NASA's Mars rover Curiosity continues to move forward with assessment and recovery from a memory glitch that affected the rover's A-side computer. Curiosity has two computers that are redundant of one another. The rover is currently operating using the B-side computer, which is operating as expected. Over the weekend, Curiosity's mission operations team continued testing and assessing the A-side computer's memory.
NASA's Wide-field Infrared Survey Explorer (WISE) has discovered a pair of stars that has taken over the title for the third-closest star system to the sun. The duo is the closest star system discovered since 1916. Both stars in the new binary system are "brown dwarfs," which are stars that are too small in mass to ever become hot enough to ignite hydrogen fusion. As a result, they are very cool and dim, resembling a giant planet like Jupiter more than a bright star like the sun.
It's difficult if not downright impossible to keep up with the amazing developments that have overtaken the avionics world.... barely a day goes past without a new announcement promising here-to-fore unparalleled capabilities and gadgetry. And, surprisingly, the Sport Aviation segment is leading the way in a number of these new technological marvels. Advanced Flight Systems has been particularly noticeable in this market segment and their humongous AF-5800 is hard to ignore.
Almost Ready To Leap Tall Buildings At A Single Bound
On Thursday, March 7, 2013, SpaceX’s Grasshopper doubled its highest leap to date to rise 24 stories or 262.8 feet, hovering for approximately 34 seconds and landing safely using closed loop thrust vector and throttle control. Grasshopper touched down with its most accurate precision thus far on the centermost part of the launch pad.
