Among other experiments, the spot landed on August 12 on the International Space Station. He is greeted by Thomas Pesquet who will study his behavior in space while French students will do the same on Earth.

This Tuesday, August 10, the Cygnus spacecraft took off from the United States for the International Space Station (ISS). Bring Renovation. Among them, the European Space Agency (ESA) experimental study Viscous liquid. During this project, I did In collaboration with the National Center for Space Studies (Cnes) and Audrey Dusseautour, researcher at the National Center for Scientific Research (CNRS), French student and Thomas Bisket He plans to conduct the same experiment on Earth and in space at the same time.
The point safely arrived at its destination on Thursday, August 12, at 12:07 (Paris time).

What experiments will be carried out at that point?
As part of this research, scientists young and old will first observe Point behavior and movement. It will be left in its empty crate where it will move in search of food.
In a second step, experimental representatives will see how dots work with four food sources. On Earth, he could connect them all using his venous system, but would he be able to do the same in the International Space Station’s laboratory?
The aim of this project is to educate students, from elementary school to high school and all levels, to science, but also to know what it is microgravity effect on this amazing creature.
But what’s the point?
Basically, his real name Vesarum polycephalusAnd This is a slime mold. This class of organisms can be confused with mold, but unlike the latter, it does not contain mold and does not feed absorbAnd But with phagocytosis. It is very easy to live with a unicellular organism: it can eat many things and it can grow in the laboratory No problem, it doubled in one day.
Shocking at first glance, but Vesarum polycephalus can move. It does this by contracting its venous system, thereby pushing its intracellular fluid against the cell membranemake it move.
NS Slime mold learning ability (who doesn’t have brain !) Equally unusual. Actually,noisy He doesn’t like certain chemicals like salt, but he can learn to tolerate them if you run into him a few times. This is what happened during the experiment on the Salt Bridge, which quickly crossed the “experienced” point, as opposed to the “naive” point. What’s even more impressive is that information can be transmitted between individuals if they touch each other.
In nature, it prefers cool and humid environments, such as forest basins or parts of it He drinks dead. In the event that it is not suitable for the surrounding conditions, the point can protect itself by adopting a file Ultra-resistant sleeping conditions For all bad weather. In this form he travels to the International Space Station.
