A month before the U.S. election Joe Biden's campaign has yet to state its goals for space and NASA. We asked Jeff Foust, one of the best space reporters in the business, to help us piece together a working model of a potential Biden Administration space policy. We comb through the available evidence, combining insights from Biden's history in the Senate, his 8 years as vice president, and current activities in the Democratic House of Representatives and party platform to create a prediction of what might be the same, and what might differ from the Trump Administration's approach to NASA.

An international team has detected phosphine gas in the clouds above Venus. Naturally-produced phosphine on Earth is created by anaerobic bacteria. We’ll listen to portions of the media briefing at which this result was announced. Then we’ll get perspective on the find from the Planetary Society’s Casey Dreier. Astrophysicist and Venus atmosphere expert Javier Peralta will share his reaction and a big find of his own on our nearest planetary neighbor.

How spacefaring nations prioritize funding can be just as important, if not more so, than the capabilities of the commercial sector, says Dr. Mary Lynne Dittmar, President and CEO of the Coalition for Deep Space Exploration. She joins the show to talk how these complement each other, and why the SLS and Orion programs deserve support along with work by companies like SpaceX and Blue Origin. Mat and Casey also catch up on the dizzying amount of space news in July, including important progress on NASA’s budget from the U.S. House of Representatives.
