The Black Point Lava Flow in northern Arizona offers a research haven for NASA's Desert Research and Technology Studies (RATS) team of scientists and engineers, because this rough, dusty terrain, with its extreme temperatures that swing from hot to cold, resembles other places in the solar system. On this bleak landscape, NASA crews can test robotic systems and extravehicular equipment; adjust and improve their designs; and create effective procedures for solar-system exploration. NASA scientist Jacob Bleacher visited the Library of Congress to discuss "NASA's Desert RATS".
Speaker Biography: Jacob Bleacher is a research geophysicist in NASA's Science and Exploration Directorate at Goddard Space Flight Center.

During World War II, Chicago led the nation in urban food production with its Victory Gardens program of 1,500 community gardens and more than 250,000 home gardens. The city's North Park neighborhood was also home to the largest Victory Garden in the United States. In fact, the Victory Gardens campaign in Chicago was so successful that it was emulated across the country. Seventy years later, Chicago continues this tradition with an estimated 700 community gardens. In 2010, LaManda Joy launched the Peterson Garden Project, on land that was part of an original World War II Victory Garden from 1942-1945. The Peterson Garden is Chicago's largest community-allotment vegetable garden, with 157 plots tended by community members growing only organic vegetables. Volunteers and students also tend several garden plots and donate their produce to local food pantries and homeless shelters.
Speaker Biography: LaManda Joy is an award-winning gardener, blogger and founder of Chicago's Peterson Garden Project.

The Antarctic and Greenland ice sheets contain 99 percent of the Earth's fresh-water ice, according to NASA scientist Lora Koenig. Changes to these regions can profoundly affect sea level and the rate at which the Earth's climate warms or cools, placing them at the heart of research into the planet's future. To understand the current state of the ice sheets and to model the future, scientists spend months at a time on the ice in challenging darkness, frigid temperatures and high winds. Koenig, who is one of these scientists, will discuss how they must learn to solve practical problems of survival and travel through extreme environments while they take precise measurements with specially-designed instruments.
Speaker Biography: Dr. Lora Koenig is a physical scientist in the Cryospheric Sciences Laboratory at NASA's Goddard Space Flight Center. She is an expert in remote sensing of ice sheets and snow. Dr. Koenig is interested in detecting accumulation rate changes over ice sheets using passive microwave satellite sensors, which stand out for their long temporal record of over three decades. She studies the Greenland and Antarctica ice sheets on very small scales, using field techniques like snow pits and ice cores, and over broad scales, using airborne and space-borne sensors. Her ground-based studies have included spending over 12 months in the Arctic and Antarctic to validate satellite measurements and expand algorithms over large areas where ground data are lacking due to harsh conditions.

In 1968, Apollo 8 astronaut William Anders took an image of planet Earth as it emerged from the lunar horizon. The picture, "Earthrise," changed forever society's view of our celestial home, according to NASA Chief Scientist Waleed Abdalati. The image of Earth--beautiful and vulnerable, and suspended in dark stillness--inspired an appreciation that there is one human race, whose fate hinges delicately on mankind's collective actions. Abdalati demonstrates the tremendous power of the space-based perspective in science, exploration and in daily life.
Speaker Biography: Waleed Abdalati was appointed NASA chief scientist on Jan. 3, 2011, serving as the principal adviser to NASA Administrator Charles Bolden on NASA science programs, strategic planning and the evaluation of related investments. He left NASA at the end of 2012.
