NEAR-TERM SEI SCIENCE MISSIONS UTILIZING AN EVOLUTIONARY LUNAR TRANSPORTATION SYSTEM

An evolutionary program of space science missions for the lunar surface and the transportation system concept developed to deploy diem are described. Lunar-based science systems will evolve from simple, robotic instruments such as a lunar transit telescope (LTT) to large, observatory-class instruments like a 16-meter optical telescope assembled by astronauts at a lunar base. A transportation system concept to support the Space Exploration Initiative (SEI) and the deployment of these science payloads is described. Beginning with a post-Artemis lander capability, a modular approach to lunar landers is proposed as a way to maximize commonality and to support evolving SEI transportation requirements.
