NASA | Zebra Crossing

Botswana's Okavango Delta and the Makgadikgadi Salt Pans are two ends of a 360-mile round trip zebra migration, the second longest on Earth. In this animation, shades of red show dry areas, green represents vegetation, and the dots show GPS tracked zebras. The zebras begin at the Okavango Delta in late September. After the dry Southern hemisphere winter, November rains signal it is time to begin their two-week journey to the Salt Pans. The zebras feast on nutrient-rich grasses all summer, and return to the Delta as the rain peters out in April.

Fences blocked this zebra migration from 1968...

Researchers need accurate and timely rainfall information to better understand and model where and when severe floods, frequent landslides and devastating droughts may occur. GPM's global rainfall data will help to better prepare and respond to a wide range of natural disasters.

The Global Precipitation Measurement (GPM) is an international satellite mission to provide next-generation observations of rain and snow worldwide every three hours. NASA and the Japan Aerospace Exploration Agency (JAXA) will launch a "Core" satellite carrying advanced instruments that will set a new standard for precipitation measurements from space. The data they provide will be used to unify precipitation measurements made by an international network of partner satellites to quantify when, where, and how much it rains or snows around the world.

The GPM mission...

The GPM mission will help advance our understanding of Earth's water and energy cycles, improve the forecasting of extreme events that cause natural disasters, and extend current capabilities of using satellite precipitation information to directly benefit society.

NASA | For Good Measure

The need for measuring the when and where and how much of precipitation goes beyond our weekend plans. We also need to know precipitaiton on a global scale. Rain gauges and radars are useful but are inconsistent and do not cover enough of the globe to provide accurate precipitation rates. The GPM constellation will cover the globe and give us a more comprehensive look at precipitation.

NASA | GPM Enters Thermal Vacuum Chamber

On Tuesday Nov. 13, 2012, the GPM core observatory was moved
from the clean room to the thermal vacuum chamber. The spacecraft, wrapped in
protective blankets, made the short trip by crane across the testing facility
where it was then lowered into the 40-foot (12 meter) diameter test chamber.
