Moon & Mars Mondays · your week on the Moon and Mars

From The Decisional Pass

Last Monday I made a fuss about an eleven-year-old picture — a 2015 LRO frame of an unremarkable patch of ground near Einstein crater, taken for no reason except that mapping the Moon is what LRO does, which suddenly became the most valuable "before" image in the solar system when a Falcon 9 upper stage put a hole in it.

This week, on two earnings calls, the people who want to take the next eleven years of those pictures said out loud that NASA is about to go shopping.

The Moon needs a new camera

NASA plans to award three more lunar delivery missions under CLPS before the end of the year. Two are landers. The third is the interesting one: an "orbiter imaging service."

That phrasing is doing a lot of work. NASA is not proposing to build a spacecraft. It is proposing to buy pixels — the way it already buys rides to the surface — because the camera it has now is old.

LRO launched on June 18, 2009, on an Atlas V, with a one-year primary mapping mission. It is now in an extended mission approved through 2028. Its two narrow-angle cameras resolve about 0.5 metres per pixel across a 5-kilometre swath from a 50-kilometre orbit, and they have been doing that, consistently, for seventeen years. A 2022 assessment quoted by SpaceNews put it bluntly: a modern replacement is "long overdue."

Two CEOs said the quiet part on the record last week.

• Jason Kim of Firefly Aerospace, on the company's second-quarter earnings call, listed the orbiter imaging service among the three task orders he expects by year-end.
• Steve Altemus of Intuitive Machines, on his own call days later, described it as "the orbiter surveyor to map the moon in replacement of the Lunar Reconnaissance Orbiter," and said he expects it "later this summer or in early fall."

There is a small, delicious irony in that second quote: Intuitive Machines currently operates LRO's high-resolution camera under contract. The incumbent operator is bidding to replace the incumbent.

Firefly already has a product on the shelf for this. Ocula, announced in June 2025, puts Lawrence Livermore telescopes on Firefly's Elytra spacecraft in a 50-kilometre lunar orbit and advertises 0.2-metre resolution in ultraviolet and visible light. That is roughly two and a half times finer per pixel than LRO's narrow-angle cameras. It is funded to fly on Blue Ghost Mission 2 — the far-side mission, no earlier than late this year — and again on Blue Ghost 3 in 2028.

Here's the engineer's caveat, and it's the whole story.

Resolution is the easy part. What makes LRO irreplaceable is not that its pictures are sharp — it's that there are seventeen years of them, taken by the same instrument, calibrated the same way, archived in a form you can difference against. That's what turned a random 2015 frame into a measurement. A brand-new 20-centimetre camera is better than LRO's on day one and worse than LRO on every question that starts with "what changed?"

You cannot procure an archive. You can only start one, and then not stop. Which is exactly the thing a service contract, renewed or not renewed on a budget cycle, is structurally bad at.

Both of these companies are publicly traded now, which means you can watch this play out on a quarterly cadence — the public-company board is here.

Wrenches down, no ride

On August 11, NASA announced it had finished building LEMS — the Lunar Environment Monitoring Station — the first science payload completed for Artemis astronauts to carry out and set down by hand.

It is about the size of a small suitcase and weighs 11 pounds in lunar gravity. Inside are two seismometers that NASA calls the most compact, sensitive and energy-efficient ever built for planetary work. It runs off a lightweight flexible solar array, phones home about once a month, and is designed to sit there and listen for years.

The hard part was never the seismometer. It was the night.

A lunar night is fourteen Earth days long, and LEMS is qualified to survive temperatures down to −400 °F. Most surface hardware solves that with a radioisotope heater — a slug of plutonium quietly keeping the electronics above their minimum. LEMS doesn't have one. It survives on insulation, deliberately low-thermal-conductivity cabling, and passive thermal design. That is a genuinely hard problem solved with geometry and materials instead of a heat source, and it's the reason the thing can be described the way its project lead, Mehdi Benna of UMBC, described it: "a scientific buoy for the Moon."

The build is spread the way good instrument builds usually are — UMBC and Maryland leading the science, Goddard doing the engineering, the University of Arizona and Silicon Audio on the seismometers, Morehead State on the radio, Washington University in St. Louis on the data.

And it is finished, and it does not yet have an assigned Artemis mission.

I have complicated feelings about that. Hardware finished ahead of its ride is the most enviable problem in this business — everyone I know has lived the opposite. But "complete, awaiting manifest" is also the phrase on a lot of boxes that never flew. Batteries age. Seals age. Teams disperse. The clock does not stop just because the wrenches went down.

It matters because of what's missing. The Apollo seismic network — stations at the Apollo 12, 14, 15 and 16 sites — was commanded off on September 30, 1977. The Moon has not had a long-lived seismic network since. Forty-nine years of a body we intend to build on, and no one listening to it shake.

One week out at Wenchang

Which brings me to the part of this week's news that actually has a rocket underneath it.

China's Chang'e-7 is at Wenchang, and so is its Long March 5 — the rocket arrived at the launch site on July 13, the spacecraft back in April. Airspace notices point to a launch window opening at 00:00 UTC on August 24, with daily opportunities running through the end of the month.

Treat that date with the caution it deserves. CNSA does not publish launch dates in advance; this one is reverse-engineered from navigation warnings, and it is not official. But it is one week from today, and everything physical is where it needs to be.

The mission is four spacecraft — orbiter, lander, rover, and a hopping probe — carrying 18 science payloads, six of them contributed internationally — Egypt, Bahrain, Switzerland, Thailand, Italy and Russia are among the partners. The target is the rim of Shackleton crater: lit enough to run on solar power, close enough to reach into the permanent shadow next door.

The hopper is the piece I keep thinking about. It carries a water-molecule analyzer, and the concept of operations is to hop into a permanently shadowed crater floor — somewhere that has not seen sunlight in billions of years and sits at a few tens of kelvin above absolute zero — drill a sample, seal it, heat it, and read the vapour with a mass spectrometer. Every single one of those verbs is hard in that thermal environment. Sealing is the one I'd lose sleep over: you are trying to trap a volatile that wants to sublimate the instant you warm it, using a mechanism cold-soaked to a temperature where most lubricants are a solid.

And on the lander, among those 18 payloads, there is a seismograph.

So here is this week, in one sentence. NASA finished a seismometer and has nowhere to put it yet, and is drafting a contract to buy the Moon's next camera as a subscription. China intends to launch one toward the south pole in seven days.

None of that is a verdict about who's ahead. It's a note about what different kinds of institutions are good at. One of these systems is good at building excellent instruments and bad at guaranteeing them a ride. The other is good at guaranteeing the ride.

The picture at the top of this email — the one showing you exactly where Chang'e-7 is going — was made by LRO's cameras and by ShadowCam, the NASA instrument riding on Korea's Danuri. A seventeen-year-old American orbiter and a Korean one carrying an American camera, mapping the ground a Chinese lander will aim for.

That is the actual state of lunar exploration in 2026, and I find it more interesting than any race.

Mars was genuinely quiet this week — no new results, no anomalies, nothing announced. A quiet week on Mars is a good week on Mars. You can watch the whole board on the lunar dashboard.
