LIGHTNING STRIKING
The Tropical Rainfall Measuring Mission (TRMM), a joint mission between NASA and the Japan Aerospace Exploration (JAXA) Agency to study rainfall for weather and climate research, officially came to an end on April 15, 2015 (see http://pmm.nasa.gov/trmm/mission-end ).
Launched in November 1997, with a design lifetime of 3 years, TRMM produced over 17 years of valuable scientific data. TRMM carried 5 instruments: a 3-sensor rainfall suite (PR, TMI, VIRS) and 2 related instruments (LIS and CERES).
