This vintage 60-kopek stamp celebrates a
dramatic achievement. On the 7th of October,
1959, the Soviet "Luna 3" successfully
photographed the far side of the moon giving
denizens of planet Earth their first ever view of
this hidden hemisphere. Lacking the digital image
technology familiar now, Luna 3 took the pictures
on 35mm film which was automatically developed on
board. The pictures were then scanned and the
signal transmitted to Earth days later in what
was perhaps also the first interplanetary fax. In
all, seventeen pictures were received providing
enough coverage and resolution to construct a far
side map and identify a few major features.
Depicted on the stamp are regions dubbed the Sea
of Moscow, the Soviet Mountains, the Bay of
Astronauts, and the Sea of Dreams.

Have you ever seen a halo around the Moon?
This fairly common sight occurs when high thin
clouds containing millions of tiny ice crystals
cover much of the sky. Each ice crystal acts like
a miniature lens. Because most of the crystals
have a similar elongated hexagonal shape, light
entering one crystal face and exiting through the
opposing face refracts 22 degrees, which
corresponds to the radius of the Moon Halo. A
similar Sun Halo may be visible during the day.
The picture was taken in Lansdowne, Pennsylvania,
USA. Exactly how ice-crystals form in clouds
remains under investigation.
