Uv Astronomy with Small Satellites
UV ASTRONOMY WITH SMALL SATELLITES Pol Ribes-Pleguezuelo(1), Fanny Keller(1), Matteo Taccola(1) (1) ESA-ESTEC, Keplerlaan 1, 2201AZ Noordwijk, Netherlands, [email protected], [email protected], [email protected] ABSTRACT Small satellite platforms with high performance avionics are becoming more affordable. So far, with a few exceptions, small satellites have been mainly dedicated to earth observation. However, astronomy is a fascinating field with a history of large missions and a future of promising large mission candidates. This prompts many questions; can the recent affordability of small satellites change the landscape of space astronomy? What are the potential applications and scientific topics of interest, where small satellites could be instrumental for astronomy? What are the requirements and objectives that need to be fulfilled to successfully address the astronomical investigations of interest? Which kind of instrumentation suits the small platforms and the scientific use cases best? This paper discusses possible scientific use cases that can be achievable with a relatively small telescope aperture of 36 cm, as an example. The result of this survey points to a specific niche market -astronomy observation in the UV spectral range. UV astronomy is a research field which has had valuable scientific impact. It is, however, not the focus of many current or past astronomical investigations. UV astronomy measurements cannot be made from earth, due to atmospheric absorption in this spectral range. Only a few current space missions, such as the Hubble and Gaia, cover the UV spectral range, some of them only in the near-UV (NUV). The research field is currently sparsely addressed but of scientific interest for a large community. -

What Is CHEOPS?
Swiss and ESA satellite CHEOPS launching soon! CHEOPS will be launching into space on the 17th of December! You may be wondering: what is CHEOPS? CHEOPS stands for CHaracterising ExOPlanet Satellite. Its goal is to study transits of already-known exoplanets to gain more knowledge about them. What type of information are we looking for? Scientists want to know detailed information about planets outside our Solar System, such as the mass, planet size, and density, which will in turn help to figure out the composition of these exoplanets. Studying exoplanet composition and their atmospheres is important especially for astrobiology. A planet’s chemical composition can affect its habitability for life as we know it. Scientists usually look for biosignatures such as the presence of methane or oxygen in the planet’s atmosphere, which could indicate presence of past or present life. Artist’s impression of CHEOPS. Credits: ESA / ATG medialab. The major contributors CHEOPS is a collaboration between ESA and the Swiss Space Office. The mission was proposed and is now headed by Prof. Willy Benz, from the University of Bern, which houses the mission’s consortium. The science operations consortium is at the University of Geneva, where they have many collaborators, such as the Swiss Space Center at EPFL. As it is an ESA endeavour, many other European institutions are also contributing to the mission. For example, the mission operations consortium is located in Torrejón de Ardoz, Spain. The launch The satellite has already been shipped to Kourou, French Guiana, where it will be launched by the ESA spaceport. -
Cheops Cheops
cheops cheops Assemble your own planet watcher Paper Model Scale 1:15 About CHEOPS The CHaracterising ExOPlanet Satellite, or CHEOPS, is a space science mission dedicated to the study of known exoplanets orbiting bright, nearby stars. It will use the technique of ultra-high precision photometry to measure accurate sizes of a large sample of Earth to Neptune-sized planets. By combining the accurate sizes determined by CHEOPS with existing mass measurements, it will be possible to establish the bulk density and composition of the planets; these, together with information on the host stars and the planets’ orbits will be used to determine the planets' formation and evolutionary history. CHEOPS is a small satellite with a total launch mass of approximately 300 kg and dimensions of 1.55m (height) x 1.49m (width, measured from solar array edge to edge) x 1.4m (depth). The dark colours used in this paper model are representative of the true colours of the various spacecraft components. CHEOPS is a partnership between the European Space Agency (ESA) and Switzerland. REQUIRES: SCISSORS AND GLUE. 1. Assemble the Platform Body a) Cut out all the pieces for the Platform Body. b) Assemble the Platform Body (page 6), folding the side panels and gluing them via their tabs. Close the Platform Body by folding and gluing the top side of the platform. c) Fold the Satellite Interface Ring (page 7) along the length and fold the tabs at 90°. Bend the paper strip in a circle and close it via the gluing tab. d) Position the Satellite Interface Ring on the bottom side of the Platform Body and glue it with the tabs in the indicated position. -

This call was intended to find candidates for two medium-sized missions (M1, M2 class, launch around 2017) and one large mission (L1 class, launch around 2020). Fifty mission concept proposals were received in response to the first call. From these, five M-class and three L- class missions were selected by the SPC in October 2007 for assessment or feasibility studies. In July 2010, another call was issued, for a medium-size (M3) mission opportunity for a launch in 2022. Also about 50 proposals were received for M3 and 4 concepts were selected for further study.
