Why Spinning Was A Good Trick For America's First Space Launch

Vitenskap og teknologi

The first satellite launched into orbit by the US was Explorer 1 in 1958, this was launched using a rocket design developed by the US Army using mostly off the shelf rocket hardware. One of the most distinctive features of the rocket was the visibly spinning nose which contained the top 3 stages of the rocket. This design enabled the rapid development of the design and meant that in theory it could have launched a satellite into space before Sputnik were it not for the political problems associated with the Army team being lead by a former Nazi.
Spin stabilized rockets are actually a pretty common trick in space launches since it means you can forego thrust vectoring and other complicated guidance and control systems if you're happy to live with a satellite that can handle the spin.

    The antennas flexing and heating up is definitely the most amazing example of the conservation of energy and energy conversion that I have ever heard. You would have never thought that something could have slowed down due to radiating away heat but of course it does.

    Scott: Here's a question for you: Why were Atlas, Titan II, Jupiter and Thor used for evolutionary space vehicles after their conversion from military missiles to space boosters and Titan I was . . . not? Titan IIs were reconfigured for Titan IIIC and Titan IIIE and others. Yet the large numbers of Titan I missiles were scrapped. Was there no use for this particular vehicle dynamic?

    “Yo-yo de-spin,” or “ice dancer breakdown.” Separately, the fuel-spinning hack originated after a physicist wrecked shop at the local pool hall with some backspin-based hustlin’. Yeah, it cost a round of drinks and some pocket cash, but the space program got better. There’s that.

    The reason Sputnik was allowed (yes, allowed) to be launched first was to ensure that because the Russians couldn't complain about the overflights of their territories because when their satellites overflew the US, we didn't complain. It was a very clever move on the Eisenhower administration.

    That end over end flipping was first discovered by a Russian cosmonaut when he spun off a wingnut in his capsule, and noted that it kept flipping over. This was filmed, because at the time, nobody knew why. We know now, of course, but without space travel would we today? Maybe, but also, maybe not. Also, your video brings up another point. If we ever do have a battle in space, and it involves any kind of projectile, who knows where that projectile will end up. If you fire it and miss, who knows where it will end up. Reminds me of a short story about a US and Russian moon bases, and they keep skirmishing with each other. And both bases keep asking for more and more computers to be sent up. So the US fly's a general up to find out what's what. And the answer is (you guessed it), all the rifle rounds fired at the enemy went into low moon orbit, and they had to keep calculating all of the orbits of these projectiles, so that they didn't end up shot by their own spent ammo. Kind of brought home the silliness of fighting in space.

    @Mark Martin It was a story, and the people were shooting at each other parallel to the ground. So yeah, the moons gravity would have rendered those shots that missed irrelevant pretty quickly. But it was a fun story. The whole point was that war is stupid, and we needed to stop doing it. But human nature being what it is, i have no hope for it stopping any time soon.

    yo-yo despin works not only by increasing inertia tensor but also because wire is wound up around the stage, so when it gets unwound centrifugal force from weights is actually applied to the side of the stage (not center of mass). and it literally pulls the stage in the direction opposite to rotation. with only inertia tensor increase your can slow rotation (maybe by 3) but never stop it or go in reverse.

    I'm surprised I can't find it because I've seen videos showing it when talking of the space shuttle. But the shuttle launched spin satellites as well. However, I can't find a single launch of it. At least not easily. Google keeps mudding up the results thinking I mean spacex instead of space shuttle. Or it wants to show me a shuttle launch and not the satellite deploy. Edit: Or I'm terrible at searching. There was one with full video, but here is an example anyway. Same launch system from what I remember. And may even be the same launch, just recorded and stored later as they had gone out of range of live broadcast. noprojects.info/camera/video/tN1oZdSKiZ6Epns
