Constellation Architecture Team-Lunar Scenario 12.0 Habitation Overview

Abstract

This paper will describe an overview of the Constellation Architecture Team Lunar Scenario 12.0 (LS-12) surface habitation approach and concept performed during the study definition. The Lunar Scenario 12 architecture study focused on two primary habitation approaches: a horizontally-oriented habitation module (LS-12.0) and a vertically-oriented habitation module (LS-12.1). This paper will provide an overview of the 12.0 lunar surface campaign, the associated outpost architecture, habitation functionality, concept description, system integration strategy, mass and power resource estimates. The Scenario 12 architecture resulted from combining three previous scenario attributes from Scenario 4 "Optimized Exploration", Scenario 5 "Fission Surface Power System" and Scenario 8 "Initial Extensive Mobility" into Scenario 12 along with an added emphasis on defining the excursion ConOps while the crew is away from the outpost location. This paper will describe an overview of the CxAT-Lunar Scenario 12.0 habitation concepts and their functionality. The Crew Operations area includes basic creNv accommodations such as sleeping, eating, hygiene and stowage. The EVA Operations area includes additional EVA capability beyond the suitlock function such as suit maintenance, spares stowage, and suit stowage. The Logistics Operations area includes the enhanced accommodations for 180 days such as enhanced life support systems hardware, consumable stowage, spares stowage, interconnection to the other habitation elements, a common interface mechanism for future growth, and mating to a pressurized rover or Pressurized Logistics Module (PLM). The Mission & Science Operations area includes enhanced outpost autonomy such as an IVA glove box, life support, medical operations, and exercise equipment.

Space Logistics Modeling and Simulation Analysis using SpaceNet: Four Application Cases

“…Scenario 12 evolved from the confluence of three scenarios: Scenario 4 (Optimized Exploration), Scenario 5 (Fission Surface Power System), and Scenario 8 (Initial Extensive Mobility). 9,10 In Scenario 12, successive missions at a rate of about three per year deliver infrastructure components to an outpost, building up to full capability within six years.…”

A Logistics Analysis and Control of Distributed Life Support Systems for High-Mobility Exploration

“…Hence, minimizing the problem expressed in Eqs. (8) and (2) to (6) is equivalent to independently minimizing partial problems which are expressed using Eqs. (9), and (2) to (6) relative to logistics carrier k.…”

An overnight habitat for expanding lunar surface exploration

“…The earliest future lunar missions are assumed to be comparable in capability and scope to the late Apollo missions. Rather than the large pressurized roving vehicles and permanent base envisioned under the Constellation program [5,6], this paper assumes sortie missions with a modest increase in landing mass and surface duration compared to the late Apollo missions. In contrast to previous lunar habitat designs, for instance the Lunar Stay Time Extension Module [7], this system is designed to dramatically increase scientific capabilities with a modest increase in Apollo program designs.…”
