Earth Observation System
Series of 3 satellites for scientific applications and technological demonstrations. Programme now framed in the NASA Earth Science Enterprise programme (ESE).
The platforms are actively stabilised over 3 axes.
The design life time is 6 years.
The satellites are on sunsynchronous orbits around 10:30 or 13:30, depending on the mission.
