NASA’s Artemis I mission: These are the three dummies that will go on board to orbit the Moon


With the date allocation for the launch of the Artemis I Mission of the POT, it’s time to meet the three mannequins that will go aboard the Orion ship. Are Helga, Zohar and Moonikin Campos.

Why are mannequins traveling instead of human beings in this first part of the Artemis Program? To know the effects of radiation. They will all have sensors and other measurement elements.

The Orion spacecraft and NASA’s Space Launch System (SLS) mega rocket they will fly next August or September, spending more than 40 days in space. Its destiny is to orbit the Moon and then splash down on Earth.

Specifically, the dates provided by the North American aerospace agency are August 29, September 2 and September 5. Learn more about the itinerary of the Artemis I Mission in this link.

The Artemis I Mission will be followed by a second mission that will follow the same route, but this time with astronauts. In the third, the first woman and the next man will arrive on the Moon.

Helga and Zohar, the female mannequins for the journey of Artemis I

Helga and Zohar are two identical “ghost” torsos who will occupy the lower seats in Orion. Part of the scientific study called the Matroshka AstroRad Radiation Experiment (MARE), they are designed to measure the amount of space radiation astronauts might experience.

These mannequins were created by DLR Institute for Aerospace Medicine in Cologne, Germany, and they have bones and soft tissues, as well as sensors in areas such as the chest, stomach, uterus and bone marrow.

They have more than 10 thousand sensors that They will explain what the effects of radiation are on the woman who travels to the Moon.

According to Thomas Berger, head of the Biophysics working group in the Department of Radiation Biology at the DLR Institute, the radiation to which the human body is exposed is greatest outside of the Earth’s protective magnetic field.

the female body it is much more sensitive to this radiation in organs such as the breasts.

Both Helga and Zohar are 95 centimeters tall, weighing 36 kilograms. While Helga will travel without protection, Zohar will have a radiation protection vest.

Moonikin Campos and his history at NASA

The only one of the mannequins that will be “complete”, with head, arms and legs, is Moonikin Campos. Moonikin is a play on words with Luna and Mannequin in English, while Campos was the last name of Arturo Campos, the Hispanic engineer who helped save the astronauts of Apollo 13.

Remember the expression “OK Houston, we have a problem”? That problem, in NASA’s third attempt to put people on the Moon, was an explosion on the spacecraft, which affected astronauts John Swigert (the one with the famous phrase), Jim Lovell and Fred Haise.

The electrical engineer Campos (1934-2001), born in Laredo and of Mexican descent, helped the astronauts to survive the accident.

Like Helga and Zohar, Moonikin Campos uses sensors to provide data on what the crew of Artemis I might experience.

It has, according to the aerospace agency, two radiation sensors and the first generation of the Orion Crew Survival System, in addition to the spacesuit that astronauts will wear during launch, entry and other phases of the missions.

His seat has two sensors, one under the headrest and one under the seat, to record acceleration and vibrations during the mission.

According to Jason Hutt, head of Systems Integration for the Orion Crew, “it is crucial that we get the data from the Artemis I dummy. to ensure that all the newly designed systems, coupled to the energy damping system on which the seats are mounted, are integrated.”
