Callahan M.
Video Interview
Take a step by step tour of how NASA researchers hunted for nucleobases, the building blocks of DNA, in meteorites. This technique helped them conclude that nucleobases might have been made on meteorites in space and then delivered to a primitive Earth. Seen in the video is Michael P. Callahan, a research physical scientist in the Astrobiology Analytical Laboratory at NASA Goddard Space Flight Center.
