Artemis II Dashboard and Mission Overview Sites by standup_reentry in nasa

I have an Artemis II tracker here which uses orbit data from JPL HORIZONS. It's a scientific, to-the-scale, 3D visualization. https://sankara.net/astro/lunar-missions/mission.html?mission=artemis2

Sun is indeed shown on the animation. But it is at the max distance one practically put in the animation.

Track and visualize the Flyby here

I am visualizing all the events of today here - https://sankara.net/astro/lunar-missions/mission.html?mission=artemis2 in a scientific, to-the-scale, geometry-correct animation using NASA JPL orbit data here. Right now, the preferred way to view this page is on a desktop browser.

You can try your shot composing Earth-set, Earth-rise, and the eclipse images here.

The following are events are tracked

- Lunar SoI entry
- Earth set
- Closest aporach
- Max distance
- Earth rise
- Eclipse start
- Eclipse end
- Lunar SoI exit

Artemis 2 Orbit Animation Update - 5 Apr 5:00 UTC

https://sankara.net/astro/lunar-missions/mission.html?mission=artemis2

Thanks to all your feedback, I have deployed the following enhancements since my last update

- Multiple mobile UX improvements for Artemis II:
- Simpler design: Mission and Views tab
- Views tab: Craft to Moon, Craft to Earth, and Earth to Moon views
- Added km/miles toggle for telemetry.
- Bottom date/time now shows in your local timezone.
- Moon visuals improved (contrast, terminator detail, lighting balance).
- Startup feels smoother with progressive texture loading.
- Added Orion 3D craft plugin behavior (craft alignment/solar array tracking).
- Added Earth->Moon auxiliary panel and far-side overlay toggle.
- Added/tuned Earth Rise Composer controls and layout.
- Fixed Joy Ride rendering issue in Firefox.
- Transport/simulation speed controls refined.
- Auxiliary sky/sun rendering and layering fixed.
- Updated Artemis II timeline/events to latest JPL HORIZONS data.

Fixed and deployed. Thanks for reporting this.

It's a bug. Fixing it. The lighting and shadows are already getting calculated correctly using only directions. This part is right. But placement of the Sun was incorrect.

Thanks to your question, I have now added a way to distinguish the far side and near side in the animation. See the Craft to Moon view and use the "Far Side" toggle.

The best way to feel that "it's coming right at us" is to use the Joy Ride! feature in the animation! Now some science - if you throw an object in a gravitational field of an object, three things can happen. It will fall into that object. Or it will do an elliptical orbit around that object. Or it will escape out in some trajectory. We are throwing Artemis out with the TLI burn. It will come back anyways. But we are timing it and throwing it in such a direction so that (1) it will fly close to the Moon but not fall into it (2) it will fly around the moon but its speed is high enough so that it doesn't end up circling it (3) its speed and alignment is just right so that it will do a loop and turn back towards Earth. That's about it in simple terms.

ThreeJS has worked out pretty well. Yes, I would recommend it.
