March 17, 2022, was a rough day for Jorge Vago. A planetary physicist, Vago heads science for part of the European Space Agency’s ExoMars program. His team was mere months from launching Europe’s first Mars rover — a goal they had been working toward for nearly two decades. But on that day, ESA suspended ties with Russia’s space agency over the invasion of Ukraine. The launch had been planned for Kazakhstan’s Baikonur Cosmodrome, which is leased to Russia.
