The AAAS has elected three Caltech faculty members—John Brady, Kenneth Farley, and Fiona Harrison—as fellows. Also named to the academy was Katherine T. Faber, who will be joining the Caltech faculty in July.
Several hypotheses have been proposed to explan how clay minerals detected on the surface of Mars were formed. Now, publishing in the journal Nature Geoscience, a team of French and American scientists including Caltech's Bethany Ehlmann, has suggested a new possibility. The Los Angeles Times recently spoke to Ehlmann about the paper and its implications.
On Sunday, August 5, the Mars Science Laboratory (MSL) rover, known as Curiosity, will make its dramatic descent onto Mars's surface. Once it lands, the rover will check its instruments to make sure everything's functioning properly—and then it will get right to work. Caltech's Ken Farley and Bethany Ehlmann will be among the 300 scientists working here on Earth, taking the information Curiosity sends home and trying to figure out what it all means.
Since launching in November 2011, NASA's Mars Science Laboratory (MSL) has been traveling full steam ahead on a journey that will traverse over 350 million miles, ending on the Red Planet at 10:31 p.m. on Sunday, August 5. Tucked into a spacecraft for safekeeping during flight, MSL contains a rover named Curiosity. Here are some facts about Curiosity and the mission.
With the Mars Science Laboratory (MSL) well on its way to Mars, the newest members of its science team have been announced. Two Caltech professors—Kenneth Farley and Bethany Ehlmann—are among 18 researchers who have been selected as funded participating scientists on the mission.
Ever since a crash landing on Earth grounded NASA's Genesis mission in 2004, scientists have been gathering, cleaning, and analyzing solar wind particles collected by the spacecraft. Now, two new studies published in Science reveal that Earth's chemistry is less like the sun's than previously thought.
That dry, dusty moon overhead? Seems it isn't quite as dry as it's long been thought to be. Although you won't find oceans, lakes, or even a shallow puddle on its surface, a team of geologists has found structurally bound hydroxyl groups (i.e., water) in a mineral in a lunar rock returned to Earth by the Apollo program.
Researchers at the California Institute of Technology (Caltech) and their colleagues have found evidence of ancient climate change on Mars caused by regular variation in the planet's tilt, or obliquity. On Earth, similar "astronomical forcing" of climate drives ice-age cycles.
