It takes about 4 minutes more rotation for the Sun to be in the same place as yesterday. Hence a solar day, or time from noon to noon, is 23h 56m + 4m = 24 ho ...

In many cases astronomical phenomena viewed from the planet Mars are the same or similar to those seen from Earth but sometimes (as with the view of Earth as an evening/morning star) they can be quite different. For example, because the atmosphere of Mars does not contain an ozone layer, it is also possible to make UV observations from the surface of Mars.
