Russian Proton Rocket Failure Video new

I have mixed feelings about this. I hate to see worthy missions fail, but I'm fascinated by large explosions.

Was it a test, or was it carrying something? (I can't get to the vid.)

It was a commercial launch to send up three navigation satellites (GLONASS; the Russian equivalent of our GPS satellites). Looks like maybe a one or two engine failure (it has six located somewhat off the main axis of the vehicle) that lead to an instability that sent the guidance out to lunch. The video shows it wobbling slowly back and forth as it rose and then rolling and pitching over to the point where the payload section broke away shortly before the rocket impacted the ground. This is the fifth failure in the Proton program in the past two years. What is most interesting is that the Russian Proton rocket does not carry a destruct package to destroy the bird if or when it goes bananas. Even the Space Shuttle had a self-destruct package. Clear skies to you.

Apparently they have no range safety officer in charge of destroying an errant booster.

In this case, it seems like being allowed to impact the ground at a safe distance from the launch pad may have been the best event anyway. Had it been destroyed before it had completely pitched over, debris would have rained down over the facilities.

No, the forward payload section of the rocket was completely torn away (and into pieces) from the extreme aerodynamic loads on the vehicle shortly before the rocket hit the ground. The payload section then smashed into the ground, as it had no parachute for recovery. It was pretty much a total loss. Clear skies to you.

A good self-destruct would have started the burning higher up (it crashed only 1.6 miles from the launch site). Baikonur is only 38 miles away and I am sure that they would have been more than a little irritated if that rocket had gone in that direction. There is no excuse for not having a self-destruct system on any large launcher like this. Clear skies to you.

Probably a money-saving decision. Save a few rubles and cross your fingers.
