Walk towards your left until you find a shiny module, revealing bricks for a rotator switch once you blow it up with a thermal detonator. Build the rotator switch and push it, which will push the huge metal tower to your right more upright. When this is done bricks will fall down that you can use to build a grapple point. Build it, and grapple up to find Luke near the top of the tower.
