NASA ISS-RapidScat Built On The Fly
2013-10-30 11:52:06

Brett Smith for redOrbit.com - Your Universe Online The best chefs in the world can create a gourmet dish from leftover ingredients and NASA scientists have set out to show they can accomplish a similar feat though the ISS-RapidScat science mission. An abbreviated form of Rapid Scatterometer, ISS-RapidScat was fashioned from spare parts and put together on a relatively short time scale. The mission will monitor ocean winds from the International Space Station. Scientists study ocean...

Seasat Blazed The Trail For Many Mission
2013-06-28 05:27:14

April Flowers for redOrbit.com - Your Universe Online Even if they don't last long, history tends to look fondly upon trailblazers. Thirty-five years ago this week, NASA's Jet Propulsion Laboratory (JPL) launched an experimental satellite called Seasat, with the mission to study Earth and its seas. An unexpected malfunction ended the mission after just 106 days, leading some to look on the satellite as a failure. Seasat is still in orbit, however, shining in the night sky at magnitude...

Ocean Winds To Be Monitored From The International Space Station
2013-01-30 07:48:19

April Flowers for redOrbit.com - Your Universe Online NASA will launch the ISS-RapidScat instrument to the International Space Station (ISS) in 2014. Reusing hardware built to test parts of the QuikScat satellite, the new instrument will measure ocean-surface wind speed and direction. ISS-RapidScat will help improve weather forecasts here on Earth, including hurricane monitoring, and will further scientific understanding of how ocean-atmosphere interactions influence Earth's climate....

Amazon Rainforest Under Threat From Climate Change
2013-01-18 06:36:22

April Flowers for redOrbit.com - Your Universe Online A megadrought that started in 2005 is still affecting a portion of the Amazon Rainforest twice the size of California, a new study led by NASA's Jet Propulsion Laboratory (JPL) finds. The results of this study, combined with the observed recurrences of droughts every few years and associated damage to forests in both the southern and western Amazon over the past decade, reveal that the rainforest might be showing the initial signs of...

Over 30 Years Of Global Soil Moisture Observations For Climate Applications
2012-06-20 04:14:52

[ Watch the Video ] Water held in soil plays an important role in the climate system. The dataset released by ESA is the first remote-sensing soil moisture data record spanning the period 1978 to 2010 — a predecessor of the data now being provided by ESA´s SMOS mission. The datasets are now available to the science community for feedback analyses and climate model validation. The amount of water held in global soils makes up only about 0.001% of the total water found on...

Written by Rosemary Sullivant, NASA/JPL The breakthrough moment for oceanographer Gary Lagerloef, the principal investigator for NASA's new Aquarius mission, came in 1991. That's when he knew it would be possible to make precise measurements of ocean salinity from space. It has taken nearly two decades to turn that possibility into a reality. Lagerloef was looking at data collected by a NASA aircraft flying over the ocean off the coast of Maryland. It was testing a new radiometer, an...

Melissa Quijada, NASA Goddard Space Flight Center, Greenbelt, Md. With more than a few stamps on its passport, NASA's Aquarius instrument on the Argentinian Sat©lite de Aplicaciones Científicas (SAC)-D spacecraft will soon embark on its space mission to "taste" Earth's salty ocean. After a journey of development and assembly through NASA facilities, a technology center in Bariloche, Argentina, and testing chambers in Brazil, the Aquarius instrument, set to measure the...

Earth has a limited amount of water that recycles itself in what is called the "Ëœwater cycle'. Climate change, weather and human life are highly affected by changes in this continuous, interconnected cycle. Observing and monitoring the key variables governing the global water cycle is essential to our understanding of the Earth's climate, forecasting our weather, predicting floods and droughts, and improving water management for human use. Recent advances in Earth observation (EO)...

NASA mission managers are assessing options for future operations of the venerable QuikScat satellite following the age-related failure of a mechanism that spins the scatterometer antenna. This spinning antenna had been providing near-real-time ocean- surface wind speed and direction data over 90 percent of the global ocean every day. In recent months, the QuikScat project team has been monitoring a pattern of increasing friction in the bearings that allow the antenna to spin, leading to...

A small NASA aircraft completed its first successful science flight Thursday as part of an expedition to study the receding Arctic sea ice and improve understanding of its life cycle and the long-term stability of the Arctic ice cover. The mission continues through July 24. NASA's Characterization of Arctic Sea Ice Experiment, known as CASIE, began a series of unmanned aircraft system flights in coordination with satellites. Working with the University of Colorado and its research partners,...
