The mineral-mapping instrument on NASA's Mars Reconnaissance Orbiter has successfully removed its lens cover and is ready to start observing the planet. The cover protected the lens of the Compact Reconnaissance Imaging Spectrometer for Mars while the spacecraft was shrinking its orbit by repeatedly dipping into Mars' atmosphere.
Cassini successful flew by Titan on Saturday, Sept. 23. Data collected will help scientists study the composition at the very highest levels of Titan's atmosphere.
Cassini's next close flyby of Titan will be on Saturday, Sept. 23. This will be one of Cassini's closest flybys yet of Titan, at just 960 kilometers (600 miles) above the surface. Scientists will use the observations to study the composition at the very highest levels of Titan's atmosphere.
JPLers turned out Monday to give a sendoff to Nobel laureate Dr. David Baltimore, who retired this month as president of the California Institute of Technology, the Laboratory's parent institution, after nine years in that post. Baltimore will continue teaching and research as a member of the Caltech faculty.› View larger image
Ring scientists have been waiting for this. Finally, after more than two years orbiting Saturn, the Cassini spacecraft reaches one of the ultimate vantage points.
A new name has been bestowed on the "dwarf planet" whose discovery in 2005 rocked the solar system.
Cassini's visual and infrared mapping spectrometer has detected what appears to be a massive ethane cloud surrounding Titan's north pole. The cloud might be snowing ethane snowflakes into methane lakes below.
NASA-funded researchers, including JPL's Wes Traub, have outlined six stages of Earth's life history, which might help identify life elsewhere in the universe.
Using a network of small, automated telescopes, NASA-funded astronomers have found an odd, bloated planet orbiting one member of a pair of distant stars.
A rare planet circling a star 500 light-years away has been spotted by astronomers using a telescope whose development was funded by NASA.
Cassini flew by Saturn's moon Titan on Sept. 7, 2006, studying its atmosphere and surface.
The collapse of the World Trade Center on September 11, 2001, and the fires that followed produced a noxious smoke plume, a complex mixture of tiny airborne particles and gases.
After revealing a land of bountiful lakes on Cassini's last flyby of Saturn's moon Titan, the journey continues during a flyby on Sept. 7, 2006.
Step outside 45 minutes before sunrise Aug. 20 to 22. The celestial view is well worth an early wake up.
When kids head back to school this fall, they might have some brand new planets to memorize. The International Astronomical Union, currently meeting in Prague, is expected to vote on the definition of a planet.
Voyager 1, already the most distant human-made object in the cosmos, reaches 100 astronomical units from the sun on Tuesday, August 15 at 5:13 p.m. Eastern time (2:13 p.m. Pacific time).
Not many teenagers can say they've worked on an instrument that will fly in space.
Kerry Erickson is mission operations and project manager for the Galaxy Evolution Explorer, which is on a mission to do a nearly complete sky survey.
A new false-colored image from NASA's Hubble, Chandra and Spitzer space telescopes shows a giant jet of particles that has been shot out from a quasar.
If you want to be an inspirational teacher, it's not hard: You have to be inspired yourself.
