Learning to Fly (with Ingenuity)

Sabrina Pirzada

When the Ingenuity helicopter lifted off the dusty surface of Mars on April 19, 2021, it marked an extraordinary accomplishment: the first powered flight on another planet. Here on Earth, graduate student Alejandro Stefan-Zavala watched in amazement, knowing he had helped give Ingenuity its first breath of wind.

At Caltech's Center for Autonomous Systems and Technologies (CAST), graduate student Alejandro Stefan-Zavala runs experiments to understand autonomous drone flight.

Gravitational-wave observatories release new catalog of detections

The newest findings from LIGO, Virgo, and KAGRA more than double the catalog and include a variety of heavy, fast-spinning, and lopsided colliding black holes.

Two black circles appear to merge like bubbles with stars in the background.

The Rocks Remember: What the Rovers Have Taught Us About Habitability on Mars

Sabrina Pirzada

In 2012, NASA's Jet Propulsion Laboratory, managed by Caltech, delivered a car-sized rover outfitted with a full geochemistry laboratory to the surface of Mars to investigate a question that has persisted across generations: whether the planet has ever sustained the conditions necessary for life.
