This month, two years ago, Russia’s unprovoked invasion of Ukraine started with a cyber attack that changed everything and yet nothing for the U.S. commercial space sector. This is the fourth and final in a series of episodes examining cyber attacks and space systems. Laura Winter speaks with Samuel Visner, Space Information Sharing and Analysis Center (Space-ISAC) Board Chair and Fellow at The Aerospace Corporation; Namrata Goswami, an independent scholar on space policy and great power politics and co-author of the book “Scramble for the Skies”; and Sean Costigan, the lead for NATO’s cybersecurity curriculum, and Director of Cyber Policy at Red Sift.
