NASA’s steampunk solution to space travel
If there’s one thing holding us back from exploring space, it’s fuel. It’s bulky. It’s heavy. And probes must carry their own supply. When that runs out, their lights go out. But what if every asteroid represented a potential pit-stop? The issue of powering craft through space won’t go away. Solar panels can provide all the electricity a space probe needs. But, if it wants to move, it must also have a propellant.
