Roscosmos named the cause of the accident after launch from the Vostochny spaceport

The crash of the “Fregat” upper stage (RB) with 19 satellites, launched from the Vostochny cosmodrome Soyuz-2.1b 28 on November 2017, occurred because the control system of the unit calculated the rotation in the wrong direction, the first Deputy Director General of the Roscosmos State Corporation Alexander Ivanov.

According to him, a special commission completed the work and unequivocally established the cause of the accident. It is associated with the imperfection of the software algorithms of the control system of the Republic of Belarus "Fregat", which first appeared only during this launch. "The control system operation algorithm led to an incorrect determination of the orientation of the upper stage after separation from the carrier rocket with the initial azimuths of the rocket and the block on the launch complex of the Vostochny cosmodrome

- Ivanov announced the official conclusion of the commission.

As a result, the booster after turning away from the third stage of the launch vehicle began to turn in the wrong direction, did not manage to finish the maneuver in 55 seconds, and after turning on the propulsion system, lost orientation and fell, specified Ivanov.

Ivanov noted that all the work carried out at the launch site and the technical complex of the cosmodrome during the preparation for launch could not lead to a similar result, and "no comments were made on the operation of the systems of the cosmodrome Vostochny not detected." Also, the commission did not reveal any comments in the work of the launch vehicle.

The overclocking block itself and its component parts (engines, control system) worked in accordance with a predetermined algorithm, which was laid out in 1998 during the creation of this block

- added Ivanov. He clarified that there were no questions to the flight task, to its compilation also found - “the flight task was formed strictly in accordance with the ballistic data protocol”.

Ivanov noted that such problems with the algorithm, which led to the loss of the "Frigate", "are treated by software methods," reports TASS

Why wasn’t all the software rechecked ten times?

. July 21, 1962 from Cape Canaveral, the Atlas launch vehicle carrying the Mariner-1 vehicle, which was supposed to go to Venus, was launched. A few minutes after take-off, the rocket deviated from the course and was blown up for security reasons. Somehow, the hyphen was missing in the reference program, which led to incorrect rocket control - leaving to the left and lowering the nose. The hyphen was also skipped during the previous successful launches of Atlas, but this part of the program was not used, because there was no rupture of radio communications.

For those who make the program, "the eye is blurred", it is difficult to double-check, an error is skipped - brains are on the same track. And the one who checks it is easier for him to write his own version than to catch fleas. After all, errors in the program are also logical, and it is much more difficult to catch them.

[sxfRipper]

A hyphen is missing ... I don’t know how it was in 1962, and now the compiler would simply give an error in such-and-such module on such-and-such line - and EVERYTHING!

[dauria]

and now the compiler would just throw an error

And if there is no syntax error, there are no missing labels, in general there are no errors from the point of view of the compiler, and indeed all the hardware? And does it clearly do what they wrote to him? But the person himself simply did not see that it was possible to get into some ring of the program with other parameters? And when debugging, everything works until that very rare event occurs.

[region58]

A more recent case: on the NASA Mars Climate Orbiter, one system measured momentum in feet per second, and the other in newtons per second. As a result, the station burned out in the atmosphere of Mars

[Igor V]

This is not an error in the program, but an incorrect algorithm, that is, the logic of behavior. At the beginning of the space age there were many similar errors. The most famous, perhaps, is the triggering of the emergency rescue system at the start. Then the start was delayed due to another sensor. The earth during the delay turned more than 7 degrees and the gyroscopes went down. The system decided that it was an accident and launched the SAS, when it was triggered, the descent compartment separated from the control room, the pipelines and hydrogen peroxide, the fuel of the orbital orientation engines broke, poured down onto the carrier. There was a fire and explosion.

But is it really impossible to involve a supercomputer in this business, to create emulation of launch for testing software in different critical situations? The machine’s eyes are not blurred, it will dispassionately fulfill all the given options. As noted in the article, the software was written in 1998 - and what, after that, did not make technological updates to the design of RB that did not entail a change in the software itself? And after that, how was it tested for operability and stability in different operating modes? Everything is strange, more on the great Russian races ... the guild seems ...

Yah? And how then do we run on our computers old software that is not compatible with current OSs, but the same win-applications for Linux? The question here is not about incompatibility, it was necessary to create an environment that emulates the start of the Republic of Belarus and work out all the possible and impossible factors of the block. It makes no sense to guess, but the conclusion suggests itself that means not all the moments worked out, not all taken into account. But experience comes with errors and practice. So, although it is a pity about the unsuccessful launch, no one is safe from this, the main thing is that appropriate conclusions are drawn and measures are taken.

[dauria]

But is it really impossible to involve a supercomputer in this business, to create emulation of launch for testing software in different critical situations? The car's eyes are not blurred

Do you understand that you are proposing to involve a program in the program check? And here's the trick - the more complex the system, the more errors there will be. Errors will appear that were not thought of before. At first it was simple - both the errors were primitive and the failures were purely physical. But already with the advent of conditional rules (and all programming is now finer than jurisprudence), violations of these rules appeared either random or intentional (for example, file structure errors of an old MS-DOS). Do you understand the situation, the hardware is working properly, and the system is sick? It became even worse with Windows - sharing resources added rules, but not all of them comply. There is "garbage" from remote programs, or vice versa - the library is deleted, to which other programs managed to bind.

Soon the computer will be mistaken with purely human errors - "by default", etc. I do not understand, but I thought that ....

A (quality) fault emulator will be much more complicated than the system under test. The more complex the system, the greater the likelihood of errors in it. This is the alphabet.
Where is the guarantee that there will be no critical errors in the emulator?
There is no such guarantee.

Another stupid excuse ... the software was to blame, they launched in the west direction ... no, as always in the east ... we urgently need to learn from the brothels, stop moving and rearrange the beds, and change the staff.

One of the laws of programmers:
Each program has an error; if it is not there, then it was poorly searched.
Resolving the error leads to two new ones.
But seriously, it does not make mistakes only the one who does not work.
Can you imagine how much code this program can have? Personally, I do not. I had to write programs in which the code listing took up hundreds of pages, and the number of files was measured in thousands (although there were tiny ones among them), to check all this is an extremely difficult task.

occurred due to the fact that the control system of the unit calculated the rotation in the wrong direction

as soon as a few people are sent for the “ten” years to places that are not so distant, the falls will stop in the right direction, the rotation will be in the right direction, the separation of satellite devices from the overclocking module will be timely, the solder will be of good quality and the sensors will stand correctly and not up legs.
