A Fond Farewell to Spirit and Opportunity Feb 20, 2019

Show notes

The Mars Exploration Rover mission was declared complete on February 13, 2019. On the very next day, MER Project Manager John Callas and Deputy Project Scientist Abigail Fraeman came to Planetary Society headquarters for an extended and emotional conversation with Mat Kaplan and Emily Lakdawalla. They talked about the beloved rovers and the women and men of the team that has guided them for so many years. What’s Up offers another opportunity to win a coveted rubber asteroid as we learn about the night sky and more.

Watching the Births of Solar Systems Feb 13, 2019

Show notes

Radio telescopes are delivering stunning images that, in some cases, current optical telescopes can’t equal. Witness the 20 beautiful protoplanetary disks imaged by the DSHARP team using the ALMA radio telescope in Chile. The diversity of these proto-solar systems is astounding. Principal investigator Sean Andrews will tell us how the pictures were created, and why they are surprising and delighting astronomers. Senior editor Emily Lakdawalla is literally looking back on objects around our own solar system. She tells us how backlit images reveal their secrets. The rubber asteroids have returned! You can win one in this week’s space trivia contest.

The DART Mission: Learning How to Swat Dangerous Asteroids Feb 06, 2019

Show notes

Why did the dinosaurs die? Because they didn’t have a space program! The upcoming DART mission will test our best thinking about how we may someday deflect a Near Earth Object that is speeding toward fiery Armageddon on Earth. Nancy Chabot of the JHU Applied Physics Lab is the mission’s Coordination Lead. The Curiosity rover has reached an exciting new region of Mars. Senior Editor Emily Lakdawalla will give us the lowdown. The night sky is full of treasures according to Bruce Betts. Join Bruce and Mat for this week’s What’s Up.

Space Policy Edition: Should the U.S. be in a space race with China? Feb 01, 2019

Show notes

China's space program notched an impressive "first" last month when its Chang'e 4 spacecraft landed on the far side of the Moon. The U.S. space program, in contrast, was in the midst of an extended shutdown. Some observers expect China's growing space capability and lunar ambitions to trigger a new space race. Not Dr. Roger Handberg, Professor of Political Science at the University of Central Florida. He discusses how the current geopolitical situation differs from the Cold War standoff between two superpowers, and how we shouldn't expect dollars to flow back to the U.S. space program as a consequence of China's space successes. Cooperation, or even friendly competition, is a much more likely outcome than a new space race.

Where Do We Come From? The Origin of Life Jan 30, 2019

Show notes

Astrobiology is the discipline that explores the origin of life in the universe, and whether life exists anywhere other than Earth. It’s an increasingly exciting field according to University of Washington Research Associate Michael Wong. Mike reviews the current thinking and provides some of the chemical basis for life as we know it, and possibly as we don’t know it. Planetary Society Senior Editor Emily Lakdawalla explains why we don’t see stars in many images of bodies across the solar system, while Society CEO Bill Nye marks the end of the US government shutdown that has hampered so much science. Five more winners will receive copies of First Man in this week’s What’s Up space trivia contest.

Show notes

Spacecraft OSIRIS REx is now orbiting a 260-meter asteroid named Bennu. Principal investigator Dante Lauretta returns to tell us what has already been learned, and to preview the excitement that is still to come, including the probe’s descent to the surface for collection of a pristine sample. Want one of five Blu-ray copies of First Man, the movie about Neil Armstrong? Consider entering this week’s What’s Up space trivia contest that also offers Dante Lauretta’s two great board games about space exploration and astronomy.

Space Policy Edition: Shutdown Jan 18, 2019

Show notes

In a government shutdown seemingly without end, we bring you two stories from individuals directly impacted by the crisis. NASA scientist and union representative Lee Stone discusses the missed paychecks, loss of science, and lasting negative consequences to the public sector scientific workforce. Rob Hoyt, CEO of Tethers Unlimited, a small business in Washington state that was forced to lay off 20% of its workforce due to unpaid NASA contracts, describes the impact on contractors that may never see repayment or reimbursements. The Planetary Society has a petition to end the shutdown.
