Germany's defunct ROSAT satellite will fall back to Earth some time this week, but German space officials say the fall site is still a mystery. Re-entry is expected between Friday and Oct. 24.
"The time and location of re-entry cannot be predicted precisely," the German Aerospace Center (DLR) stated. It also noted that re-entry can be calculated only to within two days but certainty will grow as the date draws closer.
The scientists say that even a day before re-entry the estimate will only be accurate to within five hours.
