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.

Observing with the James Webb Space Telescope: Glimpsing the First Stars

Nov. 13, 2024
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.

Copernicus 4.0: How the Views of Earth's Importance and the Search for Life are Changing

Mar. 5, 2025

Dr. Simon Steel (SETI Institute)

Dr. Steel discusses the Copernican revolution and how it changed humanity's view of its place in the universe. He then talked about other "Copernican" discoveries that displaced us from a central perch, including the revision of our place in the Galaxy, the discovery of other galaxies, and now our finding a remarkable number of planets (including Earth-like planets) orbiting other stars. He explains how such discoveries give context for, and have prepared us for, the next potential Copernican revolution, the discover of intelligent life elsewhere in the cosmos. He concludes by describing some of the most exciting experiments now underway to find evidence of such life among the nearest stars and busiest galaxies. Dr. Steel is Deputy Director of the Carl Sagan Center for Research at the SETI Institute.
