How is Ham, the monkey who was sent into space 50 years ago, doing now?

After returning to Earth, scientists conducted a physical examination on Ham and found that there was no abnormality in his body. But in the end it died after only living for 20 years, which was many years shorter than its peers. I believe everyone will feel very heartbroken when they see such a result.

As early as 50 years ago, humans had launched dogs and monkeys into space, but according to the theory of evolution, monkeys, which are also primates, seem to be more suitable for this important task. After people's careful training, a monkey named Ham was successfully sent to space, and returned to Earth safely after a certain period of time, becoming one of the few "survivors" in such experiments.

Before this, many animals have been sent to space, but many problems have to be overcome, such as the weightless environment and the maintenance of various instruments and equipment. A slight carelessness will cause a series of problems. In addition, it needs to pass through the atmosphere during launch and return, which is likely to cause serious damage to the animal's body.

This move by scientists is indeed to protect the safety of astronauts to the greatest extent, and at the same time, it is also laying the foundation for retaining a complete ecosystem after humans move into space. If this experiment can be carried out successfully, we are expected to send more animals and plants to space in the future, thus making the space station and space base more vibrant.

However, some people believe that these animals are relatively fragile and have many differences from humans, and many problems were not realized at the time. Recently, people have discovered that long-term space life will cause irreversible changes to the genes of astronauts. Similar problems will also occur in animals sent to space. Once space immigration is realized in the future, we have to pay attention to the impact of genes.

So the monkey Ham died 20 years ago.
