[17] At 3.5 metres wide (11 ft), Herschel carried the largest optical telescope ever deployed in space. Scientific Instrument(s) - Photoconductor Array … Herschel will be equipped with a … For additional ESA and external Herschel related web sites see link buttons above and "Useful links".Herschel was launched on 14 May 2009! 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. The absolute pointing error needs to be less than 3.7 arc seconds. The app below allows you to design your own space telescope, based on a range of “mission scenarios”. [16], Herschel specialised in collecting light from objects in the Solar System as well as the Milky Way and even extragalactic objects billions of light-years away, such as newborn galaxies, and was charged with four primary areas of investigation:[17], During the mission, Herschel "made over 35,000 scientific observations" and "amass[ed] more than 25,000 hours' worth of science data from about 600 different observing programs". Pilbratt ... [et al.] [42][43], An October 2011 report published in Nature states that Herschel's measurements of deuterium levels in the comet Hartley 2 suggests that much of Earth's water could have initially come from cometary impacts. It is revealing new information about the earliest, most It has also taken a unique look at our own solar system. [32][33][34] The orbit's perigee was 270.0 km (intended 270.0±4.5), apogee 1,197,080 km (intended 1193622±151800), inclination 5.99 deg (intended 6.00±0.06). It comprises a three-band camera operating at 250, 350 and 500 microns, and an imaging Fourier Transform Spectrometer cover-ing 194-671 microns. The Herschel Space Observatory, the world's largest infrared space telescope, has reached the end of its cosmic life after nearly four years in orbit. [39], In July 2010 a special issue of Astronomy and Astrophysics was published with 152 papers on initial results from the observatory. Herschel Space Observatory. All spacecraft units on the SVM are redundant. 1. Structurally, the Herschel and Planck SVMs are very similar. [48] The detection was made by using the far-infrared abilities of the Herschel Space Observatory. L'Herschel Space Observatory è una missione dell'Agenzia Spaziale Europea. SPIRE's bolometers are of a "spider web" design developed by Co-Investigator Dr. James Bock of JPL. Herschel Space Observatory Operations Scenario Document DocRef Herschel/HSC/DOC/0114 Issue 1.2 Date 17 Mar 2003 PageNo iv HSC 1 2 17 Mar 2003 In the Herschel HSC/ICC status review held in Nov/Dec 2002 it was reiterated that the top-level documents, [47], On 22 January 2014, ESA scientists reported the detection, for the first definitive time, of water vapor on the dwarf planet, Ceres, largest object in the asteroid belt. [54], NASA's proposed Origins Space Telescope (OST) would also observe in the far-infrared band of light. Many aspects of the Herschel Space Observatory are revolutionary. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. SPIRE, the Spectral and Photometric Imaging Receiver, is the submillimetre camera and spectrometer on board the Herschel Space Observatory. 1.4: An artist’s impression of the ESA’s Herschel Space Observatory (HSO). De telescoop is in een baan om het tweede Lagrangepunt gebracht. The lid had to remain closed until the telescope was well into space to prevent contamination. On 29 April 2013, ESA announced that Herschel's supply of liquid helium, used to cool the instruments and detectors on board, had been depleted, thus ending its mission. This thesis deals with the verification, characterization and calibration of the optical performance of Herschel-HIFI. Read. This function is performed by the attitude control computer (ACC) which is the platform for the ACMS. [13] At the time of the announcement, Herschel was approximately 1.5 million km from Earth. The Herschel spacecraft is three-axis stabilized.
