China's falling space station burned up last night just north of the Spacecraft Cemetery

Last night, China's Tinagong-1 space station, about the size of a school bus, burned up as it fell over the Pacific Ocean. The Fraunhofer Institute for High Frequency Physics and Radar Techniques captured this hot image as the satellite was just 270 kilometers (170 miles) above Earth's surface. Kenneth Chang writes in the New York Times:

The demise of the station, Tiangong-1, became apparent when radar stations no longer detected it passing overhead. There were no immediate reports of damage or injuries; the likelihood that pieces would land on someone was small, but not zero.

The station may have landed northwest of Tahiti, Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, said on Twitter. That location is north of the Spacecraft Cemetery, an isolated region in the Pacific Ocean where space debris has frequently landed.

For the past few weeks the fate of Tiangong-1 has provided some drama. The Chinese lost control of the spacecraft a couple of years ago and thus could not guide it to the middle of an ocean. Because of the drag of air molecules bouncing off Tiangong-1, the station’s altitude dropped, and the descent accelerated quickly in the last few days.
