China Confirms Its Space Station Is Falling Back to Earth (popularmechanics.com)

The Tiangong-1, China's prototype space station which was launched in September 2011, is no longer under the control of China. PopularMechanics reports: China's Tiangong-1 space station has been orbiting the planet for about 5 years now, but recently it was decommissioned and the Chinese astronauts returned to the surface. In a press conference, China announced that the space station would be falling back to earth at some point in late 2017. Normally, a decommissioned satellite or space station would be retired by forcing it to burn up in the atmosphere. This type of burn is controlled, and most satellite re-entries are scheduled to burn up over the ocean to avoid endangering people. However, it seems that China's space agency is not sure exactly when Tiangong-1 will re-enter the atmosphere, which implies that the station has been damaged somehow and China is no longer able to control it. This is important because it means Tiangong-1 won't be able to burn up in a controlled manner. All we know is it will burn up at some point in late 2017, but it is impossible to predict exactly when or where. This means that there is a chance debris from the falling spacecraft could strike a populated area.

    The Day Skylab Crashed to Earth: Facts About the First U.S. Space Station’s Re-Entry
    July 11, 2012 By Elizabeth Hanes

    On July 11, 1979, the world watched as Skylab, America’s first manned space station, hurtled toward Earth. With the massive orbiter nearing re-entry, reactions on the ground ranged from fear to celebration to commercial opportunism. On the 33rd anniversary of Skylab’s fiery return to terra firma, find out more about the causes and fallout of the crash, as well as how NASA scrambled to cope with it.

    1. Skylab was made to go up but not to come back down.
    The space station known as Skylab was designed as an orbiting workshop for research on scientific matters, such as the effects of prolonged weightlessness on the human body. Because the project represented the next step toward wider space exploration, NASA threw itself into successfully putting Skylab in orbit. Unfortunately, the agency spent far less time and energy planning how to gracefully bring the space station back to Earth at the end of its mission. Even though Skylab was devised for just a nine-year lifespan, NASA failed to build in any control or navigation mechanisms to return the orbiter to terra firma. Doing so would have “cost too much,” administrator Robert Frosch said at the time. This lack of preparation presented a problem in late 1978, when NASA engineers discovered the station’s orbit was decaying rapidly. Skylab had become a 77-ton loose cannon. As word spread of the impending uncontrolled crash of the space station, Congress and the public demanded to know how NASA intended to avoid human casualties from the potential disaster. NASA responded with a plan to rehabilitate the laboratory-in-the-sky. The agency would use a new tool in development—the space shuttle—to boost Skylab into a higher orbit, thereby extending the lab’s operational life by about five years. After that, the station would simply continue to orbit as a shell, like the millions of tons of floating detritus now known as space junk. Funding and other snafus delayed the shuttle project, however, so NASA had to come up with a new plan. On July 11, 1979, with Skylab rapidly descending from orbit, engineers fired the station’s booster rockets, sending it into a tumble they hoped would bring it down in the Indian Ocean. They were close. While large chunks did go into the ocean, parts of the space station also littered populated areas of western Australia. Fortunately, no one was injured.

    2. In June 1979, as the crash approached, Skylab-inspired parties and products were all the rage in the United States.
    The imminent crash of Skylab midway through 1979 coincided with Americans’ declining confidence in their government. The stagnant economy and a second oil crisis dropped Congress’ approval rating to just 19 percent that year. Perhaps it’s no surprise, then, that many people took an irreverent view of the demise of Skylab, a government project. The Associated Press reported several instances of “Skylab parties” occurring across the United States. In St. Louis, Missouri, the “Skylab Watchers and Gourmet Diners Society” announced plans to view Skylab’s last orbit during a garden gathering at which “hard hats or similar protective headgear” were required. The Charlotte, North Carolina, News-Observer reported that a local hotel designated itself an “official Skylab crash zone (complete with painted target)” and was holding a poolside disco party. Mocking NASA’s inability to say precisely where Skylab would land, entrepreneurs across the country sold T-shirts emblazoned with large bullseyes. Another enterprising individual took a different tack and sold cans of “Skylab repellent.”

    3. In Europe and Asia, fear of Skylab’s re-entry prompted unusual safety measures.

  3. China didn't announce losing control of Tiangong-1 by Anonymous Coward · · Score: 2, Informative

    Where did Avery Thompson got the idea that China has lost control of Tiangong-1?

    Quote from his article: http://www.popularmechanics.com/space/satellites/a22936/tiangong-falling-to-earth/,

    "In a press conference on Wednesday, Chinese officials appear to have confirmed what many observers have long suspected: that China is no longer in control of its space station."

    That "press conference" he referred to as his proof, says exactly the opposite, http://news.xinhuanet.com/english/2016-09/14/c_135687885.htm,

    ""Based on our calculation and analysis, most parts of the space lab will burn up during falling," she said, adding that it was unlikely to affect aviation activities or cause damage to the ground.

    China has always highly valued the management of space debris, conducting research and tests on space debris mitigation and cleaning, Wu said.

    Now, China will continue to monitor Tiangong-1 and strengthen early warning for possible collision with objects. If necessary, China will release a forecast of its falling and report it internationally, said Wu."

    Skylab fell on my defenceless homeland. On News at Ten (ITN), Reginald Bosanquet, overcome with disbelief, read his autocue one line at a time. ‘Skylab broke up, with debris. Streaking across the night sky and heading. Thousands of miles across the. Ocean for Australia.’

    At least Reggie wasn’t entirely speechless. I’m bound to confess that I was, since until that point I had been an admirer of President Carter. But when they start strafing your own country with tons of red-hot supersonic junk you can’t help wondering whether there might not be some substance in all those theories about US imperialism.

    No kidding. Chinese government confirmed (yet again) for not valuing human life overly much.

    The US and Russia have both had plenty of satellites re-enter the atmosphere completely uncontrolled. If you are going to throw shade at least don't be a hypocrite while you do it. If the thing malfunctioned then this is exactly the expected final result.

    If the damned thing strikes in a populated area and people die, I say they drag them into The Hauge for a crime against humanity.

    Got any other impotent rage you'd like to get out?
