South Pole-Aitken Basin
Feasibility Assessment of All Science Concepts within South Pole-Aitken Basin INTRODUCTION While most of the NRC 2007 Science Concepts can be investigated across the Moon, this chapter will focus on specifically how they can be addressed in the South Pole-Aitken Basin (SPA). SPA is potentially the largest impact crater in the Solar System (Stuart-Alexander, 1978), and covers most of the central southern farside (see Fig. 8.1). SPA is both topographically and compositionally distinct from the rest of the Moon, as well as potentially being the oldest identifiable structure on the surface (e.g., Jolliff et al., 2003). Determining the age of SPA was explicitly cited by the National Research Council (2007) as their second priority out of 35 goals. A major finding of our study is that nearly all science goals can be addressed within SPA. As the lunar south pole has many engineering advantages over other locations (e.g., areas with enhanced illumination and little temperature variation, hydrogen deposits), it has been proposed as a site for a future human lunar outpost. If this were to be the case, SPA would be the closest major geologic feature, and thus the primary target for long-distance traverses from the outpost. Clark et al. (2008) described four long traverses from the center of SPA going to Olivine Hill (Pieters et al., 2001), Oppenheimer Basin, Mare Ingenii, and Schrödinger Basin, with a stop at the South Pole. This chapter will identify other potential sites for future exploration across SPA, highlighting sites with both great scientific potential and proximity to the lunar South Pole. -

ENG 402: Advanced Placement English Literature & Composition Summer Reading
ENG 402: Advanced Placement English Literature & Composition Summer Reading Dear students, Welcome to Advanced Placement English Literature and Composition! You have chosen a challenging, but rewarding path. This course is for students with intellectual curiosity, a strong work ethic, and a desire to learn. I know all of you have been well prepared for the “Wonderful World of Literature” in which we will delve into a wide selection of fiction, drama, and poetry. In order to prepare for the course, you will complete a Summer Reading Assignment prior to returning to school in the fall. Your summer assignment has been designed with the following goals in mind: to help you build confidence and competence as readers of complex texts; to give you, when you enter class in the fall, an immediate basis for discussion of literature – elements like narrative viewpoint, symbolism, plot structure, point of view, etc.; to set up a basis for comparison with other works we will read this year; to provide you with the beginnings of a repertoire of works you can write about on the AP Literature Exam next spring; and last but not least, to enrich your mind and stimulate your imagination. If you have any questions about the summer reading assignment (or anything else pertaining to next year), please feel free to email me ([email protected]). I hope you will enjoy and learn from your summer reading. I am looking forward to seeing you in class next year! Have a lovely summer!
