Human error may have been involved.

On Tuesday morning, a Russian Soyuz 2.1b rocket lifted off on schedule from a new spaceport, carrying the the Meteor M2-1 weather and climate satellite, as well as more than a dozen secondary payloads. However, the satellite never reached its target orbit, more than 825km above Earth.

According to Russian media reports, the Fregat upper stage separated from the rocket about 10 minutes after launch, but then something went wrong. At least one of the two firings of the Fregat stage, which is used to insert satellites into their designated orbits, apparently did not happen. Russian space journalist Anatoly Zak reports that human error may have been involved, with an errant pre-programmed flight sequence. Roscosmos has since lost contact with the satellite.

This failure is troublesome for the Russian space program for at least a couple of reasons. This is the fourth failure of the versatile Fregat space tug, which has been in service for about two decades. All of the problems have occurred since 2009, when there have been problems with flight data, third-stage failures, and control system failures. In each of the cases, the satellite did not reach its desired orbit.

Secondly, this was only the second launch from Russia's important new spaceport, the oft-delayed Vostochny Cosmodrome in far eastern Russia. The first launch of a Soyuz 2.1a rocket in April 2016, went off smoothly, but now more than a year and a half has passed since then. This was the first launch of the newer Soyuz 2.1b rocket and the first to use the Fregat upper stage.

Russia has a long, storied, and largely successful space program. But this latest failure is likely to only add to concerns in the global aerospace industry about deleterious effects on Russian spaceflight from low funding and mismanagement of the Russian space agency. As the country's heritage rockets and upper stages continue to age, the concern is that the failure rate will increase.
