60,000 miles up: Space elevator could be built by 2035
magine a ribbon roughly one hundred million times as long as it is wide. If it were a meter long, it would be 10 nanometers wide, or just a few times thicker than a DNA double helix. Scaled up to the length of a football field, it would still be less than a micrometer across — smaller than a red blood cell. Would you trust your life to that thread? What about a tether 100,000 kilometers long, one stretching from the surface of the Earth to well past geostationary orbit (GEO, 22,236 miles up), but which was still somehow narrower than your own wingspan?
The idea of climbing such a ribbon with just your body weight sounds precarious enough, but the ribbon predicted by a new report from the International Academy of Astronautics (IAA) will be able to carry up to seven 20-ton payloads at once. It will serve as a tether stretching far beyond geostationary (aka geosynchronous) orbit and held taught by an anchor of roughly two million kilograms. Sending payloads up this backbone could fundamentally change the human relationship with space — every climber sent up the tether could match the space shuttle in capacity, allowing up to a “launch” every couple of days.
The report spends 350 pages laying out a detailed case for this device, called a space elevator. The central argument — that we should build a space elevator as soon as possible — is supported by a detailed accounting of the challenges associated with doing so. The possible pay-off is as simple as could be — a space elevator could bring the cost-per-kilogram of launch to geostationary orbit from $20,000 to as little as $500.
today i heard 2 kids talking about buying fake IDs after school and so i started eavesdropping cuz u know thats big kid stuff and then one was like “yeah but is all this really worth it like im pretty sure the fake IDs cost more than the fish we r gonna buy”
to buy fish at petco u have to be 18 or older
they were going to get fakes to buy fish
i think breasts are great and as a lesbian they are something i find attractive
i don’t see a breastfeeding mother or a woman simply walking around and existing and having breasts as sexual????
idk men are fucking creeps basically
The green algae Volvox, a genus of chlorophytes. The Volvox lifestyle seems to work rather well, as a species they are about 200 million years old. Credit: Casey Dunn
And, as another fun tidbit, volvox may just be a sorta bridge between the gap of unicellular protozoan and early multicellular organisms like sponges. They were of the earliest colonial protozoans ^_^
