If Russia's DSN is confined to Russia, it would limit lunar visibility – but not so much due to latitude as highlighted in Tilley's tweets, but simple longitude limits. From 50° N., the Moon's altitude currently peaks around 40° and exceeds 30° above the horizon for ~6 hours/day. Multiple in-country stations in the East and West should provide Russia with pretty wide comm windows.tracker Scott Tilley noted that the country's ability to communicate with Luna 25 will be limited to when the Moon is visible over Russia. There are relatively few of these opportunities in the days ahead.
I'm betting the potato battery didn't last as long as planned. Shoulda used a bigger potato.
That dictator doesn't even have the courage to go in public.Here’s hoping that Putin has the courage to go up there and fix it himself.
Shit, with all the suicide drones buzzing around Moscow, I wouldn't either if I was him lolThat dictator doesn't even have the courage to go in public.
Especially when they spend the rest of it on a senseless, atrocious, wasteful, and completely unwinnable war.When you give half your country's GDP to like a dozen oligarchs it might make it difficult to function as a nation? Who'd have thought.
Vlad, you've lost ANOTHER spaceship?
Not wanting to jinx it by saying it loud, but I am still hoping for a nice and very energetic lithobraking manoeuvre from Luna 25. Just losing comms with it still being in the pre‑landing orbit would be kinda anti‑climatic!
That would serve them right, IMO. Although I am pretty sure TASS would still try to twist a high‑speed lithobraking crash event into a "very successful landing" somehow...
Given the longitudinal extent of Russia's territory, it should be closer to 18 hours a day. Their lack of tracking ability is no one else's fault but their own.
Also, the launch complex is in Kazakhstan.Russia's first Lunar mission.
Calling the previous Soviet missions "Russian" is rather inaccurate, especially considering that most of the key people in the Soviet space program were Ukrainian.
Nothing wrong with having a space launch complex in a friendly neighbouring country...Also, the launch complex is in Kazakhstan.
If the probe is in lunar orbit, it will also be behind the moon half the time. That would cut communication opportunities to six hours an earth day.That seems very misleading. The moon is visible over Russia 12 hours per day, just like everywhere else in the world. Russia's lack of access to the US's Deep Space Network means they don't have 24 hour a day visibility, but I wouldn't call 12 hours a day "relatively few". Tilley's post was clear but the characterization of it in the article is misleading.
As much abhorrent as thar strike was, please let's keep the numbers straight: the last official toll was around 7 civilians killed and 117 wounded so far. Which is a lot by any count, obviously, and quite inexcusable. The numbers might change yet, of course – probably quite a bit upwards, unfortunately, but please let's keep it official.Sadly, the missile sent towards Chernihiv hit its target and successfully killed 100 civilians including children. If only that one was as faulty as Luna-25.
Not according to the new Russian school textbooks.Russia's first Lunar mission.

Eduard Khil's "Trololo Song" would be the perfect chef's kiss...I was just listening to a podcast about how terrible satellite security often is, and how trivial it is for ordinary people to get access to ground stations - you can literally rent time on a GS network from Amazon or Microsoft.
It's doubtful, but not impossible, that someone took advantage of downtime and sent disruptive commands to the spacecraft. If it broadcasts a rickroll or the bayractar song before crashing, I'm gonna cheer.
note: let me just say this is VERY doubtful. Russia doesn't need any help to fuck things up, and space is hard.
Do they say that radar was invented by Radar Radiovich Radiovochenko by any chance?Not according to the new Russian school textbooks.
Some people here at my university need to pay attention to this. They build instruments to measure micrometeorites and dust in space. They really need to get working on this unknown Russian technology which seems to increase the flux of micrometeorites to many orders of magnitude above natural values.Oh no. Not again.
Reuters is reporting that the Russians are reporting that the craft was hit by a micrometeorite.
I'd say this mission was well within the capabilities of the Soviet Union. Which says something about the current Russian capabilities.Obviously this failed. Ruzzia does not have the tech to go to the moon. Hell, they can barely make a progress capsule that doesn't have holes in it. Their only tech is ancient soviet stuff and that's not going to cut it for a complex mission like that.
Did you mean a penchant?a panache for invading your neighbours
Most likely not. Most lunar orbits are rather unstable. I haven't seen much on what's likely with this one, though, and I have Baldur's Gate 3 to play rather than look it up.Serious question: say for the sake of argument it's in orbit, but tumbling. And that Russia can't reestablish comms with it. So it just keeps orbiting the moon for, like, ever, in the way and useless, as micro-meteors slowly nibble away at it?
No. Unless the Russians are insane and incompetent (and, I guess that's a possibility given the former head of Roscosmos, among other things...) that can't happen. The command dictionary would be restricted if not classified, and there would be back-and-forth verification that the commands were correctly received. I wouldn't say pirating a spacecraft is impossible, but it would take a lot of resources, both hacking the operator's ground system and having some deep space antennas. I don't think there are even half a dozen countries who could do it, and none care enough to risk the political fallout if they got caught.Not saying that this is what happened, but this kinds of missions that receive commands from Earth, what kind of protections do they have for malicious actors? Could somebody with a powerful transmitter send a replay attack to this spacecraft?
Those are generally commercial satellites. For something like JPL's operations network, you very definitely can't rent an account from Amazon. Their security is less impressive than they claim, but it's not that bad. I would expect the Russians to be even more paranoid about things like that, although they gap between claims and reality is probably greater.I was just listening to a podcast about how terrible satellite security often is, and how trivial it is for ordinary people to get access to ground stations - you can literally rent time on a GS network from Amazon or Microsoft.

They're certainly not doing it with panache.Did you mean a penchant?
Lunar orbits aren't all that stable, because the moon is lumpy.Serious question: say for the sake of argument it's in orbit, but tumbling. And that Russia can't reestablish comms with it.

In low Earth orbit. That's easy. When my lab had some communications problems with a CubeSat, we actually got some help from a ham radio hobbyist who lived farther from ground-based interference than the antenna on our building's roof. But even the Moon is much farther away and communications require things like big, directional antennas. Which are, for all practical purposes, at least, mid-range radio telescopes.Doesn't take a nation state to send commands into space:

My thought exactly.They're certainly not doing it with panache.
Do they? I know the Soviets had several such ships. But I thought they most capable one (Nedelin class, I think) were retired long ago and not replaced. What sort of ship-based, deep space communications assets do the Russians currently have?They also have a comm ship in the Pacific, so more like 24 hours.
