One system. Every source.
The power management controller that lets one spacecraft run any mix of sources: solar, battery, radioisotope, and externally supplied power.
Spacecraft power sources don’t talk to each other.
Solar arrays, batteries, radioisotope generators, and externally supplied power each carry their own voltage, timing, and failure behavior. Most power systems today are wired for one source at a time.
That was tolerable when a spacecraft ran one source and a predictable load. It is not tolerable now. Payload demand is climbing, duty cycles are rising, and the set of available sources is widening faster than the systems meant to manage them. Each new source arrives as another bespoke integration, and the constraint moves from the source to the layer that is supposed to arbitrate between them.
One controller, every power source.
Source-agnostic arbitration
Coordinates solar, battery, radioisotope, and externally supplied power through a single control layer, so adding a source doesn’t mean re-engineering the bus.
Real-time load balancing
Continuously matches supply against subsystem demand, shifting priority as conditions change across an orbit or a mission phase.
A record you can verify
The controller keeps a record of how power was managed across a mission, in a form mission assurance can review rather than take on trust.
What this changes for your program.
Add a source without redesigning the bus
Aura is built so that introducing or changing a power source is an integration and configuration exercise, not a redesign of the power bus and not a new controller program.
Built to hand to your integration team
Your engineers get what they need to size and test the integration against your own vehicle, without needing access to our core.
Additive, never load-bearing
Aura’s supplemental capabilities are designed so that losing any one of them degrades the system to a defined safe state, and never takes the spacecraft’s baseline power management with it.
LEO constellations
Fleet-scale power management, where designing a controller per vehicle does not scale. One controller across the fleet, configured per mission.
Defense space
Programs that need a reviewable account of how power was managed, and a controller that degrades to a defined safe state under fault.
Source and service providers
If you build a power source or sell power as a service, Aura is the controller layer your customers integrate against. We do not build a competing source.
Three ways to start.
Review the architecture
We share a technical overview under NDA, written for engineers rather than for a pitch.
02Assess the integration
Under NDA, we give your team what it needs to size the work against your own vehicle.
03Talk to us about a pilot
Tell us about the mission and we will tell you plainly what is in scope today.
Aura Energy builds the control layer for spacecraft power. Our work is the software and system architecture that decides, in real time, how a spacecraft uses whatever power it has.
Why we started
Every spacecraft power system in service today was designed around the sources that vehicle happened to carry. That was a reasonable choice when a mission had one source and a predictable load. It stops being reasonable when a program wants to add a source, run a higher duty cycle, or field a hundred vehicles that ought to behave the same way.
The gap is not in the sources. New ways of generating and delivering power in space are reaching the market steadily. The gap is in the layer above them, which is still rebuilt from scratch for every vehicle. Aura exists to make that layer a product rather than a program cost.
Leadership
Rick Gruenhagen, Founder and CEO
Rick has spent about thirty years in software and connected hardware, including chief technology roles through three company exits with a combined value above $2.2 billion, among them Innovyze, acquired by Autodesk. At Spireon he was chief technology officer through the design and production of the company’s own embedded devices, shipped at volume into fleet, trailer, and automotive electrical environments. He served as a Naval Flight Officer and as Assistant Professor of Naval Science at MIT, and holds an MS in Computer Systems Engineering from Boston University. He wrote Aura’s patent and its product architecture, and his job now is building the team to execute on it.
Aura is founder-led and hiring. If you have taken a power or control system from architecture to working hardware and want to do it again on a small team, we would like to hear from you.
The company
Aura Energy LLC is a United States company, based in Orange County, California.

Privacy policy
Effective 24 August 2026
Aura Energy LLC ("Aura", "we") operates auraenergy.space. Aura is a Delaware limited liability company with its principal place of business in San Clemente, CA. This policy explains what the site collects, why, and what you can ask us to do about it. Questions go to info@auraenergy.space.
1. What we collect
1.1 Information you give us. If you use the contact form or email us, we receive your name, email address, organization, and whatever you write in the message. Send only what you want us to have; see our Terms of Use before sending anything technical or confidential.
1.2 Information collected automatically. Our hosting provider records standard server logs: IP address, browser and device type, pages requested, referring page, and timestamps. These are used for security and troubleshooting and are retained for [30] days.
1.3 Analytics. This site uses Vercel Analytics to count page views and understand which pages are read. Vercel Analytics sets no cookies and receives page URL, referrer, and coarse device and country information derived from the request. We do not use advertising or cross-site tracking tags.
1.4 What we do not collect. The site has no user accounts and no login. We do not take payment information. We do not knowingly collect sensitive personal information.
2. Why we use it
To respond to your inquiry and continue the conversation, to keep the site secure and working, and to understand which pages are read. Nothing else.
3. We do not sell your information
Aura does not sell personal information and does not share personal information for cross-context behavioral advertising, as those terms are used in California law. We have never done so.
4. Who else handles it
Our hosting provider, our email provider, and our analytics provider process this information on our instructions and for no purpose of their own. We also disclose information if required by law, or to protect the rights or safety of Aura or others.
5. How long we keep it
Contact submissions are kept while we are in contact with you and for [24] months afterward, then deleted. Server logs are kept for [30] days. Ask us to delete sooner and we will, unless we are required to keep it.

You may ask us to tell you what we hold about you, correct it, or delete it. Email info@auraenergy.space with the request and we will respond within [45] days. There is no charge and we will not treat you differently for asking.
7. Do Not Track
California law requires us to say how we treat Do Not Track browser signals. This site does not respond to Do Not Track signals, because no common industry standard for interpreting them exists. We do not track visitors across other sites in any case.
