Walkabout the Galaxy
gravitation assist, OSIRIS-Rex, black hole collisions
Astrophysics and Astronomy | Physics
How exactly (and why) does a spacecraft get a "gravitational assist" from a planet en route to another planet? Where does that energy come from? The Astroquarks take a look at gravity assists and the OSIRIS-REx mission to grab some bits of a Near-Earth Asteroid and bring them back to Earth. Plus, the field of gravitational wave astronomy expanded now with the detection of a new black hole collision by two separate gravitational wave observatories. It's a weighty episode.
Well, baby brother, congratulations on your new show, "The Orville". I understand that my own show, based on a giant space-faring bicycle called "The Wilbur", is in the works. I'm also pretty sure that The Wilbur is a bigger and faster ship than The Orville and with a significantly less-silly crew. My captain will not be discussing his nighttime urination habits with his crew, and The Wilbur is powered by a 24-speed Shimano dilithium high gear-ratio warp drive derailleur with disk brakes and a lightweight carbon fiber frame for rapid climbs out of planetary and stellar gravitational wells. The Wilbur, coming soon, is proud to bring you this episode of Walkabout the Galaxy. With the Wilbur you won't need to walk anymore!
