  • Although there seems to be nothing in the LPI's list of orbital Apollo photographs of Joy (and/or Hadley A), this little crater WAS frequently photographed during the mission of Apollo 15 in july 1971! - DannyCaes Jul 29, 2010
    • Orbital panoramic ITEK-camera frames AS15-P-9362 and AS15-P-9367 show Joy and also the curious craterlet on top of the hillock east of Joy itself. To see Joy and the small craterlet on top of the hillock nearby: scroll a little bit to the right.
    • Orbital mapping/metric Fairchild-camera photograph AS15-M-1535 shows Joy very near the frame's left margin (to the right of the small black triangle at the extreme left of the frame).
    • The Arizona State University's (ASU's) zoom-able scan of the same photograph (AS15-M-1535) shows Joy near the lower margin of the frame. Explore the small sharp looking pit on top of the hillock east of Joy!

Additional Information


  • Named for Alfred Harrison Joy ((September 23, 1882 – April 18, 1973), an American astronomer. Joy received the 1950 Bruce Medal of the Astronomical Society of the Pacific, and extensive links to information about him can be found there.
  • Hadley A, the former name, appears to have been introduced in the System of Lunar Craters.
  • Joy, for this feature, appears in the list of approved names published in IAU Transactions XVB (1973). The new honoree is not identified, but biographical information was unofficially reported in Ashbrook, 1974.
  • The replacement name was first used on LTO-41B3 (January 1974), for which it served as the chart title.
  • The association of the name with the present honoree is based on listings in early versions of the IAU Planetary Gazetteer.
  • "Pit of Joy" is my nickname for the small (and very sharp looking) craterlet on top of the hillock immediately east of Joy. - DannyCaes Jul 29, 2010
