In addition to the new iBook, Hubble Space Telescope: Discoveries, NASA is also offering a second free-of-charge e-book through iTunes, titled James Webb Space Telescope Science Guide. Like the Hubble book, this is a highly interactive e-book, which features video, image galleries, and more to tell the story of the James Webb Space Telescope.
The James Webb Space Telescope, currently scheduled to be launched into Earth orbit around 2018, will be optimized for observations in the infrared portion of the electromagnetic spectrum. It is designed to focus on objects in the most distant part of the Universe and to find stars and solar systems in formation behind dust clouds. The telescope is named after NASA's second Administrator, James E. Webb, who played an integral part in the program to land Americans on the Moon in Project Apollo.
