This week’s image comes from the High Resolution Imaging Science Experiment (HiRISE) onboard the Mars Reconnaissance Orbiter. You don’t need to look too hard to see a bear in this photo.
Here is a summary of what you are seeing from the Lunar and Planetary Laboratory at the University of Arizona, which operates HiRISE:
There’s a hill with a V-shaped collapse structure (the nose), two craters (the eyes), and a circular fracture pattern (the head). The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?

In an earlier post, I noted the amount of poop as well as other trash left behind on the Moon from prior lunar missions. Well, Cagri Kilic, a Postdoctoral Research Fellow at West Virginia University, also ventured a guess at the amount of human trash that has already accummulated on the surface of Mars.
When you add up the mass of all spacecraft that have ever been sent to Mars, you get about 22,000 pounds (9979 kilograms). Subtract the weight of the currently operational craft on the surface – 6,306 pounds (2,860 kilograms) – and you are left with 15,694 pounds (7,119 kilograms) of human debris on Mars.
That’s a fair amount of trash and defunct equipment. And we are still adding to this toll, with plans to eventually send humans and material for settlements to the Red Planet. The same goes for the Moon, with multiple bases planned by the US, China, and Russia.
I expect we will see some other estimates in the future on what has been left on other planets, moons, and asteroids. And let’s not forget the five spacecraft we have shot beyond Pluto.
We humans do tend to leave a mess where ever we go. We may be explorers, but Boy Scouts would take issue given their principle “Leave No Trace.”
Former astronaut Walter Cunningham, who flew into space on Apollo 7, the first flight with crew in NASA’s Apollo Program, died early Tuesday morning in Houston. He was 90 years old. “Walt Cunningham was a fighter pilot, physicist, and an entrepreneur – but, above all, he was an explorer. On Apollo 7, the first launch of a crewed Apollo mission, Walt and his crewmates made history, paving the way for the Artemis Generation we see today,” said NASA Administrator Bill Nelson. “NASA will always remember his contributions to our nation’s space program and sends our condolences to the Cunningham family.”
NASA’s Curiosity rover has discovered opal on Mars. The deposits may prove to be valuable to future Martian explorers not as jewelry but as a potential source of water. Opal is formed when water weathers silica-rich rocks, forming a solution that settles into cracks and crevices in the rock. Over time, this solution hardens into a solid lump that can be cloudy and dull or a dazzling display of color. Most supplies come from either Australia or Ethiopia, but now a new source has been discovered – Mars.
NASA’s Juno probe is continuing to recover its memory at Jupiter after a data disruption interrupted communications between the spacecraft and its operators on Earth following a flyby of the giant planet in December. The Juno spacecraft’s latest flyby of Jupiter, its 47th close pass of the planet, was completed on Dec. 14. But as its operators at NASA’s Jet Propulsion Laboratory were receiving science data from the flyby they found they could no longer directly access the spacecraft’s memory.The team successfully rebooted Juno’s computer and on Dec. 17 they placed the spacecraft into “safe mode” with only essential systems operating as a precaution.
Both Andy Weir (author of The Martian, Artemis, and Project Hail Mary) and Rob Manning (Chief Engineer at the Jet Propulsion Laboratory) were shooting the you-know-what as they chatted about science fiction books they read as teenagers, the role of real science in fictional tales, astronomical conspiracy theories, and mankind’s need to expand into the unknown.
It was interesting to hear Andy Weir talk about curiosity being humanity’s survival mechanism. He pointed out that curiosity has allowed humanity to survive disasters here on Earth because we were all spread out rather than clustered on one flood plain. The same applies to expansion beyond the Earth.

The Mars Society is looking for volunteers who want to experience what it would be like to live on Mars. Don’t worry, you do not need to spend months traveling to get there, but you can experience the cold and isolation of the Red Planet while never leaving the Blue Planet.
The Mars Society is looking for six volunteers who will help to reactivate its Flashline Mars Arctic Research Station (FMARS), which is located on Devon Island in the Canadian Arctic and has not operated since 2017. This location creates a Mars-like environment that can be used to anticipate some of the issues future astronauts will experience on Mars.
What will you do? The site notes:
The team will spend the first half of this period working to repair and upgrade the station. It will then spend the second half of the visit exercising the station with a Mars mission simulation during which it will attempt to conduct a program of sustained geological and microbiological exploration while operating under Mars mission constraints.
The mission will take place from June through August 2023, so you do not have a lot of time to get prepared. It will be challenging work. Not only will you face aggressive Martians (in this case local bears), but you will have to assist with the financing of the mission. Each of the six volunteers will need to arrive with $20,000 in sponsorship funding. That said, you will not need to bring your own sleeping bag, as “…all supplies, mission equipment, training, firearms, transportation to the Arctic and transportation and housing while on site.”
Interested? You can read more about it here and reach out to the Mars Society at arctic-mission@marssociety.org.
The Mars Society also runs the Mars Desert Research Station in Utah. The site runs an eight month field season for professional scientists, engineers, and college students of all levels that trains participants for human activities on Mars.
