North Ray is one of the high-albedo ray craterlets near Apollo 16's landing site which are already observable through common telescopes. The best time to observe both ray craterlets (North Ray and South Ray) is during Full Moon. It is not known if the much smaller Baby Ray (near South Ray) is also detectable through powerful telescopes. A good specialist of telescopic Hi-Res webcam photography could come up with the answer...

Additional Information

  • The Landing Site Name North Ray is plotted on Site Traverses chart 78D2S2.
  • Astronauts John Young and Charlie Duke (Apollo 16) visited a huge boulder on the southeastern part of North Ray's rim. They called that boulder House Rock (or Big Black Boulder).
  • AS16-106-17336 shows John Young and the "Big Black Boulder" in the distance. On this photograph, less than the upper half of the boulder is visible!
  • AS16-116-18603 is a color Hasselblad of the boulder. The vertical streaks are photographic blemishes.
  • AS16-106-17344 is one of the few close ups of that boulder. Unfortunately, there was not enough time to explore all sides of it.


Astronaut-named feature, Apollo 16 site.
