Latest Upper Atmosphere Research Satellite Stories
NASA on Wednesday said that a 20-year-old satellite is due to re-enter Earth’s atmosphere sometime in the next six weeks, burn up, and rain debris over a wide area. The defunct 7-ton Upper Atmosphere Research Satellite (UARS) should plunge to Earth sometime in late September or early October, but the agency cannot determine exactly when that re-entry will occur and what geographic area may be affected. However, NASA is keeping a close eye on the satellite and will keep the public...
NASA will host a media teleconference at 11 a.m. EDT on Friday, Sept. 9, to discuss the anticipated re-entry of the agency's decommissioned Upper Atmosphere Research Satellite (UARS). Re-entry is expected late this month or early October. The teleconference participants are: -- Paul Hertz, chief scientist, NASA's Science Mission Directorate, Washington -- Nick Johnson, chief scientist, NASA's Orbital Debris Program, Johnson Space Center, Houston -- U.S. Air Force Maj. Michael W....

Two satellite instruments aboard NASA's Solar Radiation & Climate Experiment (SORCE) mission -- the Total Solar Irradiance Monitor (TIM) and the Solar Irradiance Monitor (SIM) -- have made daily measurements of the sun's brightness since 2003.The two instruments are part of an ongoing effort to monitor variations in solar output that could affect Earth's climate. Both instruments measure aspects of the sun's irradiance, the intensity of the radiation striking the top of the...
DURHAM, N.C. -- At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities, two Duke University physicists report. The physicists said that their findings indicate that climate models of global warming need to be corrected for the effects of changes in solar activity. However, they emphasized that their findings do not argue...
JPL -- A NASA satellite that measures the variability in the amount of the Sun's energy that reaches Earth's atmosphere and impacts our winds, land and oceans has successfully accomplished its five-year primary mission. The Active Cavity Radiometer Irradiance Monitor satellite, or AcrimSat, which was launched in December 1999, carries the Acrim III instrument. The instrument is the third in a series of solar-monitoring tools built by NASA's Jet Propulsion Laboratory, Pasadena, Calif., and...

Atlantis launched from Kennedy Space Center on November 3, 1994 at 11:59 AM EST and landed at Edwards AFB on November 14 at 7:33 AM PST. The shuttle orbited 174 times at an altitude of 164 nautical miles at an inclination of 57 degrees and travelled 4.5 million miles. The mission lasted 10 days, 22 hours, 34 minutes, and 2 seconds. This mission further advanced efforts to collect data about sun's energy output, chemical makeup of the Earth's middle atmosphere, and how these factors affect...
Discovery launched from Kennedy Space Center on September 12, 1991 at 7:11 PM EDT and landed at Edwards AFB on September 18 at 12:38 AM PDT. The shuttle orbited 81 times at an altitude of 313 nautical miles at an inclination of 57 degrees and travelled 2.2 million miles. The mission lasted 5 days, 8 hours, 27 minutes, and 38 seconds. A satellite was launched to study the upper atmosphere and ozone layer. The Upper Atmosphere Research Satellite (UARS), was deployed on the third day of...
