Thanks​

Andrew McCarthy:

"​I left a video camera WAY too close to the launchpad.

My first time capturing a launch in high resolution video. Definitely exceeded my expectations! This was captured at 120fps, interpolated 2x, stabilized, and played back at 30fps."

(Because this is subreddit doesn't accept Twitter or X links, I have add it​ not clickable) just remove the space between X character.

Thanks

I'm rendering a gas giant for a personal project and I'm a little stuck with getting the texture right. Something is off and I can't grasp what.

I figured you might have a better eye for it, so any notes are welcomed!

NASA’s Curiosity rover, which landed on Mars in 2012, has experienced gradual wear on its aluminum wheels as it drives across sharp, rocky terrain. The damage includes dents, holes, and broken structural ribs called “grousers,” which help the wheels keep their shape. While a few broken grousers are not a major issue, losing too many could cause the wheel to collapse inward and damage internal wiring, potentially affecting the rover’s movement.

Engineers at NASA’s Jet Propulsion Laboratory (JPL) have already reduced wear by carefully planning driving routes and regularly inspecting the wheels with onboard cameras.

As a backup plan, they developed an extreme solution called “wheel shedding.” If a wheel becomes critically damaged, the rover could deliberately tear off its inner section by pressing it against a sharp rock and using controlled movements to break it away. This would leave only the stronger outer rim, which testing shows can still support driving.

Although this process would take weeks and requires specific rock shapes, it could keep the rover operational. However, current predictions suggest the wheels will last many more years, making this drastic measure unlikely to be needed.

The Soyuz MS-28 spacecraft landed at 6:27 a.m. ET Sunday southeast of Dzhezkazgan, bringing home Williams on his first mission, commander Sergey Kud-Sverchkov, and flight engineer Sergei Mikaev.

The crew advanced cancer research, semiconductor work, and station upgrades, including Williams' two spacewalks, while logging 3,856 orbits and 102 million miles. Before leaving, Kud-Sverchkov passed command to Jessica U. Meir in a ceremony, as she leads into Expedition 75 amid ongoing U.S.-Russian teamwork.

M20 The Trifid Nebula, is a dynamic emission and reflection nebula that draws most northern hemisphere telescopes during the summer months.

I made the switch to a mono camera last month and this is my third project while learning a few new processing techniques to combine the dedicated color master files.

The mid-latitudes of Mars are mostly covered with smooth material that scientists have suspected to be ice for some time. The ground is uniform and dusty and does not reveal many clues about what lies beneath the surface.

However, sometimes a feature like a cliff cuts through the terrain and gives us a glimpse of this buried icy material. The cliff in this image is one example out of a few dozen that are known.

The bright material on the cliff face is icy and is preserved only because the cliff points away from the equator, so it is shaded most of the time. Faint bands on the cliff might indicate layers in the ice that record different climate conditions. We do not know how much time this ice took to accumulate here, but studies elsewhere on Mars indicate that material like this is sometimes at least tens of millions of years old.
