Ephemeris: 04/11/2025 – Thoughts on Starliner and Artemis problems
This is Ephemeris for Friday, April 11th. Today the Sun will be up for 13 hours and 18 minutes, setting at 8:23, and it will rise tomorrow at 7:03. The Moon, 1 day before full, will set at 6:44 tomorrow morning.
As someone who has watched the Apollo program progress, back in the 1960s, and the race to get to the Moon before the Russkies, the Artemis program seems rather sluggish. Most of the reason of course, is because it isn’t enough of a high priority, and we’re trying to do it on the cheap, reusing as much of the ill-fated space shuttle hardware as possible. NASA is gun shy about putting astronauts into danger, when they don’t have to. The Apollo 1, and two Space Shuttle accidents is the main reason that Butch and Suni didn’t ride back to Earth in their ailing Starliner capsule. The Starliner capsule is built by the same company, Boeing, who is prime contractor on the main stage of the moon rocket. Both have experienced long delays, and quality issues.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). Times will be different for other locations.

Ephemeris: 08/27/2024 – Space news
Sorry, about posting this late. I was working on our astronomical society article and newsletter. The article will be posted as an Ephemeris Extra in a couple of weeks. For a preview see my August 22nd post.
This is Ephemeris for Tuesday, August 27th. Today the Sun will be up for 13 hours and 27 minutes, setting at 8:27, and it will rise tomorrow at 7:01. The Moon, 1 day past last quarter, will rise at 12:55 tomorrow morning.
Let’s take a look at some space news. Today is the first day of the launch window for the SpaceX commercial mission Polaris Dawn where 4 private astronauts will ride a SpaceX Dragon capsule to the highest point astronauts have been since the Apollo days, some 1400 kilometers or 870 miles above the Earth. They will also perform the first commercial EVA or space walk. Two of the astronauts will take turns poking their body out the hatch capsule for a short period of time. They will not be free floating, but they will be connected to the capsule by foot or hand restraints.
In other news NASA has decided to bring Suni Williams and Butch Wilmore, the Boeing Starliner test astronauts, back to Earth on a Dragon capsule in February due to safety concerns.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT–4 hours). Times will be different for other locations.

12/30/2019 – Ephemeris – Some space advances this year
Ephemeris for Monday, December 30th. Today the Sun will be up for 8 hours and 50 minutes, setting at 5:10, and it will rise tomorrow at 8:20. The Moon, 3 days before first quarter, will set at 9:45 this evening.
Let’s look back at space activity this past year. SpaceX launched its Falcon Heavy rocket twice successfully for commercial payloads. It also performed the Demo 1 flight to send a uncrewed Dragon 2 to the International Space Station. That went off without a hitch. However when testing the same capsule a month later it was destroyed in a fueling mishap that postponed further flight tests until next month. The other Commercial Crew contractor Boeing was having problems with its Star Liner capsule. The latest being a mishap with their test flight to dock with the ISS. Supposedly a timing malfunction caused it to use too much fuel, so it ended in the wrong orbit. However it did land safely.
The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
