Probe over Titan

The Huygens probe descends through Titan's murky, brownish-orange atmosphere of nitrogen and carbon-based molecules,
beaming its findings to the distant Cassini orbiter. The probe is equipped with a variety of scientific sensors to measure the
physical properties of the moon's atmosphere; it also carries an imaging device to return pictures of Titan's possibly
hydrocarbon-lake-dotted surface. Painting courtesy of the European Space Agency. (P-42357)
