This idea helps the astronaut who used to risk their lives in daring spacewalk to fix things on craft’s exterior. (Like they did recently on the international space station to repair cooling system. ) Instead they will command swarms of hull-crawling automatons to do the job.
Stranger still it is in a vacuum. Testing its ability to use dry but sticky gecko, like feet to crawl around an orbiting spacecraft.
what a wonderful technology really it is great idea...
