Student Rocket Makes It To Space

Where does the Earth’s atmosphere stop and space begin? It is tempting to take the approach Justice Potter Stewart did for pornography when judging a 1964 obscenity case and say “I know it when I see it.” That’s not good enough for scientists, though. The Kármán line is what the …read more

Extraterrestrial Excavation: Digging Holes on Other Worlds

We humans are good at a lot of things, but making holes in the ground has to be among our greatest achievements. We’ve gone from grubbing roots with a stick to feeding billions with immense plows pulled by powerful tractors, and from carving simple roads across the land to drilling …read more

When New Space Loses Out to NASA Pragmatism

In the sixteen years they’ve been in operation, they’ve managed to tick off enough space “firsts” to make even established aerospace players blush. They’re the first privately owned company to not only design and launch their own orbital-class …read more
