Their holistic approach to space exploration certainly seems like the right direction as Kristian Pedersen, Director of DTU Space, stated “The LUNARK mission is an admirably ambitious project and a refreshing technology demonstrator of what the future Lunar Habitat might look like. This was and is an incredibly ambitious project so it follows that their success has earned them a number of awards and media headlines. Needless to say, a 3D printer will be an invaluable addition to space habitats. The Craftbot they brought with them was used multiple times to print tools, replacement parts, and even flexible patches to repair the walls of the habitat. In Northern Greenland, they survived hurricane winds, temperatures below -30☌, and polar bears, all in the comfort of the LUNARK. It includes some really fancy features, such as a weather simulator and a suite of software to monitor the algae reactor. Those printers helped the duo prototype functional scale models of the habitat with compliant PLA joints, and they later used the printers to manufacture 113 ABS joints for the full-size prototype that they field tested themselves for three months in the Arctic during the Fall of 2020! They dubbed their habitat LUNARK, a fitting name. When Craftbot got word of their selection, they were thrilled to help with the project, sending SAGA a fleet of eight Craftbot Plus and three Craftbot3 printers. The team ran a series of rigorous production tests on a number of major-brand 3D printers, finally selecting the Craftbot after it beat out the competition in speed, reliability, ease of use, and repeatability. They realized that they could leverage 3D printing in both the construction and the operation/maintenance of the habitat. This is where Karl-Johan’s love of 3D printing provided the missing puzzle piece. Since supply runs are incredibly limited and involve long time lags between a stated need and the actual delivery, it’s crucial that the inhabitants have some means of maintaining and repairing their own habitats. Knowing that you have some control over your nutrient supply is a huge relief when the only other source of nutrition is scheduled supply deliveries that are dependent upon regular, successful rocket launches that are also very expensive.įrom Prototyping to Manufacturing With 3D Printing And the garden goes a long way in reducing the tedium while simultaneously increasing the sustainability factor, a non-trivial consideration due to the extreme isolation. The foldable shape means inhabitants can have more than one room, making the space feel more like a home than a hotel even the small change of scenery that comes from moving between the sleeping area and the vertical garden area can help to mitigate some of the psychological stress of being confined in a small space. On top of all the other necessary living-space goods like furniture and electronics, they had to include space for the batteries (powered by exterior solar panels), an algae farm that powers the life support systems, and water. To combat claustrophobia, the overall structure makes use of origami folding techniques to maximize usable living space while minimizing shipping volume, which always comes at a premium. In space, your habitat is your entire world there is no nature or change of scenery,” said the duo.Īs such, they catered their design to accommodate as many of those human needs as possible. “If we are trying to settle on other planets, we must be very careful how we design the homes. Research indicates that the isolation of space is difficult to cope with for extended periods, especially when adding in a touch of claustrophobia and a dash of monotony that come with space exploration. Rather than recreate the sterile, scientific environment found on the International Space Station, their habitat factors in the limits of the human psyche, incorporating several features to enhance what the Danish call ‘hygge,’ or coziness. Those are the clients Karl-Johan and Sebastian were considering when designing their lunar habitat. As rocketry continues to advance, the cost of space travel will decrease, making it more feasible for non-astronauts to join in on the fun.
