Scientists choose which animals will live on Mars first

As humanity advances in space exploration and considers the possibility of colonizing other planets, such as Marscomplex challenges arise.

This includes, for example, the selection of the most suitable animals to inhabit these extraterrestrial environments.

This question becomes increasingly relevant as NASA and other space agencies step up their efforts to establish permanent lunar bases and plan crewed missions to Mars.

The history of space exploration dates back more than sixty years, when the dog Laika became the first animal to orbit the Earth, paving the way for a series of scientific and scientific discoveries. technological advancements.

Today, with the prospect of colonizing Mars on the horizon, scientists face unprecedented challenges, and among them is choosing which animals can survive and thrive in Martian environments.

The adaptation of animals to reduced gravity is one of the main considerations.

With the gravity on Mars about a third of that found on Earth and, on the Moon, approximately a sixth, the effects on the muscular and bone development of animals are uncertain.

In this context, researchers and experts consider smaller animals, such as rodents, and aquatic life forms, such as fish, to be more viable options for colonizing Mars.

Despite this, fish emerge as ideal candidates due to their capacity for sustainable development through buoyancy and feed efficiency.

Here, it is interesting to remember that, in a simplified way, human beings evolved from water. This is because there was a transition from aquatic life to terrestrial life.

This process was complex and involved many years, evolutions and adaptations.

Possibilities don’t stop there

Furthermore, insectsespecially crickets, are also considered viable options, offering an affordable, rich source of protein.

Additionally, they take up less space and consume less water than traditional protein sources.

However, the challenges of establishing an extraterrestrial colony go beyond choosing animals.

Scientists are working to understand how to create ecosystems sustainable in challenging environments, like Mars, and ensure future colonists have the resources they need to survive and thrive.
