For the curious - Artemis II has a total of 28 camera systems, many for internal and external inspection and navigation.
Engineering cameras, located on each of Orion’s 4 solar arrays: GoPro HERO4 Black 12 MP
Handhelds: Nikon D5 digital SLR 20.8 MP
These were selected many years ago.

From NASA: Eclipsed: A View from Orion art002e009571 (April 6, 2026) - The Moon, backlit by the Sun during a solar eclipse, is photographed by NASA’s Orion spacecraft on April 6, 2026, during the Artemis II mission. Orion is visible in the foreground on the left. Earth is reflecting sunlight at the left edge of the Moon, which is slightly brighter than the rest of the disk. The bright spot visible just below the Moon’s bottom right edge is Saturn. Beyond that, the bright spot at the right edge of the image is Mars.

The lunar surface fills the frame in sharp detail, as seen during the Artemis II lunar flyby, while a distant Earth sets in the background. This image was captured at 6:41 p.m. EDT, on April 6, 2026, just three minutes before the Orion spacecraft and its crew went behind the Moon and lost contact with Earth for 40 minutes before emerging on the other side. The dark portion of Earth is experiencing nighttime, while on its day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater shows terraced edges and a relatively flat floor marked by central peaks — formed when the surface rebounded upward during the impact that created the crater.

Don't forget that this mission isn't just about science. It contributes to carving the Moon up between nations and corporations to exploit its resources. #PlanetSci #ArtemisII

Nice piece by @hannah-richter.bsky.social on @science.org news on the NASA plans to build a nuclear propulsion Mars mission in under 3 years.

Besides many challenges, there is a small, but not zero change that a new sat doesn't make it and re-enters. What then? 🔬🔭 #planetsci

Aaaaaand the pendulum swings!
With Artemis II half way to the moon, Trump proposes a 23% cut to NASA to fund his new war economy. The ink on the NASA bills and Isaacman's statements isn't even dry! 🧪🔭 #planetsci

New story with details about the ‘SR-1 Freedom’ nuclear propulsion mission to Mars. How would it work, and where did the idea come from? Is there any chance of meeting the timeline?

It was pretty indescribable to actually watch a rocket carrying humans launch to the Moon in person. It’s not hyperbole for me to say that for my entire life I have hoped that I would actually see this happen. #PlanetSci #Artemis2

As the Artemis II mission prepares to go round the Moon, it's a good time to remember that people have been thinking about how to ensure the Moon has the right to its own ecological integrity. 🧪 #PlanetSci

Ever wonder where the science landed on bio-signatures on exoplanets? Our @oxfordphysics.bsky.social colleague @astrojake.bsky.social has written up a succinct summary of the drama and what the latest paper adds.
It's a good read!

The Dec 2028 timeline for an entirely new mission, using untried technology, seems completely implausible. It appears to be driven by the end of Trump's presidential term, not science or engineering. 🧪🔭🛰️ #planetsci
The quotes in the NASA press release are eye opening.

NASA's new leadership has plans:
- A nuclear propulsion spacecraft (a technology that has never been implemented) delivering multiple helicopters to Mars in 2028.
- A surface base on the Moon (no orbiting Gateway), and expanded commercial launches.

Skyfall is happening, and it will get to Mars in a totally new way.
Last summer, NASA's Jet Propulsion Laboratory and the Virginia company AeroVironment unveiled their Skyfall mission concept, which would send a fleet of tiny helicopters to explore the skies of Mars. 🧪 #PlanetSci

Things are moving quickly and taking shape. The ugly part is said aloud: gateway is paused. But the moon base will go fast!

Looking for an updated list of the number of moons in our solar system. My usual reference is missing the recent additions from Jupiter, and while Wikipedia seems up-to-date, I’d prefer a verified scientific source to share with students. Thanks in advance for feedback! #planetsci #astro

This image features the tiny moon S/2025 U1 (circled) and 13 of the 28 other known moons orbiting the planet Uranus. Due to the drastic differences in brightness levels, the image is a composite of three different treatments of the data, showing details about the planetary atmosphere, the surrounding rings and the orbiting moons. The Uranian system, appearing in shades of very light turquoise for the planet's globe and light turquoise for the rings, stands out sharply against the black background of the image.

Update March 2026: In August 2025, the discovery of a faint new moon around #Uranus, was announced.
That pushed the known count of its moons to 29.

Editor's choice: the search for life on Mars must avoid contamination by life transported from Earth. Bischof et al. investigate the micro-organisms on and within spacecraft that landed on Mars. How long can they survive on the red planet? 🧪☄️🔭 #planetsci
