Podcast Episode 97: Mars InSight

NASA Mars InSight Lander Principal Investigator Bruce Banerdt discusses the first mission dedicated to studying the deep interior of Mars.

A meteoroid slammed into the surface of Mars on December 24, 2021, leaving this massive crater and ejecting boulders of water ice across a wide area. In the months that followed, two NASA teams pieced together what the impact was and what it reveals about the planet’s crust. Credit: NASA/JPL-Caltech/University of Arizona

Podcast Episode 96: Airworthiness

NASA Armstrong Flight Research Center Chief Engineer CJ Bixby discusses what it takes to achieve airworthiness.

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance. This image is a blend of 171 and 193 angstrom light as captured by the Solar Dynamics Observatory. Credit: NASA/GSFC/SDO
