How Can Astronauts Tell How Fast They’re Going?
Physics methods for measuring spacecraft velocity without direct instruments.
“Weirdly, spaceships have no direct way to gauge their own speed. Luckily, we can use some physics tricks to figure it out.”
Why it matters
Weekly Silicon's editorial model scored this 2.90/10 overall, reading it above all as a hardware story — products that turn silicon roadmaps into things you can deploy. Its strongest dimension is technology breakthrough at 6/10 — a genuine capability or engineering advance rather than a routine product update — with economic impact close behind at 2/10, pointing to meaningful consequences for capital, capacity, or competition across the industry. The impact is global rather than tied to one US hub, so the thing to watch is how it filters into domestic supply chains and hiring.
