NSF announces two awards through the Centers for Innovation and Community Engagement in Solid Earth Geohazards
NSF — The U.S. National Science Foundation has announced two awards through the Centers for Innovation and Community Engagement in Solid Earth Geohazards program. The Cascadia Region Earthquake Science Center (CRESCENT) and the Statewide California Earthquake Center (SCEC) will receive almost $21 million over the next five years to advance research on Earth processes that underpin natural hazards like earthquakes and tsunamis. Dr. Jonathan Delph, of Purdue EAPS, is one of the senior personnel for the "Cascadia Velocity Model" group in the CRESCENT project.

Optimizing Carbonate Classification on Mars
EOS — Combining data from several of Perseverance rover’s spectroscopic sensors offers a more accurate means to classify carbonate minerals that may hold hints of ancient life. This EOS article is sourced from a recent AGU publication in which Dr. Roger Wiens of Purdue EAPS is an author.

Purdue research: Ice caps on Mars may reveal planet’s climate history
PURDUE NEWS — A team of scientists, led by Purdue University’s Department of Earth, Atmospheric, and Planetary Sciences professors Ali Bramson and Michael Sori, set out to unlock the hidden, historic secrets within ice caps on Mars and published their findings in the Journal of Geophysical Research: Planets.

NASA Astronaut Andrew Jay (Drew) Feustel to Leave NASA
NASA — NASA astronaut and geophysicist Drew Feustel, a veteran of three space missions and nine spacewalks, who also held key leadership positions within the Astronaut Office at NASA’s Johnson Space Center in Houston, is retiring from the agency after 23 years. Feustel spent 226 days in space over three missions, servicing the Hubble Space Telescope from space shuttle Atlantis and flying to the International Space Station twice on two different spacecraft – the space shuttle Endeavour and a Soyuz spacecraft.

Measuring Decays with Rock Dating Implications
APS — The measured decay rate of potassium-40 implies a smaller probability of this decay mode than previously assumed. The results will have limited but important implications for the field of geochronology, as well as for other fields that either use or seek to avoid the effects of the decay of this ubiquitous element. Dr. Ryan Ickert, of Purdue EAPS, aided in the rock clock recalibration as discussed in American Physical Society (APS)'s Physics Magazine.
