   Shown above in the top photo is the  International Space Station
   (ISS)  transiting the  full mineral Moon as observed from the
   Republic of Moldovia on March 26, 2021. This crossing occurred
   precisely at at 22:19:00 local time – a duration just 0.7 seconds.

   Each of the colors on the Moon’s surface represents a class of
   minerals. For instance, blue areas are rich in  titanium, while
   orange areas are titanium poor. A common lunar mineral,  ilmenite,
   is rich in titanium oxides. Regions abundant in titanium are of
   interest because lunar titanium is bound to  oxygen. Of course,
   oxygen is critical for not only providing future astronauts a source of
   air to breath but for use as an oxidizer for rocket engines. Photo
   taken on March 26, 2021. Note that the bottom photo shows a close up
   view of another transit occurring earlier in the year.

   Photo details: Sky-Watcher Star Adventurer mount (it has a lunar
   tracking mode available); Sky-Watcher Evostar 72ED (72/420mm); filter
   wheel with Baader LRGB filters set (for the transit UV/IR filter was
   used); Barlow 2x lens; ZWO ASI174MM camera. The ISS image was cropped
   out and was stacked separately to improve clarity and sharpness.
