The XMM-Newton SAS - Distributed Development and Maintenance of a Large Science Analysis System: a Critical Analysis
Astronomical Data Analysis Software and Systems XIII ASP Conference Series, Vol. 314, 2004 F. Ochsenbein, M. Allen, and D. Egret, eds. The XMM-Newton SAS - Distributed Development and Maintenance of a Large Science Analysis System: A Critical Analysis Carlos Gabriel1, John Hoar1, Aitor Ibarra1, Uwe Lammers2, Eduardo Ojero1, Richard Saxton1, Giuseppe Vacanti2 XMM-Newton Science Operations Centre, Science Operations and Data Systems Division of ESA, European Space Agency Mike Denby, Duncan Fyfe, Julian Osborne Department of Physics and Astronomy, University of Leicester, Leicester, LE1 7RH, UK Abstract. The XMM-Newton Scientific Analysis System (SAS) is the software used for the reduction and calibration of data taken with the XMM-Newton satellite instruments leading to almost 400 refereed scien- tific papers published in the last 2.5 years. Its maintenance, further devel- opment and distribution is under the responsibility of the XMM-Newton Science Operations Centre together with the Survey Science Centre, rep- resenting a collaborative effort of more than 30 scientific institutes. Developed in C++, Fortran 90/95 and Perl, the SAS makes large use of open software packages such as ds9 for image display (SAO-R&D Software Suite), Grace, LHEASOFT and cfitsio (HEASARC project), pgplot, fftw and the non-commercial version of Qt (TrollTech). The combination of supporting several versions of SAS for multiple platforms (including SunOS, DEC, many Linux flavours and MacOS) in a widely distributed development process which makes use of a suite of ex- ternal packages and libraries presents substantial issues for the integrity of the SAS maintenance and development. A further challenge comes from the necessity of maintaining the flexibility of a software package evolving together with progress made in instrument calibration and anal- ysis refinement, whilst at the same time being the source of all official products of the XMM-Newton mission. -

SUCCESSES of the HUBBLE SPACE TELESCOPE, 18Th February 2005 Astronomical History the Hubble Telescope Has Been a Major Tool for the Last Fifteen Years
SUCCESSES OF THE HUBBLE SPACE TELESCOPE, 18th February 2005 Astronomical History The Hubble telescope has been a major tool for the last fifteen years. However, astronomy is as old as man – the earliest known good star map was by Hipparchus 2500 years ago, and a Roman statue (now in Naples) is of Atlas supporting a celestial globe. In 1610 Galileo made the first telescope, opening up the sky; he was able to see the moons of Jupiter, which clearly orbited Jupiter – not Earth, then considered the absolute centre of the universe… Larger telescopes were soon built, with long tubes to accommodate the low curvature lenses that gave the best results – they were not easily manoeuvred. There is a large 28” Refractor at the Observatory in Greenwich, designated ROG, made in 1893 but on an 1859 mount, which even in London’s atmosphere is useful for planetary observation. In 19thC astronomers began to study not just the location of celestial objects but what types they were. Reflecting Telescopes These use a mirror as the prime element to gather and focus light. Small ones were made in the late 18thC, then in the early 19thC Herschel designed one with an 18” mirror. Mirrors being supported from behind, are easier to mount than lenses can only be held at the edge; they can gather more light and give a brighter, sharper image. In 1948 the 200” (5 m) Hale telescope at Mount Palomar set a new standard, high up above much of the atmosphere for maximum clarity. This was built for traditional observation by eye; then longer exposures were made possible with photographic plates; now CCDs (Charge Coupled Detectors) give higher sensitivity. -

Science Enabled by High Precision Inertial Formation Flying

The common requirement is for formation flying of two spacecraft with the direction of their vector separation in inertial coordinates precisely controlled and accurately determined as a function of time. We consider here the scientific goals that could be achieved with such technology and review some of the proposals that have been made for specific missions. Types of instrumentation that will benefit from the development of this type of formation flying include 1) imaging systems, in which an optical element on one spacecraft forms a distant image recorded by a detector array on the other spacecraft, including telescopes capable of very high angular resolution; 2) systems in which the front spacecraft of a pair carries an occulting disk, allowing very high dynamic range observations of the solar corona and exoplanets; 3) interferometers, another class of instrument that aims at very high angular resolution and which, though usually requiring more than two spacecraft, demands very much the same developments. -
The Astronomy of Sir John Herschel
Introduction m m m m m m m m m m m Herschel’s Stars The Stars flourish, and in spite of all my attempts to thin them and . stuff them in my pockets, continue to afford a rich harvest. John Herschel to James Calder Stewart, July 17, 1834 n 2017, TRAPPIST-1, a red dwarf star forty light years from Earth, made headlines as the center of a system with not one or two but Iseven potentially habitable exoplanets.1 This dim, nearby star offers only the most recent example of verification of the sort of planetary system common in science fiction: multiple temperate, terrestrial worlds within a single star’s family of planets. Indeed, this discovery followed the an- nouncement only a few years earlier of the very first Earth-sized world orbiting within the habitable zone of its star, Kepler-186, five hundred light years from Earth.2 Along with other ongoing surveys and advanced instruments, the Kepler mission, which recently added an additional 715 worlds to a total of over five thousand exoplanet candidates, is re- vealing a universe in which exoplanets proliferate, Earth-like worlds are common, and planets within the habitable zone of their host star are far from rare.3 Exoplanetary astronomy has developed to the point that as- tronomers can not only detect these objects but also describe the phys- ical characteristics of many with a high degree of confidence and pre- cision, gaining information on their composition, atmospheric makeup, temperature, and even weather patterns. 3 © 2018 University of Pittsburgh Press.

The post- Accepted 8 November 2007 SDAT meanings of “social Darwinism” are the product of an unresolved Whiggish tension in Available online 6 March 2009 SDAT: Hofstadter championed economic reform over free markets, but he also condemned biology in social science, this while many progressive social scientists surveyed in SDAT JEL classification: offered biological justifications for economic reform. As a consequence, there are, in effect, B15 B31 two Hofstadters in SDAT. The first (call him Hofstadter1) disparaged as “social Darwinism” B12 biological justification of laissez-faire, for this was, in his view, doubly wrong. The sec- ond Hofstadter (call him Hofstadter2) documented, however incompletely, the underside Keywords: of progressive reform: racism, eugenics and imperialism, and even devised a term for it, Social Darwinism “Darwinian collectivism.” This essay documents and explains Hofstadter’s ambivalence in Evolution SDAT, especially where, as with Progressive Era eugenics, the “two Hofstadters” were at odds Progressive Era economics Malthus with each other. It explores the historiographic and semantic consequences of Hofstadter’s ambivalence, including its connection with the Left’s longstanding mistrust of Darwinism as apology for Malthusian political economy. -

X-Array Aperture Configuration in Planar Or Non-Planar Spacecraft
X-Array aperture configuration in planar or non-planar spacecraft formation for DARWIN/TPF-I candidate architectures Oswald Wallner, Klaus Ergenzinger, Reinhold Flatscher, Ulrich Johann Astrium GmbH, 88039 Friedrichshafen, Germany ABSTRACT The missions DARWIN and TPF-I (Terrestrial Planet Finder-Interferometer) aim at the search and analysis of terrestrial exo-planets orbiting nearby stars. The major technical challenge is the huge contrast ratio and the small angular separation between star and planet. The observational method to be applied is nulling interferom- etry. It allows for extinguishing the star light by several orders of magnitude and, at the same time, for resolving the faint planet. The fundamental performance of the nulling interferometer is determined by the aperture configuration, the effective performance is driven by the actual instrument implementation. The x-Array, an aperture configuration with 4 telescopes allowing for phase chopping and decoupling of the nulling and imaging properties, provides highest instrument performance. The scientific goals necessitate an instrument setup of high efficiency and utmost symmetry between the beams concerning optical path length, beam profile and state of polarization. Non-planar spacecraft formations allow for a simpler spacecraft design which comes at the cost of inherent constellation and beam asymmetry, of increased complexity of the beam relay optics and of instrumental errors synchronous to the planet signal demodulation frequency. Planar formations allow for perfect efficiency and symmetry but need deployable structures for the secondary mirror and the sunshield due to launcher accommodation constraints. We present a discussion of planar and non-planar implementations of the x-Array aperture configuration and identify for both the critical items and design drivers. -
