Dr. Darlene Lim (NASA Ames Research Center)

NASA's Volatiles Investigating Polar Exploration Rover (VIPER) is a planned mission to go to the South Pole of the Moon and get a close-up view of the locations that can sustain water ice – ice that could eventually be harvested to support human exploration on the Moon, on Mars — and beyond. Dr. Lim discusses how, for the first time in NASA’s history, the science team would be fully integrated into the mission operations team and will provide near real-time input on where to explore on the Moon. While the fate of the mission is now in some doubt, Dr. Lim discusses the lessons learned, and the remarkable techniques the team developed to make real-time, almost instant decisions about what the rover does next at each point in its journey. She also tells about how her earlier experience exploring deep lakes on Earth with robotic and crewed vehicles taught her valuable lessons that she could apply to designing lunar exploration protocols.

Dr. Dan Coe (Space Telescope Science Institute)

The Webb Telescope was designed to look back in time, to study the first generation of stars, and reveal our cosmic origins. Now in its second year of operation, JWST has already brought us tantalizingly close to our dream of seeing those first stars. Dr. Coe takes us on a tour of some of the latest results from the telescope, and tells us about his and others' observations of the most distant stars and galaxies astronomers have ever seen, providing a view of the universe as it was 13 billion years ago.

Dan Coe is an Astronomer at the Space Telescope Science Institute (STScI) and Johns Hopkins University in Baltimore. STScI is home to JWST mission control and science operations, where staff scientists like Dan support other astronomers using Hubble and JWST. Dan has also led the Hubble RELICS and JWST Cosmic Spring science teams in discovering and studying some of the most distant galaxies known in the early universe.

Astronomers have now discovered thousands of planets in orbit around other stars. Dr. Weintraub discusses those discoveries, and predicts the progress astronomers are likely to make in their more detailed studies of these planets over the next fifty years. Then he considers the consequences of those potential discoveries for Roman Catholicism, Mainline Protestantism, Christian Creationism, Seventh Day Adventism, Judaism, Islam, and Hinduism -- for all of which the discovery of a planet with life on it may be profound. These thoughts are based on the writings of key religious leaders on this topic -- in the past and in our times.

Dr. David A. Weintraub is Professor of Astronomy Emeritus at Vanderbilt University where he founded and directed the Communication of Science and Technology program, and conducted research on the formation of stars and planets. His most recent book is The Sky is for Everyone: Women Astronomers in Their Own Words (2022; with Virginia Trimble). Previous books include Religions and Extraterrestrial Life: How Will We Deal With It? (2014), Life on Mars: What to Know Before We Go (2018), How Old is the Universe? (2010), and Is Pluto a Planet? (2006). He also created the Who Me? series of inspirational scientific autobiographies for fifth-grade level readers (from World Scientific Publishing), which helps young people see themselves as scientists.
