Without Russia, Science Going Solo on World's Woes, Dreams

Without Russian help, climate scientists worry how they’ll keep up their important work of documenting warming in the Arctic.

Europe’s space agency is wrestling with how its planned Mars rover might survive freezing nights on the Red Planet without its Russian heating unit.

And what of the world’s quest for carbon-free energy if 35 nations cooperating on an experimental fusion-power reactor in France can’t ship vital components from Russia?

In scientific fields with profound implications for mankind’s future and knowledge, Russian President Vladimir Putin’s war in Ukraine is causing a swift and broad decaying of relationships and projects that bound together Moscow and the West. Post-Cold War bridge-building through science is unraveling as Western nations seek to punish and isolate the Kremlin by drying up support for scientific programs involving Russia.

The costs of this decoupling, scientists say, could be high on both sides. Tackling climate change and other problems will be tougher without collaboration and time will be lost. Russian and Western scientists have become dependent on each other’s expertise as they have worked together on conundrums from unlocking the power of atoms to firing probes into space. Picking apart the dense web of relationships will be complicated.

The European Space Agency’s planned Mars rover with Russia is an example. Arrays of Russian sensors to sniff, scour and study the planet’s environment may have to be unbolted and replaced and a non-Russian launcher rocket found if the suspension of their collaboration becomes a lasting rupture. In that case, the launch, already scrubbed for this year, couldn’t happen before 2026.
