Rumbles of a programing error causing the Russian Lunar mission failure.
Perhaps the 84 second burn overflowed the integer (2^6) and was caught by a 2^7s check (127s)
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?
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 😆
