TRMM Out Of Fuel, Continues to Provide Data
Pressure readings from the Tropical Rainfall Measuring Mission's (TRMM) fuel tank on July 8 indicated that the satellite was nearly at the end of its fuel supply. As a result, NASA has ceased maneuvers to keep the satellite at its operating altitude of 402 kilometers (~250 miles). With its speed decreasing, TRMM has begun to drift downward. A small amount of fuel remains to conduct debris avoidance maneuvers to ensure the satellite remains safe. Artist's visualization of the TRMM satellite in space over a tropical cyclone.

JAXA Launches GCOM-W1 Satellite

Congratulations to our partner, the Japan Aerospace Exploration Agency (JAXA), for the successful launch yesterday of the Global Change Observation Mission 1st - Water (GCOM-W1). GCOM-W1 carries the Advanced Microwave Scanning Radiometer 2 (AMSR2) which successfully deployed its antenna on orbit. AMSR2 will detect microwave radiation to measure sea surface temperature, sea surface wind speed, sea ice concentration, snow depth, soil moisture, water vapor, cloud liquid water, and precipitation. GCOM-W1 will be a part of the GPM constellation, contributing its measurements to the GPM global data

Diagram of the GPM Core Observatory Carrying both a dual frequency radar instrument and a passive microwave radiometer, the Core Spacecraft serves as a calibration standard for the other members of the GPM spacecraft constellation. The Core Spacecraft was developed and tested in-house at NASA Goddard Space Flight Center. The GPM Core Observatory orbit inclination of 65 degrees is such that it enables the orbit to cut across the orbits of other microwave radiometers, sample the latitudes where nearly all precipitation occurs, and sample at different times of day. The GPM Core Observatory GMI...
