08/12/2019 – Ephemeris – Apollo 8’s giant leap to the Moon

August 12, 2019 Comments off

Ephemeris for Monday, August 12th. Today the Sun will be up for 14 hours and 12 minutes, setting at 8:53, and it will rise tomorrow at 6:42. The Moon, 3 days before full, will set at 4:38 tomorrow morning. | On the road to the Apollo 11 landing on the Moon 50 years ago was Apollo 8’s Christmas orbiting of the Moon in 1968. Apollo 7’s shakedown of the Command and service modules in October that year meant that they had a good spacecraft. However on September 28th that year a US spy satellite photographed a giant rocket of approximately the same size as the Saturn V on a launch pad at the Tyuratam Missile Test Center in the Soviet Union. Were they going to get to the Moon before us? Also Grumman was behind schedule with producing the Lunar Module for Apollo 8’s scheduled shakedown of that module in Earth orbit. NASA then decided to send Apollo 8 to the Moon instead and not miss a launch opportunity.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
