Webcast tomorrow: Advanced Technology for Life Detection and Biology . Click here on Thursday at 7 p.m. PST for the webcast. The search for life, along with the precursors and residues of life, is a key theme for science and technology activities at JPL. To prepare for future planetary missions to Mars, Europa and Titan, researchers at JPL are engaged in a broad set of science investigations here on Earth, and numerous advanced technology efforts to develop novel devices to detect life's signatures.
