European space partnerships with Russia face uncertain future amid Ukraine tension

Astronauts regularly tout how living aboard the International Space Station tears down barriers. Right now, two Russian cosmonauts and one European astronaut are living in orbit together with four Americans. The seven spaceflyers are enjoying the fruit of international cooperation that dates back to the historic 1975 Cold-War era docking between the U.S. Apollo and Russian Soyuz spacecraft.

But back on Earth, fears over a major conflict in Europe are rising as more and more Russian troops assemble on Ukraine’s border, threatening a full-scale invasion of a sovereign country. The United Nations’ Secretary General António Guterres described the developments as “the most serious global peace and security crisis in recent years.”
