On a dark background, the Moon nearly covers the Sun, leaving only a bright crescent visible on the left-hand side. The Sun's surface looks active, with bright yellow glowing loops sticking out from it. The Sun emits a yellow-orange glow that extends around the dark Moon, and faintly lights up the Moon's left side. Craters are faintly visible on the Moon's surface.

Update: So far there are no confirmed observations of the rocket stage hitting the Moon, but one possible detection of the impact plume from Paranal Observatory in Chile. 🧪 www.bbc.com/news/live/cr...

SpaceX rocket expected to have crashed into Moon - live updates

The stray upper stage (section) of the Falcon 9 rocket is about the size of a five-storey building, with a mass of at least 4,000kg.

At 2:35am EDT tonight, a Falcon 9 rocket upper stage will hit the Moon. The impact will occur just over the lunar limb, out of sight from Earth, but there's a chance the debris plume will be visible. We should be able to image the crater later. 🔭🧪 www.projectpluto.com/25010d.htm#v...

The impact point will be at lunar latitude 19.461 N, longitude 266.707 E = 93.293 W. The image shows how it'll look from the earth, with the impact at the blue circle-and-cross symbol. Somewhere close to that place and time, anyway; some parts of the motion of this object aren't entirely predictable. It will be close to the edge ("limb") of the moon as seen from earth, on the sunlit part. The moon will be a little more than half illuminated at the time.

Okay, wild thought: a SpaceX rocket will slam into the moon at 5,436 mph in 2026. That's like driving a truck from NYC to LA in 30 minutes! Wonder what kind of new geology that creates. Still, Earth's got even crazier natural forces.

A SpaceX rocket will hit the moon at 5,000 mph tonight. Experts explain what you could see, and when

A spent upper stage of a SpaceX Falcon 9 rocket is projected to crash into the moon early on August 5, 2026. This impact, occurring near the moon's Einstein crater, could be visible from Earth through

The rest of your natural life—and then some. That's how long we'll be cleaning up the mess of Trump and MAGAism. The nation as it was before is lost. It won't return. What we seek to save now isn't what used to be. It'll be something else altogether. It'll be what we make it.

As of this evening, The Odyssey has earned $911M in just 16 days. It will more than likely break the record for the fastest R-Rated movie to earn a billion, set by Deadpool & Wolverine in 2024 (23 days). They're calling it the most successful flop in history.

ZRVTO - Zero Relative Velocity Transfer Orbit. Shown here is a ZRVTO between Phobos and Deimos elevators. Phobos and Deimos could exchange payloads with practically zero propellant. It's possible between any two anchor masses in coplanar orbits.

For those interested in learning about the SpaceX rocket stage that will hit the Moon in a few days, this link has lots of good info and it delves into the speed of the object, where it will impact, if we will see the impact/plume, etc. Also includes resources for further reading.

Great thread once again by @doctorow.pluralistic.net. The whole thing is nuts. Snake oil salesman have played a blinder.

Neoclassical econ assumes rationality. The corollary of, "If you're so smart, why aren't you rich?" is "you're rich, so you must be very smart!" Thus, people assume that if powerful, well-compensated CEOs insist that "AI is changing everything," well then, *AI must be changing everything*. 1/

The Problem at the Heart of the AI Industry That Could Cause the Whole Thing to Collapse. Yann LeCun, one of the so-called godfathers of AI, has been warning that LLMs are a “dead end” and won’t bring us to the much-touted point where AI intelligence matches or exceeds that of human intelligence.

There's a Gigantic Problem at the Heart of the AI Industry That Could Cause the Whole Thing to Collapse

The AI industry has an enormous inefficiency problem, which doesn't bode well, considering how much money is being spent.

NASA & Katalyst Space are attempting to rescue the Neil Gehrels Swift Observatory, a powerful gamma-ray telescope that's on a death-spiral toward Earth. A booster spacecraft, called Link, is now on its way. It will attempt to grab Swift & lift it to safety. 🧪🔭 spacenews.com/pegasus-laun...
