"The launch of Soyuz-2.1b was carried out as planned — at 21.55 Moscow time [18:55 GMT]. The separation of the satellite is expected at 22.05 Moscow time [19:05 GMT]," the official said.
The Resurs-P satellite, which has a 5-year service life, carries an imaging payload consisting of high-resolution, hyper-spectral and area survey instruments.
Another Resurs-P satellite's construction began in May 2012, and the launch is expected in the end of 2015.
The Resurs-P satellites, where P stands for prospective, are a modernized version of the Resurs-F1 satellites, which saw their first launches in 1979. The Resurs-F1s were constructed based on the Zenit spy satellite.
