Swedish Engineer's RC Plane Gets a Balloon Lift To Space

      My intuition says if you can/do get there using the atmosphere to generate lift (planes & balloons), it's clearly not space.

      The typical distinction is more arguable but, in my opinion, a reasonable principle:
      If the atmospheric drag at a given altitudes orbital velocity is too high to allow you to orbit, it's not space. If the atmosphere is thin enough to allow you to orbit, it's space.

      That's a somewhat fuzzy definition, but that's appropriate; "the edge of space" is a fuzzy concept. But: it's a fuzzy line whose bottom is maybe as low as 100Km up (really, orbits below twice that are impractical). 33 Km isn't space or near it; It's the stratosphere.

      I'm not sure where the uncertainty in your 50% chance of making orbit comes in, but if that's your line, you're arguing for 100Km, minimum.

      The speed you need to go sideways to orbit goes down as you go higher. The speed you need to go sideways to stay up via aerodynamic lift goes up as you go higher (and air pressure goes down). The crossover, where generating enough lift would require going faster than orbital speed is the Karman line. Above that, you can't stay up via aerodynamic lift, you must orbit or come down.

      Atmospheric drag makes it impractical to approach orbital speed at less than about 200Km, but in theory, if you had a big enough engine and streamlined enough plane, you could fly along at less than orbital speed up to about 100Km up; beyond that, you must stay up by orbiting: it's impossible by flying.

      WTF? Balloon grade helium is still 95% helium, which is about on par with how it comes out when separated and crudely purified from natural gas. 22k gold is less pure than that, but would you consider that not worth saving? And all you need to do with low grade helium is run it over activated charcoal to get 99.99+% pure helium.

    Funny how we call helium a scarce resource... it's the 2nd most common element in the Universe.

    In the universe, yes. On Earth, no. All the helium on Earth has been here from the beginning, and no process on Earth is creating more. Once it's released in to the atmosphere, it's gone.

    I'm always envious of stuff like this. Where I live (southwestern British Columbia, Canada), it would be very difficult to retrieve a payload that came down 100 km away, in just about any direction. A steerable RC glider is an option I've thought about. Live video, GPS and telemetry would make me even more motivated to get the aircraft back.

  23. Nice idea and important step by Anonymous Coward · · Score: 0

    Launching an aircraft with a balloon and having it fly back is a nice important step, but what I would like to see is an Arduino controlled aircraft (even a glider) which has a GPS and camera, and it records its progress (1 picture per second), and when the balloon pops, the plane is released (just like this), but then the plane (or glider) tries to fly back to a pre-set coordinate (using the arduino for GPS and for robot flight /control over the gliders control surfaces). That way instead of just following a beacon back to the crash/landing location, the plane at least tries to go back to a set location. A *really* cool feature would be if it can't make it back to the ideal home location (not enough altitude left), at least it could find the optimal landing location (like between the trees and the highway in the video) instead of in the trees. The second is optomistic. The first is do-able, and would save a lot of recovery time (and potential for landing in a very difficult recovery location).

  24. No control in the thin air by Geoffrey.landis · · Score: 1

    The balloon launch requires that you notify the FAA.

    Looking at the video, the release is around 3:00, and at that point the vehicle goes into a spin. The video is cut after a few seconds of spin, and resumes when he finally pulls out, but it looks like he didn't regain control until it lost a lot of altitude and got into much denser air.

    There's a pretty obvious element the gp is ignoring here, as well. Hobby weather balloon projects couldn't possibly account for more than the very tiniest fraction of waste plastic that ends up in the ocean in the first place. There are very few of them, most of them fall on dry ground, and a fair percentage of those are probably recovered since that's a primary goal in these projects (you want your footage, flight data, etc).

    I'm all for being careful about where things go, but in these cases I think we'd have to be more concerned about a popped balloon and cooler falling on moving traffic. I can't think of any way this ends up being a serious threat to marine life.
