This is a 15 second Instagram video about NASA's Tropical Rainfall Measuring Mission (TRMM) satellite. On July 8, TRMM's fuel tank indicated that the satellite was nearly at the end of its fuel supply. NASA has ceased maneuvers to keep the satellite at its operating altitude of 402 kilometers. With its speed decreasing, TRMM has begun to drift downward. As it slowly descends towards Earth, in the next two to three years, it will continue to collect useful data.
