November 3, 1957: The dog named Laika became the first animal to go into space. It was sent by the Soviet Union. Laika was killed during this mission.
September 3, 2022: Now, after 65 years, the American space agency NASA is sending 3 high-tech mannequins, that is, two female and one male effigies to the moon mission.
In this explainer, we learn why NASA goes to space dummies instead of humans, why they are special, and what information NASA wants to collect through them.
Why does NASA send mannequins to the moon?
The danger of radiation in space is very high. In most cases, cancer also occurs. That’s why America, which is preparing to send humans back to the moon, is sending mannequins instead of humans on its Artemis-1 mission. These dummies are called dummies and these special dummies are used for scientific research.
Their names are Helga, Johar and Moonikin Campos. Collectively these are called ghosts. These mannequins have been manufactured by the DLR Aerospace Center in Germany. At the same time, the name of the third effigy is Moonikin Campos, whose body is like that of a man.
These NASA effigies are like humans. They are made of plastic like the tissue of the human body. They will also have bones, skin and lungs like humans.
Mannequins such as Helga and Johor are also used to check the correct dose of radiation in cancer treatment.
Helga and Johar are effigies like women’s bodies. They are sent to examine the effect of radiation on women’s bodies in space.
The third effigy is being sent to Moonikin Campos to test how difficult it will be for humans to go to the Moon in the near future. This is one of the scientific experiments to increase understanding about space.
Moonikin will remain in the Campos rocket commander’s seat.
Thousands of sensors will record the effect of the radiation
Sensors have been installed in those parts of the mannequins’ bodies, where the effect of radiation is higher on the human body. From launch to return to Earth, thousands of its sensors will record the possible effects of radiation on the human body in space.
Sensors have been installed to see the effect of radiation on parts such as the lungs, stomach, uterus and bone marrow.
Dress code for Helga and Johar
Johar will wear a radiation protection jacket. This jacket is called AstroRed. The other Helga effigy will ship without a jacket. This special jacket is made of polyethylene terephthalate, which will protect Johar from harmful protons. This will cover your upper body and uterus.
Through this mission, the radiation falling on Helga and Johor will be compared. With this, scientists will discover how better protection can be offered to humans going into space in the future.
In the picture you can see that Johar is wearing a radiation protection jacket. While Helga is next to him he is not wearing a jacket. It has been made by a new company of the Israeli Space Agency.
Why the emphasis on sending lady mannequins into space
It raises the question of why NASA sends only female effigies into space. Thomas Berger, chief scientist of the Matroschka AstroRad Radiation Experiment (MARE) at Germany’s DLR Aerospace Center, which made these effigies, says: “The number of female astronauts is increasing, so we made effigies of women. One of the reasons for this is that, in general, women’s bodies are more affected by radiation.
In fact, according to NASA’s test, women’s bodies are not able to withstand the radiation required for space.
30% of engineers on NASA’s Artemis-1 mission are women.
Fruit flies went to space for the first time
Fruit flies were sent into space on February 20, 1947. This was the first time a living thing went into space. After that, many animals such as rats, monkeys, cats, frogs and dogs were sent into space.
The first dog that went into space – Laika.
Man stepped on the moon for the first time in 1969
In July 1969, NASA sent a human to the Moon for the first time. On July 21, 1969, American astronaut Neil Armstrong became the first human to walk on the moon.
NASA’s Artemis-1 mission in an attempt to send humans to the Moon
Now, after 53 years, NASA will once again send its ‘Orion’ spacecraft to the moon on September 3 as part of efforts to send humans to the moon. NASA has named this mission Artemis-1. It will not land on the surface of the moon but will circle it.
After that, NASA plans to send Artemis-2 in 2024. In this, astronauts will return to lunar orbit without setting foot on the moon. NASA’s Artemis-3 moon mission is expected to launch in 2025, in which astronauts will land on the lunar surface.
Artemis-1 will orbit the Moon for 42 days in space.
Snoopy Dog, the dog that went to the moon during NASA’s Apollo 11 mission, became very famous. It reflected the thinking of the American people about the success of the Apollo mission. This cartoon character was created by Charles M. Schultz in his comedy series ‘Peanuts’. The pen nib with which he made this series will also travel into space with Artemis-1.
The tip of Snoopy Dogg, the character of the children’s magazine ‘Peanuts’, also goes to the moon with Artemis-1.
Along with this, the 4 favorite leagues of children will also take this trip to the moon. NASA and the LEGO Group have been working together for the past 2 years to teach young children about space.
NASA and the LEGO Group are holding ‘Build to Launch’ online classes to teach kids about Artemis-1.
The souvenir from the Apollo 11 mission and the small piece of engine will also go to the Moon
Memorabilia from NASA’s Apollo 11 mission, small rocks brought from the surface of the moon and a small piece of the rocket engine from that mission also go on the trip to the moon with Artemis-1.
This little nut from the Apollo 11 mission rocket will also go to the Moon with Artemis-1.
Apart from these, the seeds of different trees also go to the moon in Artemis-1. NASA sent similar seeds with the Apollo 14 mission. These were brought back and planted under the name “Moon Tree”. This is done to see the effect of space radiation on the trees. Also going to this mission will be flags, pins and patches from all the countries participating in this mission. They will be brought back and distributed among these countries.
