Q&A with Jonathan Lunine on Enceladus’ prospects for life

Jamie Bock, a professor of physics at Caltech, is principal investigator of the SPHEREx astrophysics mission selected by NASA on Feb. 13 as the next medium-class mission in the agency’s line of Explorer probes.

Scientists examining data from the Cassini mission’s final months reported this week unexpected measurements of Saturn’s gravity field and outer atmosphere, suggesting they may have to revisit theories about the planet’s rings and the forces that generate magnetic fields.

Andrew Driesman is project manager for NASA’s Parker Solar Probe mission at the Johns Hopkins University Applied Physics Laboratory, leading a team of engineers and operators in charge of the first mission to fly through the sun’s atmosphere.
