All I planned was a Sol 5000 morning postcard......credit to Kevin for adding the PM poscard on 5003 and doing the processing on this one.

The rover was ~120 m shy of a marathon at this location. If you follow the dark streak heading southwest, you’ll see two ‘fresh’ craters of equal size. The ‘finishing line’ was just above them.

After exploring the surface of Mars for 20 years maybe you think we've seen it all? Lol, definitely not. This morning's view from Curiosity is WILD.

Cloudy Mars: Olympus and Tharsis, ESA Mars Express HRSC Massive 220MP image on Flickr ➡️ flic.kr/p/2seL8ss 🔭🧪 Credit: ESA/DLR/FUBerlin/AndreaLuck CC BY 2025-08-02 North is down HR242_0000 ND3+GR3+BL3 Notes: Cool cloud formation over the North Pole and a dust storm-like feature over Olympus Mons!
View of Mars from orbit. Colours are rusty red and pale white from cloud cover and atmospheric haze. Bright white polar ice caps swirl near the top, while thin cloudy streaks drift across the surface. Four large circular volcanoes are arranged in a broad triangle across the planet’s face. The scene feels dry, vast and softly hazy. Notably, a very cool spiral-like cloud formation appears over the North Pole, along with a dust storm-like feature near Olympus Mons.

It's April 12 here in Australia, which means it's Yuri's Night or the International Day of Human Spaceflight! 🧪
un.org
International Day of Human Space Flight | United Nations
12 April 1961 was the date of the first human space flight, carried out by Yuri Gagarin, a Soviet citizen. This historic event opened the way for space exploration for the benefit of all humanity.

Fun fact: many of the prettiest photos taken by robotic spacecraft were similarly framed ahead of time by humans using simulators of view geometry to pick when the spacecraft should shoot the photo. Case in point: this photo of Europa over Jupiter from New Horizons science.nasa.gov/image-detail...
New Horizons Spies Europa
NASA's New Horizons spacecraft took this image of Europa hanging above Jupiter's cloud tops with its Long Range Reconnaissance Imager (LORRI) at 11:48 Universal Time on February 28, 2007, six hours after the spacecraft's closest approach to Jupiter. The picture was one of a handful of the Jupiter system that New Horizons took primarily for artistic, rather than scientific, value. This particular scene was suggested by space enthusiast Richard Hendricks of Austin, Texas, in response to an Internet request by New Horizons scientists for evocative, artistic imaging opportunities at Jupiter. The spacecraft was 2.3 million kilometers (1.4 million miles) from Jupiter and 3 million kilometers (1.8 million miles) from Europa when the picture was taken. Europa's diameter is 3,120 kilometers (1,939 miles). The image is centered on Europa coordinates 5 degrees south, 6 degrees west. In keeping with its artistic intent - and to provide a more dramatic perspective - the image has been rotated so south is at the top.

A bit of a different take on the amazing Artemis II launch footage. Here I stitched clips from the four Solar Array Wing Cameras to make this panoramic video. This is during the later part of the Core Stage burn until MECO and stage separation, sped up to 10x. 🔭🧪 #Artemis

Look, I know I am biased, but the #ArtemisII crew don't talk about wastewater dumps with unbridled joy. They don't do suit tests with a grin that will break their face in half. Our human space flight serves many purposes, but SCIENCE is undoubtedly the shiniest. 🧪🔭🚀🌘

Too faint for the naked eye, but on the phone camera, #AuroraAustralis is clearly visible from #Melbourne (40°S).
Purple pillars of Aurora light embedded in more diffuse purple with green through the silhouetted trees closer to the horizon. Many stars are visible, including the Southern Cross.

Kudos to our project scientist who helps advocate for these every ~year when I think the view might work and we've got a little bit of energy and time spare in a plan. Doing the science on the day to day is important. Taking a moment now and again to do something just for art is important as well.

The MER rover Opportunity photographed the lengthening shadows on its 2847th Martian day, or 'Sol'. I combined 6 images making this view while fighting the wildly different contrast and exposures in the preliminary jpegs. Two versions are on the ASU PANCAM site: pancam.sese.asu.edu/2847B_P2445....
The MER rovers brought us a great variety of views of Martian scenery. This mosaic of 6 frames show the shadows lengthening across the interior of 14 mile (22 km) wide Endeavour Crater. This is the initial 'Monument Valley red' version I made, later I reconsidered what the colors should be and both versions appear at the Arizona State University of Arizona PANCAM page. This image was picked up all over the place, and appeared on the cover of the Summer Solstice 2013  issue of the Planetary Report.

Today I finally got to meet Glen Nagle in person after nearly 20 years of knowing each other online! He gave us an amazing tour of Canberra DSN complex. The amount of space history artefacts that Glen has been able to save, both in the visitor centre and in his archive is staggering.
