Joe Palca

Joe Palca is a science correspondent for NPR. Since joining NPR in 1992, Palca has covered a range of science topics — everything from biomedical research to astronomy. He is currently focused on the eponymous series, "Joe's Big Idea." Stories in the series explore the minds and motivations of scientists and inventors.

Palca began his journalism career in television in 1982, working as a health producer for the CBS affiliate in Washington, DC. In 1986, he left television for a seven-year stint as a print journalist, first as the Washington news editor for Nature, and then as a senior correspondent forScience Magazine.

In October 2009, Palca took a six-month leave from NPR to become science writer in residence at the Huntington Library and The Huntington Library, Art Collections, and Botanical Gardens.

Palca has won numerous awards, including the National Academies Communications Award, the Science-in-Society Award of the National Association of Science Writers, the American Chemical Society James T. Grady-James H. Stack Award for Interpreting Chemistry for the Public, the American Association for the Advancement of Science Journalism Prize, and the Victor Cohn Prize for Excellence in Medical Writing.

With Flora Lichtman, Palca is the co-author of Annoying: The Science of What Bugs Us (Wiley, 2011).

He comes to journalism from a science background, having received a Ph.D. in psychology from the University of California at Santa Cruz where he worked on human sleep physiology.

So You Landed On Mars. Now What?

The Mars rover Curiosity is beginning its fifth day on the red planet, and it's been performing flawlessly from the moment it landed.

That's been especially gratifying for NASA landing engineer Adam Steltzner. Last Friday, while Steltzner was still on pins and needles waiting for the landing to take place, I told the story of Steltzner's decision as a young man to give up his life as a rocker and go for a career in space engineering.

The newsroom at NASA's Jet Propulsion Laboratory is beginning to thin out as the Mars Science Laboratory transitions from an exciting news story, to a long duration — possibly very long duration — exploration of the geologic and environmental history of Mars.

For the reporters still in the newsroom, fatigue is beginning to set in. BBC science correspondent Jonathan Amos has been at it nonstop for 30 hours. I feel a bit guilty for stepping out and getting a few hours sleep.

If all goes according to plan, the Mars Science Laboratory, nicknamed Curiosity, will land gently on Mars at 10:31 PDT Sunday night. The rover's entry, descent and landing will last for a total of seven minutes. During that time, the rover must slow down from 13,000 mph to a dead-stop touchdown on the surface of Mars.

NASA has sent rovers to explore Mars before. But three words explain what makes this latest mission to Mars so different: location, location, location.

The rover Curiosity is slated to land late Sunday in Gale Crater, near the base of a 3-mile-high mountain with layers like the Grand Canyon. Scientists think those rocks could harbor secrets about the history of water — and life — on the Red Planet.
