And Soyuz Makes Six….

The failure of a Russian Soyuz booster to orbit a weather satellite and 18 CubeSats on Tuesday was the sixth launch mishap of the year. That total includes five total failures and one partial failure out of 79 orbital launches.

On Jan. 14, the maiden launch of Japan’s SS-520 microsat booster failed after takeoff from the Uchinoura Space Centre. JAXA said controllers aborted second-stage ignition after losing telemetry from the rocket. The booster was carrying the TRICOM-1 nanosat.

A second launch has been scheduled for Dec. 25. The SS-520 is an upgraded version of a Japanese sounding rocket.

The maiden flight of Rocket Lab’s Electron booster failed after launch from New Zealand on May 25. Company officials said controllers terminated the flight after faulty ground equipment lost telemetry from the booster, which was functionally nominally. Rocket Lab is gearing up for a second launch attempt that could occur in December.

China’s Long March 3B suffered a partial failure on June 19 after launch from Xichang. An under performing third stage left the ChinaSat 9A communications satellite in a lower-than-planned orbit. The spacecraft reached its proper orbit using on board propulsion, with a reduction of its orbital lifetime.

On July 2, a Chinese Long March 5 booster failed after liftoff from the Wenchang Satellite Launch Center.  The rocket was carrying an experimental geostationary satellite named Shijian 18. It was the second launch and first failure for China’s largest booster. Officials have no announced the cause of the failure.

India’s PSLV rocket suffered a rare failure when the payload shroud failed to separate during a launch on Aug. 31. The IRNSS-1H regional navigation satellite was lost. The booster is set to return to service on Dec. 30.
