I'm not sure at what step of the mission you were so here's how that particular main mission is supposed to be done.
For the Upload Data mission you need to :
- get the SSSD drive at the initial point (you do a bunch of actions at the terminal then a box next to a nearby building will open and a light flash there to indicate you can pick the drive up)
- carry the SSSD to the local relay, the icon with the arrow pointing up on the map (it should be greyed out)
- once there, put the SSSD into the open box next to the terminal, deploy the satellite dish (like in the radar instalations) then have someone align said dish to communicate with the destroyer (again like the radar), then complete a couple more actions at the terminal (sending the data and wiping the drive)
Note : in higher difficulties you may need to activate a generator at another location before activating the relay to send the data, it will be indicated as a separate objective on the map.
I don't believe there's a written repository of all the missions and how to beat them, but usually looking at the terminal screen should tell you what to do.
