Resistance against the Russian war in Ukraine comes in many forms, such as just remaining at work and refusing to leave. In this episode, Laura Winter speaks with two former heads of the State Space Agency of Ukraine, Volodymyr Usov and Lyubomyr Sabadosh, and their colleague Liliya Shevchuk, the director of the country’s Space Initiatives Center. But first, Winter speaks with Homer Hickam, a retired NASA aerospace engineer and a New York Times best-selling book author, who wrote a Washington Post opinion piece, published on March 9, with the headline “Our space partnership with Russia can’t go on.”
