When the United States Postal Service chose UC San Diego as the site to unveil its new Sally Ride Forever postage stamp, the UCSD community could not have been more thrilled. Ride, the first American woman in space, taught physics at UCSD after finishing her stellar run at NASA and then, through Sally Ride Science, inspired a new generation to embrace STEM. As seen in the Stamp Dedication Ceremony [uctv.tv/shows/33665] and the Women in Leadership [uctv.tv/shows/33160] discussion that followed, Dr. Ride’s fellow trailblazers Billie Jean King, Ellen Ochoa, Lynn Sherr and Condoleezza Rice, proudly honored the memory of their late friend.
The 12th NASA Administrator, Charles F. Bolden Jr., shares how NASA’s programs and missions function as an instrument of international cooperation, demonstrating the steady guidance of the United States as the world’s leader.
Researchers love identical twins. Because they have the same genetic code, they provide a unique opportunity to determine how environment may lead to developmental differences – i.e. nature vs. nurture.
In this new program from the Stein Institute for Research on Aging, Brinda K. Rana, PhD, shares the results of NASA’s remarkable Twins Study. In March 2015, U.S. astronaut Scott Kelly embarked on a one year mission onboard the international space station. Meanwhile, his identical twin brother, Mark, remained on Earth giving scientists an opportunity to study the long-term effects of space travel on the human body versus normal development.
Ultimately, NASA wants to know what will happen to astronauts as they inch closer to their Mission to Mars. Space is a harsh environment, both physiologically and psychologically. Astronauts must contend with microgravity, disruptions in sleep cycles, radiation, and dietary limitations, as well as confined spaces and isolation from friends and family. What will happen to astronauts after 3 years – the time it will take to get them to Mars and back again?
But these studies not only have implications for the lives of astronauts. Physiologically, space travel mimics the effects of aging on the human body, changes such as cardiovascular decline, vision problems, muscle and bone atrophy, and cognitive impairment. Any discovery that improves the lives of astronauts in space could also be used to help us right here on Earth.
Learn more about what it took to plan and execute the Twins Study, as well as some of what they’re just beginning to discover. Watch Twins in Space: The Effects of Space Travel on Humans.

After traveling through the inner solar system for seven years, NASA’s MESSENGER spacecraft reached Mercury in March 2011 and became the first ever mission to orbit this mysterious planet. Since then, MESSENGER has been making measurements with its suite of scientific instruments, including gamma-ray, neutron and x-ray spectrometers, magnetometer, laser altimeter, cameras and other instruments.
In the latest program from Lawrence Livermore National Laboratory, physicist Morgan Burks explores the mysteries surrounding Mercury’s formation and composition, and the instruments that need to work at cryogenic temperatures in one of the hottest places in the solar system.
