My goal is to make it easy for any astronomy club to call a quick public observing session to see the moving dot of the Artemis spacecraft. Obviously this depends on local weather and whether the spacecraft could be seen in the evening from a specific location. I think there's plenty of time before launch to set this up.
The spacecraft would have to be close enough to be seen. Here's my brightness estimate:
ISS 400 km overhead Mag ~ minus 5
Artemis at same height if 1/100 as bright Mag 0 (??)
Artemis at 4000 km Mag 5
Artemis at 40,000 km mag 10
Artemis at 400,000 km (Moon) mag 20
I've seen many mag 10 objects through my 4 inch refractor at a dark sky site. Larger scopes could see deeper, perhaps balancing light pollution.
If conditions are right, the public could see the spacecraft dot moving. Ideally show it on a monitor. Image the excitement of seeing a burn then a change in direction.
I'm looking for ways to make it easy to predict the location in the sky with up to the minute changing of orbit elements after a burn. This would have been more exciting for Apollo 8 or 11, but some might still want to see the first humans in a half century heading moonward. If a planetarium program made appropriate arrangements including prompt upgrading of data, then this outreach might be feasible. It could be called at the last minute and a club member could get a slot on a local radio program.
Perhaps some members of the public might get more turned on by astronomy.
Clear skies for 2026 everyone!
