摘要

The Jan. 31 failure of a Sea Launch rocket carrying Intelsat's IS-27 satellite, in addition to being a huge setback for a company struggling to regain its footing following bankruptcy proceedings, suggests that commercial satellite operators are in a precarious position when it comes to getting their assets into orbit. The failure came closely on the heels of another upper-stage glitch involving one of the commercial market's two main workhorses, the Proton rocket, reinforcing concerns about quality control in the Russian-led space industrial complex upon which the satellite communications industry relies heavily today. The December malfunction, which left a Russian communications satellite in a low orbit was the third in 16 months involving Proton's upper stage - two others, in August 2011 and August 2012, resulted in the loss of three telecom satellites.
