Casey Dreier

Chief of Space Policy for The Planetary Society

On December 11th President Donald Trump signed a memorandum that firmly points the US space effort toward the Moon, but without providing many details. Planetary Society Director of Space Policy Casey Dreier fills in some of the gaps left by this executive directive. Poor Venus! Digital Editor Jason Davis explains why the cloud-shrouded furnace planet has been ignored by NASA for many years. Cowabunga! Bruce Betts and Mat Kaplan head for the warm beaches of Southern California for an on location edition of What’s Up.
