Our guest today is Dr. Ed Weiler, a retired NASA scientist who spent 20 years as the chief scientist for the Hubble Space Telescope, the forerunner of the James Webb.

During his 33-year NASA career, Ed wore many hats, including Associate Administrator of the Science Mission Directorate; Center Director of NASA’s Goddard Space Flight Center, Associate Administrator for NASA&#39;s Space Science Enterprise, chief of the Ultraviolet/Visible and Gravitational Astrophysics Division and director of the Astronomical Search for Origins Program.

In today’s episode, we talk to Ed about:

-- NASA’s accomplishments in the past year, including the Perseverance mission, the success of the James Webb telescope, and the launch of Artemis-1.

-- Ed’s experience as the Chief Scientist for the Hubble Space Telescope during its early development.

-- Ed’s time as the director of NASA’s Astronomical Search for Origins program.

-- Ed’s role in the development of the New Horizons space craft and its mission to fly by and study Pluto and it’s moons.
