    didnt the esa gps satellites fail to get to where they were supposed to go earlier this year and have to be scrapped.

    I reckon I could put 1 on the moon for $5.

    Russian rocket manufacturer insists it is not to blame for failed Antares launch

    theguardian.com/science/2014/oct/29/russian-rocket-crash-virginia

    $200 Million hit, 15% share dive, verbal fisticuffs on the use of the different modules on the ISS starting to get teeth -- a carry over from the sanctions due to the bullsh1t happening in Ukraine.

    Rocket is a 40yo modified Russian yoke, experts reckon stage 2 fired early.

    Another unmanned rocket has left Kazakhstan with 3 Tonnes of supplies for the folks on the station.

    Fired early?? Through the fuel tanks of the first stage? That would be a first!

    I had another look at the launch video and the second stage definitely did not fire early. It all points to the first stage engine area.

    Common occurence at the beginning of the space era apparently and looked like this explosion when it did happen.

    We'll know in a few weeks anyway.

    Apparently so. Youtube might have videos...
    I did see puffs leaving the side just after liftoff but it was an umbilical i think.
    I've attached an aerial photo showing the aftermah. Looks like antares fell to one side of the pad and spared it a little!
    Its mad how little scrap is left of the rocket! Vapourised!

    Comparing it to previous launches, it all look standard enough with the steam or smoke coming off the side, if it had been midday and brighter might have been easier to see where failure started

    Very true. Were there any thermal imaging cameras in use i wonder? Remember one of the last shuttle launches where they filmed it simultaneously at different exposures and spliced them so all exposure levels were on the one film. Some level of detail!

    Not sure what cameras they had, they did seem to switch to infared/night mode once or twice after the crash if I remember right, but probably didn't have anything too fancy recording it

    some good spectator videos here, although very distant, some running away and ducking down for fear of debris

    relative to their size the walls of the tanks on a rocket are about a third the thickness as the ones on a soft drinks can , so there isn't a lot of material to begin with.

    An extreme example was this
    An Atlas rocket would collapse under its own weight if not kept pressurized, and had to have 5 psi (34 kPa) nitrogen in the tank even when not fuelled.

    Not only does aluminium melt at a far lower temperature than you'd expect in a burning rocket it also burns, the Shuttle's SSRB's used powdered aluminium as the main fuel.

    As an aside, check out Ascent - Commemorating Shuttle which has loads of info on the mind-boggling camera stuff involved in shuttle launches. There's also a bonus clips video going around too.

    Yes exactly a propulsion failure occurred in the first stage, before it fell back to the ground to cause more havoc it was commanded to terminate by the flight termination system.

    For anyone uninformed about the reason it blew up is because it was commanded to not because of a failure.
    As far as I am aware there are no reports yet to explain exactly what went wrong as there were no known issues prior to launch. there are reports of moderate damage to the launch pad and site fuel tanks

    for anyone interested who is not already aware of safety systems in place with regards to rocket malfunctions

    Looking back at the video it is hard (for me!) to tell how much before impact did it blow. Either way i'm amazed there wasnt more damage to the launch pad and ancillary equipment.

    Still gonna cost 20mil and a year to put right....apparently.

    Are these figures got at by billing $1000 for a screw and $10000 for a door? The pic don't look that bad.

    Interesting number there,
    Twenty one people have died in the name of science, either space vehicle testing, launch, or re-entry prior to landing.

    Would have said much higher myself for some reason.

    This incident alone was several times that.

    https://en.wikipedia.org/wiki/Nedelin_catastrophe

    Fingal County Council are certainly not competent to be making decisions about the most important piece of infrastructure on the island. They need to stick to badly designed cycle lanes and deciding on whether Mrs Murphy can have her kitchen extension.

    Such a PITA finding this thread:mad:

    Popcorn at the ready, this baby is being rolled out for another go on Dec3 with a 30 min launch window,

    Different Rocket this time, Antares last time, Atlas this time. Great Pic gallery timeline of the last few months here of them getting it ready.

    It's called an Atlas but has nothing in common with a real Atlas.

    +1
    Even delivered to Vandenberg on a Russian plane :pac:

    In fairness the second stage uses a good old American RL10 engine. And like a lot of other flight proven technology from the 1960's still hasn't been replaced by something better/cheaper/more reliable.

    Scrubbed for 24hrs

    5.33pm Eastern time for launch, weather forecast give 30% chance of favourable condition for launch

    always possible, but with the Atlas the chances are low, very low
