Someone from the MRO project at JPL let us know about this upcoming documentary:

Starting next week, the Science Channel will begin airing an updated
version of the MRO documentary that it showed last year!

The first of six listed air times is 10 p.m. on Wednesday, May 9, but
I think it depends on your cable provider whether you need to do a
time-zone adjustment, so check your cable listings.
