Comic books and graphic novels are one of the newest fully fledged art forms, a vibrant, hybrid medium birthed in America and brimming with all the wildly experimental vigor of youth. Traditionally associated with children's narratives and the object of condescension and ridicule, they have only recently captured academic attention. What is happening with teaching and scholarship in the realm of comics is a very good case study of the blurring and shifting of disciplinary boundaries that is happening throughout academia, as well as the introduction of new material into the canon as it gains respect. Developing a pedagogical approach to comics and focusing students' attention on how to analyze the language of sequential storytelling will help them move through a world where visual and verbal content increasingly converge and where visual literacy is as important as verbal literacy. The author reviews a new anthology of essays edited by Stephen E. Tabachnick for the MLA series Options for Teaching--"Teaching the Graphic Novel." "Teaching the Graphic Novel" is an excellent resource for teachers dealing with comics in the classroom. The anthology is written by and for academics who want to understand how to approach graphic novels and not by or for cartoonists who want to teach.

The principal challenges in providing effective deep space navigation, telecommunications, and information management architectures and designs for Mars exploration support are presented. The fundamental objectives are to provide the mission with the means to monitor and control mission elements, obtain science, navigation, and engineering data, compute state vectors and navigate, and to move these data efficiently and automatically between mission nodes for timely analysis and decision making. New requirements are summarized, and related issues and challenges including the robust connectivity for manned and robotic links, are identified. Enabling strategies are discussed, and candidate architectures and driving technologies are described.

This paper discusses typical manned Mars exploration needs for telecommunications, including preliminary navigation support functions. It is a brief progress report on an ongoing study program within the current NASA JPL Deep Space Network (DSN) activities. A typical Mars exploration case is defined, and support approaches comparing microwave and optical frequency performance for both local in situ and Mars-earth links are described. Optical telecommunication and navigation technology development opportunities in a Mars exploration program are also identified. A local Mars system telecommunication relay and navigation capability for service support of all Mars missions has been proposed as part of an overall solar system communications network. The effects of light-time delay and occultations on real-time mission decision-making are discussed; the availability of increased local mass data storage may be more important than increasing peak data rates to earth. The long-term frequency use plan will most likely include a mix of microwave, millimeter-wave and optical link capabilities to meet a variety of deep space mission needs.

The Deep Space Network (DSN) is responsible for the acquisition of in-situ science and engineering measurements and navigation data from spacecraft exploring the Solar System. Key characteristics of the DSN design approach, the costs to upgrade performance over the past several decades, and some fundamental constraints on performance are discussed. The specific 70-meter upgrade task and the resulting overall benefits to Voyager-Neptune and the mission set are addressed.
