While it sounds like a bad April Fools' Day prank this is happening: A space station the size of a bus is falling out of the sky and parts of it that don't burn up in re-entry are expected to hit Earth on Sunday, April 1, give or take a few days. A map from Aerospace predicts the most likely spots for China's Tiangong-1 space lab to land include most of Maryland and northern Virginia, nearly all of Pennsylvania and New Jersey, and it's expected to fall to earth between March 30 and April 6, depending on which scientist you ask. And while the odds that someone is hit by space debris in Maryland are pretty low, it has happened at least one other time in the U.S.

Tiangong-1, China's first space station and an experimental space laboratory, was launched in September 2011. Initially, the disposal plan was to have a controlled re-entry for the station. People on the ground would control the craft's engines and significantly slow its descent. "Firing the engines would have been done at a specific moment so that it would reenter the atmosphere and substantially burn up over a large, unpopulated region of the South Pacific ocean," the European Space Agency said in a blog post. "Any surviving pieces would fall into the ocean, far from any populated areas."

And some pieces will probably make it through that fiery re-entry, though no one knows exactly where they'll end up. The organization Aerospace Corp. has produced a map of the most likely places the debris could land. Its analysis indicates the station will make reentry somewhere between 43 degrees North and 43 degrees South latitudes, which includes northern California and parts of Illinois, as well as parts of southern Europe, China and Japan.

Other states in the "high risk" areas include most of Maryland and parts of Nevada, Oregon, Idaho, Utah, Colorado, Wyoming, South Dakota, Nebraska, Kansas, Missouri, Iowa, Minnesota, Michigan, Ohio, West Virginia, Pennsylvania, New York, Boston, Connecticut, Rhode Island, Vermont and New Hampshire.

No one knows where #Tiangong1 will reenter, but we do know odds of it harming someone are vanishingly small. Our scientists calculate odds of you being hit by Tiangong-1 debris are ~1mil times smaller than odds of winning Powerball jackpot – even if you live in 'high risk' areas. pic.twitter.com/ic6hSl7WD6

— TheAerospaceCorp (@AerospaceCorp) March 13, 2018 It won't be possible to give a more exact location until hours before re-entry, but the odds you get hit by a piece of the space station are extraordinarily low: about 1 million times smaller than winning a Powerball jackpot — and that's if you live in one of the high-risk areas, Aerospace Corp. estimated.



The organization says the odds are less than 1 in 1 trillion. And the ESA estimates it's even smaller: 1 in 300 trillion. Andrew Abraham, a senior member of the technical staff at Aerospace Corp., tells NBC News the debris is more likely to fall into the ocean or a piece of uninhabited land.
