NASA hopes to eventually build a base on the moon to launch missions to other planets, including Earth. University of Florida researchers have designed a process that converts human waste into methane to be used as fuel that can propel spacecraft from the moon back to Earth. Pratap Pullammanappallil, a UF associate professor in agricultural and biological engineering, seen here standing in his Gainesville lab, worked with a former graduate student on the research.
