China successfully launched the Haiyang 2E (Ocean) marine remote sensing satellite on July 1, 2026, from the Jiuquan Satellite Launch Center. The HY-2E mission is designed to monitor ocean dynamics and environmental trends through microwave spectral measurements. The satellite will collect critical data on marine wind vectors, sea surface temperature, and ocean surface heat characteristics, providing real-time information essential for aeromarine forecasting and natural disaster prevention and relief operations.

The Long March 4B launch vehicle, operated by China Aerospace Science and Technology Corporation, lifted off at 11:38 p.m. UTC from Launch Area 94 at Jiuquan. The Long March 4B is a reliable workhorse for China's space program, widely used for deploying Earth observation and remote sensing satellites to polar and sun-synchronous orbits.

The mission achieved a successful launch outcome. Haiyang 2E carries three primary instruments: the Microwave Radiometer Imager for thermal measurements, a Radar Altimeter for ocean surface profiling, and a Ku-band Rotational Fan-beam Scatterometer for wind vector analysis. As part of China's ongoing Haiyang series, this satellite continues the nation's commitment to ocean monitoring and environmental observation capabilities.
