    [​IMG]

    Cygnus spaceship blew up during the launch at the US Wallops Flight Facility.

    Cygnus spaceship, which was supposed to deliver more than 2 tons of cargo to International Space Station (ISS). The launch was broadcasted on The National Aeronautics and Space Administration (NASA) website.

    The launch from Wallops Flight Facility with the use of the Antares rocket launcher was scheduled for Tuesday.

    NASA mission control center confirmed they have lost the spacecraft.

    According to the host of the launch broadcast, the rocket exploded six seconds after liftoff.

    At the moment a contingency teams are conducting all the necessary work securing the area at the site of explosion, with no casualties or injuries reported.

    If there has been no loss in lives, the loss can be recouped.

    I posted something similar in Science forum. Perhaps mods can merge.

    @W.G.Ewald

    Read on a report that the rocket, to cut costs, used motors made in Soviet Republic in the '60s. Not just a '60's design, but motors actually manufactured in the '60s and stored in some place in Siberia till recently.

    True?

    No, the motors made in the USSR are NK-33 engines made by Kuznetsov, which are heavily modified in the United States, and then, it is called AJ26. Got this from Wiki, but the original source from Spaceflight Now no longer exists.

    The rocket engine you are talking about (?) is the RD-180, or Rakyetnyi Dvigatel 180, or simply, Rocket Engine 180, made by NPO Energomash. Those are used in the Atlas family of rockets, and have been largely successful.

    Edit: RD-180 was not stored in Siberia. NK-33 was. Both were procured to cut costs. NK-33 was used in a Soviet rocket meant for the moon, and the rocket blew up.

    That is obviously misleading.

    NK-33 and AJ26 are not the same thing. They have common components.

    NASA should just let SpaceX do the launching.

    Failure is an essential part of the path to success. Considering no one died, I wouldn't make a big deal of it.

    It is better to have competition. That brings about the best.

    It'll help them save some money and they can focus and spend more on their research.

    A SPECIAL COMMISSION TO INVESTIGATE THE ANTARES CRASH

    An accident has occurred at the NASA spaceport. 6 seconds after its launching, the carrier rocket Antares exploded with the American cargo ship Cygnus on board. The ship was supposed to deliver to the ISS about 2 tons of cargo for the US segment of the station, including scientific equipment, oxygen and provisions.

    The explosion was witnessed by hundreds and thousands of people worldwide. Official website of the US National Aerospace Agency (NASA) was broadcasting the launch live. Immediately after take-off, the rocket caught fire and crashed. Fortunately, there were no casualties, but expensive equipment got destroyed and the accident has inflicted serious damage to the spaceport on the Wallops Island situated on the Atlantic Ocean.

    Judging by the video, problems may have arisen at the first stage of the rocket’s engine. The engine of Antares had passed all tests at the checking stage and no problems were reported, declared Frank Culbertson, vice president of the company-manufacturer Orbital Sciences.


    “We can presently judge only by the video which has been seen by all. The ascent of the rocket ceased, and after that, it can be said, a ripping of the first stage took place and then it fell on the ground. We do not have access to the complete data at present, but as soon as the opportunity arises, we will begin to restore events and start evaluating them”.

    A Special Commission, which will investigate the circumstances and causes of the rocket’s explosion, has already been formed. Reasons that caused the accident will be discussed on the 4th of November at a meeting between the heads of space agencies, including NASA and the Roscosmos – the Russian Space Agency.

    The engines installed on Antares are of Soviet design. They were created by the designer Nikolai Kuznetsov in the 70’s of the last century for the realization of the Soviet “lunar program”. When the program closed down, the engines were placed in a preserved stage. And in the 1990’s, utilization of the NC-33 was reconsidered and demonstrated to foreign specialists. The American company Aerojet bought 40 pieces, but decided to upgrade them to fit into their rockets. After serious alterations, the modified engines were named AJ-26. Between Aerojet and the American company Orbital Sciences, a contract was signed for the supply of 20 engines NK-33 / AJ-26, two of which were installed on the crashed Antares rocket. And, production of the first stage of the engines and fuel systems was done at the Ukrainian design bureau “Yuzhnoe” from the city of Dnepropetrovsk.

    The exploding of the Antares has placed the further transfer of commercialization of the US space program under question. After NASA abandoned reusable shuttles, identifying them as too expensive, space transportation was passed into private hands. The Antares carrier and the space-ship Cygnus were built by the company Orbital Sciences. Last year, it successfully completed the first test flight to the ISS, after which NASA signed a contract worth 1.9 billion dollars with this company to enable eight launches of the “truck-loads” for three years. The current launch was the fourth.

    As assured by the agency, accident of the “truck-loads” will not affect the work of the US segment of the ISS. The stockpile of food and water at the station is adequate. Of course, the astronauts were nevertheless upset: they were left without gifts from home and without the promised burgers with shrimps. But if launches of American cargo ships of NASA do not resume soon, the US will have to request Russia to facilitate this. The subsequent launch of the Russian ship “Progress” took place on Wednesday, 9 hours after the Antares crash.

    Technology is not Science, there is always a room for error. I don't think this news is important, NASA being a premier Space Exploration agency can recover from such small setbacks.

    Ofcourse, this is how we understand technology better.
