Summary
The OCO 2 (OCO-2) satellite, designated by NORAD CAT ID 40059 and OBJECT ID 2014-035A, is a LEOStar-2 configuration satellite built in the United States by OSCD for Earth Science missions. Launched on July 2, 2014, from AFWTR SLC2W using a Delta 7320-10C launch vehicle, it operates under the ownership of GSFC with an orbital lifetime of two years. The satellite measures 2.1 meters in length and has a diameter of 0.94 meters, spanning 9 meters when fully deployed. It carries three grating spectrometers as its primary equipment for conducting Earth science observations, specifically focusing on carbon dioxide measurements through its Orbiting Carbon Observatory payload. OCO 2 is powered by two deployable solar arrays and batteries. Its dry mass is 409 kg with a launch mass of 454 kg, and it features an AOCS motor system for attitude control. The satellite's shape consists of a hexagonal cylindrical body plus two panels.
