Satellites are like robots in the sky: they monitor the weather, make GPS possible, and take stunning pictures of outer space! But how exactly do they work? When a satellite named Meep Moop gets delivered to Brains On HQ by mistake, Molly and co-hosts Tessa and Fallyn learn all about satellite solar panels, thrusters, and radio waves! Then, they chat with Dr. Moriba Jah about satellite space junk and the importance of keeping space pristine. Plus, a stumper of a mystery sound! Featured expert:Dr. Moriba Jah, space environmentalist and professor of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin. Find him on Instagram at @moribahjah and Facebook @Moribah Kemessia Jah Special thanks to:Dr. David “Goldy” Goldstein, principal engineer, SpaceX; Colonel., U.S. Air Force, Ret.
