    Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. While there might not quite have been the epic science news that we had last week, that doesn't mean that there isn't plenty going on in the world of Alt. In this installment we get to see how CERN tricks out its offices, how one farmer tries to keep his flock, and learn about how the military will be high-tailing around the planet in just a few years. This is alt-week.

  • NASA budgets $15 million for hypersonic flight

    You're probably familiar with supersonic planes like the SR-71 Blackbird pictured above, which managed to fly at over three times the speed of sound, but imagine this: NASA set aside $15 million to develop a hypersonic plane that could exit our atmosphere at speeds between Mach 5 and Mach 20. The US space agency's not expecting to build it quite that cheaply, of course, and it's not holding out hope for a contractor to build the entire plane just yet -- the organization intends to fund some sixteen smaller science and engineering projects (ranging from "how to build a Mach 8+ engine" to "predicting hypersonic fluid dynamics") and letting would-be government contractors pick and choose. Know how to quantify baseline turbulent aeroheating uncertainty in a hypersonic environment? You've got until November 23rd to get your proposal in. Update: As some have pointed out in comments, hypersonic flight isn't unprecedented -- NASA spent eighteen years developing and testing the X-15 space plane starting in 1951, which reached Mach 6.7 using a rocket engine.
