CBS News just reported that a cargo rocket exploded just after takeoff today. The launch site was in VA. The rocket was unmanned, but no reports yet of any injuries on the ground.
Major oops!
From our point of view, at least this one wasn't carrying two GPS satellites like the Russian one that crashed with two Glonass satellites.
Wow. That reminds me of some Gemini or Mercury attempted launches from back in the early 60s. Looks like they lost a gimble lock and the RSO set it off.
Antares Rocket Carried Heavier Payload
The second stage was larger and heavier and the delivery module was also heavier. Despite the heavier load the first stage did not have more power. (Maybe see below).
The rocket is climbing out a bit slow allowing excessive heat to build up around the rocket motor, probably dropping the compressor capability, hence lowering power and the rocket motor consumes itself in midair. Much too reminiscent of early V2 and US failures.
The 2 main engines were at 108% power, which may have been to provide that extra boost or may be typical for a normal liftoff. With the extra weight in the second stage and payload, rocket weight was in excess of 108% of previous launches. It intrigues me that one goes above the design limits and then is surprised by failure. I will note that the Challenger Space Shuttle exploded within seconds after increasing to 104% power. Also Space Shuttle Columbia filed on re-entry with the heaviest return weight ever attempted.
A couple of cheap strap on SRBs would have been better than the heavier second stage.
It was overcast here so I did not go out to watch the launch which should have been visible to 10° altitude, which is about 60 seconds after liftoff.

That was the first thing I did was check that it was not carrying the new GPS sats.
Guess the space station will be eating cheese and crackers.
