NASA’s Curiosity rover has discovered carbon isotopes on Mars which (on Earth) are usually caused by the degradation of biological methane, leading scientists to examine other potential reasons for the molecules.

Last week we talked about balloon-based astronomy. This week we’re gonna talk about putting telescopes on rockets and making observations mid flight. Welcome to the wild world of sounding rockets.
We took a hiatus this summer, but SpaceX sure didn’t, with the tests of the Starhopper prototype. Today we’re going to talk about the revolution in reusable rocketry and quest to build a fully reusable two-stage rocket.
To move around in space, you need some kind of propulsion system. And for now, that means rockets. Let’s learn the underlying science of rockets, and how they work.
Rockets have additional stages to push them into trajectories, like transfer orbits and various orbital maneuvers. Let’s talk about what happens after the rocket is long gone, beyond our sight.
The vast majority of rockets are multi-staged affairs. Why is this? What makes this kind of rocket so successful?
