China's Tiangong-1 space station isn't long for this orbit.
Also known by its English translation, "Heavenly Palace," the out-of-control station is heading back into the atmosphere sometime around April 1. We don't know exactly when or exactly where it will reenter, but space fans will have a chance to watch one of its last passages across the sky live via telescope.
The China National Space Administration launched Tiangong-1 in 2011, but lost command of it in 2016, which has led to a lot of uncertainty about its re-entry and whether pieces of it might reach the ground.
In case you're concerned about debris, the Virtual Telescope Project reminds us that the possibility of being struck by a chunk of the space station is extremely low.
"The personal probability of being hit by a piece of debris from the Tiangong-1 is actually 10 million times smaller than the yearly chance of being hit by lightning," the European Space Agency says.
