The official description names three things to sweep: moon dust, space junk, and meteor debris. Selling what you collect earns cash. That is the confirmed rule for all three.
What is not separated
| Question | Documented answer |
|---|---|
| Is each material in the game? | Yes. The official description names all three. |
| Does each one have its own sell price? | No separate prices are published. |
| Does meteor debris need its own tool? | No required tool is named. |
| Do they use different storage? | Not documented. The backpack and tank warnings are the storage signals on screen. |
| Where does meteor debris spawn? | Specific spawn points and timers are not documented. |
Upgrade text talks about dust capacity even though the store description includes junk and meteor debris. Do not invent a second inventory from that wording.
How to clean them with the tools that are named
The playthrough shows a Hand Brush, a Lunar Shovel with strike speed, sweep width, and power, and a Turbo Vac described as fast dust collection. None of those panels says it is required for junk or meteors only.
Robot and drone signs talk about collecting dust and selling at the base. They do not say the helpers ignore the other two materials.
A useful limit
If a guide promises a higher-paying crater for meteor debris, it is ahead of the sources. Crater names, unlock rules, and debris values by zone are not documented. Sell the mixed haul you already picked up, then check the backpack before you walk farther.
