The Neil Gehrels Swift Observatory space telescope entered the atmosphere on Wednesday, after about 22 years in space. Among other things, the satellite observed short gamma-ray bursts and helped astronomers study such cosmic explosions quickly.
According to NASA, Swift re-entered the atmosphere over North Sumatra on Wednesday. The satellite weighed about 1.5 tonnes; it has not yet been established what proportion of it burned up completely or whether debris reached the Earth's surface.
Swift was launched in 2004 and was designed to detect short-duration gamma-ray bursts. Such bursts are among the most powerful explosions in the universe. After receiving an alert, the telescope could quickly change direction and have the source examined with other instruments.
According to NASA, the mission produced observations of thousands of cosmic sources. The data helped researchers, among other things, study the birth of black holes, collisions between compact stars and the evolution of galaxies.
The satellite stopped carrying out scientific work earlier this year. Its return became inevitable as its orbital altitude declined. An attempt to keep Swift in a higher orbit for longer was not carried out in time, meaning the telescope eventually descended through the atmosphere on its own.
A re-entry such as this does not automatically mean that all components reach the ground. Intense heating occurs as an object enters the atmosphere, but some components can survive the descent. NASA and independent satellite trackers could therefore estimate the orbit and timing of the re-entry, but could not specify in advance exactly where any debris might fall.
Swift was not a crewed mission, and there have been no reports of damage or casualties. The re-entry mainly marks the end of a long-running observation mission; the collected measurement data remain available for further research.
