There does seem to be in the space world a relience on a lot of old tech.
They just spruce it up a bit every so often. This seems to be a general
thing throughout the whole industry. Its as if all the great design work has
frozen in these organisations and therefore its just tweaking around the
edges or in the case of the us, going back in time that is going on.

Says it all really. I guess the problem could be a loot of things, but
generally the system seems robust so...

The Russians are usually reliable with these sorts of things overall.
But, if you look at the details, there have been many problems over the
years. Many of these problems have surfaced as they make changes to
systems in order to "modernize" them. The Soyuz launcher, for example,
recently got a digital control system to replace the old analog one that
used to require rotating the entire launch platform to obtain the
correct launch azimuth. There have been nagging problems with quality
control over the years as well. It's hard to say this early exactly
what caused the current situation, but it could very well be a
combination of factors.

No new news that I can see so far this morning.

and the extra thrust to carry it." - Henry Spencer
