Haiyang 2E (Chinese: "Ocean"), abbreviated HY-2E, is a marine remote sensing satellite of China. The HY-2 series' primary objective is to measure ocean dynamic and regional environmental trends in the microwave spectral range, plus measurements of parameters such as marine wind vector, marine surface heat and Sea Surface Temperature (SST). These ocean dynamics real-time data aid aero-marine forecasts for the prevention of, and relief in the event of, natural disasters. Instruments carried include: * Microwave Radiometer Imager (MWRI) * Radar Altimeter (RA) * Ku-band Rotational Fan-beam Scatterometer (SCAT) July 1, 2026 at 23:46 UTC · Launch Successful Long March 4B — China Aerospace Science and Technology Corporation, to Sun-Synchronous Orbit Launch Area 94 (SLS-2 / 603), Jiuquan Satellite Launch Center, People's Republic of China The world's 7328th orbital launch attempt, and 155th of 2026.
