Final cause of the fall of GLONASS satellites

Final cause of the fall of GLONASS satellites

Called the final cause of the fall of GLONASS satellites:

Failure to launch GLONASS satellites on December 5, when three staff fell into the ocean, occurred because of incorrect formulas written in the technical documentation for refueling Block DM-03.

See http://www.lenta.ru/news/2010/12/17/glonass/

They did not use Mathcad by calculations and for documenting the formulas

I hate to break this to you, Valery, but the report is a cover up ...

One my friend wrote me by e-mail:

I would be good to find out about this equation and make Mathcad file with wrong and correct calculations! This would be a great promotion for Mathcad and PTC. But this is probably a secret.


We can try to find this secret in WikiLeaks for example

One real story.
During the Cold War in USSR new ballistic missiles with liquid oxygen as oxidizer were tested. These missiles do not reach the goal. It turned out that we used erroneous data on the density of liquid oxygen.

Correct data on oxygen on Mathcad Server:
