The “isolated” Emirati in Russia … a scientific achievement made by sacrifice

D + D – Normal size

Have any of us imagined living alone within four walls, without practicing his normal life for several days, without the sunlight touching the structure of its lines, or occasionally engaging those around him in conversations, then what to say? You were isolated for 8 months, during which time you did nothing but conduct scientific experiments in isolated situations. Emirati mission to simulate life in space as part of the “Sirius 21” project in an environment completely isolated from the outside world. It is carried out on the ground testing campus of the Medical and Biological Research Institute of the Russian Academy of Sciences. With the participation of 5 simulation pioneers from Moscow, USA and Russia.

The importance of conducting simulation experiments on Earth in situations such as space life, in search of in-depth insights into the conditions under which astronauts will be exposed and the preparation and collection of information that will be useful in future space exploration. To create similar scenarios for future trips into space, these missions may resemble the nature of actual missions, but their experiments include space technology used, human isolation, contact with the ground station and space experiments, as well as experiments. Understand the harsh conditions in space.

Space simulation missions are important experiments that draw the road map for exploring Mars and other planets and lay the foundations for designing and implementing future space missions.

Seal
Al-Amiri is currently conducting 71 experiments with his comrades from the US and Russian space agencies. It covers the fields of physiology, psychology and biology from 4 universities in the country. For the Moon, these stages include launching and orbiting, landing, and returning to Earth.

The team works on a sealed body that simulates a spacecraft, with the aim of assessing the impact of isolation on psychological and physical condition, mental and physical performance, as well as key physiological systems of the human body. The objectives of the test subjects include the creation of an integrated database of scientific data obtained during the implementation of the objectives project, according to environmental standards and isolated health conditions.

Life support
The test room chambers have autonomous life support systems controlled by an administrative system, creating a habitat that operates according to specific parameters, including ventilation system, air conditioning, air purification, gas analysis and support for certain conditions of temperature. , Humidity and gas mixing, as well as water supply, sanitation, electricity, electric lighting, video surveillance and fire extinguishing systems, home units of various sizes, and some other features such as day-night rotations. And innovative working conditions for research tailored to the demands of the examiners.

The campus has unique facilities for conducting general surveys of spacecraft for different periods of more than 500 days, while it is considered a simulation site with multifunctional testing units and can accommodate up to 3 to 10 people from the crew. The test is controlled and all systems are monitored by the team and the environmental standards from the project control center.

Sirius phases
The joint scientific research project, carried out in collaboration with NASA and the Russian Institute of Biological Research “Sirius”, simulates the conditions of long-term human spaceflight to study possible biological and psychological problems in humans. The project will last up to 5 years due to isolation in the limited space environment, as two phases of the project have been completed so far, the first phase included “Sirius 17”, and this was for a period of time. 17 days, from 7 to 24 November 2017.

The second stage, “Sirius 19”, lasted 120 days and took place between March 19 and July 17, 2019. The third stage, “Sirius 21”, will last 240 days starting November 4, and it will be isolated. The test simulates key aspects of future space exploration work, from which “Sirius 22/23” is scheduled for launch in 2022 and for a period of 12 months.

Food exports
Now, about 100 days after astronaut Saleh al-Amiri began his mission, he has completed a simulated experience of walking on the surface of the moon, using virtual reality devices, physiological sensors and smart suits fitted with astronaut costumes to witness in the days to come. Science is waiting for the results of new experiments to plan spacecraft that will carry humans into deeper space in the coming years.

Regarding the types of food eaten by astronauts during simulation missions, the director of the Emirates Space Simulation Project, Engineer Mohammed bin Nachok Al-Bayani, was told that 3 food cargoes would be sent to the mission staff. The space station where the astronauts are located, shortly before the first mission begins, when the astronauts arrive at the space station, they will find food that will help them spend their mission safely and its contents will be sufficient for the next 4. At -5 months, the second shipment will arrive two months later and the third shipment meal will arrive after the middle of the scheduled work period.

Dietary Supplements
He goes on to say that the quality of food ranges from canned foods to meat or fish, to legumes such as oats and other grains of high nutritional value, all of which add hot water to make it more palatable. They should be long lasting and contain vitamins and calories. The heat energy needed by the astronauts’ bodies during their spaceflight should be easy to store and should not take up much space inside the space station.

He points out that there is a serious pursuit by nutritionists to monitor the performance ratios of astronauts’ body systems and determine their needs, and therefore, plenty of nutritional supplements are shipped with food exports to meet physiological needs. Of body systems.
