Orbital Sciences just can't seem to catch a break. Monday's launch of its Antares rocket was scrubbed by a rogue sailboat and on Tuesday the rocket exploded just seconds after launching from NASA's Wallops Flight Facility in Virginia. Antares rocket fails There has been a vehicle anomaly. We will update as soon as we are …

    Is it the video or is my connection?

    I've watched this several times and the rocket lifts and then seems to hang on its tail fire before rising again. Around the 3:00 mark on the video. I'm also surprised to see buildings that close to the Launchpad but that could be compression from the telephoto lens.

    1. Bubba Von Braun

      Re: Is it the video or is my connection?

      Nope.. it doesn't stop at 3:00 if you watch the LOX vent it continues to move upwards, (the puff's coming off the side of the rocket)

      Not sure though most rockets cease venting to pressurize the propellant/oxidizer.. don't have Antares details, maybe that's the beginning of the failure, and overpressure in the oxidizer system. Have to go find footage of the previous Antares launch

        Re: Is it the video or is my connection?

        ** Update**

        Just looked at the ORB-2 launch video and the venting occurs a couple of times on liftoff so nothing abnormal there then.

      I'm interested to know why at 3:07 the exhaust brightens considerably, but appears to be still constrained in the proper downward direction. One second later the whole things explodes. So is that a throttle up? I'm not sure that it is: why wouldn't you want 100% thrust from the moment it leaves the launch pad? On the other hand I'd have thought that quite a lot of failures would result in flame going everywhere immediately rather than being constrained so.

      Notice the turbo pump blade disks spinning, spiralling away like some sort of firework? Pretty!

      1. John Robson Silver badge

        Re: Is it the video or is my connection?

        Sounded like they were going for 108% thrust at the time - which is "normal".

        Full thrust from the rockets would destroy the launchpad (yes, I know this did some of that as well), as well as being possibly unstable for the vehicle. Ramping the throttle up allows for smoother flight.

    Russian conspiracy?

    Looks like a classic engine failure on liftoff, looks like one failed and took out the other engine.

    Curious note, these engines supplied by AeroJet are the same as the Russian NK-33, Seems these engines like to perform as they did on the N1.. or is Vladimir having some fun at Orbitals expense ;-)

      Not just the same as, they're actual engines built for the N1 before it was cancelled that have been in storage ever since. Another one exploded on the test stand recently.

        Ah but these motors at 1960's vintage... ex-surplus from the N1-F they are an awesome motor, and something the US has not been able to replicate.

        Most liquid motors are driven by a Turbo pump that itself uses some of the fuel/oxidizer. The exhaust is then dumped out the side as a vent near the main chamber. (see this footage http://www.youtube.com/watch?v=Ejx3jTRD_ME for a clear picture of an open loop engine) these motors don't do they they put the exhaust stream into the combustion chamber increasing the efficiency. The Soviets overcame the metallurgy and other issues associated with doing this closed loop system. Result higher performance/weight and why Lockheed and AeroJet beat a path to their door. Atlas uses a different version but same concept a closed loop.

          Re: just like the good old days.

          Turbopumps are notorious for being a failure point but it appears in this case either a nozzle or a fuel line has ruptured. Although the video is not of sufficient quality to say for sure but before the explosion there was a big flare up in the direction of the exhaust, which suggests that the fuel was still being supplied at pressure for a while but it was burning outside of containment.

        3. Brian Morrison

          Re: just like the good old days.

          The big difference with these NK33 closed cycle engines (like the Rocketdyne F1 and the SSME the turbopump exhaust reenters the combustion chamber) is that they run the turbopump oxidiser rich rather than fuel rich. This is much more efficient, but it has a side-effect that the turbopump casing can burn through very rapidly if something goes wrong. 1" of hardened steel lasts less than 100ms in these cases...

          Re: just like the good old days.

          Pity that the Russians never really had a successful launch. As I recall, the lead designer had an easy chair on the launch pad to oversee everything prior to launch and then BANG! The thing blew up on the pad while fueling. Killed him and something 200 others also.

          There's a couple of vids out there on Youtube and if I'm remembering right, every launch stack blew up as some point before the second stage could fire. I might be wrong. Feel free to correct me and slap me upside the head.

      We have a couple of instruments sitting in a glass case at work that were dug out from 6 feet of French Guyanian swamp after the first Ariane 5 exploded.

      After falling 5 miles, being buried in that much mud, dug up and rinsed off by the French Foreign Legion, then sitting in storage for a decade - there are _still_ high enough levels of hydrazine contamination on them to make them unwise to handle without gloves.

          I used to work with diazomethane. It's a very effective methylating agent in synthetic chemistry, but you can't use it anywhere near ground-glass joints as it has a purported habit of crystallizing onto them and exploding. Luckily I never experienced this. I did learn to keep a close eye on the thermometer to make sure the ether it's dissolved in stays cold though!

          Preparation instructions include the use of a blast shield, and as well as being explosive, the stuff is acutely and extremely toxic!

    But the failure isn't just bad news for the company itself. It's much, much worse for those researchers and scientists who had cargo aboard the rocket. Some of these experiments have taken years to devise, obtain funding for, get accepted for the mission, and then package for orbital transfer. All that effort is now destroyed.

    Engine Anomaly

    Notice that the vehicle drifts to the right on takeoff. This indicates reduced thrust on one of the engines, which leads to that 'catastrophic failure' that NASA talks about.

    1. Bubba Von Braun

      Re: Engine Anomaly

      Look at the ORB-2 flight liftoff footage, it also shows a movement to the left of frame on liftoff. The guidance system would compensate for asymmetric thrust by gimbaling the engine, to maintain the desired direction of flight. Will be interesting to see what actually occurred.

    2. Uncle Ron

      Re: Engine Anomaly

      I have watched two other Antares launches and they all seem to have this side-step right after lift-off. Very unnerving and seems wrong. Might be an artifact of having only two engines vs 5 for Saturn V and 9 for SpaceX thing. Thrust vectoring is more difficult with just 2. Anyway, it doesn't seem like an "anomaly."

    I was watching this live and thought...hmm, that 90 degree roll at launch dosn't look healthy.

    This Antares launch looked slightly odd right from the start - to me it seems like the hot end drifts slightly to the left (towards the launch tower) at release, then corrects a couple of seconds later, but it is hard to tell as the camera is moving a bit too.

      The 90 degree roll is probably to align the guidance platform to the required trajectory. Saturn and Shuttle did exactly this.

    Second stage engine problems aren't that rare. One left two GPS satellites in the wrong orbit earlier this year. SpaceX had one on one resupply mission. It reached the ISS as planned but left a satellite (secondary mission) in the wrong place. I don't see why first stage failures should be rarer, but they do seem to be.

    Obviously they can be more spectacular and cause damage to the launch site, but that doesn't mean that the cause of the problem is more serious.

    1. Vulch

      The SpaceX one was a first stage problem. They lost an engine on the way up so the other 8 ran longer, that left everything in slightly the wrong position so they couldn't do the second burn after the Dragon separated to get the Orbcomm secondary payload in the right orbit.

      First stage engine problems aren't unusual, but they frequently show up before the rocket has left the ground so everything gets shut down and can be fixed.
