New state-of-the-art chronologic measurements of rocks brought to Earth by Apollo astronauts reveal that many of the historical age determinations are erroneous. The new measurements presented by cosmochemist Lars Borg demonstrate that the Moons mantle and crust formed contemporaneously between 4.33 and 4.38 billion years ago.

Return to Apollo: Geologic Evolution of a Young Moon

Limited medical equipment on space craft makes medical care in space a real challenge. Ordinary problems must be dealt with, as well as problems related to the unique environment of space. As NASA plans for new crewed exploration missions, beyond low earth orbit, telemedicine support will be limited, and medical evacuation to earth will no longer be possible. To address this problem, LLNL and NASA Ames Research Center are developing a novel diagnostic instrument to help provide medical care on deep space missions. The technology consists of a blood analysis system, based on microfluidics, together with a breath analysis system that uses carbon nanotube sensors. The technology is designed to support future missions to the moon and Mars, and it is expected to be used for terrestrial medicine as well, in a variety of arenas where medical resources are limited.

Health in Space: Developing New Tools for the Trip to Mars

Our planet has been continually bombarded by asteroids since its formation, 4.5 billion years ago. While the frequency of large impacts has decreased, many potential Near-Earth Object threats remain undiscovered, so if or when they will impact Earth remains unknown. Fortunately, if an Earth-threatening asteroid is discovered in time, there are ways to mitigate or even prevent a disaster. Scientists at LLNL provide computer simulations in preparation these scenarios so if the time comes where an asteroid is headed our way, we will be prepared.

Scott Kelly spent a year in the International Space Station while his identical twin Mark Kelly was on earth. UC San Diego and many institutions studied the mental, cardiovascular, immune, genetic, muscular, microbial, bone, and eye changes in both twins to see the effects of long-term space travel. Changes were troubling, so NASA plans several more long-term space flights that will focus on genetic changes, bone loss, loss of vision, brain swelling, and Nutrition. Michael G. Ziegler, MD, is Professor of Medicine Emeritus at UCSD. He has studied astronaut health since 1978. He chaired NASA’s yearly cardiovascular reviews, helped devise current astronaut protocols, and studied physiologic and genomic changes during the Year in Space study.   Series: "Osher UC San Diego Distinguished Lecture Series" [Health and Medicine] [Science] [Show ID: 35085]

Cosmologist and author of "Losing the Nobel Prize" Brian Keating tells the inside story of BICEP2’s mesmerizing discovery and the scientific drama that ensued in this interview with science fiction author David Brin. Keating describes a journey of revelation and discovery, bringing to life the highly competitive, take-no-prisoners, publish-or-perish world of modern science. Along the way, he provocatively argues that the Nobel Prize, instead of advancing scientific progress, may actually hamper it, encouraging speed and greed while punishing collaboration and bold innovation. In a thoughtful reappraisal of the wishes of Alfred Nobel, Keating offers practical solutions for reforming the prize, providing a vision of a scientific future in which cosmologists may, finally, be able to see all the way back to the very beginning.

Losing the Nobel Prize with Brian Keating

The first detection of gravitational waves from the cataclysmic merger of two neutron stars, and the observation of visible light in the aftermath of that merger, finally answer a long-standing question in astrophysics: Where do the heaviest elements, ranging from silver and other precious metals to uranium, come from?

What effect does space travel have on our bodies and minds? As NASA looks to explore Mars and beyond, it is critical to understand the impacts of spending extended time in space. Brinda K. Rana, Phd, shares the results of NASA's Twins Study that focused on astronaut Scott Kelly who spent nearly one year living on the International Space Station and his identical twin brother, Mark, who remained on Earth.

In this candid and heartwarming interview, Tam O'Shaughnessy, the life partner of the late astronaut Sally Ride, describes her long relationship with the first American woman in space. From their days on the teen tennis circuit in California through Sally’s historic flights on the Space Shuttle Challenger to their parallel academic careers and later, founding their own company, Tam tells how their deep friendship blossomed over time into a romance that ended with Sally’s death from cancer in 2012. As the Executive Director of Sally Ride Science@UC San Diego, Tam continues to inspire girls to embrace STEM, and shares her profound pride as the sponsor of the newly commissioned R/V Sally Ride, the first Naval academic research vessel ever named for a woman, now operated by the Scripps Institution of Oceanography at UC San Diego.

Karin Sandstrom studies the interstellar medium - the dust and gas in galaxies and between stars, and especially how ultraviolet light interacts with soot-like polycyclic aromatic hydrocarbons. That, she says, is key to everything - how stars (and planets) form, how galaxies evolve, and perhaps how life emerged. Series: "Women in Science" [Science] [Show ID: 30014]
