With NOM4D program, DARPA pursues the construction of large structures in space

In the future, humans will set foot on the moon again and even travel to Mars one day. In this regard, DARPA recently launched a new program called “Construction, materials and new optimal design of the moon and orbit” or “NOM4D” Unveiled Which seeks to develop new technologies for the construction of large-scale compatible structures in space.

The aerospace industry has made great strides in recent years, and with reusable rockets, humans can perform space missions more than ever before. While these advances have led to the development of sophisticated nanosatellites, humans still need large spacecraft and structures.

However, large rockets are needed to transport them into space, which can lead to heavy casualties. If man is to build a large structure such as the 420-ton International Space Station, he must send its modules into space separately and create such a structure. However, such a method also has its own problems.

Now, with NOM4D, DARPA wants to take a different approach, not only assembling such modules in space, but also building them in space. The main idea is to transfer advanced materials into space and then build large structures in space.

In this way, larger solar antennas and arrays can be created than in the past, and they will also weigh less. Despite their lower weight, their strength and compatibility will be higher.

The program was created with the idea that the space will be advanced in terms of logistics and facilities by 2030, and we will also regularly see orbital launches, as well as flying to the moon and orbital refueling. In addition, we create robots to build structures in space, robots that can instantly monitor and evaluate operations.

Participants in the NOM4D program must go through a three-step process, each lasting 18 months, focusing on a specific concept. The first step involves achieving the desired structural efficiency for a 1 MW solar array.

The second phase focuses on risk reduction and technical development for a 100-meter radio frequency reflector. The final step will be to show enough precision to build an infrared reflecting structure for an infrared telescope. All of these steps must meet the technical requirements.
