A Russian Proton rocket went out of control and slammed into the steppes of Kazakhstan mere moments after launching from the Baikonur Cosmodrome on Monday night.

The government booster was carrying three Russian navigation satellites on the ill-fated mission that launched at 0238 GMT (10:38 p.m. EDT).

Live video showed the Proton gyrating left and then right as it ascended off the pad before going horizontal, barrel rolling and falling into a nose dive.

....
The crash was broadcast live across the country and fears of a possible toxic fuel leak immediately surfaced following the incident. While no such leak has been confirmed, the rocket was initially carrying over 600 tons of toxic propellants.
...
Experts point to engine failure as the likely cause of the crash.

Must be a whole array of toxic (nuclear?) materials from the crash?

Why would there be nuclear waste from the rocket? It's not nuclear powered. The bigger problem would be the risk the Hydrazine and how it affect the people living in the area. The way it is handled I wouldn't like to think what 600 tons of it can do.

The rocket or the three satellites.

RTG fuel??

The GLONASS satellites are powered by solar panels, so no RTG there. The launch vehicle would use batteries or possibly a fuel cell. The rocket fuel itself is the issue here.

About ten seconds after launch and just before the rocket started to waiver, you can see a large orange streak in the rocket plume. What kind of flight termination system does the Proton have? Automatic, manual, or both? I would have thought the range safety officer would have terminated the flight once the rocket was horizontal.

Answered my own question. Good summary of the flight here: http://www.spaceflight101.com/proton...ock-dm-03-glonass-launch-2013.html

That orange was likely N2O4, Dinitrogen Tetroxide, the fuel used for the rocket.

Great video titan, thanks for sharing!

I find the fact that the Russians have no means of in flight termination by remote control mind boggling! Is there any good reason why they wouldn't put in this fail-safe? I can't think of a good one.

"Russian launchers do not carry a Flight Termination System that could be used to remotely trigger the destruction of the rocket in a scenario like this. The built-in safety system for Russian vehicles is a simple engine shutdown in an emergency situation. The flight control system is programmed to wait at least 42 seconds after liftoff before shutting down the engines in an emergency scenario to make sure the vehicle does not impact near the pad. Proton’s engines were never shut down because by T+42 seconds, the launcher was already back on the ground."

Why would they need another complicated system prone to failure or accidental usage?

These things don't takeoff near tens of thousands of people like rockets from Florida. Even in a runaway like this - the goal is to make sure the thing gets away from the immediate area of the launch out into huge open empty areas. When the rocket started to wavier it was still very close to the pad area and all that expensive infrastructure. Let it get away from the immediate area and not have all that debris falling down on the launch complex.

Yeah but if the pointy end of the rocket was heading toward the launch house you know they would be pondering why they did not have a remote termination system

I wasn't aware that it was a complicated system, and I can't recall hearing of launch officials 'accidentally' blowing up perfectly good rockets.

It was obviously not designed by Dr. Doofenshmirtz.....

In the video, you can see a cloud of what appears to be N2O4 appear around the vehicle at engine start. It dissipates, but then there is a plume of it that appears in the engine exhaust, as fsnuffer noted. Among the things one might suspect is that a pump failure or a combustion chamber rupture occurred at that point. However, the guidance appeared to be in trouble before that. I'm not sure why; according to the Wikipedia article, this version of the Proton-M has closed loop guidance in first stage. Maybe a damaged combustion chamber or nozzle created a badly off-center thrust, or it might just be that the thrust vectoring doesn't have enough authority to compensate for an engine loss that early in the flight profile.
