Sultan Al Neyadi, the Emirati astronaut, reviewed the method of water formation at the International Station, through a video clip of one minute and 33 seconds, according to what he posted on Twitter.
And in the video clip, a small drop of water came out of a tube of a transparent package, then it soon grew in size in the form of a gelatinous bubble, until the astronaut touched it with his hand and wet a piece of cloth with it, in order to squeeze it, so that it remained gelatinous, as the water gathered around the towel. Like a sticky, oddly shaped piece of gel.
According to the explanation of the scientists for the formation of water in the International Station, as happened with the American pioneer Chris Hadfield, when he conducted the experiment at the end of 2012, their explanation is the presence of surface tension of the water, which acts as a very weak cover surrounding its outer wall, this surface makes it resistant (in a fragile and simple way). ) to external factors, in addition to the distribution of electric charges of water atoms, but its effect in space seems clear, unlike its effect on Earth, and the water atoms attract each other, and form what is called potential energy, which makes it appear coherent and gelatinous in space.--
According to the US space agency “NASA”, the International Station, with all its contents, is subject to a strong gravity equal to 90% of the gravity on the Earth’s surface, which makes the water in it behave as if it is in a zero-gravity environment.
In the same context, NASA announced that Al-Neyadi, who is on the longest mission of Arab pioneers aboard the International Station and lasts 6 months, is conducting experiments on a variety of research devices, which assist in search and discovery operations throughout the day, within the framework of the tasks assigned to him and his colleagues. other astronauts, estimated at 200 missions.
And “NASA” stated via “Twitter” that Al-Neyadi accomplished the tasks of preparing devices and computer “bimonitor programs”, as well as collecting medical data using a device placed on the head and a jacket loaded with sensors, in order to study the health of astronauts, to help scientists measure the impact of space flights in cardiovascular system.
