The ghost in the telescope : stories from the Herschel Space Observatory
\"The Ghost in the Telescope is an insider's account of the Herschel Space Observatory, which was built to answer the questions of how the stars and galaxies were born. Written in an engaging manner for a general audience, the book tells the stories of the telescope itself, the discoveries it made, and the engineers and astronomers who made and used it. The book, based on the author's own experience and interviews with the key astronomers and engineers, tells the story of the mission, from its original concept on a piece of paper in Venice to the moment after the end of the mission when the engineers had to decide whether to crash the spacecraft into the Moon. Containing some of the most spectacular pictures ever taken of the universe, the book describes all the major discoveries made with the telescope. The book also gives an account, accessible to anyone without previous scientific knowledge, of the latest research into the births of stars and galaxies. The book should interest anyone who is curious about astronomy, space missions, and how astronomy is done in practice. It is designed to be easy to read and does not require any previous scientific background\"-- Provided by publisher.

The pointing system of the Herschel space observatory
We present the activities carried out to calibrate and characterise the performance of the elements of attitude control and measurement on board the Herschel spacecraft. The main calibration parameters and the evolution of the indicators of the pointing performance are described, from the initial values derived from the observations carried out in the performance verification phase to those attained in the last year and half of mission, an absolute pointing error around or even below 1 arcsec, a spatial relative pointing error of some 1 arcsec and a pointing stability below 0.2 arsec. The actions carried out at the ground segment to improve the spacecraft pointing measurements are outlined. On-going and future developments towards a final refinement of the Herschel astrometry are also summarised. A brief description of the different components of the attitude control and measurement system (both in the space and in the ground segments) is also given for reference. We stress the importance of the cooperation between the different actors (scientists, flight dynamics and systems engineers, attitude control and measurement hardware designers, star-tracker manufacturers, etc.) to attain the final level of performance.

A half century of infrared astronomy — A personal recollection of the footprints in Japan
Since the new era of infrared astronomy was opened by the Two Micron Sky Survey by Neugebauer et al. in the early 1960s, about a half century has passed. During this time, observations have expanded rapidly and widely, to almost every field of astronomy, to reveal new perspectives on the universe. As a result, infrared astronomy has become one of the major branches of astronomy, along with optical, radio, X-ray as well as high-energy particle astronomy. In Japan, we started our infrared astronomical activities at a rather early time, under relatively poor technical and environmental conditions, and using somewhat unconventional methods to overcome these difficulties. Here, a brief survey is presented of developments concerning infrared astronomy during the past half century, while mainly recollecting our footprints in the stream of world activities.
