Planets/Areas
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
This is a very large quicksand planet with several pyramids, stone platforms, many tornadoes, and a few huge dark sand pits. On one side of the planet, there is a very tall tower with a waterfall of sand pouring down the side. Mario must scale this tower to get to the Power Star for the mission Soaring on the Desert Winds. There is also an underground tunnel with Piranha Plants, Thwomps, currents of sand that can force the player back, and a large boulder that can be destroyed by Fire Mario. This tunnel is the only way between the beginning and the tower.

Ring Planet
This planet is a small stone ring surrounded by four small platforms. Four boulders can be found rolling around the ring. On the underside of the largest platform is a Hungry Luma and a few Crystals with Coins and Star Bits. A Rainbow Star can be found on the underside of the middle platform, and a Life Mushroom can be found on the underside of a smaller platform. If the Hungry Luma is fed, it will transform into the Pyramid Planet.

Speedy Sand Planets
These three stone planets each consist of stone boulders connected by fast sand currents that move Mario when he stands in them. The first planet is shaped like a slightly curved tube, the second is a ring, and the third is a sphere. On the second planet, there are five blue Star Chips that Mario must collect in order to progress. There is a Warp Pipe on the surface of the third planet that leads to the interior and a shortcut to the Maze Planet.

Maze Planet
This planet is a disk of quicksand with a two-sided maze. One side is tan and the other is gray. This planet features tornadoes, Dry Bones, a Thwomp, and a reversible tower that must be used for the mission Blasting through the Sand and its Speed Run. This is also the planet on which the mission Purple Coins in the Desert takes place. Captain Toad and the Toad Brigade can be found scattered around this planet during the purple coin mission.

Disk Planets
There are two disk planets. One has a rising and sinking tower on one side and a sinking glass tower on the other side. The other disk has a rising and sinking tower with a Bullet Bill blaster on one side while the other side is barren with falling blocks.

Sand Tide Planet
This planet is a small planet with several cones on it. This planet has many Crabbers, a giant thorny flower, and several Coconuts. A stump with three coins above it is revealed when the sand lowers. There is another stump on this planet that when pounded, will cause music notes to appear. If all the music notes are collected, a Sling Star will appear taking the player to one of the disk planets. This is necessary to complete to get the hidden star, Bullet Bill on Your Back.

Pokey Planets
These are two small planets with a giant Pokey on the northern one and tons of Coconuts on the southern one. The player needs to defeat the giant Pokey by spinning to throw the coconuts found on the planet. Then, a Launch Star will appear, taking Mario to the next planet.

Pyramid Planets
There are two double-sided pyramid planets. One side is not accessible and not solid, while the other is. On the inside of the accessible side lies a maze of rising and falling sand where Mario must find five Silver Stars, which will make a Green Star appear. This planet can only be accessed after feeding the Hungry Luma. The player can raise or lower the sand by stepping on some green platforms found in the area. The player must collect all the Silver Stars without being crushed. Once all the Silver Stars are collected, most of the sand will drain out of the pyramid, and the Green Star will reveal itself.

Cacti Planets
There are large cacti that can be seen, but are not solid or accessible.

Trivia

 * The Dusty Dune Galaxy, as well as the Battlerock Galaxy, has the most Power Stars in the game, with a total of seven.
 * On the first speed planet, if the player backflips into the right place, they will be pulled down by gravity and into the sand that causes Mario to lose a life.
 * In the underground tunnel, it is possible to defeat the Piranha Plants that are hanging upside down by stepping on them. This can be done by jumping and aiming carefully for their necks.
 * If the player goes in first person view on a certain spot on the sinking tower planet, the player can see a Launch Star hovering between two pyramids. It can only be used by a flying hack. If the player does use it, it will lead back to the sinking tower planet.
 * Along with Melty Molten Galaxy, this is the only galaxy to play the hurry theme in a non-comet mission.
