TL;DR: The Spectral and Photometric Imaging Receiver (SPIRE) as discussed by the authors is the Herschel Space Observatory's submillimetre camera and spectrometer, which is used for scan-mapping, whereby the field of view is scanned across the sky to achieve full spatial sampling and to cover large areas.

TL;DR: The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14~May 2009 and scanned the microwave and submillimetre sky continuously between 12~August 2009 and 23~October 2013 as discussed by the authors.

TL;DR: Spectra and high-resolution images obtained by the Huygens Probe Descent Imager/Spectral Radiometer instrument in Titan's atmosphere reveal the traces of once flowing liquid, and like Earth, the brighter highland regions show complex systems draining into flat, dark lowlands.

TL;DR: The Composite Infrared Spectrometer (CIRS) is a remote-sensing Fourier transform spectrometer on the Cassini orbiter that measures thermal radiation over two decades in wavenumber, with a spectral resolution that can be set from 0.5 to 15.5 cm− 1.

TL;DR: In this paper, the authors analyzed Titan observations performed by the Infrared Space Observatory (ISO) in the range 7-30 μm and obtained the monodeuterated methane-averaged abundance and retrieved a D/H isotopic ratio of 8.7−1.
