Bubonic plague case reported in China

Health officials in China reported that a man was infected with bubonic plague, the infectious disease that caused the Black Death.

  • The case was reported in the city of Bayannur, which has issued a level-three plague prevention warning.
  • Modern antibiotics can effectively treat bubonic plague, which spreads mainly by fleas.
  • Chinese health officials are also monitoring a newly discovered type of swine flu that has the potential to develop into a pandemic virus.

18-ton section of Chinese rocket crash lands following uncontrolled reentry

If you were awaiting screaming death from the skies, you can relax. For now.

  • China's Long March 5 rocket core has landed safely in the Atlantic Ocean following an uncontrolled entry.
  • Most of the time, returning hardware that doesn't burn up plunges into the ocean or uninhabited areas.
  • There have been two larger returnees in the past, though this one was quite big.

Maybe future generations will look back on these early days of space exploration and chuckle at what we had to suffer through. We live in a time when, every now and then, word goes out that some giant chunk of uncontrolled defunct space junk is about to crash down upon us somewhere, so, um, duck? The hope during such moments is that the deadly debris will land in the ocean that covers most of the Earth's surface or in some unpopulated area, and it usually does. Usually.

Anyhow, if you've been anxiously looking up this week — either at the sky or your ceiling in quarantine — waiting for the core section of China's Long March 5 (CZ-5B) rocket to end you, you can breathe a sigh of relief. It landed safely, for humans anyway, in the ocean off the west coast of Mauritania in northwest Africa on May 11.

Long March into the sea

Though CZ-5B is one of the largest craft to come down in an uncontrolled reentry, its size is not the only thing that had astronomers like Jonathan McDowell, of the Harvard-Smithsonian Center for Astrophysics, on the edge of their seats. "I've never seen a major reentry pass directly over so many major conurbations!" he tweeted. (A conurbation is an extended urban area.)

While some debris comes down via a controlled landing, that was not the plan for CZ-5B. McDowell tells CNN, "For a large object like this, dense pieces like parts of the rocket engines could survive reentry and crash to Earth." No biggie, he says, since, "Once they reach the lower atmosphere they are traveling relatively slowly, so worst case is they could take out a house."

CZ-5B took off just a week or so ago, on May 5 for just a few days in orbit. Some of its 30-meter-long core stage burned up on reentry, and apparently none of what remained hit anyone, but there are reports of property damage in the Côte d'Ivoire village of N'guinou.

We’ve ducked debris before

A no-doubt radioactive piece of Cosmos 954

At this point, there have been a number of well-publicized spacecraft plummeting down destination-unknown. Probably the scariest was the return of the 4.4-ton Soviet-era spy satellite Cosmos 954. What made its uncontrolled re-entry so frightening is that it was nuclear-powered and threatened to spew radioactive material all over wherever or whomever. The original plan had been to boost it high into a nuclear-safe orbit, but a separation failure doomed the craft to fall back to Earth.

In the end, Cosmos 954 did crash in Northwestern Canada, blowing radioactive debris over a wide area. Canada billed the U.S.S.R $6 million for the cleanup, of which only $3 million was eventually paid.

Probably the first widely publicized uncontrolled return, and one of the two most massive, was of Skylab in 1979. It was another case of a craft coming back earlier than intended, and though NASA couldn't control the 77-ton craft's reentry point, it could control the manner in which it tumbled on down. The nail-biting ended on July 11, 1979, when most of Skylab burned up over the Indian Ocean, though some big pieces survived the descent and landed southeast of Perth, Australia. No one got hurt. The Australian town of Esperance charged NASA $400 for littering. The U.S. also didn't pay up.

Another piece of debris larger than CZ-5B was the Soviet Salyut 7 after nine years in orbit. At the time it came down, it was docked with another spaceship, Cosmos 1686. Salyut 7 weighted in at about 22 tons, as did Cosmos 1686. The connected pair of craft reentered together, burning up and breaking apart over Argentina, with bits raining down on the town of Capitan Bermudez. Amazingly, no one was injured.

One could say we've been pretty lucky so far, though it's hard not to look forward to a time when dying spacecraft can be somehow vaporized out in space where it's safe instead putting those of us down here at absolutely-nothing-you-can-do-about-it risk.

Are we psychologically prepared for the coronavirus outbreak?

From travel restrictions to forced isolation, the new coronavirus brings psychological threats, too.

  • The novel coronavirus has spread to all continents except Antarctica, and it's infected more than 90,000 people as of early March.
  • In China, mental health officials are trying to keep up with thousands of service requests from doctors and civilians facing fear, anxiety and exhaustion.
  • It's unclear how Americans will react if the outbreak intensifies.

7 philosophers who were exiled from their societies

Being ahead of the curve can be a dangerous place. These 7 thinkers were driven from their homelands over it.

  • Many thinkers have been killed for their ideas. Some got away with exile.
  • Most of the ones we'll look at here were driven out by the government, but others fled for their own safety.
  • The fact that some of these thinkers are still famous centuries after their exile suggests they might have been on to something, even if their countrymen disagreed.

Flu kills 12,000 in 4 months. Is coronavirus panic overblown?

The CDC estimates that more than 210,000 people in the U.S. have been hospitalized by the flu this season.

  • The 2019-2020 flu season, which began in late September, is estimated to have already killed 12,000 to 30,000 people in the U.S., according to the CDC.
  • The death toll for the new strain of coronavirus remains far lower, prompting some people to argue that the public's concern about coronavirus is misplaced.
  • Still, there are valid reasons to be concerned about the new virus.
