Yep, here are some of the cool things from the news today.

Yesterday I talked about some of the exciting space missions on the docket for 2021.

Among them, at least two rovers from the U.S. and China will touch down on Mars next month.

And while they're there, if they experience any kinds of breakdowns, there's not too much that can be done.

Now, these are super sophisticated planetary exploration robots, so major breakdowns aren't exactly

expected, but the rovers aren't designed to self-repair. And even if they were, they don't

come stocked with backup equipment like the spare tire on the back of a Jeep. That's why scientists from the Grasp Lab at the University of Pennsylvania have proposed a new

way for exploration robots to make their own structural components out of a material that's readily

available in many places these robots are sent to. Ice. Now, of course, being ice, we're not talking

about any electrical or super complicated components, but more structural things, like a wheel

that could be made in a pinch. The scientists who presented their work recently at the IEEE

RSJ International Conference on Intelligent Robots and Systems, or IROS, stress that they are in the
