MOSCOW, January 24. /TASS/. The launch of a Meridian-M military satellite by a Soyuz-2.1a carrier rocket scheduled for January 24 from the Plesetsk spaceport in northern Russia has been delayed for 24 hours, a source in the space industry told TASS on Friday.

"The launch has been postponed for 24 hours," the source said.

The launch was expected to be the first lift-off of a space vehicle in Russia in 2020.

The launch of the Soyuz-2.1a carrier rocket with the Meridian satellite from the Plesetsk spaceport has been cancelled for three possible technical reasons, according to the source.

"Preliminarily, three possible reasons are being considered: a failure in the Fregat booster, a failure in the carrier rocket or a failure in the operation of the ground-based launch pad," the source informed. It specified that the command to cancel the launch scheduled for 2:00 p.m. Moscow time had been given back at around 09:00 a.m. Moscow time.

As per another source, the blast-off may be postponed indefinitely. "The launch may be delayed not until Saturday but for an indefinite period." 

The sources added that the command to cancel the launch had been given before the rocket’s fueling scheduled to begin at 10:00 a.m. Moscow time.

Commander of Russia’s Space Forces Colonel-General Alexander Golovko earlier reported that the Defense Ministry would launch another Meridian-M satellite in January 2020. The rocket was expected to blast off from the upgraded launch pad No. 3, he added.

The first launch from that launch pad took place on December 11, although it was initially scheduled for a day earlier.

Russia’s Reshetnev Information Satellite Systems Company received an order in 2017 for manufacturing four Meridian-M military satellites (the modernized version of Meridian space vehicles).

Reshetnev CEO Nikolai Testoyedov earlier told TASS that the company was planning to produce the first Meridian-M satellite at the end of 2018, the second — in 2019, the third — in 2020 and the fourth — in 2022. The time was chosen to ensure the planned replacement of existing Meridian satellites, he said.

The Meridians are second-generation communications satellites that replaced Molniya and Raduga space vehicles. The active service life of operational satellites is seven years.
