Every space location in the game has a Kyber Comet in orbit and Mustafar is no different. Shoot it down to receive x5 Kyber Bricks.

Turn around when you land and you should see a satellite tower off the landing pad. Grapple to it using a hero-type character and the first Kyber Brick will be waiting.

Just next to the landing pad, you'll find the operations generator. You need to use the force to move four generators onto the circuit and unlock the brick. Two of the mini-generators are just lying clearly in the room. One of them is on the tall column near the entrance. Break the Lego furniture in the room to rebuild the last one. Once they're all in place, switch to an astromech to activate the terminal and retrieve your brick.

On top of the Klegger Corp Mining Facility, there'll be a tower to the right. You'll see a Kyber Brick locked in a chest on top of the tower. The button to unlock is on the floor below.

On the left side of the Mining Facility, there'll be a rocky wall with a bunch of spaces for nets. Switch to a scavenger character to glide over. Build a net launcher to fill the spaces and climb to the top where your brick will be waiting.

Next to the DLC-13 Droid bays, there'll be a tower with spaces for nets on the side. Switch to a scavenger again to craft a net launcher, fill the spaces, and reach the brick.

Also next to the DLC-13 Droid bays, you should see a room locked by a force field. Go to the far right corner of the roof to find the key to open the door. Stack three Lego blocks to reach the key and take it back to the force field to unlock it.

Inside the Mining Facility, you'll reach a central control room with several tables inside. It should be familiar to you from Anakin and Obi-Wan's final dual. Break all four of the tables to collect the brick.

Also in the Mining Facility, you should reach a brick behind a large force field. The terminal to deactivate the field is on the ceiling at the back of the room. Use the force to stack four bricks on top of each other. Climb up and use a hero character to activate the terminal.

In the Antenna Control Room, there'll be a giant flea on the far side blocking a Kyber Brick. Use the force to control it and move it out of the way. You can also send a small droid through a hole on the side of the room.

On the stairs up to the shooting range, you should be able to find a brick hovering mid-air through one of the gaps. Glide to it using a scavenger character.

On Kleggers shooting range, you'll find another brick locked in a chest. You need to shoot the four different targets scattered off of the roof to unlock it. The game has an auto-aim feature that locks onto these targets, so go in-and-out of aiming if you're having trouble spotting them.

From the shooting range, use a scavenger's glider on the left side of the roof. Glide on top of the gas extraction antenna and collect the brick up top.

Just below 'Refinery Rooftop', you'll find a set of leaking pipes. The gas means you'll need a droid to enter. Use the force to stack a group of blocks to the left. Then switch to a droid to climb up the blocks, jump onto the broken pipes and reach the brick at the end of this short platforming section.

On the far North-side of the map, you'll find the broken lava collector arm. There are three switches on the 'fingers' of this arm. Pressing the switches changes the pattern on top of them. Look up top to see the pattern you need to match, it will also be on the image on this table.

This next brick is in the searing gorge, just left of the collector arm. Reaching it involves a platforming challenge where you'll need to jump across various moving platforms, on top of a lava pit. If you do fall into the lava, you'll respawn on the last platform you were on, rather than starting at the beginning of the challenge. Simply take it slow; wait for the platforms to align and you shouldn't have too much trouble.

In the Lava Java Lounge, there'll be a Kyber Brick in the room to the right, behind a locked door. You can find the keys to the door in a silver vending machine on the far side of the room. Use a villain character's grenade to break it apart.

In the black sun chamber, you'll find an incomplete painting on the far side of the room. You'll need to find the three missing pieces and put the painting back together to retrieve the next Kyber Brick. One of the pieces is just sitting on the main table. Another one of the pieces is inside a gold container near the entrance. The last one is on the right-hand side wall behind an astromech terminal. Use the force to put the pieces in the right positions.

After exiting the black sun chamber, look immediately left. Follow the ledge of the building until you come across the next brick.

On the far East side of the map, you should find three tall structures. Use a hero-type character to grapple up the structure on the right. Then use a scavenger to glide to the middle one. The Kyber Brick will be there.

Follow the small pipes hanging off the side of the Mining Facility until you reach a lava waterfall - a lavafall? Once here, there'll be a ledge just off of the pipes with the brick on it.

After exiting the black sun chamber, go straight to find a brick trapped inside a large metal pipe. You need to fill it with lava to lift the brick up. There'll be two levers on the left and right you can use to initiate the flow of lava, but only the right one is active. Push the lever on the right until the pipes are connected. After that, break the Lego containers next to the lever to find a battery inside. Transfer the battery to the lever on the left to activate it and repeat your actions. Once both are done, switch to an astromech to grapple to the ledge behind, activate the terminal, and voila! The Kyber Brick is yours.

Inside the Mining Facility, you'll find a locked door. The NPC outside will mention that you need the password hiding in Tatooine's Judland Wastes. Travel to the Judland Wastes and find the password in the Jawa Village on the South-West side of the map. The password should be through a hole that a small droid can fit through. Once you have it, return to the locked door on Mustafar and enter the password into the terminal.
