Whenever someone needs a hand in advanced robotics, they ask for Yuri Carrillo. She can do just about anything, from finding and replacing bad wires to integrating new circuit boards on scientific instruments. But Carrillo is not a regular JPL employee. An 18-year-old sophomore studying electrical engineering at Cal Poly San Luis Obispo, Carrillo is one of more than 300 students who have swelled the Lab's ranks this summer, hailing from high schools, community colleges, four-year universities...

Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif.,  have obtained the first images of asteroid 2007 TU24 using high-resolution radar data. The data indicate the asteroid is somewhat asymmetrical in shape, with a diameter roughly 250 meters (800 feet) in size. Asteroid 2007 TU24 will pass within 1.4 lunar distances, or 538,000 kilometers (334,000 miles), of Earth on Jan. 29 at 12:33 a.m. Pacific time (3:33 a.m. Eastern time). "With these first radar observations...

PASADENA, Calif.- The potential of carbon nanotubes to diagnose and treat brain tumors is being explored through a partnership between NASA's Jet Propulsion Laboratory, Pasadena, Calif., and City of Hope, a leading cancer research and treatment center in Duarte, Calif. Nanotechnology may help revolutionize medicine in the future with its promise to play a role in selective cancer therapy. City of Hope researchers hope to boost the brain's own immune response against tumors by delivering...

The radar system on the European Space Agency's Mars Express orbiter has uncovered new details about some of the most mysterious deposits on Mars: the Medusae Fossae Formation. It has provided the first direct measurement of the depth and electrical properties of these materials, providing new clues about their origin. The Medusae Fossae Formation consists of enigmatic deposits. Found near the Martian equator along a divide between highlands and lowlands, they may represent some of the...

Vast, yet remote; frigid, yet teeming with life; stark and barren, yet serenely beautiful -- these are just a few of the contradictions of Earth's polar regions. Within their frozen confines lie secrets -- clues scientists believe can help unravel some of the mysteries that drive Earth's climate. That's because Earth's poles are sensitive barometers to climate change. They react quickly to a warmer environment, and the effects of these reactions are felt on a global scale. In the past 125...

JPL -- The first test images of Mars from NASA's newest spacecraft provide a tantalizing preview of what the orbiter will reveal when its main science mission begins next fall. Three cameras on NASA's Mars Reconnaissance Orbiter were pointed at Mars at 8:36 p.m. PST Thursday, while the spacecraft collected 40 minutes of engineering test data. The cameras are the High Resolution Imaging Science Experiment, the Context Camera and the Mars Color Imager. "These high-resolution images of Mars...

JPL -- NASA's long-lived Mars rovers demand lots of care as they age and the Martian winter approaches. Dr. John Callas, newly named project manager for NASA's Mars Exploration Rover mission, is coordinating the work to meet these challenges. He is a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. He was named project manager after earlier roles as science manager and deputy project manager for the Spirit and Opportunity rovers. "It continues to be an exciting adventure...

JPL -- NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus. The rare occurrence of liquid water so near the surface raises many new questions about the mysterious moon. "We realize that this is a radical conclusion -- that we may have evidence for liquid water within a body so small and so cold," said Dr. Carolyn Porco, Cassini imaging team leader at Space Science Institute, Boulder, Colo. "However, if...

JPL -- A study by NASA and university scientists is shedding new light on a mysterious, cyclical wave in Earth's atmosphere that at times profoundly affects our planet's weather and climate. Using satellite data from the Atmospheric Infrared Sounder (Airs) instrument on NASA's Aqua spacecraft, a research team led by Dr. Duane Waliser of NASA's Jet Propulsion Laboratory, Pasadena, Calif., and Dr. Baijun Tian of the California Institute of Technology, also in Pasadena,, set out to study the...

JPL -- The joint NASA/Centre National d'Etudes Spatiales Topex/Poseidon oceanography satellite ceased operations after nearly 62,000 orbits of Earth. The spacecraft lost its ability to maneuver, bringing to a close a successful 13-year mission. "Topex/Poseidon revolutionized the study of Earth's oceans, providing the first continuous, global coverage of ocean surface topography and allowing us to see important week-to-week oceanic variations," said Dr. Mary Cleave, associate administrator...
