Which was launched first, the Swedish satellite Odin or the Herschel Space Observatory?
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.
Herschel (Mimantean crater) Herschel is a huge crater in the leading hemisphere of the Saturnian moon Mimas, on the equator at 100° longitude. It is named after the eighteenth century astronomer William Herschel, who discovered Mimas in 1789.
