Continued support for both ground-and space-based telescopic studies is an essential aspect of a program for the exploration of the trans-neptunian solar system. The highest priority for both ground-and space-based studies is significant access to existing and future moderate-to large-aperture telescopes equipped with modern instrumentation designed to meet the needs of planetary observers. Telescopes in the 2- to 4-meter class are ideally suited to searching for new KBOs. But larger telescopes (8 to 10 m) are required for spectroscopic studies of known KBOs.
Although access to suitable telescopes can provide much new data, with augmentations in a few critical areas ground-and space-based observations could provide even more information about the trans-neptunian solar system. These augmentations include:
Continued support for research and analysis programs and for relevant theoretical and laboratory studies is an essential component of a program of spacecraft and telescopic observations of the trans-neptunian solar system. Theoretical and laboratory studies of the physical and chemical processes that influence the structure and evolution of cold (<40 Kelvin), icy bodies located in the trans-neptunian region should be fully supported to enhance the scientific return from spacecraft missions and telescopic observations.
