A group of construction engineering students at the American University in Cairo (AUC) explored potential building materials for Mars along with possible construction methods by making use of NASA’s 3D printed pre-existing model for their graduation project, on 23 February.

The team included Zenah Helmy, Gehad Ayman, Ziad Abdeen, Reem Gamal, Omar Sawan, and Kareem Reda.

The graduation project was supervised by Mohamed Naguib Abu-Zeid, professor of construction engineering, who encouraged the students to venture into this challenging topic.

“The topic is as interesting as it is challenging,” said Abdeen. “After all, how could you build on a planet no one has ever stepped foot on? Building on other planets sounds like something out of a movie. I have to admit that when the topic was introduced on the table, I had my doubts. However, fast forward a couple of months of research and work, now I firmly believe in it.”


Building in outer space is no longer an imagination. Instead, it’s a reality that is unfolding. Inhabiting Mars is indeed becoming a reality explored by NASA, especially after NASA’s Mars 2020 Perseverance rover succeeded in landing on the surface of Mars.

To start their project, the students gathered a lot of data and information on Mars, from the weather to the planet’s materials. “We encountered many challenges along the way, one of which is that we needed Martian regolith to use in our mixes, but of course, there isn’t any Martian soil on Earth, so we found a material with an extremely similar chemical composition and repurposed it to fit the Martian regolith composition.”

Through their research, the students made use of NASA’s 3D printed pre-existing model. NASA launched a 3D printed habitat competition from 2015 to 2019, calling out for building the most sustainable and efficient habitat on Mars using 3D printing technology.

For their project, the students located materials on Earth that exist on Mars and, hence, can construct the building on the planet itself with little to no need to transport any materials. They started with a doughnut icehouse designed to withstand intense radiation and massive daily temperature changes while providing a pressurised environment inside for humans to live in over a prolonged period of time. The membrane around the icehouse had to be transparent to allow light inside the building and prevent the feeling of isolation and confinement.

The students created Martian concrete, a new kind of concrete that doesn’t require water and is more than twice as strong, which they found had a similar chemical composition to the Martian regolith.

“This research shows how our students think creatively and keep up with the cutting edge of technology,” said Mohamed Naguib Abu Zeid, professor of construction engineering and thesis supervisor.

“They have tackled that challenge by exploring materials, techniques, and means to build on planet Mars. Thinking totally out of the box and dealing with severe and different climatic and physical conditions, they managed to pinpoint several options for such buildings, utilising materials on Mars by simulating Earth’s existing ones. Another great outcome of this project is to be able to handle complex challenges on planet Earth itself.”

“SpaceX is currently testing its new spacecraft called Starship, which will be the vessel that carries both people and cargo to the Red Planet,” said Ayman. “The company estimates that the first humans to land on Mars will get there by 2024. The company’s CEO, Elon Musk, thinks that there will be a functional colony on Mars in the next 100 years.”

“Our research is just the beginning, and many more in the scientific community will definitely pick up this topic as NASA and SpaceX get closer to making it a reality and making us an interplanetary species,” said Helmy, on behalf of the team, “This is coming, so we need to prepare and be ready for this reality because if it is not us, then who? And if not now, then when?”
