Janet Anderson and Jessica Eagan, NASA's Marshall Space Flight Center Keeping a spare on hand simply makes sense. Just as drivers keep spare tires on hand to replace a flat or blowout, NASA routinely maintains “spares,” too. These flight hardware backups allow NASA to seamlessly continue work in the unlikely event something goes down for a repair. When projects end, these handy spares can sometimes find second lives in new areas for use. Researchers at NASA’s Marshall Space Flight...

WASHINGTON, Sept. 8, 2014 /PRNewswire-USNewswire/ -- The launch of a NASA ocean winds sensor to the International Space Station (ISS) this month inaugurates a new era of Earth observation that will leverage the space station's unique vantage point in space. Before the end of the decade, six NASA Earth science instruments will be mounted to the station to help scientists study our changing planet. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The first NASA Earth-observing...

GPM Core Observatory data
2014-09-04 12:21:29

WASHINGTON, Sept. 4, 2014 /PRNewswire-USNewswire/ -- The most accurate and comprehensive collection of rain, snowfall and other types of precipitation data ever assembled now is available to the public. This new resource for climate studies, weather forecasting, and other applications is based on observations by the Global Precipitation Measurement (GPM) Core Observatory, a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA), with contributions from a constellation of...

Rani Gran, NASA's Goddard Space Flight Center Pressure readings from the Tropical Rainfall Measuring Mission's (TRMM) fuel tank on July 8 indicated that the satellite was nearly at the end of its fuel supply. As a result, NASA has ceased maneuvers to keep the satellite at its operating altitude of 402 kilometers (~250 miles). With its speed decreasing, TRMM has begun to drift downward. A small amount of fuel remains to conduct debris avoidance maneuvers to ensure the satellite remains...

NASA Aircraft Concludes Ground Validation And Hydrology Campaign
2014-06-19 03:52:05

NASA A NASA high-altitude ER-2 aircraft concluded its participation June 16 in a study aimed at gaining a better understanding of precipitation over mountainous terrain. The Integrated Precipitation and Hydrology Experiment, or IPHEx, field campaign is part of the ground validation effort for the Global Precipitation Measurement (GPM) mission, an international satellite mission led by NASA and the Japan Aerospace Exploration Agency. GPM's Core Observatory launched Feb. 27, 2014, to...

New NASA/JAXA Global Precipitation Measurement Satellite Passes Check-out, Starts Mission
2014-06-02 03:00:25

Ellen Gray, NASA The new Global Precipitation Measurement Core Observatory satellite is now in the hands of the engineers who will fly the spacecraft and ensure the steady flow of data on rain and snow for the life of the mission. The official handover to the Earth Science Mission Operations team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, on May 29, marked the end of a successful check-out period. The Global Precipitation Measurement (GPM) mission is a joint...

April Flowers for redOrbit.com - Your Universe Online The first images captured by the newest Earth-observing satellite operated as a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA) have been released. The images are from the Global Precipitation Measurement (GPM) Core Observatory, which launched on February 27 of this year. The focus of the image set covers precipitation falling inside a cyclone that occurred on March 10 over the northwest Pacific Ocean,...

NASA Helps Improve Flood Safety When Waters Rise
2014-03-20 14:42:10

NASA Flooding is the most frequent and widespread weather-related natural disaster, taking a huge toll in lives and property each year. NASA Earth-observing satellites and airborne missions provide vital information to emergency planners, relief organizations and weather forecasters, helping to improve flood monitoring and forecasting, as well as providing a more comprehensive understanding of one of Mother Nature's most damaging hazards. NASA's Earth-observing satellites provide...

NASA's TRMM Satellite Images Show System That Soaked California

[ Watch The Video: TRMM Sees California Storm Move East ] Harold F. Pierce, NASA The Tropical Rainfall Measuring Mission or TRMM satellite provided a look at the rainfall associated with the large storm system that brought soaking rains to California on Feb. 28 and Mar. 1. Satellite imagery created at NASA shows the movement of the storm from the US West Coast to the East Coast. At NASA's Goddard Space Flight Center in Greenbelt, Md. images were created using data from the TRMM...

April Flowers for redOrbit.com - Your Universe Online Just as you might keep a spare tire in your car, or a spare filter for your air conditions, NASA keeps spares as well. These "spare" flight hardware units allow NASA to continue work without interruption in the event that something goes down for repair. These spare parts are kept even after the project ends, sometimes finding second lives in new areas. A sophisticated piece of flight hardware, called a Lightning Imaging Sensor (LIS),...
