Each April, during the week of the new moon,
International Dark Sky (IDS) Week invites people to reclaim the experience of wonder
Timed for the darkest nights of the lunar cycle, the observance encourages individuals and communities to turn off unnecessary lighting and reconnect with the stars.
What began as a small grassroots effort has grown into a global movement with profound ecological, cultural, and spiritual implications.
The event traces its origins to 2003, …
Assuming we can generate rocket fuel up there, I think it makes sense to use the moon to launch missions deeper into the solar system.

I think the bigger story here is that we didn’t notice a meteor narrowly missing Earth.
In a rare event, the moon got a massive new crater https://ground.news/article/in-a-rare-event-the-moon-got-a-massive-new-crater
Rob Navias: "From the pages of Jules Verne to a modern day mission to the moon, a new chapter of exploration of our celestial neighbour is complete. This mission is over but the melody lingers on."

NASA is building a nuclear reactor for the Moon by 2030 — and testing the nuclear propulsion that could carry humans to Mars in the decade after — under a new directive that revives a space-nuclear ambition the agency has been quietly chasing since Apollo

Oh the Americans want to increase their war budget by a few bucks, just a mere increase of ~40 percent. Germany also proudly moved to the top 5 of #military spenders worldwide. But money’s scarce y’all.
Can we have a moonshot beyond virtually shooting at the moon or burying souls for #AI assets?…

The Artemis II moon mission is one of the first times NASA has let astronauts fly with smartphones, giving them modified iPhones for taking photos and videos (Kalley Huang/New York Times)

As the Artemis II mission heads for a flyby of the moon,
the Orion crew module is testing one of NASA’s most ambitious upgrades to space communications yet:
a laser-based system called O2O.
Short for Orion Artemis II Optical Communications System,
O2O caps more than two decades of work by NASA and the Massachusetts Institute of Technology Lincoln Laboratory
to build better high-bandwidth links for deep space.
The system is designed to send data down to …
The SMC Blind Spot: A Failure Mode Analysis of State-of-the-Art Beat Tracking
Jaehoon Ahn, Tae Gum Hwang, Moon-Ryul Jung
https://arxiv.org/abs/2605.12287 https://arxiv.org/pdf/2605.12287 https://arxiv.org/html/2605.12287
arXiv:2605.12287v1 Announce Type: new
Abstract: Over the past two decades, the task of musical beat tracking has transitioned from heuristic onset detection algorithms to highly capable deep neural networks (DNN). Although DNN-based beat tracking models achieve near-perfect performance on mainstream, percussive datasets, the SMC dataset has stubbornly yielded low F-measure scores. By testing how well state-of-the-art models detect beats on individual tracks in the SMC dataset, we identify three distinct failure modes: octave errors, continuity errors, and complete tracking failure where all metrics fall below 0.3. We reveal that state-of-the-art models tend to generate "confident-but-wrong" activations. Furthermore, we show that the standard DBN's default minimum tempo of 55 BPM prevents it from inferring the correct tempo for 21\% of SMC tracks, forcing double-tempo predictions on slow music. By exposing such fundamental oversights, we provide concrete directions for improving beat and downbeat detection, specifically emphasizing training data diversification and multi-hypothesis tempo estimation.

More #MareOrientale in this new #ArtemisII #Moon image - https://www.flickr.com/photos/nasa2explore/55190158269/in/album-72177720307234654 - than in the first one with a long focal length presented. The lunar flyby webcast https://www.youtube.com/watch?v=z-j1uxBmis0 will begin at 17:00 UTC today and the lunar observations run from 18:45 UTC to 1:20 UTC on 7 April - as explained in the press conference tonight we will mostly get images from the exterior cameras with astronaut commentary of what they see; real photographs like this one will be downloaded later during the day and the following ones.
Artemis II reminded me what spaceflight used to feel like—uncertain, human, and a little terrifying.
Not just “cool.” Something more. 🚀

The Moment Spaceflight Felt New Again
Watching Artemis II launch stirred something deeper than excitement—something human. After decades of routine spaceflight, this mission reminded me what it feels like to hold your breath, hope, and believe again.
