Walkabout the Galaxy

The astroquarks welcome noted science blogger and author Dr. Ethan Siegel whose new book Treknology takes a look at the intersection of science and science fiction. While you may already have a tablet computer, warp drive is probably still a few years away. But Elon Musk may be sending missions to the moon in less time than it takes the U.S.S. Enterprise to complete its 5-year mission (so, less than 5 years, get it?). Tune in for the latest news on exploration of the solar system as well as a look back to some classic Trek-nology with Dr. Ethan Siegel on this episode of Walkabout the Galaxy.

The astroquarks welcome WMFE space reporter Brendan Byrne who recounts his flight on the SOFIA airborne observatory. They hen vent about how the Nobel Prize committee has unaccountably once again passed them over. Here about this year's winners in physics, and a discussion of the history of the Kuiper Belt in this episode's space trivia.

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.
