DailyDirt: Sailing Through Space Without Rockets

from the urls-we-dig-up dept

One of the problems with space travel is that the chemical fuels required to get around in space.. really limit how far a spacecraft can go. A spacecraft can only carry around so much fuel, and then once that fuel is gone, the ship is basically drifting in space. There are some creative solutions to this challenge, though. If you aren't in a hurry, you can try to propel an object with the momentum of light. Or you can shoot very small atoms at high velocity to create thrust. But you cannot change the laws of physics! 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.

    there are no air bubbles floating in water, in any "space walk" videos around the ISS right?

    Nor have their "space suits" accidentally get filled with WATER?

    do some research and you have to admit half of the ISS videos are fake!
