Russian scientists have again delayed the launch of a research spacecraft to the sun over technical issues, researchers say.
A Russian Academy of Sciences official told state-run media on Tuesday that work on “Interheliozond” had been suspended in favor of “projects that are ready to launch as well as international cooperation.”
“There were issues related to some excess mass,” Vladimir Kuznetsov, the head of the Institute for Terrestrial Magnetism, Ionosphere and Radio Wave Propagation (IZMIRAN), told the state-run TASS news agency.
“The conceptual design had to be refined [...] We’ve stopped at this point for now,” Kuznetsov was cited as saying.
Interheliozond is still due to launch from Baikonur in 2026, he said.
