Mysterious purple coating found on Mars rocks

Red dust paints Mars in ruddy hues, from the surface to the skies. But NASA's Perseverance rover has spotted swaths of another color among the rusty shades. At nearly every site the robotic geologist visits, the Martian palate includes purple. Bradley Garczynski of Purdue EAPS are mentioned is cited in this article by National Geographic.

Major multidisciplinary research partnership with Peruvian university begins third phase

A delegation from the Universidad Nacional de San Agustín (UNSA) in Arequipa, Peru, visited Purdue University’s West Lafayette campus in October to begin the third phase of a major multidisciplinary research partnership. While here, they visited labs across campus including the Stable Isotope Lab and met with EAPS professors Tim Filley, (adjunct), Lisa Welp, and Greg Michalski.

Moons of Mars: New theory for their past and future

As soon as the moons of Mars were discovered by the American astronomer Asaph Hall in 1877, scientific curiosity went into overdrive to answer the age-old question that drives children and scientists alike: Why? Researchers have long asked: Why are they there, and how did they form? We’re exploring those angles plus another aspect: Where are they heading? Dr. David Minton, Purdue EAPS professor, reports about Mars moons on Medium.

An Earth-Like Axial Tilt Might Be Necessary for Complex Life to Arise

Earth has numerous properties that make it an ideal home for life as we know it, including a robust magnetic field that deflects radiation, a temperate climate with liquid water, a large moon that stabilizes the planet’s rotation, and a modest axial tilt. That last item may be more important than we previously thought, according to a new study funded by NASA. The study suggests that a tilted axis leads to more oxygen production, and that means more complex life. Dr. Stephanie Olson of EAPS is cited in this article by 24Tech.
