GREENBELT, Maryland -- NASA and the Japan Aerospace Exploration
Agency (JAXA) launched an Earth-observing satellite at 1:37 p.m. EST on Thursday from Japan to observe and measure precipitation in the Arctic and Antarctic
Circles.
The four-ton Global Precipitation Measurement (GPM) Core Observatory was launched aboard a Japanese H-IIA rocket from
Tanegashima Space Center on Tanegashima Island in southern Japan.
"With this launch, we have taken another giant leap in providing the
world with an unprecedented picture of our planet's rain and snow," said
NASA Administrator Charles Bolden. "GPM will help us better understand
our ever-changing climate, improve forecasts of extreme weather events
like floods, and assist decision makers around the world to better
manage water resources."
According to NASA, the GPM Core Observatory will take a major step in improving upon the
capabilities of the Tropical Rainfall Measurement Mission (TRMM), a
joint NASA-JAXA mission launched in 1997 and still in operation. While
TRMM measured precipitation in the tropics, the GPM Core Observatory
expands the coverage area to Earth's polar regions.
The GPM Core Observatory is the first of NASA's five Earth science
missions launching this year.
