Is Russia's rival to Starlink failing? Here's what we know.
At least three of the first 32 Rassvet satellites likely suffered outright failures, and more may be in trouble.
Russia’s attempt to replicate SpaceX’s Starlink satellite network seems to be moving as slowly as the front lines in eastern Ukraine.
The Rassvet program, often billed as Russia’s answer to Starlink, started launching its first operational satellites earlier this year. Two launches, one in March and a second in July, have delivered 32 Rassvet satellites to low-Earth orbit, some 10 percent of the roughly 300 Rassvet spacecraft Russia aims to put into orbit by the end of next year to provide connectivity for military and civilian users. The company in charge of Rassvet, Bureau 1440, wants to deploy 924 satellites by 2035.
But none of the 32 satellites launched so far have reached the 500-mile (800-kilometer) orbit they were designed to operate in. The rockets that launched the first two batches of Rassvets released the satellites much closer to Earth, and the satellites were expected to use their own plasma engines to raise their orbits over the next few months.
The highest altitude achieved by the Rassvet satellites so far is a little more than 300 miles (500 kilometers). Twelve of the 16 Rassvet satellites from the first launch in March have settled into orbits at this altitude, according to an assessment released Monday by the Institute for the Study of War. A chart published by Jonathan McDowell, an independent tracker of global launch and satellite activity, indicates one more Rassvet satellite may soon climb above 300 miles.
One Rassvet satellite from the March launch never made any significant maneuvers and reentered the atmosphere in June. The remaining two satellites have not raised their altitude in the last two months, an indication that they, too, may be experiencing problems.
Some satellites in the second batch of Rassvets also show signs of trouble. Two of them never maneuvered after launch in July and appear to be heading for reentry, according to Anatoly Zak, a journalist and editor of RussianSpaceWeb.com. Eleven of the 16 satellites launched in July were “noticeably climbing” by early August, Zak reported. Three more appeared to stop maneuvering after initial attempts to raise their orbits.
What are we to make of all this? What we can say for sure is that at least three of the first 32 Rassvet satellites likely suffered outright failures.
Some technical anomalies were expected. About 5 percent of SpaceX’s first batch of Starlinks failed almost immediately after launch. Over time, this group of 60 Starlink prototypes suffered a failure rate of about 13 percent, according to McDowell. With more experience, SpaceX’s next 420 Starlink satellites had a failure rate of about 3 percent. SpaceX’s current generation of Starlink Version 2 satellites has a failure rate of about 0.01 percent, according to McDowell’s tabulations.
The US military’s Space Development Agency is fielding its own constellation of data relay satellites for applications in missile targeting and command and control. Some of the agency’s first 42 operational satellites encountered thermal and propulsion problems after launching last year, and they have taken longer than anticipated to raise their orbits.
