Mission Status Report PASADENA, Calif. – Excellent launch precision for NASA’s Mars Science Laboratory mission has forestalled the need for an early trajectory correction maneuver, now not required for a month or more. That first of six planned course adjustments during the 254-day journey from Earth to Mars had originally… Read more“Mars Science Laboratory Mission Status Report: Course Excellent, Adjustment Postponed”

Herschel Space Observatory Finds Oceans of Water in Disk of Nearby Star
PASADENA, Calif. — Using data from the Herschel Space Observatory, astronomers have detected for the first time cold water vapor enveloping a dusty disk around a young star. The findings suggest that this disk, which is poised to develop into a solar system, contains great quantities of water, suggesting that… Read more“Herschel Space Observatory Finds Oceans of Water in Disk of Nearby Star”
Arctic Sea Ice Continues Decline, Hits 2nd-Lowest Level
Last month the extent of sea ice covering the Arctic Ocean declined to the second-lowest extent on record. Satellite data from NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder showed that the summertime sea ice cover narrowly avoided a… Read more“Arctic Sea Ice Continues Decline, Hits 2nd-Lowest Level”

PASADENA, Calif. – NASA’s new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission’s anticipated discoveries. Aquarius, which is aboard the Aquarius/SAC-D (Satélite de Aplicaciones Científicas) observatory, is making NASA’s first space observations of ocean surface salinity… Read more“The first global map of the salinity, or saltiness, of Earth’s ocean surface produced by NASA’s new Aquarius instrument reveals a rich tapestry of global salinity patterns, demonstrating Aquarius’ ability to resolve large-scale salinity distribution features clearly and with sharp contrast.

NASA’s UARS Re-enters Earth’s Atmosphere
NASA’s decommissioned Upper Atmosphere Research Satellite (UARS) fell back to Earth between 11:23 p.m. EDT Friday, Sept. 23 and 1:09 a.m. Sept. 24, 20 years and nine days after its launch on a 14-year mission that produced some of the first long-term records of chemicals in the atmosphere. The precise… Read more“NASA’s UARS Re-enters Earth’s Atmosphere”
NASA’s Kepler Mission Discovers a World Orbiting Two Stars
The existence of a world with a double sunset, as portrayed in the film Star Wars more than 30 years ago, is now scientific fact. NASA’s Kepler mission has made the first unambiguous detection of a circumbinary planet — a planet orbiting two stars — 200 light-years from Earth. Unlike… Read more“NASA’s Kepler Mission Discovers a World Orbiting Two Stars”
