Space

+ - Yuri's Night: April 12, 1961 first human spaceflight->

Submitted by k6mfw
k6mfw (1182893) writes "April 12, 1961 USSR launches Yuri Gagarin making the first human orbital spaceflight. This is when both countries USA and USSR got real serious on developing human spaceflight capabilities. April 12, 1981 USA launches Space Shuttle making the first reusable spacecraft flight but for nearly 20 years it had no place to go. But the Russians have a space station so both countries teamed up on International Space Station. April 12 becomes the perfect date to celebrate space, technology, art, sciences, and engineering."

+ - Military surplus a bonanza for law enforcement->

Submitted by k6mfw
k6mfw (1182893) writes "from the article: "San Francisco may be known for antiwar movements and peace rallies, but when local law enforcement agencies needed help with supplies, they've turned to the U.S. military."
"A total of 163,344 new and used items valued at $26.2 million — from bath mats acquired by the sheriff of Sonoma County to a full-tracked tank for rural San Joaquin County — were transferred last year to state and local agencies.""

+ - Cars: The Next Victims of Cyberattacks->

Submitted by k6mfw
k6mfw (1182893) writes "From IEEE Spectrum, http://spectrum.ieee.org/tech-talk/computing/embedded-systems/cars-the-next-victims-of-cyberattacks, "Every year, automakers endow vehicles with more brainpower. But the computer hardware engineered to keep cars from crashing or to keep drivers entertained might soon be co-opted by criminals intent on attacking a single driver or causing widespread havoc. Several research groups have independently demonstrated smart cars’ vulnerability to cyberattacks. Security firm McAfee reported an incident where a disgruntled former employee at a Texas car dealership used a remote car deactivation system to simultaneously shut off the engines of 100 vehicles."

Personally I don't like the trends of car design, i.e. button to start/stop engine that is a computer input instead of direct on/off of ignition system. I also don't like trends towards less visibility (shorter windows) which lead to higher chances of collisions. And uni-body construction, a basic fender bender may be extremely expensive to repair."

âNASA engineers have installed a camera on the external fuel tank (ET) which will transmit live pictures of its destructive burn up on re-entry. The live FM transmitted signal will be on 2272.5 MHz at 10 watts. The camera captures images at (NTSC) frame rate of 30 frames per second and will burn up over the Pacifc Ocean over the east coast of New Zealand, entry interface (EI) will begin at 400,000 ft over southern Australia and can be seen with the naked eye.”

“We have not yet been able to analytically confirm if a plasma blackout condition will present a TV reception problem prior to breakup.”

STS-135: Tank Camera modification aimed at filming footage of ET-138’s death

“The prospect of footage from the tank itself — as it vents and starts to disintegrate — on the final ever shuttle mission, may not be up to the high standards of the Soyuz ‘Flyabout’ footage of Endeavour and the ISS, but it would provide a potentially stunning viewpoint of the final Shuttle ET, prior to its demise.”"
