China's Rocket Fails After Liftoff (cnn.com)

An anonymous reader quotes CNN: The second launch of China's new-generation Long March-5 carrier rocket failed Sunday -- dealing a blow to the country's ambitious space aspirations. Carrying an experimental communications satellite, China's largest rocket lifted off at 7:23 p.m. local time (7:23 a.m. ET) toward clear skies from the seaside Wenchang space launch center on the southern Chinese island of Hainan. But 40 minutes later, the state-run Xinhua news agency flashed a headline declaring the launch a failure -- without providing any details.

Dubbed "Chubby 5" for its huge size -- 5 meters in diameter and 57 meters tall -- the LM-5 rocket is designed to carry up to 25 tons of payload into low orbit, more than doubling the country's previous lift capability... The launch failure means further delay for a series of planned Chinese space endeavors -- including its robotic and eventual human lunar programs -- according to Joan Johnson-Freese, a professor at the US Naval War College and an expert on China's space program... China has announced plans to land a robotic probe on the dark side of the moon later this year and to reach Mars around 2020. All such future missions will depend on the LM-5 and space officials told reporters Sunday that the latest launch would help perfect the rocket design, including enabling it to send a space station into orbit "in a year or two."

This morning Elon Musk tweeted his condolences, adding "I know how painful that is to the people who designed & built it."

      No. The whole moon has been photographed in about comparable detail.

      'Dark' is just wrong. You could make an argument for 'radio dark', but that's even more unclear. There is a dark side of the moon, just as there is a dark side of the earth. They just move.

      You'd think that CNN would be making extra efforts, right now, to not be clowns...'far side', it's not complicated.

    I assume the malfunction failed to get it into the correct orbital profile, since the limited videos available all look okay? (no kaboom) Or does someone have a more informative video?

      There's some reasonable, in-depth analysis on the failure here: https://forum.nasaspaceflight.com/index.php?topic=42798.200. Be warned, if you like rockets and spaceflight, going to that site will cost you time.

      Summary: The first stage/boosters failed to generate enough thrust to achieve the proper staging point, as shown by the planned plot on the broadcast and the actual track. Some speculation points at a failure of one the boosters during the initial flight phase (before the boosters separate). The second stage separated and fired considerably later than planned and at some point, the mission was declared to be unsuccessful, due to flight anomalies.

      Politics aside, please note that the open broadcast of the launch is what enables this informed discussion, and for that, us space geeks can appreciate the access granted by the Chinese Space Agency to the live broadcast.

      Opinion: this was not helpful for the Chinese launch program, but at least the vehicle didn't RUD (rapid unplanned disassembly). Analysis of the telemetry will assist them in determining the cause, and may help them to engineer a fix. It's still a setback to their heavy lift ambitions for this year.

    Only Stalin's Russia was so harsh as to demand gulag time for a rocket failure. (And to his credit, Korolev took the full blame, knowing he was indispensable)

    I'm not even convinced Norh Korea would be so shortsighted as to send a rocket scientist to a salt mine over a launch failure.

    China definitely wouldn't... they save that for dissidents

    Korolev himself was sent to work in a platinum mine where he lost his teeth when he was younger. If it wasn't for Tupolev getting him out, to work in his prison lab, he would quite likely have died there in the mines. Korolev was interested in rocket powered airplanes when he was younger. Those back then were considered to have limited applications, so he was basically sentenced for misusing state resources or something like that.

    The CZ-5 uses LOX/Kerosene in the first stage. AFAIK most older Chinese rockets use liquid hypergolic propellants in the first stages. With the exception of Long March 3 and KT-1 which use solids.

    ROTFLMAO, this from a country that has about 1% of its adult population in prison. You have the highest prison population (per 100,000) in the world.
    Worse, is those prisons are often work camps, you either work making stuff that makes the owners money or you go to solitary.

    You have children sent to Juvi for disrupting class.

    Never mind all the "back ops" sites where you can detain people without charge , with access to lawyers, etc etc indefinitely.

      Just because it's a national broadcasting company doesn't mean it's state-run. You say "state run" when you're referring to the Chinese news in this case because the government gets editorial power. That's nothing at all like the BBC.

      Classic nonsense from the ignorant. The BBC is not state funded. It has a Royal Charter to operate and is funded by a license fee which is collected entirely separate from taxes. That is it goes nowhere near the general consolidated fund and if you dont known what that is you don't know what you are talking about. Her Majesty's government only gets involved in renewing the Royal Charter and in setting the licence fee. It is neither state run or state funded, with every government in my living memory complaing it is biased against them, which is a pretty good indication to me that it's not actually biased at all.
