Guy Webster / Dwayne Brown - NASA's Jet Propulsion Laboratory NASA's Mars Odyssey spacecraft has tweaked its orbit to help scientists make the first systematic observations of how morning fogs, clouds and surface frost develop in different seasons on the Red Planet. The maneuver took place Tuesday, Feb. 11. Odyssey team engineers at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and Lockheed Martin Space Systems of Denver, designed the gentle move to accelerate Odyssey's drift...

MESSENGER carries a Gamma-Ray Spectrometer (GRS) that is capable of measuring and characterizing gamma-ray emissions from the surface of Mercury. Just like radio waves, visible light, and X-rays, gamma rays are a form of electromagnetic radiation, but with higher energies than those other types of radiation. Gamma rays coming from Mercury carry information about the concentrations of elements present on its surface, so observations from the MESSENGER GRS are being used to determine the...

The new project manager for the longest-working spacecraft currently active at Mars, NASA's Mars Odyssey, has a long track record himself.He is Gaylon McSmith, a former pilot of U.S. Air Force fighter jets and Continental Airlines airliners. At NASA's Jet Propulsion Laboratory, Pasadena, Calif., he has been a leader on the Odyssey team since two months after the spacecraft began orbiting Mars in October 2001.On Dec. 15 of this year, Odyssey will break the record for the longest-working...

Experiments by British scientists could reveal the make-up of the universe, the University of Liverpool said Thursday. The examinations will become part of the Advanced Gamma Tracking Array experiment, which seeks to create a so-called fingerprint of the inside of the atomic nucleus to help scientists understand the universe's structure, including humans and stars, the university said in a release. Scientists will analyze particle interactions that produce gamma rays, the university said, and...

The detectors will become part of the Advanced Gamma Tracking Array (AGATA) experiment, currently based in Italy, which aims to create a 'fingerprint' of the inside of the atomic nucleus to understand the structure of all matter in the Universe, including human beings and the stars.The experiment will help scientists analyse particle interactions that produce gamma rays, which are also commonly used for their penetrating properties in medical diagnostics and treatments such as PET scans and...

The U.S. space agency has nudged the Mars Odyssey spacecraft's orbit, allowing it to look at the day side of Mars in mid-afternoon instead of late afternoon. NASA said the change, which took eight months to complete, increases the sensitivity for infrared mapping of Martian minerals. Orbit design for Odyssey's first seven years of observing Mars used a compromise between what worked best for the infrared mapping and for another onboard instrument, officials said. The orbiter is now overhead...

NASA's long-lived Mars Odyssey spacecraft has completed an eight-month adjustment of its orbit, positioning itself to look down at the day side of the planet in mid-afternoon instead of late afternoon. This change gains sensitivity for infrared mapping of Martian minerals by the orbiter's Thermal Emission Imaging System camera. Orbit design for Odyssey's first seven years of observing Mars used a compromise between what worked best for the infrared mapping and for another onboard instrument....

As much as a third of Mars could have been underwater, UA scientists say An international team of scientists who analyzed data from the Gamma Ray Spectrometer onboard NASA's Mars Odyssey reports new evidence for the controversial idea that oceans once covered about a third of ancient Mars. "We compared Gamma Ray Spectrometer data on potassium, thorium and iron above and below a shoreline believed to mark an ancient ocean that covered a third of Mars' surface, and an inner shoreline believed...
