Young scientists and engineers in training are vital contributors to many research projects, including the All-Sky Optical Search for Extraterrestrial Intelligence at Harvard University. That's where 27-year-old doctoral candidate Curtis Mead is research assistant to project head Paul Horowitz. We talk with Curtis about how he got there and what he's learning. Emily Lakdawalla presents a classic Q&A that looks back at Mars Global Surveyor.
