Get To The Belt: Jump off the tallest building into the asteroid belt.
On the first moon, there is a lone hypershot target in the canyons. The hypershot target will disable a forcefield covering a cave that contains the titanium bolt further on in the canyon. To find the target, look at the 'map' and find your ship, its engines are pointing at the target, follow that line on the map roughly a quarter of the way around the moon. You won't be able to see the target itself but you'll be able to see a dark blue circle with a silver cross through it which is what the target is sitting on. Get to this point of the moon and look around, you'll see some platforms floating in lava, this is the way to the cave. Activate the target and jump across the platforms. You'll then see more lava in front of you with a pillar of rock in the middle. Run across the black rocks in the lava that run around the right hand side of the pillar and the cave with your titanium bolt will be right in front of you.
On the second moon, get to the first jump pad. Instead of going forward, go right in mid-air and land on the ledge to grab the bolt.
