19 Satellites Launched from Vostochny Fail to Reach Target Orbit

Contact with 19 satellites, including Russia’s Earth observation Meteor-M 2.1, has been lost following a launch of a Soyuz rocket from Vostochny Cosmodrome, according to Roscosmos. The three-stage Soyuz-2.1b carrier rocket blasted off from the new spaceport in the Russian Far East at 8:41am Moscow time (5:41am GMT) on Tuesday. The rocket carried the Meteor-M 2.1 weather satellite and the secondary payload of 18 smaller satellites from other countries, including Canada, Norway, Japan and the US.

While the main satellite apparently reached intermediate orbit, contact with it was then lost. "During the first planned communication session with the satellite, it was not possible to establish a connection due to its absence in the target orbit," Russia's space corporation said in a statement, adding that further information is currently being analyzed.

The Fregat booster carrying a cluster of nineteen satellites may have been lost due to a failure in the GLONASS equipment, which is responsible for enhancing the accuracy of orbiting space satellites, a source in the space rocket industry told TASS.

"According to preliminary findings, there occurred a technical flaw in the booster’s satellite navigation equipment, which operates on the basis of GLONASS and GPS signals and enhances the Fregat’s accuracy in putting space satellites into the designated orbits," the source said.

Tuesday's mission was tasked with deploying Meteor and 18 smaller satellites from various countries, including Baumanets-2 (Russia), LEO Vantage (Canada), AISSat-3 (Norway), IDEA (Japan), SEAM (Sweden), two Landmapper-BC (the United States), 10 LEMUR satellites (the United States) and D-Star One (Germany).

The Russian Meteor satellite was aimed at monitoring the climate, controlling emergency situations and providing data for weather forecasts. The satellite can provide both global and local images of clouds, as well as data on ice and snow coverage conditions. Information received from the satellite could also have been used to monitor Earth's radiation balance.

Mixed messages circulated in the media on the fate of the satellites. They could have fallen into the ocean, Interfax news agency reported, citing sources. The same version has been voiced by RIA Novosti, quoting sources in the space industry, who added that whatever happened to the satellites, they may already be considered "space waste." The satellites could also have reached the wrong orbit.

The launch – the second ever from the new spaceport – happened more than a year after the first rocket, Soyuz-2.1a, took off from the Vostochny Cosmodrome in April 2016. Construction work at the site continues as additional launch pads are being built. The first manned mission to the International Space Station (ISS) to be launched from Vostochny is not scheduled before 2023.
