Because you can. Ahem. And so for the time being, I'll be spending less time staring at my monitor and more time resting my eyes. The Newsletter will still arrive as usual each week, but it won't be as huge. That said, it will contain a few extra goodies to make up for it, by way of curious finds. And speaking of finding stuff...."On Thursday, March 7, 2013, SpaceX's Grasshopper doubled its highest leap to date to rise 24 stories or 80.1 meters (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. At touchdown, the thrust to weight ratio of the vehicle was greater than one, proving a key landing algorithm for Falcon 9. The test was completed at SpaceX's rocket development facility in McGregor, Texas." - by Neatorama
