DailyDirt: Actually Getting People Into Space...

from the urls-we-dig-up dept

There are only a handful of vehicles that have launched people into space (or even just provided shelter) for space-faring people. A few more ships and space stations would be nice to see, and there are a few in various stages development (unfunded proposals, ahem). If you're interested in people (not just robots) exploring outer space, here are just a few links on some of the ships that might transport more folks to at least the edge of space. After you've finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

–The Techdirt Team

    > Not only will this mean you need a significantly higher speed than would be need on an airless planet with that same gravity, but there will be enormous heat problems

    An example of this: The 900-kilogram steel plate cap for the test shaft of the Pascal-B nuclear test.
    Before the test, experimental designer Dr. Brownlee had estimated that the nuclear explosion, combined with the specific design of the shaft, would accelerate the plate to approximately six times escape velocity. The plate was never found, but Dr. Brownlee believes that the plate never left the atmosphere, as it may even have been vaporized by compression heating of the atmosphere due to its high speed.

    Granted, we now know much more about meteorites, including that the heat of re-entry will still have them arriving at the ground with a cold interior. Ablation can remove heat, which is how the fibreglass Apollo heat shield worked, and a Russian wooden heat shield.

    If any bit of it cleared the atmosphere, it would mean that America put an object into solar orbit a couple months before Sputnik reached earth orbit.
