Artemis III Hardware Requirements & Site Compatibility
Amidst intense deliberation on landing sites for Artemis III, understanding the technical specifications of space hardware comes into focus. As our technological landscapes continually evolve, the hardware capabilities currently at our disposal can notionally stretch to facilitate landing just about anywhere. Yet, there is an intricate matrix of factors that link the capabilities of Artemis III to an ideal landing site.
Artemis III will use the Orion spacecraft – a versatile spacecraft designed for a comprehensive suite of space missions. It’s outfitted with advanced navigation, propulsion, life support, and communication systems. An essential component in deciding on a landing site is the range of the Orion European Service Module (ESM) propulsion system. Its capability to manage trajectory alterations plays a pivotal role in selecting a site within its operational boundaries.
The lunar terrain beneath Artemis III’s descent engine practically glows, with the effects being most pronounced on fine and dense regolith. This lunar soil, once uplifted, has the potential to be a hazard. It could impair the vision of the astronauts during landing or even damage the spacecraft. Therefore, the characteristics of lunar soil at the prospective site have profound implications on the selection process.
Exploration EVA suits—extravehicular activity suits—will be worn by Artemis III astronauts. The EVA suits are designed to combat the rigors of the lunar environment. They are equipped with life support systems and offer robust protection against temperature extremes, micrometeorite impacts, and lunar dust. These suits, however, have limitations in traversing extreme terrains. Therefore, the nature of the terrain, the angles of slope, and the spatial distribution of hazards such as boulders and craters are vital pieces in the complex puzzle of site selection.
The Artemis III also comprises a lunar ascent module – the apparatus designed to launch astronauts from the Moon’s surface back to the Gateway. This requires accurate understanding of gravitational anomalies on the Moon and how they will interact with and possibly affect the launch of the ascent module. Therefore, the potential site must have gravitational attributes that are compatible with the ascent module’s flight requisites.
Lastly, the Artemis III mission will also employ various rovers for surface explorations. The rovers are designed for scientific explorations and to assess available resources on the lunar surface. The operational limitations of these rovers vis-à-vis slopes, lunar rocks, and dusty terrains closely impinges on the choice of the landing site.
