Keeping Moon Dust Where It Belongs: Smarter Vacuum Control for Lunar Research
If there’s one thing space researchers know, it’s that lunar regolith – or moon dust – is a troublemaker. It’s abrasive, clingy, and if it gets sucked into a vacuum pump, it can shorten the pump’s lifespan and ruin precious experimental samples.
That’s the challenge DigiVac set out to solve: create a vacuum system that can evacuate a chamber without sending fine regolith particles swirling into the hardware.
The Problem
Simulated lunar research often involves delicate materials that need a precise environment. Traditional high-vacuum setups can pull air out too quickly, disturbing the regolith bed and contaminating both pump and experiment. On top of that, many labs have limited space, so the solution had to be compact and mobile.
The Solution: Gentle, Automated Control
The result was a mobile vacuum cart powered by DigiVac’s SNAP Vacuum Controller – a system that can:
- Slowly evacuate chambers to prevent particle movement
- Automatically transition to high vacuum without manual valve juggling
- Use custom “recipes” with up to 24 steps for precise ramp-and-hold profiles
- Allow push-button commands like Full Vac and Vent for simplified operation
The SNAP controller’s patented valve technology enables smooth, controlled evacuation. Scientists can set flow rates and vacuum thresholds tailored to their experiments, then let the automation do the work.
Testing the Tech
The system was put through continuous evacuation–purge cycles to mimic the client’s lunar environment tests. One key tweak was adding hysteresis – a timing delay before exposing the turbomolecular pump – to ensure safe operation, especially with larger chambers.
The result? Hundreds of hours of uninterrupted, clean operation, all without disturbing the regolith bed.
Why It Matters
By combining precise control, automation, and mobility, this system:
- Protects sensitive materials from unwanted disturbance
- Saves researchers time and effort
- Fits neatly into tight lab spaces
- Supports long-duration experiments without constant supervision
The Bigger Picture
Lunar research is moving toward In-Situ Resource Utilization (ISRU) – using local materials for construction, fuel, and more. Understanding how regolith behaves in vacuum is critical, and having a system that can handle that delicately is a big win for space science.
With this mobile vacuum cart, researchers can focus on their experiments, not their pumps, and keep moon dust exactly where it belongs.
