Uncommon bright dot in today's Mars Perseverance Rover Navcam image on sol 1834. It's about the location of comet C/2025 R3 Panstarrs, but could be lens flare. 📷 ssd.jpl.nasa.gov/tools/sbdb_l... and areo.info/mars20/ecams...

I'm wondering why many NASA astronauts point out the blackness of space. Christine Koch at 58:47 in the video: It was all the blackness around it. Earth was just this lifeboat hanging undisturbed in the universe. [9s pause] Uh - Oh. [5s pause] ...

I really like the symbolism of this Artemis 2 splashdown photo taken by Josh Valcarcel with the sailboat in the close distance. Most likely inspired by one of the best documentary feature film scenes... 📹 watch.plex.tv/movie/kon-ti... , 📷 images.nasa.gov/details/DSC_...

If we are lucky, Artemis 2 atmospheric entry can be seen from the SEN 4K cameras on the ISS in this live stream in a few minutes: www.youtube.com/watch?v=fO9e...

The Artemis 2 solar eclipse photo is spectacular on its own, but it's not a total solar eclipse in the direct sense, not matching it perfectly like an eclipse is commonly expected to appear. Only during Gemini XII in 1966, a perfect eclipse was seen in space ever, by Buzz Aldrin and Jim Lovell.

That sunlight scattering particle cloud doesn't appear to be the zodiacal light dust near the Sun. Could be related to the Moon's sodium cloud and tail. Animation from 1999 research by Steven Smith and Jody Wilson at Boston University: sirius.bu.edu/moontail

Mare Orientale on the Moon, the science objective NASA chose to look at by the Artemis 2 crew, is located at the 19.5°S latitude, which is the very location of maximum volcanic or atmospheric activity on all planets in the solar system.

The spectacular Artemis 2 Earth image was acquired from about 10000km distance, position confirmed with NASA Eyes on the Solar System simulation: Venus is the bright dot. Exact time of image is visible in the EXIF data: April 3 00:27 UTC www.nasa.gov/gallery/jour... and eyes.nasa.gov/apps/solar-s...

The big beautiful orange rocket reached space and is on the way around the Earth for the next 24 hours, and then onwards around the Moon! The large 250 America stickers on the boosters were well visible as well as the red NASA "worm" logo.

A nuclear powered helicopter carrier to Mars! Using the 25 kW SR-1 Freedom fission reactor and delivering a swarm of Ingenuity-style scout helicopters. A real Sci-Fi like future, much improvement to slowly crouching artisan rovers. NASA Administrator Jared Isaacman today, 0:17:45 in the recording:

A few minutes ago, NASA Administrator Jared Isaacman announced Space Reactor-1 Freedom! That's a significant leap as it will literally boost spaceflight towards a new generation of spacecrafts. www.nasa.gov/news-release... Quote...

Thanks to Avi Loeb for reminding about comet C/2026 A1 (MAPS)! I noticed it will reach its extreme close Sun distance of less than a solar diameter on April 4, the night to Easter Sunday! Quite a cosmic easter egg when it really reaches brightness magnitude -5 next to the Sun during the day...

As readers have pointed out, whether the sol 1792 boulder is really granite, isn't sure yet. To add into the discussion I'll throw in this rock from sol 1644 which shows many large crystals and large granular structure, usually a sign of felsic intrusive rocks, granite is one classification of...

Asteroid Bennu samples show magnetic field strength remains as high as rocks on Earth: Up to 37 micro Tesla was measured in the samples, some even higher, which matches the range of Earth's magnetic field near the surface of 25 - 65 micro Tesla...

Prof. Avi Loeb team's finding of 3I/ATLAS' nucleus rotation and especially its rotation axis parallel alignment with the sun direction is a major discovery! One explanation for that alignment would be in my interpretation the (magnetic) field-aligned current at the comet in the anti-sun line...

No images yet today from Mars on President's Day which coincides with Mars day 1776 on the surface when counting landing day as 1. Usually with Perseverance Rover, landing day is counted as 0 so sol 1776 will be tomorrow, February 17. Images below from yesterday, more on areo.info/mars20

With comet C/2026 A1 MAPS the topic of sun-grazers made news, here some more details: This comet is part of the well known Kreutz Comet Stream, a trajectory with a constant rate of 1 new comet every 2 days either crashing into the Sun or being vaporized at close distance. Fewer than 0.1% of those...

Thanks to community help the mystery UAP in the NASA Artemis 1 2022 video near the Moon is identified and an even more interesting discovery was made! NASA considered the dot above the Moon to be Saturn (video caption). That it can't be Saturn I already found out a few months ago...

Lithified ripples have been observed to be East-West aligned over their ridges. 1963 paper by Johannes A. Dons from Norway where they are most common: Ripple marks and mud cracks.

Ripples on Mars and at Mt Nebo, AR. The classic interpretation would be suddenly hardened sand ripples in shallow water, but I doubt that. At Sunrise Point on the Mt Nebo 400m above the Arkansas River at 100m, it would be possible, but even there other strange things can be seen there.

If you enjoyed the timelapse above, I also made a full duration video of the Artemis 1 reentry with even more telemetry data overlayed. 🔭 www.youtube.com/watch?v=-QbY...

Interesting uniformly spaced distribution of small white rocks around the rover and a more on the hills.
