    Delta 4 Heavy rocket with a US intelligence satellite was launched in Florida

    Delta 4 Heavy rocket launched in Florida carrying US intelligence satellite.

    It is considered the most powerful rocket used by US, it displays the satellite into orbit for the central control of the military and space exploration.

    In this start, which took place today at 20:51 Moscow time, I was supposed to occur more June 9 but was postponed due to weather conditions.

    As reported by "RIA Novosti", the machine can be used for listening and collecting intelligence.

    SpaceX launches satellites but fails to recover rocket

    SpaceX successfully launched two satellites into orbit on Wednesday, but failed in an attempt to land the first stage of its Falcon 9 rocket undamaged on a barge in the Atlantic.

    The rocket apparently malfunctioned some 330 feet (70 meters) off the ground and was in flames when it reached the platform on the powered barge—known as a drone ship—live images via a SpaceX webcast showed. SpaceX chief Elon Musk later confirmed the failure on Twitter.

    "Ascent phase & satellites look good, but booster rocket had a RUD on droneship," he wrote, using an acronym for "rapid unscheduled disassembly," or explosion.

    The rocket shook the barge when it landed, causing the ship's camera to freeze. The final images showed the craft standing upright, enveloped in flames and thick smoke. The rocket earlier successfully boosted into orbit a communications satellite for the French firm Eutelsat and another for Bermuda-based ABS.

    The launch from Florida's Cape Canaveral took place at 10:29 am (1429 GMT) and the satellites deployed around 30 minutes later.
    It was SpaceX's sixth launch of the year.Wednesday's failure ends a recent streak of landing successes. The California-based company has successfully landed the first stages of its Falcon 9 rockets three times—twice on water and once on land.

    Musk wants to revolutionize the launch industry by making rocket components reusable, much the same way as commercial airplanes.
    Expensive rocket parts are currently jettisoned into the ocean after each launch. SpaceX is next set to launch a cargo resupply mission to the International Space Station for NASA next month.

    Explosion rocks SpaceX launch site in Florida during test — AP

    Eyewitnesses reported that a cloud of dark smoke filled the overcast sky

    EW YORK, September 1. /TASS/. - An explosion has rocked the SpaceX launch site in Florida during a routine test firing of an unmanned rocket, the Associated Press reported on Thursday.

    The test was conducted in advance of an Israeli satellite launch planned for Saturday from Cape Canaveral Air Force Station.

    Eyewitnesses reported that a cloud of dark smoke filled the overcast sky.

    Florida Today news portal said quoting the local emergency management office that the blast was no threat to general public.

    Space-X launch pad explosion

    I have never seen such a failure mode before. It is as if the final stage rockets ignited while the rocket was still on the ground.

    Maybe Hollywood can use this actual footage for some Superman vs. Batman movie in the future instead of a cheesy edit of a
    Soyuz rocket explosion that never happened.

    Such a failure will be expensive.

    Not just exploding on the launchpad with the payload on board, but added to previous failures to recover the rocket after use will be putting enormous pressure on them.

    After all if you plan to be able to recover and reuse rockets and you can't because they are exploding on landing, or worse... exploding before launch with the expensive payload on board it becomes very very hard to make that money back.

    This will really screw up their business model if they can't sort this out.
