We’ve been to the moon and we’ve explored remote corners of our universe. What is next in our quest to unlock the secrets of our solar system?
Hear from Charles Kennel, chair of the National Academy’s Space Science Board and former Scripps Institution of Oceanography director, as he reviews NASA’s past accomplishments, present projects, and anticipated goals in “The Future of Human Space Exploration.”

What were you doing when Curiousity touched down on the surface of Mars?
For those of us in California, the exciting moments of the rover’s descent and landing took place just before bedtime (10:30pm) so we watched it live on the NASA website. Don’t know about you, but we found it hard to hold back the tears as we watched the scientists and engineers at NASA’s Jet Propulsion Laboratory erupt into celebration after the picture perfect landing.
Science is a beautiful thing and we can’t wait to see what Curiosity sends back to Earth in the coming months and years.
In the meantime, let’s look back at Curiosity’s rover predecessors, Spirit and Opportunity, with Steven Squyres, the principle scientist behind the Mars Exploration Rover Project, who visited UC Berkeley in 2011. He shares his experiences working on the mind-boggling project and talks about the future of planetory exploration in these three programs:
Sadly, we learned today that Sally Ride, the first American woman in space, UC San Diego Professor Emeritus, and an advocate for science education, passed away at her home in San Diego. She was 61.
The UC San Diego campus, where Ride became Professor of Physics in 1989 (and where UCTV is based), is already relatively quiet this summer break, but the news of Ride’s premature passing due to pancreatic cancer has created a more somber tone. Her loss will obviously also be felt at the San Diego-based company she founded, Sally Ride Science, which provided science education materials and assistance to teachers and schools.
In February 2011, Ride visited UC Berkeley to deliver the UC Berkeley Physics Regent’s Lecture titled “Reach for the Stars with Sally Ride.” In the talk, she advocates for a stronger foundation of math and science education by describing her own path into the space program. There’s no better way to honor this distinguished woman’s memory than listening to her heartfelt dream that every student — not just future rocket scientists — learn to love math and science.
The end of the world is nigh. At least, that’s what some people think will happen when the Mayan calendar ends on December 21, 2012. But Nobel Prize-winning astrophysicist George Smoot has an entirely different take, one that honors the remarkable precision of the ancient Mayan astronomers and keeps our planet far from imminent disaster.
In “Mayan Cosmology Ends: Precision Cosmology Progresses,” a public talk delivered in front of the Great Pyramid of Kukulcan at Chichen Itza, the Berkeley Lab scientist discusses what the Mayans achieved solely with the naked eye and comments on the significance of the approaching end of the current World Age of the 5,000-year-long Mayan Long-Count Calendar.
No, the end of the world is not at hand, Smoot says, but it’s true that we’re undergoing a fantastic transition in cosmology. The Mayan view of the universe was based on the sun and moon, a handful of planets, and a couple of thousand stars. Ours is an evolving cosmos reaching back over 13 billion years, based on a cornucopia of data accumulating almost daily and including hundreds of billions of galaxies.
In January 2010, UCTV premiered a program from Lawrence Berkeley Lab featuring Saul Perlmutter, along with his colleagues Alexie Leauthaud of the Berkeley Center for Cosmological Physics and David Schlegel of Baryon Oscillation Spectroscope Survey, in a public conversation about the suspected cause of the universe’s accelerated expansion, dark energy, an elusive force that remains science’s biggest unsolved mystery.
