  • MAJOR Proton rocket explosion (update)



    No flight termination charges, Russian launches don't usually use them. They just cut the engines, and here even that's questionable. They may have tried to get it further from the complex First major lower stage failure of Proton since the 80's, though one in '69 was nearly identical to this one.

    This may spur Congress to speed up the US commercial crew program as something is major broke in the Russian space program

    Russia's Proton crashes with a trio of navigation satellites

    2013 July 2

    Russia's Proton rocket crashed less than a minute after its liftoff from Baikonur, Kazakhstan, Monday.

    A Proton-M with a Block DM-03 upper stage lifted off as scheduled from Pad No. 24 at Site 81 in Baikonur Cosmodrome on July 2, 2013, at 06:38:22 Moscow Time (on July 1, 10:38 p.m. EDT).

    The rocket started veering off course right after leaving the pad, deviating from the vertical path in various directions and then plunged to the ground seconds later nose first. The payload section and the upper stage were sheered off the vehicle moments before it impacted the ground and exploded. The flight lasted no more than 30 seconds.

    The Russian space agency's ground processing and launch contractor, TsENKI, was broadcasting the launch live and captured the entire process of the vehicle's disintegration and its crash. Half an hour after the accident, a report on Russian web forums said that a team in the launch control bunker near the launch pad had been in communication with the rest of the space center and apparently had been unharmed. The launch vehicle reportedly crashed near another launch complex for Proton rockets at Site 200.

    Since the emergency cutoff of the first stage engines is blocked during the first 42 seconds of the flight to ensure that the rocket clears the launch complex, the vehicle continued flying with its propulsion system firing practically until the impact on the ground.

    Around an hour after the accident, a Russian Vesti 24 TV channel reported that Kazakh authorities had considered evacuating population from the area around the crash site due to a possible danger from toxic propellants onboard the rocket. The main residential area of Baikonur Cosmodrome is located 57 kilometers southeast of the Proton launch area.

    During the evacuation, some of the personnel at Baikonur took photos of a reddish cloud spanning over the main road to the facility. In Baikonur itself, the city's administration advised residents not to leave their homes, deactivate air conditioners and close tightly all doors and windows due to "a cloud of unburned propellant moving toward towns of Baikonur, Akai and Tyuratam." Fortunately, starting rain apparently helped to dissipate the cloud, Kazakh media reported.

    Is anyone actually surprised anymore when Russia blows up yet another rocket?

      Sadly, no. They act like it out of politeness, but not really. It just missed Proton Site 200, so it was a close call as far a losing other pads.

      Pravda is reporting a 200 meter crater.

        That was one wicked shockwave.

            It left a crater 200m across and sprayed 600 mT of unsymmetrical dimethylhydrazine and nitrogen tetroxide across the landscape. Baikanur will be shut down 2-3 months during the investigation & cleanup. Even with a successful launch locals lose cattle & other livestock to poisoning.

            As to the insurance, the Proton cost $100-140 million and the satellites another $200 million. Launch insurance usually bases at $15-20 million and goes up with the cost of the satellites, but with the number of failures they've had it'll be a lot more. Not even sure if they're even insuring Russian Federal launches anymore - might be cheaper to build spares of everything.

                WTF?!?



                Culprit found

                By July 9, it is transpired that investigators sifting through the wreckage of the doomed rocket had found critical angular velocity sensors, DUS, installed upside down. Each of those sensors had an arrow that was suppose to point toward the top of the vehicle, however multiple sensors on the failed rocket were pointing downward instead. As a result, the flight control system was receiving wrong information about the position of the rocket and tried to "correct" it, causing the vehicle to swing wildly and, ultimately, crash. The paper trail led to a young technician responsible for the wrong assembly of the hardware, but also raised serious issues of quality control at the Proton's manufacturing plant, at the rocket's testing facility and at the assembly building in Baikonur. It appeared that no visual control of the faulty installation had been conducted, while electrical checks had not detected the problem since all circuits had been working correctly.

                Implications

                It was the first time in the post-Soviet history that the Proton rocket, a largest vehicle in the current Russian rocket fleet, crashed in the vicinity of its launch facility. On April 2, 1969, a Proton rocket carrying a Mars probe crashed shortly after lifting off from the same Pad 24.

                Serious implications for the Russian space program and its rocket industry are practically inevitable, however there are no alternative to Proton until Angara becomes operational later in the decade at the earliest.

                Political fallout

                Shortly after the accident, Russian media reported that authorities started a criminal investigation in Baikonur under Chapter 1 of Article 216 of the Criminal Code entitled "Violations of safety rules during mining, construction and other works leading to a significant damage." Unofficial source at the site did confirm that criminal investigators had appeared at various facilities.

                Also, Russian Vice Prime-Minister Dmitry Rogozin promised to make "hard conclusions" from the investigation, which among other things "would identify those who despite numerous government requests failed to deal with many issues of quality control," Rogozin said. According to Rogozin, the failed vehicle had been manufactured and delivered to Baikonur before his administration restored the military certification of rocket technology.

                On July 8, Rogozin announced a formation of an expert engineering group, which would not include representatives of the Proton's contractors, but would be responsible for the review of the entire manufacturing process and quality control procedures during the production of the vehicle.

                  The Sept. 17 return to flight of Russia’s Proton rocket was postponed Sept. 11 for technical reasons associated with the Russian launch vehicle.

                  Marketed by International Launch Services (ILS) of Reston, Va., the commercial mission was slated to loft The EADS-Astrium-built Astra 2E satellite for fleet operator SES of Luxembourg.

                  “The launch date will be determined at a later time,” ILS said in a Sept. 12 statement.

                  Engineers at Proton prime contractor Khrunichev State Research and Production Space Center of Moscow received an out-of-tolerance reading in the first stage of the vehicle at its Baikonur launch site in Kazakhstan on Sept. 11, according to ILS.

                  “It was determined that further investigation is necessary, requiring the launch vehicle be returned to the processing hall for additional testing,” said ILS, which is majority-owned by Khrunichev. “The vehicle and satellite remain in a safe configuration at the launch site.”

                  The mission would mark the first Proton rocket to launch since a July 2 mishap during a Russian federal mission sent a Proton M/Block DM3 crashing to the ground seconds after launch carrying three Russian Glonass M navigation satellites.

                  The mishap, attributed to the incorrect placement of angular-rate sensors on the rocket’s first stage, has already delayed the Astra 2E nearly two months from a planned July 20 launch.
