vesper also means evening

In the Roman Catholic Church, vespers is/are a service held on Sundays or holy days that includes the office of vespers.

As far as I know, the service of Vespers is a prayer service and not a mass (at least in the Lutheran church, in which I am theologically trained). The OP is related to an Abendmesse, which points out that it includes the Mass.
