He Baikonur Cosmodrome, in Kazakhstanhe has witnessed the launch of the Soyuz-2.1b rocket that has put the mission into orbit Bion-M No. 2. This Russian space agency project, Roscosmos, is a crucial step in the investigation of the effects of the microgravityand above all, the Cosmic radiationabout living organisms. But on board they are not human, but travel flies or mice, among other organisms.
A varied crew on the ship. As if it were Noah’s ark, 75 mice are found in this ship, more than 1,000 fruit fliescellular crops, microorganisms and plant seeds. For a month, these ‘bionautas’ will orbit the earth in a polo pole trajectory, at an altitude that will expose them to the levels of cosmic radiation significantly higher than those experienced in the International Space Station.
A “high -tech mice hotel”. The true protagonists of this mission are the 75 mice, who will travel in a specially designed passenger cabin: a “mini hotel”. Each unit is equipped with food, lighting, ventilation and waste systems to guarantee their well -being during the trip. In addition, chips have been implemented in some of the rodents to be able to monitor the constants in real time.
Scientists have divided mice into three groups to compare the results. The first will remain on earth in normal conditions, which is what we call in science ‘control group’. The second will live in a land laboratory in flight equipment identical to those of the satellite. The third group, of course, will be the one who travels to space. In this way, the effects of the space flight of other variables can be isolated.
Why are they chosen to mice. It has already become an iconic image to see how in biomedical research Mouse is used as the ideal test ‘subject’. And it is not a coincidence. The mouse has a genetic very similar to human, they have a short life cycle to see changes throughout several generations and are very economical to maintain and feed.
On the other hand, for this specific investigation the mice They are very radiation sensitiveso they make it the ideal subjects to give us more information on the effect of this physical phenomenon.
It has important implications for our health. The objective of this mission is clear: knowing how this radiation will affect astronauts traveling to the moon or Mars. Cosmic radiation In the long term you can damage cell DNAdrastically increasing the risks of long -term cancer, and what you want is to quantify the real damage and prove countermedons as armor for ships and drugs that avoid these undesirable effects.
But it also has medical applications here on Earth. Its results can give us more weapons to fight aging, since the rapid loss of bone and muscle mass suffered by astronauts is a perfect model to study osteoporosis and sarcopenia to find new treatments.
There are more research apart from mice. In collaboration with the Vernadsky Institute of Geochemistry and Analytical Chemistry, the mission transports 16 test tubes with dust simulations and lunar rocks. The objective is to study how radiation and space emptiness affect these materials, information of great value for the future development of lunar bases.
Other experiments on board will investigate the susceptibility of organisms to radiation, the development of new life support systems and possible medical benefits in the earth derived from spatial biological research.
Continuing the legacy of the bion-m No. 1. This mission It was launched in 2013 And he also spent 30 days in the orbit. However, the new mission will orbitate a 97 degree inclination, which will increase exposure to cosmic radiation compared to its predecessor.
It is not the first time that it is investigated in space. There are many precedents that exist of space missions that have aimed at investigation. For example, I know analyzed the potential risks of fertility in space in mice or even the Japanese wanted to see If you can procreate in space through mouse embryos.
