Hi all,

Pic of the Rotting Marsh - Palus Putredinis taken on 17 February last. Archimedes is just coming into the sunshine.

Sinus Lunicus is named for the Soviet probe, Lunik 2, which in 1959 was the first probe ever to "make contact" with another body - even if it was at several thousand miles an hour!

Crater Autolycus, is named for the ancient Greek astronomer although it does sound like some worrying biological process.

Aristillus is named for the Greek astronomer who accurately worked on meridian positions of stars.

Rimae Fresnel are a group of "graben" like the Vallis Alpes near crater Plato and formed apparently by surface stress. Named for the French optician, Augustin-Jean Fresnel famous for promoting the wave theory of light and also for the "Fresnel" lens, a stepped type of lens seen mostly in lighthouse lights and enabling the light to be seen at a farther distance than a "normal" lens.

Rima Hadley or Hadley Rille is hidden in the shadows of the Montes Apenninus and the site of Apollo 15 landing and the first lunar rover mission in July-August 1971. John Hadley (1682 - 1744) was an English instrument maker remembered for the invention of the Octant - a navigational theodolite - like instrument allowing accurate determinations of longitude at sea - er, provided you knew the time really precisely!
