Sixth geosynchronous satellite of the Space Based Infrared System program (SBIRS), providing capabilities for early missile warning and missile defense. SBIRS GEO-6 is the second satellite using Lockheed Martin's LM2100 combat bus.
Geostationary Transfer OrbitNote: Launch vehicle and payload uncertain. The Terrestrial Ecosystem Carbon Monitoring Satellite (TECIS) is intended to evaluate forest biomass, measure atmospheric aerosol content, and detect photosynthetic fluorescence. These measurements will contribute to efforts to combat global warming. The satellite carries 4 instruments: Multi-Beam LIDAR, Directional Multi-Spectral Camera, Directional Polarization Camera, and Chlorophyll Fluorescence Hyper-Spectral Monitor (SIFIS) The satellite will operate in a sun-synchronous orbit at a height of 506 km, at 10:30 AM local time in the descending mode, with a designed lifetime of 8 years.
Sun-Synchronous OrbitWentian is the first Laboratory Cabin Module (LCM) and second major component of the Chinese spacestation. It will provide additional navigation avionics, propulsion and orientation control as backup functions for the Core Cabin Module (CCM) as well as a pressurized environment for researchers to conduct science experiments in zero gravity.
