China will launch the Terrestrial Ecosystem Carbon Inventory Satellite aboard a Long March 4B.


Terrestrial Ecosystem Carbon Inventory Satellite

The Terrestrial Ecosystem Carbon Monitoring Satellite (TECIS) aims 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 synchronous solar orbit at an altitude of 506 km, at 10:30 local time in descending mode, with an expected duration of 8 years.


Long March 4B

The Long March 4B is a 3-stage, medium-range, liquid-fueled rocket in service since 1999. It uses hypergolic fuels in all three stages. Long March 4B is an expendable launch vehicle, which means none of the stages are recovered.


The first stage The first stage of the Long March 4B is 27.91m long, with a diameter of 3.35m. It uses asymmetric dimethylhydrazine (UDMH) for fuel and nitrogen tetroxide (N 2 0 4) for an oxidizer. It has four engines designated YF-21C. The stadium as a whole has a thrust of around 2,960 kN.


The second stage The second stage has a length of 10.9 m and a diameter of 3.35 m. The stage uses a single YF-24C engine. The thrust of the second stage is 742 kN


The third stage The third stage is 4.79m high and has a diameter of 2.9m. Use UDMH and N 2 O 4 as for the previous two stages. It has a pair of YF-40s. Each of these engines provides 103 kN of thrust.


No launch livestreams will be available.
