there's no way engine burn time is graduated in seconds on a spacecraft in 2023, that's way too coarse

i can see doing one burn that is kind of rough, then evaluating the situation and applying some correction?
Why do you expect the Russian space program to be using new equipment after the antique show of an invasion in Ukraine?
Every country uses a combination of older and newer equipment in any war. The war propaganda wizards just try to make things like that look unique to Russia.
I don't think most countries are using first aid kits from the 70s.
I would take what our jingoistic media and talking heads say with a very large pinch of salt. It's quite disrespectful to Ukrainian soldiers to say they've been facing an "antique show of an invasion", not to mention Russian engineers. Propaganda aside, both sides have fought hard in what has been a very modern war.
I've more paid attention to Ukranians' accounts of events than major media coverage. Lots of pictures of really old tanks being dragged away by farm equipment and other extremely dated supplies being found. If this is anyone's propaganda it's Ukraine's, in which case I'm happy to participate.
Nobody said it hasn't been hellish for Ukraine, or that it hasn't been a hard fight. Even if they were equipped with entirely WW2-era supplies, an invasion is an invasion, and by all accounts this has been a particularly cruel and brutal invasion.
I really don't care at all about being fair to Russian engineers at the moment.
If this is anyone’s propaganda it’s Ukraine’s, in which case I’m happy to participate.
Why is that? It's a blood bath and we shouldn't support any propaganda that perpetuates wars.
Uhh, don't think it's the propaganda that's perpetuating the war. That'd be the invasion.
Found the Russian sympathizer though.
Even the phrase "Russian sympathizer" is propaganda. Simple messaging sinks in.
I just have an interest in the wars around the world that the West (the UK, USA, Israel, France) are magically omnipresent in and around. With of course completely coincidental geopolitical prizes to win, as 'we' play Team NATO World Police around the world after the first rounds of our Confessions of an Economic Hitman tactics fail. The same old players pop up in every new episode of their perpetual war plan.
This is another episode. All wrapped up in a completely independent narrative with a different cartoon mad man to fight and a nice humanitarian angle so that people get all emotionally attached and don't join the dots.
Looking forward to T-18 sightings by this time next year . . .
Is that like a robot infant Arnold?
Why in God's name would you use a 6-bit signed integer for anything on a spacecraft? I know space-certified chips are pretty barebones, but surely not that bare bones...
This is Roscosmos we're talking about here. First lunar mission in 25 years??
The tweet you link didn't indicate that. It said that an engine failure likely caused the overrun, running for 127 seconds instead of the planned 84. Why would something have a 2^7 int size check?
Edit: Quoted
The head of Roscosmos Yuri Borisov said that the main cause of the #Luna25 crash was an engine failure. Instead of the planned 84 seconds, he worked 127 seconds.
Am I missing something?
There's further discussion of possible explanations in the replies
Ah I think it's Twitter's new thing where you can't see replies of your not logged in.
what do we say to the god of software bugs ruining our space exploration? not today!
one of these days we will finally say it, but... not today 😆
Not today, because the date overflowed a counter somewhere.
