This is Ephemeris for Monday, August 31st. Today the Sun will be up for 13 hours and 15 minutes, setting at 8:20, and it will rise tomorrow at 7:05. The Moon, 2 days before full, will set at 6:10 tomorrow morning.

The Artemis program is the United States follow on, after more than 50 years, to return to the Moon. It’s main rocket, the Space Launch System or SLS uses components of the Space Shuttle that include the main engines, using 4 instead of three, and two longer solid boosters. The Orion capsule sits atop the second stage. Unlike Apollo, the lunar lander will be sent up on a separate rocket into lunar orbit. Eventually there will be a lunar orbiting space station called the Lunar Gateway as a way point. But not for the first attempt. NASA has accepted three bids for commercial landers, Dynetics with a squat lander with drop-tanks. The National team of several companies with an Apollo-like lander on steroids, and SpaceX’s Starship.

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