NASA is preparing an unusual mission to save one of its most productive observatories before it runs out of time. The NASA satellite Neil Gehrels Swift Observatory, which was launched in 2004, has come down from its orbit of 600 kilometres to a mere 370 kilometres, thus making the satellite vulnerable to re-entry into the earth’s atmosphere even before 2026.

According to scientists, the loss of such a vital satellite would create a large void in the research on violent events that take place in space.
