The launch of NASA’s Aqua EOS PM spacecraft aboard a Boeing Delta II
rocket is scheduled to occur on Saturday, May 4 from Space Launch
Complex 2 at Vandenberg Air Force Base, Calif. Launch is targeted to
occur at 2:55 a.m. PDT during a 10-minute launch window. Aqua will be
launched into a 428-mile-high polar orbit at an inclination of 98.2
degrees, orbiting the earth every 99 minutes. The entire surface of
the Earth will rotate beneath the spacecraft every 16 days.

The primary role of the 6,248-pound Aqua spacecraft is to gather
information about the Earth’s water cycle. Information the spacecraft
gathers will help the world’s scientists determine if the cycle of
Earth’s water is being affected by climate change. The data emphasis
will be on atmospheric water vapor, water droplets contained in
clouds, ice crystals, sea ice including icebergs, as well as water in
the oceans and on land including glaciers. Scientists may then
understand the change in Earth bio-systems dependent on water such as
growth of vegetation on land and phytoplankton in the oceans. The data
will also be useful in long-term weather forecasting and understanding
character of severe storms. The Aqua mission is planned to last
six years.
