Viewing Mercury with X-Ray Vision; June 15th, 2012
While Superman can see through walls using X-ray vision, instruments aboard the MESSENGER spacecraft can use X-rays to do a lot more: they can determine the presence and abundance of a host of important elements in the planet’s surface. AAAS Science Update host Bob Hirshon spoke with geologist and MESSENGER post doctoral fellow Shoshana Weider about what the X-ray view is revealing about the planet.
Take Mercury for a Spin; May 11th, 2012
The Google Earth platform is useful for more than just checking out Earth-bound topography and features. AAAS Science Update host Bob Hirshon spoke with ace programmer Jason Smith, of Silicon Valet, about how he converts raw image data of the planet Mercury taken by the MESSENGER spacecraft into KML files that map the imagery onto the Google Earth sphere. The result? A detailed Mercury globe that anyone can take for a spin.
As the Sun Burps; March 9th, 2012 When the Sun emits what is euphemistically called a “coronal mass ejection,” belching billions of tons of ionized plasma into space, satellites can fail and power grids can shut down on Earth, 150 km away. So imagine the effects on Mercury, just a third of the distance from the Sun, and defended by a much weaker magnetic field. In this podcast, Science Update host Bob Hirshon speaks with MESSENGER scientist Daniel Baker, Director of the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder, about how violent space weather is both an opportunity and a challenge for MESSENGER’s mission to Mercury.
