Document 2: Herschel Space Observatory: The Herschel Space Observatory was a space observatory built and operated by the European Space Agency (ESA). It was active from 2009 to 2013, and was the largest infrared telescope ever launched, carrying a 3.5 m mirror and instruments sensitive to the far infrared and submillimetre wavebands (55–672 µm). "Herschel" was the fourth and final cornerstone mission in the Horizon 2000 programme, following "SOHO"/"Cluster II", "XMM-Newton" and "Rosetta". NASA is a partner in the "Herschel" mission, with US participants contributing to the mission; providing mission-enabling instrument technology and sponsoring the NASA Herschel Science Center (NHSC) at the Infrared Processing and Analysis Center and the Herschel Data Search at the Infrared Science Archive.
Document 3: Infrared Science Archive: The Infrared Science Archive (IRSA) curates the science products of NASA's infrared and submillimeter projects, such as the Spitzer Space Telescope, the Wide-field Infrared Survey Explorer (WISE), the Infrared Astronomical Satellite (IRAS), and the Two Micron All-Sky Survey (2MASS). IRSA also serves data from infrared and submillimeter European Space Agency missions with NASA participation, including the Infrared Space Observatory (ISO), Planck, and the Herschel Space Observatory. s of 2014 , IRSA provides access to more than 20 billion astronomical measurements, including all-sky coverage in 20 bands, spanning wavelengths from 1 micron to 10 millimeters. Approximately 10% of all refereed astronomical journal articles cite data sets curated by IRSA.
Document 4: Johannes Kepler ATV: The "Johannes Kepler" ATV, or Automated Transfer Vehicle 002 (ATV-002), was an unmanned cargo spacecraft built to resupply the International Space Station (ISS). It was launched on 16 February 2011 by the European Space Agency (ESA). "Johannes Kepler" carried propellant, air and dry cargo weighing over 7000 kg , and had a total mass of over 20000 kg , making it, at the time, the heaviest payload launched by the ESA. The spacecraft was named after the 17th-century German astronomer Johannes Kepler.
Document 5: Constellation-X Observatory: The Constellation-X Observatory (HTXS or Con-X) was a mission concept for an X-ray space observatory to be operated by NASA; in 2008 it was merged with ESA and JAXA efforts in the same direction to produce the International X-ray Observatory project, announced on July 24, 2008.
Document 6: List of space telescopes: This list of space telescopes (astronomical space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared, microwave and radio. Telescopes that work in multiple frequency bands are included in all of the appropriate sections. Space telescopes that collect particles, such as cosmic ray nuclei and/or electrons, as well as instruments that aim to detect gravitational waves, are also listed. Missions with specific targets within the Solar System (e.g. our Sun and its planets), are excluded; see List of Solar System probes for these, and List of Earth observation satellites for missions targeting our planet.
Document 7: TIMED: The TIMED (Thermosphere Ionosphere Mesosphere Energetics and Dynamics) is an orbiter mission dedicated to study the dynamics of the Mesosphere and Lower Thermosphere (MLT) portion of the Earth's atmosphere. The mission was launched from Vandenberg Air Force Base in California on December 7, 2001 aboard a Delta II rocket launch vehicle. The project is sponsored and managed by NASA, while the spacecraft was designed and assembled by the Applied Physics Laboratory at Johns Hopkins University. The mission has been extended several times, and has now collected data over an entire solar cycle, which helps in its goal to differentiate the Sun's effects on the atmosphere from other effects.
Document 8: Christer Fuglesang: Arne Christer Fuglesang (] ) (born March 18, 1957 in Stockholm) is a Swedish physicist and an ESA astronaut. He was first launched aboard the STS-116 Space Shuttle mission on December 10, 2006, at 01:47 GMT, making him the first Swedish citizen in space.
Document 9: Svinfylking: The Svinfylking, Old Norse for 'Swine Array' or 'Boar Snout', was a version of the wedge formation used in Iron Age Scandinavia then by the Vikings, and by the Germanic peoples during the Germanic Iron Age where it was known as the "Schweinskopf" or 'Swine's Head'. Its invention was attributed to the god Odin.
Document 10: Odin (satellite): Odin is a Swedish satellite working in two disciplines: astrophysics and aeronomy, and it was named after Odin of Norse mythology. Within the field of astrophysics, Odin was used until the spring of 2007 aiding in the study of star formation. Odin is still used for aeronomical observations, including exploration of the depletion of the ozone layer and effects of global warming. In February 2016 it celebrated 15 years in Earth orbit, and was still functioning nominally.
Document 11: Hubble European Space Agency Information Centre: The Hubble European Space Agency Information Centre (HEIC) is a science communication office, established at the Space Telescope - European Coordinating Facility (ST-ECF) in Munich, Germany late in 1999. This initiative was taken so as to fulfil the NASA/ESA Hubble Space Telescope (HST) outreach and education tasks for the European Space Agency (ESA), as outlined in an agreement between NASA and ESA.
Document 12: Old Norse religion: Old Norse religion developed from early Germanic religion during the Proto-Norse period, when the North Germanic peoples separated into a distinct branch of the Germanic peoples. It was displaced by Christianization of the North Germanic peoples. Scholars reconstruct aspects of North Germanic religion by historical linguistics, archaeology, toponymy, and records left by North Germanic peoples, such as runic inscriptions in the Younger Futhark, a distinctly North Germanic extension of the runic alphabet. Numerous Old Norse works dated to the 13th century record Norse mythology, a component of North Germanic religion.
Document 13: BLAST (telescope): The Balloon-borne Large Aperture Submillimeter Telescope (BLAST) is a submillimeter telescope that hangs from a high-altitude balloon. It has a 2-meter primary mirror that directs light into bolometer arrays operating at 250, 350, and 500 µm. These arrays were developed for the SPIRE instrument on the Herschel Space Observatory. The project is carried out by a multi-university consortium headed by the University of Pennsylvania and which also includes University of Toronto, Brown University, the University of Miami, the University of British Columbia, JPL, INAOE, and Cardiff University. The third flight of BLAST in Antarctica was a scientific success, but much of telescope was destroyed after landing. It has been rebuilt for a flight from Antarctica in the 2010-11 austral summer. This most recent flight of BLAST (aka BLAST-Pol) has a polarimeter to observe the polarized light from star forming cores. The light is polarized due to magnetic fields. It is thought that the magnetic fields inhibit the collapse of the cores. The Herschel Space Observatory does not have a polarimeter.
Document 14: Österplana 065: Österplana 065 (Öst 65) is an Ordovician fossil meteorite found in the Thorsberg quarry in Sweden on June 26, 2011 and scientifically described in 2016. Measuring 8×6.5×2 cm, it impacted the Earth 470 million years ago. According to the naming conventions of the Meteoritical Society, the meteorite was named after the locality at which it was found, Österplana.
Document 15: Heavens-Above: Heavens-Above is a non-profit website developed and maintained by Chris Peat as "Heavens-Above GmbH". The web site is dedicated to helping people observe and track satellites orbiting the Earth without the need for optical equipment such as binoculars or telescopes. It provides detailed star charts showing the trajectory of the satellites against the background of the stars as seen during a pass. Special attention is paid to the ISS, Iridium flares and other satellites. Space shuttle missions were tracked until the program was retired in July 2011. The website also offers information on currently visible comets, asteroids, planet details, and other miscellaneous information.
