Getting again to the Moon is the first objective of NASA’s Artemis program, however what will we do as soon as we get there? That’s the problem tackled by a bunch of scholars on the College of Illinois Urbana-Champaign, who wrote a proposal for a lunar infrastructure module they name the Trans-lunar Hub for Exploration, ISRU, and Development – or THEIA, after the proposed object that crashed into the Earth that created the Moon as we all know it right this moment. Their submission was a part of the NASA Revolutionary Aerospace Methods Ideas – Educational Linkage undertaking, the place groups from varied tutorial establishments submitted papers specializing in the theme of Sustained Lunar Evolution for 2024.
To be clear, THEIA shouldn’t be meant to function the central hub of NASA’s lunar exploration actions. The duty would nonetheless go to the Artemis base the company has been engaged on. It’s meant to function a hub for 4 predominant issues that the workforce believes each long-term lunar mission will want: energy, communications, transportation, and In-situ useful resource utilization (ISRU).
The undertaking’s mission necessities embody offering native positioning, communications, and energy to an space surrounding the lunar south pole. Numerous organizations are growing a number of items of infrastructure to take action.

First can be the supply technique to get there—like a lot of the general Artemis undertaking, THEIA would depend on supply from a SpaceX Starship. The workforce calculated the preliminary launch necessities to get a fundamental setup up and operating to be round 73 tons, properly under the brink of 100 tons the rocket is anticipated to have the ability to carry to the lunar floor.
That first set of apparatus would come with two different very important items of infrastructure – some LUNARSABER poles and robots to set them up. We beforehand did a whole article on the LUNARSABER undertaking from Honeybee Robotics. Nonetheless, as a succinct overview, it’s an extendable tower with photo voltaic panels alongside its sides to gather vitality. Then, it makes use of a collection of transmitters and receivers at its high to broadcast each energy and communication alerts. They will additionally bounce alerts between two towers, making a fundamental mesh community on the lunar floor.
A LUNARSABER is crucial for supplying energy and communications, however the UIUC workforce wants robotic assist to deploy it. They counsel utilizing a number of robotic rovers, together with a multilimbed one designed on NASA’s Athlete prototype and a extra conventional lunar rover based mostly across the present Lunar Terrain Automobile contract NASA has excellent, with a number of firms nonetheless vying to supply the ultimate design.
Different important infrastructure items embody floor antennas to transmit information and communications again to the Lunar Gateway and habitats that might permit each scientific experiments to function and, ultimately, crew to reside. An important further a part of THEIA’s design philosophy is that there needs to be area for experiments to function inside a semi-controlled atmosphere.
That will nonetheless be a very long time from now, with authentic missions to launch THEIA not deliberate till 2035 and crewed missions to comply with years later. Nonetheless, THEIA was initially drawn up by a bunch of undergraduates, who offered a technical paper in response to the NASA RASC-AL proposal. It was one in every of many such proposals that resulted in teams from Virginia Polytechnic, the College of Maryland, and South Dakota College successful prizes. We’ll take a look at a few of the different tasks submitted by groups shortly, however congratulations to the UIUC workforce, who made it by way of the competitors as a finalist, for the trouble they put into theirs.
