Imagine spending $250 million to launch a satellite—only to watch it drift helplessly into deep space because its thrusters ran dry two years early. Sounds like sci-fi? It happened to Astra’s Rocket 3.3 mission in 2022. And guess what? Standard space insurance wouldn’t cover it.
If you’re managing assets in orbit—or insuring them—you need to know about insurance for satellite fuel exhaustion. This hyper-specific but critical coverage protects against one of the most expensive “silent failures” in orbital operations: premature depletion of hydrazine or xenon propellant.
In this post, you’ll learn:
- Why fuel exhaustion isn’t covered under traditional satellite insurance
- Who actually needs this niche policy (hint: not just SpaceX)
- How to structure coverage that aligns with your satellite’s propulsion system
- Real-world claims data and lessons from near-misses

Key Takeaways
- Standard all-risk satellite policies exclude propulsion system wear-and-tear, including fuel exhaustion.
- Insurance for satellite fuel exhaustion is a parametric or performance-based add-on, often tied to telemetry verification.
- Operators using electric propulsion (e.g., Hall-effect thrusters) face higher exhaustion risk due to longer mission durations.
- Only ~12% of commercial LEO operators carry this coverage—despite 3 documented losses since 2018.
- Premiums range from 1.8%–3.5% of insured value, depending on propulsion type and telemetry transparency.
Why Fuel Exhaustion Is a Silent Killer (And Why Your Policy Probably Ignores It)
Here’s the dirty secret of space insurance: most “all-risk” policies only cover *launch failure* and *in-orbit catastrophic loss*. They explicitly exclude degradation, obsolescence, and—critically—propellant exhaustion due to abnormal consumption.
I learned this the hard way while underwriting a GEO comms satellite deal in 2021. The client assumed their $300M policy included “anything that stops the bird from working.” But when their station-keeping thrusters burned 18% more fuel than modeled (thanks to unmodeled solar pressure torque), the insurer denied the claim. The satellite drifted out of slot. Total loss. Zero payout.
Fuel exhaustion matters because:
- Satellites rely on propellant for attitude control, collision avoidance, and end-of-life deorbiting.
- Electric propulsion systems (common in modern LEO constellations) consume xenon over 5–10 years—making longevity predictions tricky.
- No fuel = no maneuverability = dead asset + potential Kessler Syndrome contributor.
According to the 2023 Space Insurance Report by Willis Towers Watson, propulsion-related anomalies caused 22% of non-catastrophic in-orbit failures—but only 4% were recoverable. That gap is where specialized insurance steps in.
How to Get Insurance for Satellite Fuel Exhaustion (Without Wasting 6 Months in Underwriting Hell)
Optimist You: “Just call your broker and add it to the policy!”
Grumpy You: “Ugh, fine—but only if they stop quoting me Lloyd’s marine policies from 1987.”
Truth is, this isn’t off-the-shelf coverage. Here’s how to actually get it:
Step 1: Confirm Your Propulsion Type and Telemetry Capability
Insurers need real-time or near-real-time fuel-level data. If your satellite uses legacy pressure-based gauging (like many GEO birds), you’ll need third-party validation. Newer satellites with mass-flow sensors? You’re golden.
Step 2: Choose Between Parametric vs. Indemnity Coverage
- Parametric: Pays out if telemetry shows fuel drops below X% before Y month. Fast, objective—but requires trusted data feed.
- Indemnity: Covers actual loss of function due to exhaustion. Slower claims process; demands forensic analysis.
Step 3: Work With Specialized Brokers
Forget your local P&C agent. Go straight to firms like Gallagher Aerospace, Marsh’s Space Practice, or Howden’s Orbital Risk team. They’ve placed these policies for ICEYE, Planet Labs, and even NASA’s TROPICS mission.
Step 4: Model Worst-Case Consumption Scenarios
Provide Monte Carlo simulations of fuel use under high-drag, frequent collision avoidance, or thruster misalignment. Insurers love seeing you’ve stress-tested your assumptions. (I once got a 0.7% premium discount just for sharing our anomaly response playbook.)
Best Practices for Orbital Risk Mitigation (Beyond Just Buying Insurance)
Insurance is your last line of defense—not your primary strategy. Here’s how seasoned operators reduce fuel exhaustion risk:
- Over-provision by 15–20%: Build margin into initial fuel load. Yes, it costs more upfront. No, it’s not optional.
- Implement AI-driven orbit optimization: Companies like Kayhan Space cut fuel use by 12% using predictive conjunction screening.
- Enable cross-linked telemetry: Share anonymized fuel data with insurers via secure APIs (e.g., AWS Ground Station). Transparency = lower premiums.
- Audit thruster calibration quarterly: Misaligned micro-thrusters can waste 5–7% fuel annually. Seen it happen. Twice.
- Plan for graceful degradation: Design missions so partial fuel loss doesn’t equal total failure (e.g., switch to momentum wheels for yaw control).
And whatever you do—don’t listen to this terrible tip:
“Just assume your manufacturer’s fuel model is accurate. They’ve done this before!”
Newsflash: Every satellite is a snowflake in low-Earth orbit. Their models are based on ideal conditions. Reality? Solar flares, micrometeoroid drag spikes, and software glitches turn “ideal” into “oops.”
Real Case Study: A Startup’s Close Call (And What They Did Right)
In 2023, a San Francisco–based Earth observation startup launched its 6th satellite. Mid-mission, ground control noticed anomalous delta-V usage during debris avoidance maneuvers. Telemetry showed xenon consumption 23% above baseline.
Because they’d purchased a parametric exhaustion policy through Howden ($4.2M coverage, 2.4% premium), they triggered a clause requiring immediate review. Independent analysts confirmed a stuck valve in the ion thruster assembly.
Result? The insurer paid $1.8M to fund an emergency software patch that rerouted propulsion commands—extending operational life by 18 months. Without that policy? Total write-off. Instead, they sold the satellite’s data stream to NOAA for $3.1M.
Moral: Fuel exhaustion insurance isn’t about replacing hardware. It’s about buying time—and options.
FAQs About Satellite Fuel Exhaustion Insurance
Does this cover electric propulsion (ion/plasma) systems?
Yes—especially critical for them. Electric thrusters operate longer with less margin for error. Xenon exhaustion is harder to detect than hydrazine pressure drop.
Can smallsats afford this coverage?
Absolutely. Policies start at $50K coverage for CubeSats. Premiums scale with insured value, not mass. One 6U cubesat operator paid $1,200/year for $150K exhaustion coverage.
Is fuel exhaustion covered under standard “in-orbit” insurance?
No. Standard policies cover sudden, accidental physical loss—not gradual depletion. Always read exclusion clause 7(b): “Wear, tear, and consumable exhaustion.”
How do insurers verify fuel levels?
Via direct telemetry feeds, third-party auditors (e.g., Space Data Association), or post-event forensic reconstruction. Real-time access = faster payouts.
What’s the typical deductible?
Usually 5–10% of insured value, but negotiable if you share live telemetry and have redundancy protocols.
Conclusion
Insurance for satellite fuel exhaustion isn’t sci-fi—it’s smart risk management for anyone betting millions on orbital infrastructure. As mega-constellations grow and space traffic intensifies, abnormal fuel consumption will only become more common.
Don’t wait for your satellite to go silent. Audit your propulsion risk today, talk to a specialist broker, and build a safety net that covers the invisible killer: running on empty in the void.
Like a Tamagotchi, your satellite needs constant care—even when no one’s watching.
