Here’s what I know about Sputnik 2. The pressurized, oxygenated cabin was just big enough for Laika—all 13 pounds of her—to sit, stand, or lie down; a harness and chains prevented her from turning around. A bag was attached to her backside to collect waste, and food and water were dispensed in gelatin form. At the time, the Soviets told the world that she’d lasted a full week before her oxygen ran out. In reality, she hadn’t survived longer than a few hours in orbit, heart palpitating with panic and baked by the blistering temperatures inside the cabin. Not that her handlers ever had a plan to bring her back; Laika’s trip was always meant to be one-way. Hours before the launch, mission scientist Vladimir Yazdovsky brought Laika to his house to play with his kids. 'I wanted to do something nice for her,' he wrote later. 'She had so little time left to live.'
From my unfinished short story “Satellites,” which includes lots of asides about Laika, the first dog in space, who was launched into orbit on this day in 1957.
