Thanks, CR. I have now corrected the APOD text.

<<The C Ring is a wide but faint ring located inward of the B Ring. It was discovered in 1850 by William and George Bond, though William R. Dawes and Johann Galle also saw it independently. William Lassell termed it the "CREPE Ring" because it seemed to be composed of darker material than the brighter A and B Rings.>>

CREPE (n.) 1797, from French crêpe, from Old French crespe (14c.), from Latin crispa, fem. of crispus "curled, wrinkled". Meaning "small, thin pancake" is from 1877.

CRAPE (n.) 1630s, Englished spelling of crepe.

CRAPS (n.) 1843, from Louisiana French craps "the game of hazard," from an 18c. continental French corruption of English crabs, which was 18c. slang for "a throw of two or three" (the lowest throw).

CRAP (v.) "defecate," 1846, from one of a cluster of words generally applied to things cast off or discarded, all probably from Middle English crappe "grain that was trodden underfoot in a barn, chaff" (mid-15c.), from Middle French crape "siftings," from Old French crappe, from Medieval Latin crappa, crapinum "chaff." Despite folk etymology insistence, not from Thomas Crapper (1837-1910) who was, however, a busy plumber and may have had some minor role in the development of modern toilets. Crap (v.) as a variant of crop (v.) was noted early 19c, as a peculiarity of speech in Scotland and what was then the U.S. Southwest (Arkansas, etc.).

• Draw out yere sword, thou vile South'ron!
  Red wat wi' blude o' my kin!
  That sword it crapped the bonniest flower
  E'er lifted its head to the sun!
  [Allan Cunningham (1784-1842), "The Young Maxwell"]

<<William Lassell (18 June 1799 – 5 October 1880) was an English merchant and astronomer. He made his fortune as a beer brewer, which enabled him to indulge his interest in astronomy. He built an observatory at his house "Starfield" in West Derby, a suburb of Liverpool. There he had a 24-inch reflector telescope, for which he pioneered the use of an equatorial mount for easy tracking of objects as the Earth rotates. He ground and polished the mirror himself, using equipment he constructed.

In 1846 Lassell discovered Triton, the largest moon of Neptune, just 17 days after the discovery of Neptune itself by German astronomer Johann Gottfried Galle. In 1848 he independently co-discovered Hyperion, a moon of Saturn. In 1851 he discovered Ariel and Umbriel, two moons of Uranus.

In 1855, he built a 48-inch telescope, which he installed in Malta because of the observing conditions that were better than in often-overcast England. On his return to the UK after several years in Malta he moved to Maidenhead and operated his 24-inch telescope in an observatory there. The 48-inch telescope was dismantled and was eventually scrapped.

Lassell was a Fellow of the Royal Astronomical Society (FRAS) from 1839, won the Gold Medal of the Royal Astronomical Society in 1849, and served as its president for two years starting in 1870. He was elected a Fellow of the Royal Society (FRS) in 1849 and won their Royal Medal in 1858. Lassel was also a Fellow of the Royal Society of Literature (FRSL). He was furthermore elected an honorary Fellow of the Society of Sciences of Upsala, and received an honorary LL.D. degree from the University of Cambridge.

Lassell died in Maidenhead in 1880. Upon his death, he left a fortune of £80,000 (roughly equivalent to £7,200,000 in 2015). His telescope was presented to the Royal Observatory in Greenwich. The crater Lassell on the Moon, a crater on Mars, the asteroid 2636 Lassell and a ring of Neptune are named in his honour.>>

As I recall, he won the debate, on interesting grounds in retrospect: the winning argument was simply that, although it was possible, it would simply cost too much!

It's a good argument, but it overlooked the fact that going to the Moon was fundamentally a political and military decision framed by the Cold War, and as such, didn't follow the normal rules of economics.

What a difference Sputnik made in 1957.

The future will produce better & cheaper space craft and better & cheaper virtual reality such everyone on this planet will be able to enjoy the astronaut experience.
