely in this streaming gem category.

Google and Apple are making great progress with self-driving cars, more than it was previously assumed. This is the assessment of Dieter Zetsche, Chief Executive of Daimler after a recent trip to Silicon Valley, one that was published in the German weekly Welt am Sonntag.

Audi has helped perfect the 3D printing process to create nearly the entire rover out of aluminum and titanium. It uses special channels to route wiring inside hollow structural components, something that couldn’t be done with a CNC process. “It’s not possible from the axis of freedom,” says Robert Böhme, CEO of PT Scientists. “The parts are like 1 millimeter thick.”
3D printing isn’t just going to contribute to the building of the rover. The team wants to create a 3D printer that can use lunar soil already chock full of aluminum, titanium, and magnesium to eventually create parts for other devices on the Moon. The theory is that it’s a lot easier to build something new on the Moon than it is to ship it there.

Made from steel and brass, this unusual prosthetic arm articulates in a number of ways. The elbow joint can be moved by releasing a spring, whereas the top joint of the wrist allows a degree of rotation and an up-and-down motion. The fingers can also curl up and straighten out. The leather upper arm piece is used to fix the prosthesis to the remaining upper arm.

Taking a yoga class for the first time can be intimidating, and learning the correct form for yoga positions while breathing properly is harder than it sounds.
Fashion tech company Wearable Experiments hopes to take the guesswork out of doing the perfect downward facing dog with its Nadi smart fitness pants.
The pants release gentle haptic vibrations throughout the fabric to guide the wearer to the correct form and posture for yoga poses.
