“EagleCam to record lunar landing
Just before landing, at approximately 30 m (98 ft) above the lunar surface, the Odysseus lander will eject the EagleCam camera-equipped CubeSat, which will drop onto the lunar surface near the lander, with an impact velocity of about 10 m/s (22 mph). From the surface the EagleCam will attempt to capture the first third-person images of a lunar landing. The EagleCam will use a Wi-Fi connection to the Odysseus lander to relay its images back to Earth.”
That CubeSat is student built. I wonder what camera they have and how hard it will be to make it record the landing. Will it orient itself during that six-ish second drop or can it move the camera after landing? Does it have a fisheye lens to increase the likelihood of the lander being in its field of vision?
Unfortunately, their project page (https://erau.edu/eaglecam) seems to be light on such details.

That's because of different frequencies and power caps that are enforced by the FCC. If your WiFi broadcast with the same power, the frequency space would be unusable by your neighbors for their WiFi. The range of WiFi is very purposefully sabotaged to make it useful for more than just you.

Assuming you are talking about FCC Part 15 regulations for 2.4 GHz, you couldn't be more wrong. There is no 'sabotage'
The EIRP is 4 watts in 2.4 GHz band. More than enough to wipe out your neighbors. Also more than enough to get absolutely tremendous range in line of sight conditions.
I can purchase and install an unlimited number of 2.4 GHz Part 15 devices, rendering the band useless to anyone so long as I am attempting to use those devices in a manner consistent with their application. As another Part 15 user, you have no recourse. If a licensed user complains to the FCC, they may decide I have to stop using them and notify me as such. Note: one of my neighbors does this, by having an AP on every 2.4 GHz and 5 GHz channel.
Newest Wifi 6 stuff in the US has a power limit on some spectrum and some usages, but nowhere near as low as what I was hoping for.

If you're above the frequency at which the ionosphere becomes reflective (around 30 MHz), why should space be noisier than the Earth's surface? Anything propagating there will reach down here (unless it's something really short wave absorbed by molecular bands in the atmosphere.)
In practice, it's going to be noiser down here, because of all the sources down here.

Noise you can correct for with directional antennas, filters, and/or more signal processing voodoo. Meanwhile you benefit from space being actually empty - no pesky atmosphere in the way to attenuate signals (though also no layers to bounce the signal off), and no other transmitters in your area. Inverse square law works to your advantage in this context.

The simplest way to do it is probably just to have a high quality 360 camera, that way you mostly get around the problem of orientation
6 replies

Yes, but even that isn’t simple, I think. They’d not want to land on top of it, so they’d have to push it out from the lander or have it propel itself away from the lander. If they push it out and it doesn’t have a way to stabilize itself, keeping the lens pointing upwards then will require tight control over that push.
So, I guessed (see below) you’d need power to make the sat orient itself.
However, I googled a bit more, and found this: https://mynews13.com/fl/orlando/space/2024/02/21/embry-riddl..., which says:
“EagleCam will be spring ejected from the Nova-C class lander Odysseus about 30 meters above the lunar surface during the final descent. It will take three images a second from each of its three cameras (a total of nine images a second), capturing its six-second freefall to the surface and Odysseus’ descent and soft landing. About an hour after landing, our team will receive the five images of our choosing. During descent, Dr. Henderson and I will be timing events in landing sequence to match to image numbers to choose the first five images we bring back to Earth. Once we have those images, I will post them directly to @eraueaglecam on Instagram. Shortly after that, they will also be available on @spacetechnologieslab on Instagram and @SpaceTechLab on X (formerly Twitter).”
So, it isn’t a 360 camera, and they’re making 50-ish images and hoping for the best. Doesn’t look like the sat has rockets or that they’re trying to make it possible to make more photos after impact on the moon.
If my guesses/intuition is right we won’t see the actual touchdown (still cool to have anything, of course), but corrections welcome.

Ownership rights and various kinds of access rights are not identical and often conflated.
For example, if I own a water well, I don’t necessarily have the rights to do whatever I want with it. Some jurisdictions might let me pump out as much water as I want, but even those will punish me for blatantly polluting it (one would hope).
What some people think of as something akin to “total ownership” — completely unlimited access — would be tantamount to putting one’s “rights” above everyone else’s. Even dictators usually have some limits on their power, whether by laws, norms, or geopolitical pressures.

better, lighter-weight computing stacks have been a huge boost; that's what made cubesats possible. but the much bigger deal is the dramatic drop in launch costs driven by spacex, even though so far that's only a factor of 3.4 https://ourworldindata.org/grapher/cost-space-launches-low-e...
with lightweight computers driven by the cellphone industry, it became possible for a small team or even individual to launch a low-power ham radio satellite or weather satellite. but they can't launch a high-resolution space telescope, earth observing satellite, or high-power communications satellite, nor can they do laser communication pointcasting. and lightweight computers are a crucial enabler for starlink-style communications constellations, but there's only one of those, because that's still a big-money kind of project
suppose that, instead, you had 01980s computing power, but the cost of space launch dropped by a factor of 100. if you need to launch a 200-kg satellite to get the sky-observing optical aperture you're looking for so diffraction doesn't cremate you, you don't care if the onboard computers weigh 1 gram or 10 kilograms. (i mean, you do care, because it lets you cut your launch budget 10%, but it's not a dominant determinant of viability.) with saturn v or zenit 2, according to the plot linked above, that launch would cost you a million dollars. today, at falcon heavy's 1500 dollars per kg, it's 300,000 dollars, which is already a radically more feasible project
spacex's 'starship' is supposed to carry 150 tonnes to leo for 10 million dollars. that's 70 dollars a kilogram. our hypothetical 200-kg aditya athalye space telescope satellite would then cost 14000 dollars to launch. it becomes a hobby project comparable in cost to an engine lathe or a camper van. this would change the economics of space in a profound way, far beyond what cellphone chips have done
for comparison, the csis aerospace security project number for https://en.wikipedia.org/wiki/Scout_(rocket_family) on that chart was 118500 dollars per kg in 01961. (but of course you couldn't launch a cubesat on it for that price; it was a military thing.) by 01967 saturn v had brought that down by a factor of 22. after that it remained constant for 43 years until falcon 9 in 02010. starship, if it works, will reduce launch costs by that same factor of 22 over the current falcon heavy number i described above, and by a factor of 73 over saturn v

The big improvement is not launch costs, but miniaturization and automation. A university team can make a credible lunar rover or cubesat today using off-the-shelf components. Unlike launch vehicles, that technology did not exist in 001960, or even 002000, at any price.

i came here for an argument, but this is just contradiction
it doesn't matter if you can make a credible lunar rover or not if the price to launch it is three times the grant the nsf will give your university team. given that nasa published their lunar roving vehicle documentation in mostly 0001973, down to circuit schematics and some machining dimensions, i'm pretty sure a university team in 00002000 could have duplicated it for less than the several million dollars the launch would cost. it only took boeing 17 months to design and build them in the first place, and they mostly use technology from the 000001940s (aluminum tubing, nylon webbing, wire mesh wheels, silver-zinc plexiglass batteries, brushed dc motors, cable brakes; fiberglass arm rests and fenders were apparently the highest-tech part and, unsurprisingly, the part that failed)
https://www.nasa.gov/history/alsj/alsj-LRVdocs.html
with respect to cubesats, you're in violent agreement with my comment. you obviously can't put a trs-80 in a cubesat. in 0000002000 you could put a basic stamp in it, but you couldn't get mems gyros and accelerometers, and you weren't going to be able to run your star tracker camera off a pic16. computer and imu miniaturization is a big deal for cubesats. that's one of the main points of my comment
the other main point is that it isn't nearly as big a deal for bigger satellites; when we were launching cubesats (before i joined the team) it was really important that we could use tiny cellphone components, but once we were launching 37kg monstrosities, the fact that the gumstix boards only weighed a few grams was just nice, not critical. the optics weighed a lot more

Oh I don't dispute the fact that reusable vehicles are an incredible leap forward. Anything that manages to launch significantly more payload cheaper and more frequently is awesome.
That said, things like reusability work at all because of precision control which, as far as I can tell, is near-impossible to do in a lightweight package without the cooperation of a compute stack. Same for other kinds of soft landings and autonomous control scenarios.
As an aside: achievements like reusable rockets also became possible because of advances in materials research driven by advances in computer simulation and computer-aided manufacturing. So this is perhaps another under-appreciated layer of the rocketry compute stack.

yes, those are excellent points i strongly agree with
what kinds of new materials are they using in the falcon rockets, do you know?
quite aside from the weight, latency is extremely important to precision control; a factor of 10 in latency may be equivalent to 100× or 1000× more sensor error. so, even if weight was no object and you could mount a dozen 5-tonne 10-megaflops cdc 6600 supercomputers on your reusable rocket as the guidance system, you might still be better off with a 100-megaflops high-end microcontroller, just because it can respond more rapidly to perturbations of homeostasis

The decline in price per kg from Falcon 9 has made a big difference and yet it's nowhere near as impactful as Starship is going to be... falcon 9 is either too powerful for LEO missions and limited by fairing volume( so can't really launch space stations on a falcon 9) or too weak to push further into GEO and into the solar system.

This reminds me of countries who send pregnant women to antartica to (somehow) strengthen their land claims: https://medium.com/good-to-know/why-11-babies-have-been-born...
Like antartica, I'm sure someone with guns will tell us who really owns the moon as soon as it actually becomes relevant.

I didn't know about them. I recently watched the whole https://en.wikipedia.org/wiki/For_All_Mankind_(TV_series) and was mesmerized by it - it's alternative reality fiction, where a private company comes to land on Mars!

Yeah, For All Mankind is a great show for people who are excited about this kind of stuff. It's an alternative-history fictional drama exploring "What if" the space race never ended.

Yep. Highly enjoyed its Season 1, but I wished I never watched any further - it feels complete at this point and the later seasons destroy the impression. Kind of like with The Matrix.
Note: some people have an opposite opinion, that the interesting stuff starts at Season 3.

Agreed, Season 1 was by far the best. I'm re-watching the whole thing with my spouse and in some ways it's more fun the second time around (surely biased because of the shared experience).
Some shows are like that - I didn't think Star Trek Deep Space Nine was all that hot first time around, appreciated it much more years later on a rewatch (the supporting characters are awesome). Maybe in part it's adjusted expectations ;-).

I wanted to like it, and having some (reasonably-)big-budget visualization made of proposed rockets like Sea Dragon was great. But the (imo) awful dialog made the show unwatchable for me, and they did a lot of scientifically silly stuff like taking the Space Shuttle to the moon.

It's interesting how this feels like a big deal; when I learned of this yesterday, I almost forgot that there have been almost 30 missions to Mars (which I assume is much harder and more expensive) in the years since the last moon landing.

which I assume is much harder and more expensive
Manned space missions are significantly more expensive (and complicated) than robotic missions. (Otherwise, we'd be sending a lot more people into space.)
Let's do a little bit of back-of-the-envelope Googling:
From https://www.planetary.org/space-policy/cost-of-apollo
The United States spent $25.8 billion on Project Apollo between 1960 and 1973, or approximately $257 billion when adjusted for inflation to 2020 dollars.
From https://www.planetary.org/space-policy/cost-of-the-mars-expl....
The Mars Exploration Rover (MER) mission cost $1.08 billion. Of that amount, $744 million was spent on spacecraft development and launch; $335.8 million was spent on 15 years of mission operations.
So it looks like "manned" space missions cost at least 100x the cost of sending a robot.

The post you're replying to is comparing robotic missions to Mars vs. the moon.
Mars is orders of magnitude harder to land on because of its atmosphere, stronger gravity, and the need to keep your robot healthy on the long trip over.

It is a big deal!
While just landing on the moon is definitely much simpler than a Mars mission, this lander is a part of the Artemis program; it's one of the first steps towards developing the Artemis base camp on the moon.

I'm more excited about the moon. Being that much closer is a big deal. This company is looking to make sending stuff to the moon (not sure about getting stuff back) a reliable & vaguely cost effective thing to do.
There's probably valuable stuff on the moon and even if not, it's learning a load of things about going further afield. Lots of science fiction about the asteroid belt beyond mars.

This is great, it really proves that the free market can be just as innovative and efficient as the public sector. They managed to get there less than 50 years after the taxpayer funded space guys did. No small feat! Imagine all the things they must've learned along the way!

Pretty cheeky of Columbia to sponsor this. They couldn't even make the shoes I bought that were 'absolutely waterproof' actually waterproof. A super light rain would result in wet feet. This didn't even happen in normal sneakers.

Columbia is known for incredibly good lifetime warranty- contact them and get something that works for free.
I use mostly Columbia gear for some pretty serious outdoor adventures, and generally consider their waterproof tech, especially outdry rain shells to be the best you can get at any price. However, I don't (and wouldn't) use any of their footwear.
For waterproof footwear, breathable membranes don't work well in my experience, they quickly tear and leak. The membranes are just too delicate for the forces and flexing on a boot. A really well built traditional leather boot with external waterproofing like Sno Seal applied daily is both more breathable, and more waterproof. Failing that, heavy rubber boots like commercial fisherman wear are really the only totally waterproof footwear.

Now to the problem with YouTube, and I'm sick and tired of reporting this, because by now they should have an automated solution for this, look at this link:
https://www.youtube.com/hashtag/im1
Channels named "SpaceX [LIVE]" [0], "SpaceX" (which is actually @uyenmusic with 148.000 subscribers), and so on.
Most of these channels have no videos except for that single live stream, occasionally inserting QR-codes with crypto-scams. Like the first one I mentioned.
Huge crypto-giveaway during to the launch!
During this unique event, you have the opportunity to take a share of 1.000 BTC & 10.000 ETH & 100.000.000 DOGE & 10.000.000 USDT. Have a look at the rules and don't miss out on this. You can only participate once!
And the most interesting thing about this video is that they are using AI to make Elon Musk say that you should scan the QR-code and that you will get the crypto. 100% sounds like him.

The next stage in this project is the ice-drilling PRIME-1 - which might rely on the success of this stage? Details:
"The [Odyssus] Nova-C Lander is a tall hexagonal cylinder on 6 landing legs. It is capable of carrying 100 to 130 kg of payload to the surface. It uses solar panels to generate 200 W of power on the surface. Propulsion and landing use liquid methane as fuel and liquid oxygen as an oxidizer. The PRIME-1 mission has two primary components, The Regolith and Ice Drill for Exploring New Terrain (TRIDENT) and the Mass Spectrometer observing lunar operations (MSolo). TRIDENT is an augering drill approximately 1 meter long. The drill is able to stop at any depth as commanded from the ground and deposit and deposit its sample on the surface for analysis. MSolo is a commercial off the shelf (COTS) mass spectrometer modified for spaceflight and lunar operations. Total PRIME-1 payload mass is about 40 kg."

the Odysseus lander will eject the EagleCam camera-equipped CubeSat, which will drop onto the lunar surface near the lander
So the first non-government device to land on moon will be viewed trying to land by a device also non-government (but part of the lander) that lands on the moon first? I guess that evens out.

Wallace and Gromit did it a long time ago.
The US flag on the early moon landings, was absolutely an advertisement; the whole thing was done as a propaganda riposte to the Soviet Union's Sputnik. Doesn't mean it's not awesome.
There is a meaningful difference between national pride and 2 for 1 at Dominos.
True, for instance no wars have yet been fought over 2 for 1 at Dominos.
Not yet
This is the first step.
2 for 1 at Dominos has also, strangely enough, never protected anyone.
Odd that.
In 2001 Pizza Hut actually had its logo on a Russian rocket, and delivered pizza to cosmonauts on ISS as part of a robotic resupply mission.
Diseased worldview
How dare they attempt to defray their costs.
How dare they put an ad on the moon.
We are truly spreading the worst of humanity into the cosmos. Good job it's only us that appear able to witness it.
Defraying costs by using ads is a strawman. If you can't afford to do something, maybe don't do it. If you really, really want to do it, maybe ask yourself if the world genuinely needs what you're doing. If it does, find a way. If the only way you can do it is by selling advertising, you've taken as mis-step.
Clearly they can afford to do what they just did.
Oh, you don't like how they raised money? Good, pay attention to something else, they aren't doing things for your approval.
I would dearly love to "pay attention" somewhere that isn't plastered in advertising.
They didn't do it for approval, but they sure as shit didn't ask for approval either.
And I'd like to see a breakdown of exactly how much the ad revenue contributed to payload delivery.
That's an extreme position to take that rests on the claim that sponsorship/advertising is objectively bad.
Media & journalism have been underpinned by advertising for over a century. Tons of educational and informative services are available to the public for free because of advertising. Sponsorship has built art galleries, hospital wings, research centers, etc.
In this case, there's a relatively innocuous logo on a robotic lander that is 230k miles away on a desolate rock. It's not like this is a billboard in a nature preserve.
Whether advertising is objectively bad isn't necessarily the debate, but at some point it can cross a line. That line might be different for everyone, but most people will have it. You yourself give an example of something you suggest might be unaccaptable to some:
Where's the line? Why shouldn't we put billboards in nature preserves?
It's almost as bad as when they put the Castile flag on the Santa Maria!
This feels unnecessary cynical. I could understand if the spacecraft said "Drink Ovaltine" or something else just advertising with paid placement, but the brand marks on it are just highlighting the organizations the actually built the thing. I was originally confused/skeptical about Columbia, but they did actually contribute to the design and construction of the lander, even if this press release is a little puffed up: https://investor.columbia.com/news-events/press-releases/det....
Also, you say "It's all just egos and entertainment now." What do you think it was in 1969? Is "beat the Russians" somehow a more noble goal than "sell a product"?
Eventually, spacecraft will look like a NASCAR paint job.
Perhaps briefly. Eventually they will look like cargo ships.
What makes you think a cargo ship can't have a NASCAR paint job?
It's not that they can't, it's that they don't.
Back when I used to help organized and run a technology-specific usergroup, where we were constantly working corporate sponsors for donations to pay for food/beverages, I joked that on meeting nights I would gladly wear a NASCAR style jumpsuit, emblazoned with every sponsor brand logo/slogan. At least we would be honest shills. Sigh... no one took me up on the offer.
I still think that politicians should wear a jumpsuit with all of their corporate sponsors
I get where you're coming from with the AD on the spacecraft. It's gross to see an ad for a clothing company on the moon.
But, NASA is predominately displayed on all of the original moonshot crafts. That's an advertisement for that organization. . .
And, I'm 100% sure ego had nearly everything to do with the original space race. Beating the Russians and what-not. That seems, in hindsight, to be very ego driven?
I think saying "this organization built this craft that went to space" is a bit different than "buy shit from this other company"
The Columbia logo on this craft is both. They're advertising the brand in a very cool and unique way AND they contributed significant heat shield technology to the craft itself.
NASA is an organization that represents the collective efforts of Americans (and others!). Columbia clothing is a private business that maximizes profit.
It's about self-identification not advertisement. And NASA isn't a privately-owned for-profit corporation. It's like putting "US NAVY" on a battleship, except instead it's a vehicle furthering mankind's technological development.
Experience is irreproducible. It depends on too many factors, we even don't know the full list of them, and some of them change irreversibly with time passing. You will not be 10 years old anymore. It is not a good reason for a depression, you can experience world now like you couldn't being a 10 year old boy.
Actually one of the absolute best things about having kids, that is not reproducible for no-child lifestyles, is seeing everything for the first time through their eyes.
All the other stuff people say about parenting can be reproduced via service or volunteering or something else. But that experience absolutely is unique.
Magic is real. The world is wild and exciting, and it's all there for that kid. It's amazing to watch and be a part of.
So, while you can never go back to being at 10 year old boy, you absolutely can get a taste of what that's like via adoption or having your own. In my opinion, that is.
Ahh yes, empathy can give us experiences we are unable to get ourselves.
I see what you did there, heh!
Just here to both support and counter this a bit. Kids are absolutely a great way to see joy in the world again!
... but they don't have to be yours. I've supervised those for my peers, played temporary dad, all of it.
Sure, it's time-boxed, but that may be the goal. Trading seeing "everything" new, for "plenty"
We planted an American flag on the moon. An advertisement for the Coca-Cola of American imperialism versus the Pepsi of Soviet communism. The entire space race was literally nothing but ego and propaganda.
We also hit a few golf balls. Give us some credit.
That's because you were a child at the time. A child now will most likely have the same sense of awe and wonder you had, not the cynical point of view you've developed over time.
A child now will be totally unaware about that because he will be occupied doomscrolling whatever trends is current now on TikTok.
I’m just glad it’s not something “too on the nose” comedically, like for Coca-Cola or something that makes me think of Wall-E. At least it’s a hiking/adventurey brand and not KFC.
The first Mars colonizers will stick a coca-cola flag in and everyone but few PR people will sigh collectively
the moon landing rocket said "usa" on the side and had flags. that's the same thing, just a bigger corporation
I wonder what kind of analytics the adtech will bring them, and how invasive to their privacy it will be
It's carrying a payload for Columbia, among other things, which makes this type of marking generally called a “sponsor logo” rather than an “advertisement”:
“Besides NASA’s tech and navigation experiments, Intuitive Machines sold space on the lander to Columbia Sportswear to fly its newest insulating jacket fabric; sculptor Jeff Koons for 125 mini moon figurines; and Embry-Riddle Aeronautical University for a set of cameras to capture pictures of the descending lander.”
