NASA and its international partners operate several Earth-observing satellites that closely follow one after another along the same orbital “track.” This coordinated group of satellites, constituting a significant subset of NASA’s current operating major satellite missions, is called the Afternoon Constellation, or the A-Train, for short. The satellites are in a polar orbit, crossing the equator northbound at about 1:30 p.m. local time, within seconds to minutes of each other. This allows near-simultaneous observations of a wide variety of parameters to aid the scientific community in advancing our knowledge of Earth-system science and applying this knowledge for the benefit of society. Five satellites currently fly in the A-Train: GCOM-W1, Aqua, CALIPSO, CloudSat, and Aura. On November 16, 2011, PARASOL was lowered to 9.5 km under the A-Train and on December 18, 2013 PARASOL ceased operation, fully exiting the A-Train.

OCO-2 joined the configuration in July 2014.

Consider the Existing Earth Science Missions

The data and Earth observation/monitoring are the resources our generation is passing forward to future generations

The goal is to provide the capabilities to make informed decisions and shape intelligent policies to protect and preserve security
