How I Landed on Mars

Caltech geology graduate student Katie Stack says her Caltech experience has provided her with the best of both worlds. Literally. As one of five Caltech graduate students currently staffing the Mars Science Laboratory mission, Stack is simultaneously exploring the geologic pasts of both Mars and Earth. She and her student colleagues apply their knowledge of Earth's history and environment—gleaned from Caltech classes and field sites across the globe—to the analysis of Curiosity's discoveries as well as the hunt for evidence of past life on the Red Planet.

Cassini Turns 15

Fifteen years after its launch, the Cassini mission to Saturn continues to give us a close-up, long-term view of the ringed planet and its astonishingly diverse collection of moons. Here are some of the highlights so far.

Planetary Weatherman: An Interview with Andrew Ingersoll

Andrew Ingersoll, Earle C. Anthony Professor of Planetary Sciences, has been a leader in the investigation of planetary weather and climate for nearly five decades. His research has included studies of the so-called runaway greenhouse effect that is thought to have boiled away Venus's oceans, the presence of liquid water on Mars, the supersonic winds on Jupiter's moon Io, and the atmospheric dynamics of Jupiter, Saturn, Uranus, and Neptune.

Caltech Again Named World's Top University in <i>Times Higher Education</i> Global Ranking

PASADENA, Calif.—The California Institute of Technology (Caltech) has been rated the world's number one university in the 2012–2013 Times Higher Education global ranking of the top 200 universities.

Oxford University, Stanford University, Harvard University, and MIT round out the top five.

Mars Rover Finds Evidence of Ancient Streambed

An ankle- or hip-deep stream once flowed with force across the surface of Mars in the very spot where NASA's Curiosity rover is currently exploring. The finding, announced by members of the project's science team today at the Jet Propulsion Laboratory (JPL), provides new information about a once wet environment in Gale Crater, the ancient impact crater where the rover touched down in early August.

Two Caltech Researchers Receive NIH Director's Awards

Two members of the California Institute of Technology (Caltech) faculty have been given National Institutes of Health (NIH) Director's Awards. The awards are administered through the NIH's Common Fund, which provides support for research deemed to be both innovative and risky.

Martian Clay Minerals Might Have Much Hotter Origin

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.

Geologists in the Field

Field geologists at Caltech come face to face with bears and wolverines, climb steep cliffs and mountains, and endure scorching sunlight and frigid temperatures. Sometimes risking life and limb, they travel to some of the most remote corners of the globe—all in the name of science

Anchors Aweigh

At Caltech, hydrophilic researchers in the Division of Geological and Planetary Sciences take to the salty seas to gather data, explore the deep, and get a firsthand view of the beasts at the bottom. The briny treasures they collect along the way are helping them learn more about past, present, and future environmental conditions and hazards.
