In the first version of the Tenno's navigational Starchart, Alert missions had a short description that would be listed after the mission location. This description was randomly selected from a list, depending on the mission type, and served to explain why the Tenno were performing the mission.
These descriptions were removed when the Starchart was updated to version 2.0 in Update 14, and Alerts thereafter were only identified by their location (barring exceptions such as Gift of the Lotus Alerts or miscellaneous, unique Alerts). Alert missions were largely removed from the game in Update 24.3 and replaced with Nightwave challenges.
Note: as with all removed content, this information is of dubious canonicity and may no longer apply as far as lore is concerned. Similar descriptions of random mission assignments can still be found in Sorties and Archon Hunts in the World State Window.
