Weight is without doubt one of the most crucial elements to area journey as it could actually have a major affect on the quantity of gasoline and thrust wanted to get a rocket out of the higher ambiance. But it isn’t even that straightforward as extra gasoline additionally provides to the general weight, and different issues similar to meals, substitute elements, objects which may be wanted for experimentation, and different provides must be budgeted for as effectively.

The expectation for 3D printers is that they might finally scale back the quantity of weight being taken up by objects like part elements and a few instruments. For instance, as a substitute of bringing a number of substitute elements in case one thing had been to wish fixing (which may lead to a number of objects that find yourself not getting used, however nonetheless take up a good bit of weight), batches of 3D printing supplies will be introduced alongside and used to print out precisely what’s wanted in a given scenario.

Additionally, one thing like a Refabricator might be introduced alongside to recycle unused, damaged, or changed 3D printed supplies to be used in future prints (per NASA). This would theoretically in the reduction of on the quantity of uncooked printing supplies wanted — thus chopping again on weight utilization as effectively — and has been in testing on the ISS since 2019. Once the printing and recycling expertise is refined, it may make long-distance area missions happening over years (as a substitute of weeks or months) rather more possible.
