MadSci Network: Astronomy |
Hi Jayne,
This problem was solved long before the advent of space travel. Railroads,
shipping lines, and airlines all need a standard timezone to keep their
schedules understandable. The time used by nearly all astronomers (and
NASA, and just about everyone else involved in space) is Greenwich Mean Time
(GMT),
which was originally based on the time at the Greenwich Observatory in
England. Nearly all astronomical observatories and space facilities keep
their schedules in GMT, and events are logged in GMT (also called Universal
Time, or UT).
You can read more about GMT at

and you can read more about the space station at

If you want to talk about this some more, you can reach me via the Mad
Scientist Network or directly by email at
