AAAS Spotlight: Don’t underestimate the value of a spring break field trip. For noble gas geochemist Marissa Tremblay, a geology field trip to Death Valley when she was a freshman at Barnard College set her scientific career in motion. While other students slept in the van on the long drives through the desert, she sat up front asking her professor questions, mesmerized by geological time scales.

Where did Mars's liquid water go? A new theory holds fresh clues.
03-18-2021
By plugging observations of the red planet into new models, a team of geologists and atmospheric scientists, including Purdue EAPS Briony Horgan, has come up with a new picture of Mars’s past: Much of the planet’s ancient water could have been trapped within minerals in the crust, where it remains to this day.
