JIUQUAN, Oct. 9 (China Space News) -- Two remote sensing satellites were successfully sent into space Tuesday from the Jiuquan Satellite Launch Center in northwest China.

The satellites, both part of the Yaogan-32 family, were launched by a Long March-2C rocket with an attached upper stage at 10:43 a.m. Beijing time.

The satellites have entered their planned orbits and will be used for electromagnetic environment surveys and other related technology tests.

This was the first flight of the upper stage named Yuanzheng-1S, or Expedition-1S. It cooperated well with the Long March-2C rocket and significantly improved the carrying capacity of the rocket.

The Yuanzheng-1S, a simplified version of the Yuanzheng-1, is designed for short flights, and will be mainly used for commercial launches.

Tuesday's launch was the 286th mission of the Long March rocket series.
