Summary
Zhangheng-1 (CSES) launched on a China Aerospace Science and Technology Corporation Long March 2D from Launch Area 94 (SLS-2 / 603), Jiuquan Satellite Launch Center, People's Republic of China on February 2, 2018 at 07:51 UTC. The launch window ran from 07:43 to 08:12 UTC. It was China Aerospace Science and Technology Corporation's 213th launch, 6th this year and humanity's 5,721st orbital launch attempt. It was the 38th Long March 2D flight and the 3rd this year. The payload was bound for Sun-Synchronous Orbit (SSO). FengMaNiu 1, one of 11 catalogued objects, reached a 496 × 516 km orbit inclined 97.3°. 11 objects from this launch are catalogued, 7 of them payloads.

About this launch
Zhangheng-1, also known as CSES (China Seismo-Electromagnetic Satellite) is a scientific mission dedicated to studying the ionospheric precursors of earthquakes. Data collected by the mission will also allow studying solar-terrestrial interactions and phenomena of solar physics. This mission is a collaboration between China National Space Administration and the Italian Space Agency. CSES satellite weighs about 730 kg and it is to reside in a 98° sun-synchronous circular orbit at an altitude about 500 km, where it is expected to operate for 5 years.
