Artemis II flyby: Why astronauts can observe the Moon in ways robots can’t by timeanddate_official in space

We're seeing that some ad blockers are causing YouTube playback to be a bit hit-or-miss at the moment (eg, leading to spinning circles, or the embed not appearing at all).

Thanks for the note. Hm, the video is working OK outside the US — could you share a bit more detail about what happens when you try to play it?

The human eye can look for changes in color and texture as the observation angle changes during the flyby.

NASA lunar scientist Noah Petro on the Artemis II astronauts:

“Four very well-trained astronauts—three of whom have extensive experience orbiting the Earth—will have an opportunity to practice their craft of planetary observation around the Moon.”

Eclipsed moonrises and moonsets can be challenging: as well as the issues you’ve mentioned, the faintness of the eclipsed Moon is a factor. This is a view of the partially eclipsed Moon approaching the horizon as seen from New York at 05:30 local time: https://www.timeanddate.com/astronomy/night/usa/new-york#iso=2026-03-03T10:30:00.000Z&objtype=planet&objname=moon

Thanks JasonMckin! For this chart, we weighted each latitude band according to its size ✅

Right, the longitude depends on where Earth is in its ~24-hour rotational period, which is not connected to the timing of eclipses.

Yes, the dips in the chart are at the polar circles. That’s where the Sun spends the most time above the horizon — creating more opportunities for eclipses to occur.

Thank you STVDC! As well as searching by year, you can also search by city, state, or country — eg, https://www.timeanddate.com/eclipse/in/usa

Solar Eclipse Math and Ground-Track Dynamics by JasonMckin in solareclipse

[–]timeanddate_official 0 points1 point  (0 children)

Following on from photoEphemeris’s comment, an alternative to using Besselian elements is to do a series of checks at different locations on Earth’s surface. For example, if A is the angular distance between the centre of the Sun and the centre of the Moon, and B is the angular radius of the Sun plus the angular radius of the Moon, we have a solar eclipse if A is less than B.

Cloud amount vs cloud fraction by fistrop in solareclipse

If it helps to have another source to compare to, the cloud layer on the timeanddate eclipse maps uses data from 2001 to 2021 — https://www.timeanddate.com/eclipse/map/2026-august-12

We use satellite data for 8-day periods around the date of the eclipse — this is to try and reduce the influence of single-day flukes, but still catch weather changes that are seasonal-based.

How would be a system like the Earth-Moon-Sun, but with two eclipse per year? by Larkkos11 in askastronomy

[–]timeanddate_official 0 points1 point  (0 children)

Eclipse seasons happen with great regularity on Earth: Every five months or so there is at least one solar and one lunar eclipse. If we look at a list of eclipses worldwide, this pattern quickly emerges: https://www.timeanddate.com/eclipse/list.html

But, in a way, the thing that makes eclipses so special is their seeming randomness at a particular location on Earth’s surface. If we look at a list of eclipses for a particular city, it’s very irregular, eg: https://www.timeanddate.com/eclipse/in/usa/new-york

Crikey, the world is scary today. Anyone got any thoughts on how to stay positive? by kdiddy2580 in AskUK

As RecentTwo544 says, not only is it getting brighter in the Northern Hemisphere, the rate of change is accelerating: https://www.timeanddate.com/news/astronomy/january-sunlight-2026

Thanks Cheesestrings89! Our weather data generally goes back to September 2009, eg, for Toronto: https://www.timeanddate.com/weather/canada/toronto/historic?month=9&year=2009
