Ham was trained to work with operant conditioning, using a system that would send electric shocks to his feet when he made a mistake and reward him with a banana pellet if he did well.
During the flight, this system went haywire and sent electric shocks even though he was doing a great job at fullfilling his tasks. He was also exposed to almost 15 g’s of acceleration rather than the predicted 11g. Finally, the cabin lost pressure during flight, and reentry damaged the bottom of the craft which started taking in water after landing.
After his historical flight, Ham clearly wanted nothing to do with space anymore and started showing symptoms similar to PTSD. He was thus allowed to retire.
Laika (c. 1954 – November 3, 1957) was a Soviet space dog who became one of the first animals in space, and the first animal to orbit the Earth.
Laika was a stray dog, originally named Kudryavka (Russian: Кудрявка Little Curly); she underwent training with two other dogs, and was eventually chosen as the occupant of the Soviet spacecraft Sputnik 2 that was launched into outer space on November 3, 1957, (becoming the first dog in space, to orbit the Earth, and was also the first animal to die in space.) The Soviets designed the spacecraft knowing she would not survive. One Soviet scientist took her home to play with his children because he said “I wanted to do something nice for her. She had so little time left to live.” Laika likely died within hours after launch from overheating, possibly caused by a failure of the central R-7 sustainer to separate from the payload. The true cause and time of her death was not made public until 2002; instead, it was widely reported that she died when her oxygen ran out on day six, or as Soviet government initially claimed, she was euthanized prior to oxygen depletion.
As a kid who was very into rockets and airplanes I remember being told about her (mind you, I wasn’t born until the cold war was ending), but in my childish innocence I assumed she came back okay.
Here’s a statement made by Oleg Gazenko, one of the Sputnik scientists:
“Work with animals is a source of suffering to all of us. We treat them like babies who cannot speak. The more time passes, the more I’m sorry about it. We shouldn’t have done it… We did not learn enough from this mission to justify the death of the dog.”
You know what makes me (sorta) happy? They built her a window. Despite the challenges and costs of building a secure window in a pressurized capsule, they did it so the dying dog could look out.
Gazenko speaks of the bond that grew between the dog and him as they worked toward her mission, leading us in unembroidered prose through a brief tale of preparation, hours of readiness on the launch pad, and the launch itself. But the heart of the article for me, and the part to which nothing I’ve found since makes reference, is this: Gazenko tells us that as engineers rushed against deadlines to complete the capsule that would carry the dog into space, outfitting it with equipment to record the details of her death, he took on a battle in Laika’s behalf. Against heavy objections from the decision-makers, he insisted upon the installation of a window. A window in a space capsule, where such a luxury would cause complications and expenses that I can barely imagine. A window for the dog whose monitored demise had been this man’s objective in all the interactions that had bonded her to him with the eager devotion of every well-trained working canine.
Yet Gazenko persisted and prevailed.
Roof In Peace.
