and no further recovery attempts are planned. Atmospheric Infrared Sounder (AIRS) — measures atmospheric temperature and humidity, land and sea surface temperatures. Cooler A telemetry became frozen on March 24, 2014, but this had no impact on science gathering. On September 25, 2016, Cooler-A experienced a shut down anomaly. Anomaly recovery occurred two days later and also cleared a condition that had disabled Cooler-A telemetry since the 2014 Cooler-A anomaly. Humidity Sounder for Brazil (HSB) — VHF band equipment measuring atmospheric humidity. Furnished by Instituto Nacional de Pesquisas Espaciais of Brazil. The HSB instrument has been in survival mode, and thus non-operational, since February 5, 2003, when the scan mirror motor failed. Clouds and the Earth's Radiant Energy System (CERES) — Flying Modules 3 and 4, measure broadband radiative energy flux. CERES' shortwave channel on module 4 failed on March 30, 2005, but its two other channels remain operational. The Aqua spacecraft has a mass of about , plus propellant of about at launch. Stowed for launch, the satellite fit in a volume of 2.68 m x 2.49 m x 6.49 m. Deployed, Aqua is 4.81 m x 16.70 m x 8.04 m.
