Tropical Rainfall Measuring Mission (TRMM)
Mission Category: Precipitation Missions
Launch Date: November 27, 1997
Launch Location: Tanegashima Space Center, Japan
Designed Life: November 27, 2000
The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA). It was designed to monitor and study tropical rainfall and the associated release of energy that helps to power the global atmospheric circulation, shaping both weather and climate around the globe.
TRMM was originally designed to carry out a three-year mission, but has operated successfully for over eight years. TRMM completed all of its research and technology objectives by 2001, and provided data used worldwide in the monitoring and forecasting of hazardous weather on a demonstration basis . NASA and the Japan Aerospace Exploration Agency (JAXA) stopped TRMM’s science operations and data collection on April 8, 2015 after the spacecraft depleted its fuel reserves.
