NASA’s newest Earth observation satellite launched Saturday aboard a Boeing Delta II rocket. Called Aqua, the satellite will gather data about global precipitation, evaporation and the cycling of water to help scientists understand if there’s any acceleration of the Earth’s water cycle and due to changing climate. The infrared sounder on board will measure the Earth’s atmosphere and help improve weather prediction.

NASA’s latest Earth observing satellite, Aqua, carrying the NASA Jet Propulsion Laboratory-managed Atmospheric Infrared Sounder instrument, successfully launched this morning at 2:55 a.m. Pacific Time. Aqua is dedicated to advancing our understanding of Earth’s water cycle and our environment. Launching the Aqua spacecraft marks a major milestone in support of NASA’s mission to help us better understand and protect our planet.

The Aqua spacecraft lifted off from the Western Test Range of Vandenberg Air Force Base, Calif., aboard a Delta II rocket. Spacecraft separation occurred at 3:54 a.m. Pacific Time, inserting Aqua into a 705-kilometer (438-mile) orbit.

“The Aqua project has truly been a team effort and we are very excited this morning,” said Aqua project manager Phil Sabelhaus at NASA’s Goddard Space Flight Center, Greenbelt, Md.

The primary goal of Aqua, as the name implies, is to gather information about water in Earth’s system. Equipped with six state-of-the-art instruments, Aqua will collect data on global precipitation, evaporation and the cycling of water. This information will help scientists all over the world to better understand Earth’s water cycle and determine if the water cycle is accelerating as a result of climate change.

JPL’s Atmospheric Infrared Sounder will measure Earth’s atmosphere and surface, allowing scientists to improve weather prediction and observe changes in Earth’s climate.

Aqua is the latest in a series of Earth Observing System spacecraft, following the Terra satellite launched in December 1999. Aqua will cross the equator daily at 1:30 p.m. as it heads north. The early afternoon observation time contrasts with the Terra satellite, which crosses the equator between 10:30 and 10:45 a.m. daily. Aqua’s afternoon observations, combined with Terra’s morning observations, will provide important insights into the daily cycling of key scientific parameters such as precipitation and ocean circulation.

Aqua is a joint project among the United States, Japan and Brazil. The United States provided the spacecraft and four of the six scientific instruments. In addition to the JPL-provided Atmospheric Infrared Sounder, the other U.S. instruments include the Moderate Resolution Imaging Spectroradiometer and the Advanced Microwave Sounding Unit, both provided by the Goddard center, and the Clouds and the Earth’s Radiant Energy System, provided by NASA’s Langley Research Center, Hampton, Va.

Japan’s National Space Development Agency provided the Advanced Microwave Scanning Radiometer, while the Instituto Nacional de Pesquisas Espaciais (the Brazilian Institute for Space Research) provided the Humidity Sounder for Brazil.

Aqua is part of NASA’s Earth Science Enterprise, a long-term research effort dedicated to understanding and protecting our home planet. Through the study of Earth, NASA will help to provide sound science to policy and economic decision makers so as to better life here, while developing the technologies needed to explore the universe and search for life beyond our home planet.

After much anticipation, an Ariane 5 rocket blasted off from Kourou, French Guiana last night, carrying the European Space Agency’s Envisat environmental monitoring satellite into an 800km orbit. Once it reaches its final orbit, the 8000 kg Envisat will observe the Earth’s environment using ten instruments which measure the state of the land, ocean, ice cover and atmosphere. This is the first launch of an Ariane 5 since a problem last July that placed two satellites into incorrect orbits.

The eagerly awaited launch of ESA?s Envisat environmental monitoring satellite took place in Kourou, French Guiana, today at 22:07:59 hrs Kourou time (02:07:59 hrs CET). Envisat?s spectacular night-time launch also marked the return to business for Europe?s Ariane 5 launcher.

Lift-off was witnessed by dozens of cheering engineers, scientists and project members at the launch site and at ESA centres across Europe. Rising into a clear sky, the Ariane 5 propelled the Envisat towards a lofty vantage point some 800 km above the Earth?s surface.

Envisat ? the most ambitious Earth observation satellite ? follows in the footsteps of ESA?s successful ERS-1 and ERS-2 missions launched in the 1990s. It will boost Europe?s capacity to take part in the study of the Earth and its environment by supporting critical research programmes on global warming and climate change issues, as well as performing crucial tasks such as pollution and disaster monitoring .

After a flawless lift-off, the Ariane 5 placed Envisat into sun-synchronous orbit, allowing ESA ground controllers at the space operations centre in Darmstadt, Germany, to take full control for the first time of the most complex satellite ever built in Europe.

?This has been a particularly exciting day for ESA and the European space community as a whole,? said Jos? Achache, ESA?s Director of Earth Observation. ?Europe is taking an important lead in global observations for worldwide environmental needs and Envisat is going to make a significant impact on the future of remote sensing of the Earth?.

?The ten instruments on board Envisat, more than on any other satellite, cover a wide spectrum of phenomena, delivering evidence of the interactions between the atmosphere, the ocean, the polar ice caps, the vegetation as well as human activity at the surface of the Earth. We will be able to trace the smallest changes to the Earth?s surface anywhere on the globe. The importance of this mission has triggered great interest in the Earth-science community, both at a European level and worldwide.?

Commenting from Europe?s spaceport in French Guiana, Jacques Louet, ESA?s Envisat Programme Manager, admitted that there was a certain risk to pack so much know-how into just one satellite. ?However, if we want to have a comprehensive understanding, we must follow this path?, he said.

Given its sheer size, Envisat has involved almost all of Europe?s space industries in the development of numerous advanced technologies, particularly for the payload.

Envisat is expected to be declared operational after just a few weeks, once its payload has been checked out and the various data-recovery links set up. Then the satellite?s six-month long commissioning phase will begin, ensuring that the ten instruments are operating as specified and that we can start delivering validated products to our users.

?Now Envisat is in orbit, the culmination of many years? work really begins and we are looking forward to the environmental benefits the satellite is going to bring to Europe,? added Mr Achache.

The successful launch of Envisat also marked a return to service for the Ariane 5 launcher. It?s upper stage has undergone over 300 tests since last summer, following the failure of flight Ariane 510 to insert two satellites, including ESA?s Artemis, in the correct orbits. However, thanks to ion propulsion, the Artemis mission is turning into a success story, as the satellite is making its way to geostationary orbit, and nominal operations could start this summer.
