Pieces of Mars: How We’ll Get Them to Earth
We now know the rough outline of how NASA and the European Space Agency (ESA) expect to get the samples collected by Perseverance off Mars and into labs on Earth. Mars Sample Return Program Manager Richard Cook of JPL will take us through the intricate and audacious steps required. The plan now includes two Mars helicopters! Trickster Bruce Betts, chief scientist of The Planetary Society, provides the surprising answer for his latest space trivia question. Apollo 11 was not the first liftoff from another world!

A Venus Phosphine Scoop! The Return of Jane Greaves
Astronomer Jane Greaves and her worldwide team have had quite a ride. It has been two years since the Cardiff University professor announced evidence of phosphine in the atmosphere of Venus. Many scientists were and still are skeptical, but Jane is back with more data, including some that she shares with us first. She and Mat talk about what this could mean. Phosphine-belching Venusian penguins are very unlikely, but we want your artists’ concepts of them! That’s in addition to yet another space trivia contest from Bruce Betts.

New Jet Propulsion Lab Director Laurie Leshin
She is only the tenth director of JPL, and the first woman to hold the position. It’s a homecoming for Laurie Leshin who got her PhD at Caltech, the operator of JPL on behalf of NASA. Laurie talks about her priorities for the lab, and how excited she is about the missions already underway and those to come. Planetary Society chief advocate Casey Dreier analyzes Russia’s announcement that it will withdraw from the International Space Station. Casey also shares his love of “Contact.” The classic science fiction film based on Carl Sagan’s novel has just celebrated its 25th anniversary. Bruce Betts will join us for another tour of the night sky and more in What’s Up.

The JWST: An Awesome New Window on the Universe Opens Wide
Have you seen them? Five spectacular images have given us a taste of what’s ahead from the James Webb Space Telescope. Bill Nye will share his reactions after we hear excerpts from NASA’s image revealing event on July 12. We’ll then talk with astrophysicist Tom Greene of the NASA Ames Research Center. Tom has hundreds of hours on the new space telescope to examine planets circling other stars. Planetary Society Chief Scientist Bruce Betts will add his thoughts during What’s Up as he offers a space trivia question that ties the JWST to a long lost fast food hamburger.
