1 Feb 2012, 22:31 UTC On this episode of Talking Space, we begin our first trip around the table with our insights into Presidential candidate Newt Gingrich’s (R) plan to have a permanent lunar base by the end of his 2nd term. We continue on with the first female cosmonaut to fly since the Soviet Union collapsed. We then move on to a look at the Liberty rocket. Continuing onto our second round, we look at safety risks regarding the ISS and if the current plan for crew evacuation in an emergency is adequate. We then move onto a boat crash carrying sensitive rocket parts. On our final go-around, we discuss more space debris news including everybody’s favorite defunct satellite, Phobos-Grunt. We then continue on with the declassification of military satellites and lastly a look at robotic refueling in space. Talking Space also remembers the crews of Apollo 1, Challenger (STS-51L), and Columbia (STS-107) during NASA’s day of remembrance.

NASA Astrobiology Magazine Podcast

Direct link Material Whirl

31 Jan 2012, 12:00 UTC What's the world made of? Here's a concrete answer: a lot of it is built from a dense, knee-scraping substance that is the most common man-made material. But while concrete may be here to stay, plenty of new materials will come our way in the 21st century. Discover the better, faster, stronger (okay, not faster) materials of the future, and Thomas Edison's ill-conceived plan to turn concrete into furniture. Plus, printing objects in 3D… the development of artificial skin… and unearthing the scientific contributions of African-American women chemists. Guests: Darren Lipomi – Chemical Engineering post-doc, Stanford University's 'Skin Lab' Linda SChadler – Professor of materials science and engineering, and associate dean for academic affairs at Rensselaer Polytechnic Institute, Troy, New York Nicolas Weidinger – Research assistant at the Institute for the Future, Palo Alto, California Jeannette Elizabeth Brown – Retired research chemist; author of African American Women Chemists Robert Courland – Author of Concrete Planet: The Strange and Fascinating Story of the World's Most Common Man-made Material
