"Activate launch pad" is an objective in The Void's Edge in Battleborn
Walkthrough
The team will need to head to the East from here. This will take you to the final portion of the mission. There, the group will need to stand on numerous pads to activate the launch pad that can send S1.Wolf into the Varelsi portal to shut it down.
The launcher will work to some degree, the problem is a Varelsi Conservator gets in the way and stops Wolf from being able to use the Launcher.
