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.

Hi everybody, I organized the #Artemis2 photos for you. Index pages containing all ~10,000 images in chronological order with time stamps and focal lengths, color coded by which of three cameras was used to shoot them. countlessworlds.com/data/artemis/

Great interview with Steve Squyres on the Blue Origin podcast. Its been too long since I last heard him talk! First five minutes are on MER and oh man does that bring back the memories! youtu.be/cJS9F5mRnFk...

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.

Rock off. 🤘

Collected on April 23, 2026, by one of Vantor's WorldView Legion satellites, this image of the Hubble Space Telescope from above was acquired from only 61.8 km away.

Beautiful pics of the Artemis II astronauts, captured when they arrived on the flight deck of USS John P. Murtha, after returning from space (1/3) Photos by Petty Officer 2nd Class August Clawson, Explosive Ordnance Disposal Group One www.dvidshub.net/image/960862... #Artemis 🧪🔭

Love this! One of the best pictures from the whole mission!

It's April 12 here in Australia, which means it's Yuri's Night or the International Day of Human Spaceflight! 🧪

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...

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

Um OKAY. Breathtaking photos from the Artemis II crew's lunar flyby and eclipse viewing

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. 🧪🔭🚀🌘

Home. Earth, but in my case, that particular bit down there. #ArtemisII #Australia

Oh hey this is my article

London's BT Tower silhouetted against the disk of the rising Sun, with the sunspot groups of active regions AR13720 & 13719 prominent. 2024 June 25.

Too faint for the naked eye, but on the phone camera, #AuroraAustralis is clearly visible from #Melbourne (40°S).

This is what it would look like to fly over the Martian North Pole aboard @esa.int's Mars Express orbiter. This sequence of 117 images was captured by the VMC camera on June 14th, 2019 over the course of 3 hours and is played a 1200x speed. #planetsci Credit: ESA/Simeon Schmauß flic.kr/p/2rQAPdw

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.

Dr. Jane Goodall filmed an interview with Netflix in March 2025 that she understood would only be released after her death.

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....

Of course Earth is my favorite planet. It's home. But Mars is where my imagination lives. I've dedicated the last 8 years of my career to its exploration. I refuse to let billionaires ruin the home of my imagination and defile the frontier of the human experience.

Everyone is dealing with the US Presidential inauguration in their own way. My version, for now, is to express my thoughts as a citizen of the USA. Feel free to ignore this deeply political post, but as they say, “buckle up” if you choose to read through. 🧵

Managed to catch Comet ATLAS fortuitously through the only tiny gap in-between trees as seen from my balcony here in Melbourne. Pretty ancient Nikon D90, f/5 4”. 21:37 AEDT (58 mins past sunset) 6° above horizon, just about to enter cloud. #comet #cometc2024g3

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.
