TL;DR

Next-gen microspacecraft using micropropulsion offer cost-effective deep-space exploration and data collection.

Transcript

When you picture a spaceship, you probably think of something like this, or this, or maybe this. What do they all have in common? Among other things, they're huge because they have to carry people, fuel, and all sorts of supplies, scientific instruments, and, in rare cases, planet-killing lasers. But the next real-world generation of spacecraft m... Read More
