Robert Picardo, best known for playing an "Emergency Medical Hologram" (doctor) on the TV series "Star Trek: Voyager," belts out a classic opera tune in tribute to Cassini, which will plunge into Saturn's atmosphere on Friday (Sept. 15).
Cassini has been studying Saturn and its moons since 2004; some of its many discoveries include finding at least 101 water geysers spouting from the moon Enceladus and discovering evidence of prebiotic chemistry on the moon Titan.
The spacecraft, which is low on fuel, will make a deliberate plunge into Saturn to avoid the small possibility of it crashing into a potentially habitable moon, such as Enceladus. It will take measurements and transmit them as it flies down through the atmosphere, until the pressure of the atmosphere crushes the spacecraft.
To celebrate Cassini's contribution to science, space advocacy group The Planetary Society put together a YouTube video that in part features Picardo, who is on the board of directors for the organization. "Goodbye, Cassini – your mission's fini," sings Robert Picardo, to the tune of of the song "La donna è mobile" (Woman is Fickle) from the opera "Rigoletto," by the 19th-century Italian composer Giuseppe Verdi.
"Bravo, Cassini! Have some linguine. You showed us Saturn's rings and lots of pretty things," continues Picardo, as the video shows pictures of Saturn's rings and the geysers of Enceladus in the background.
The video also shows a quick view of the Huygens lander, which Cassini carried most of the way to Saturn's system. Huygens touched down on the surface of Titan in 2005. Huygens was designed to only last a short time on the surface, but it did yield information about Titan's clouds and atmospheric temperature. "Landed on Titan, it was exciting," Picardo sings.
"Your mission never failed to surprise, dazzled our eyes," Picardo continues, as the video turns its attention again to Cassini. "Now dive to Saturn — vaporize!"
