Condición: Good. Presumed First Edition, First printing. The format is approximately 11.75 inches by 8.75 inches. Front image is of the James Webb Space Telescope in an outer space environment. The reverse side has a line drawing of the observatory, some tabular data, and text discussing the mission the design and the team. Northrop Grumman business card of Lon Rains, Director of Strategic Communications stapled to top right corner. Sheet has some wear, small corner crease, and slight soiling. The mass of the James Webb Space Telescope (JWST) is about half that of the Hubble Space Telescope. Webb has a 21 ft-diameter gold-coated beryllium primary mirror made up of 18 separate hexagonal mirrors. The mirror has a polished area of (283 sq ft, of which 9.7 sq ft is obscured by the secondary support struts, giving a total collecting area of 273 sq ft. This is over six times larger than the collecting area of Hubble's 7.9 ft diameter mirror, which has a collecting area of 43 sq ft. The mirror has a gold coating to provide infrared reflectivity and this is covered by a thin layer of glass for durability. Webb is designed primarily for near-infrared astronomy, but can also see orange and red visible light, as well as the mid-infrared region, depending on the instrument being used. It can detect objects up to 100 times fainter than Hubble can, and objects much earlier in the history of the universe, back to redshift z 20 (about 180 million years cosmic time after the Big Bang). Hubble is unable to see further back than very early reionization at about z 11.1 (galaxy GN-z11, 400 million years cosmic time). The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars and the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets. Although the Webb's mirror diameter is 2.7 times larger than that of the Hubble Space Telescope, it produces images of comparable sharpness because it observes in the longer-wavelength infrared spectrum. The longer the wavelength of the spectrum, the larger the information-gathering surface required (mirrors in the infrared spectrum or antenna area in the millimeter and radio ranges) for an image comparable in clarity to the visible spectrum of the Hubble Space Telescope. The Webb was launched on 25 December 2021 on an Ariane 5 rocket from Kourou, French Guiana. In January 2022 it arrived at its destination, a solar orbit near the SunEarth L2 Lagrange point, about 930,000 miles from Earth. The telescope's first image was released to the public on 11 July 2022. The U.S. National Aeronautics and Space Administration (NASA) led Webb's design and development and partnered with two main agencies: the European Space Agency (ESA) and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center in Maryland managed telescope development, while the Space Telescope Science Institute in Baltimore on the Homewood Campus of Johns Hopkins University operates Webb. The primary contractor for the project was Northrop Grumman. Lon Rains was responsible for all External Communications, Media Relations, Advertising, and Marketing Communications for the Aerospace Systems Sector of Northrop Grumman.
