Artemis II – WDR 2
Posted by jpluimers on 2026/02/20
Edit 20260221: the below WDR 2 link has been renamed into [Wayback/Archive] Artemis II – Launch with Launch T0: 2026-03-07 01:29:00 UTC (yup, that T0 is T-zero, not T-oh) which the Americans date as 206-03-06 as they use local EST time which is only valid at their east coast.
Artemis II testing and launch videos, including timeline, can be viewed from [Wayback/Archive] Artemis II – WDR 2.
Yesterday, as part of the launch vehicle system tests, the second wet dress rehearsal was performed.
Somewhere the next few weeks, a launch is anticipated.

I think I like the transparent version most, but the wood versions (yellow or brown) of course have more mystery.
There are more products in [Wayback/Archive] Wooden Kinetic Sculpture for Art Lovers – LovelyWings.
You can buy some of them at [Wayback/Archive] Amazon.com: LovelyWings, for instance the brown version of the [Wayback/Archive] Amazon.com: Perpetual Motion Machine – Infinitive Marble Machine – William Le’s Perpetual Motion Simulator : Handmade Products.
