Episode 202: Model Styrofoam Planets on the Ceiling or in Space?
12 Jan 2010, 03:26 UTC
In this first round-table discussion of 2010, we discuss a large amount of topics going around in the short time that the new year has been with us. We discuss Charlie Bolden’s speech at the AAS, and that’s not meant as a dirty word, that is the American Astronomical Society. We also talk about the launch of STS-130 which probably won’t be February 7th anymore. We then lead in to the possibility of the shuttle not finishing its flights by December 2010 and Spirit’s Martian woes as it celebrates its 7th birthday stuck on a rock. We then discuss Kepler’s findings of 5 exoplanets in its 6 weeks of operation and a patch contest to commemorate the shuttle program.

Host this week: Sawyer Rosenstein. Panel Members: Gina Herlihy , Gene Mikulka , Mark Ratterman and special guest Scott Parazynski . Announcer: Russ Dale (@flight001), Theme Composed by:Todd Cecilio (@negativereturn). Also a very special thanks to Jen Scheer (@flyingjenny) for designing the amazing Talking Space logo. Of course, a special thanks to you, the listener, for making this podcast a success and bringing us to our second season! Remember to email us with questions or comments as text OR an .mp3.

Dear Talking Spacers,
With regards to measuring density of exoplanets, if the the doppler radial shift of an exoplanet acting on its host primary can be measured, the hidden objects minimum mass can be known. In the case of a transiting exoplanet, a rough idea of its volume can be gauged due to the light drop observed, and the mass known with greater precession, since it transits along our line of sight. Once mass and volume is known, a rough estimation of average density can be given. Excellent podcast, and one of the very few I subscribe to!
Thanks,
Dave Dickinson
