I found this article on space.com, about a new kind of technology called SpiderFab, which is a spiderlike robot supposed to be able to build new structures in space one piece at a time, the same way spiders spin their webs. This robot could help build big radio antennas, spacecraft booms and solar arrays in the next decade or so.
Rob Hoyt, CEO of Tethers Unlimite, the company that is currently developing this new technology, says that their long-term objective for all of this work is to eventually enable the use of in-situ resources to construct the infrastructure in space needed to support humanity's expansion throughout the solar system. The payoff could be higher sensitivity and bandwidth for for example NASA missions.
At the heart of the SpiderFab concept is a multiarmed robot that would fabricate structural elements with one "spinneret" and use another one to join these pieces together as it crawls about on the ever-growing "web."
For example, in a project funded by NASA's Small Business Innovation Research program, the company already built a machine that creates lightweight structural trusses from raw carbon-fiber spools, using a process akin to 3D printing.
This machine, which is about the size of a microwave oven, can churn out the type of objects that could be put together to form a spacecraft boom and other systems at the rate of 5 centimeters per minute.
"In a perfect world — if funding flowed and the contracting process didn't drag on forever — we think we could get to be able to build very large support structures for antennas and solar arrays, and those sorts of components, in the early 2020s,"
- Rob Hoyt
Space is a topic people have been obsessed about for decades, and this might be just a tiny step towards knowing what's actually out there, but it could be a huge leap for our future lives on Earth. Imagine, if they could build better antennas and such in space, how that could improve for example our internet- internet connectivity in the near future. And that's not all that would change.
