After almost fifty years of human stay in space, much information has been obtained about the effect of its microorganisms on humans and other living organisms; But the effect of space on some things, such as fire, planar worms, or even plants, is not always completely certain, and only experiments can provide a definitive answer. Here are some of the strangest experiments humans have ever done in space.

‍1. Floating space costume


The video below simulates a nightmare. The empty Russian space suit is released into the vacuum without any connection from the International Space Station (ISS). Based on the idea of ​​this experiment, old space costumes can be used as satellites. The SuitSat 1 test was launched on February 3, 2006. There are conflicting reports about this experiment. According to NASA, the radio connection was lost shortly after the space suit was dropped, but according to Russia, the connection was cut off two weeks later. The last signal was received on February 18. SuitSat 1 was in orbit for several months and burned to the ground on September 7, 2006.

2. Hammer and feather test


In the late 16th century, Galileo overthrew Galileo from the Leaning Tower of Pisa in Italy. Both spheres landed at the same time; With this experiment, he proved that mass has no effect on gravitational acceleration. All objects fall at the same speed, regardless of mass, even if the two objects being compared are full and hammered.

Galileo is difficult to perform on the ground due to air resistance; But nearly 400 years later, humans repeated the experiment by landing on the moon. On August 2, 1971, Apollo Governor David Scott performed 15 Galileo experiments with a hammer and feathers. He lifted two objects to a height of approximately 1.6 meters and then dropped them. Since the astronaut was completely in a vacuum and there was no air resistance, two objects fell to the ground at the same time. The hammer and fill of this experiment are still on the moon.

3.Boiling tablets in a water bubble

Under microgravity conditions, if you release some water from the nozzle, it will be suspended in the bubble and vibrate in space. Numerous experiments have been performed on water bubbles in space: experiments on water bubbles in a vacuum aircraft and the International Space Station, connecting water bubbles to large bubbles inside the speaker to observe sound oscillations, and placing the GoPro camera in the water bubble and filming from inside.

In 2015, Scott Kelly painted water bubbles with food coloring, then inserted effervescent tablets into the bubble to study the release of gas into the bubble. The experiment was filmed using the space station’s new 4K camera.

4.Fire in space


Fire, like water, behaves strangely. The Mir space station caught fire in 1997, and fortunately it has not been repeated, but examining the behavior of fire in its microscopes can help secure long-term missions such as manned missions to Mars and the construction of permanent space bases on the moon. These tests can also be used to improve security protocols on the ground.

To achieve the above goals, several research projects were devoted to the study of flame behavior in space. Experiments involving the combustion and decay of solids on the International Space Station have been devoted to investigating the properties of fuel and the destruction of a wide range of fuels in its microgravity. The data from these experiments can be used to build more complex models and understand the details of combustion in gravity. For example, scientists outside the Signus cargo spacecraft studied the behavior of flames under different conditions. NASA flame design research is also dedicated to the study of smoke production and control.
