JPL PAST Missions http://www.jpl.nasa.gov/missions/past_missions.cfm JPL CURRENT Missions http://www.jpl.nasa.gov/missions/index.cfm NASA CURRENT Missions http://www.nasa.gov/missions/current/index.html Aqua -was the first member launched of a group of satellites termed the Afternoon Constellation, or sometimes the A-Train.  JASON-Is an ocean surface mapper. It was the first to successfully complete the TOPEX/poseidon mission and enabled scientists to forecast the 1997-1998 El Nino.

•  Aura- The Aura satellite is a tool that scientists use to check out our ozone layer. It was launched on July, 15th, 2004. CALIPSO- CALIPSO provides the role that clouds and airborne particles play in regulating Earth's weather, climate, and air quality. CALIPSO is a joint mission between NASA and CNES, the French space agency. It was launched april 28th, 2006.

Terra has been collecting data about Earth's changing climate. Terra carries five state-of-the-art sensors that have been studying the interactions among the Earth's atmosphere, lands, oceans, and radiant energy. Each sensor has unique design features that will enable scientists to meet a wide range of science objectives. The five onboard Terra sensors are: -ASTER -CERES -MISR -MODIS -MOPITT

The Terra spacecraft was launched on December 18, 1999, weighing 10,506 pounds (4,645 kg). || Image of Hurricane Lane over Mexico taken from the Terra satellite on September 15, 2006. Image credit: NASA

 * CloudSat** is the first spacecraft to study clouds on a global basis. The mission will use an advanced radar to "slice" through clouds to see their vertical structure, providing a completely new observational capability from space (current weather satellites can only image the uppermost layers of clouds). CloudSat's primary goal is to furnish data needed to evaluate and improve the way clouds are represented in global models, thereby contributing to better predictions of clouds and thus to their poorly understood role in climate change and the cloud-climate feedback.

[|Baghdad, Iraq]Current events make war-torn Baghdad a staple of today's news. The city is the capital of Iraq and the most populous city in the country.

In 1975, NASA Administrator Dr. James Fletcher predicted that if one space age development would save the world, it would be **Landsat** and its successor satellites. Since the early 1970s, Landsat has continuously and consistently archived images of Earth; this unparalleled data archive gives scientist the ability to take pictures of changes in Earth’s landscape. For 34 years, the Landsat program has collected information from Earth’s surface, creating a historical archive unmatched in quality, detail, coverage, and length

"The Landsat program was created in the United States in the heady scientific and exploratory times associated with taming the atom and going to the Moon." - Dr. John Barker
