06/13/2019 – Ephemeris – Project Mercury

June 13, 2019

Ephemeris for Thursday, June 13th. Today the Sun will be up for 15 hours and 32 minutes, setting at 9:29, and it will rise tomorrow at 5:56. The Moon, 3 days past first quarter, will set at 4:23 tomorrow morning.

Celebrating the 50th anniversary of the Apollo 11 landing on the Moon we’ll look at the first human space mission program, Mercury. It was taken over from the Air Force by the newly organized NASA space agency in 1958. It’s mission to launch a man in orbit, having him survive for at least a day and return him to the Earth. Alan Shepard crewed the first Mercury launch on a suborbital hop on May 5th, 1961, 25 days after the Soviet Union launched Yuri Gagarin on a single orbit of the Earth. On the third Mercury Launch John Glenn was the first American to orbit the Earth in his Friendship 7 capsule. In all there were 6 flights in the Mercury program. Of the seven Mercury astronauts, only Deke Slayton never flew on Mercury for medical reasons buy flew in the Apollo-Soyuz Test Project in 1975.

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