Micrometeoroid & orbital debris risk

Cosmic grit can end a billion-dollar mission.

The Cosmic Lab tests, measures, and models hypervelocity impact risk — so satellites survive what's already out there.

Documented, not theoretical

Losses on record

A one-millimetre speck of cosmic grit travelling at 58.8 km/s The Perseid meteor shower peaks in mid-August, when Earth crosses the debris trail of comet 109P/Swift–Tuttle. Its meteoroids hit the atmosphere at roughly 58.8 km/s (≈131,500 mph) — among the fastest of any annual shower. carries the destructive energy of a 5.9 kg object hitting at 100 km/h (13 lb at 62 mph). Below are ten missions, spanning six decades, confirmed lost or degraded by particles smaller than that.

  1. 1967

    Mariner 4

    NASA · Mars flyby

    Flew through an intense micrometeoroid shower: 17 hits in 15 minutes on 15 September, then 83 hits on 10–11 December, causing attitude perturbations and thermal shield degradation.

    Slightly Damaged
  2. 1986

    Giotto

    ESA · Comet Halley flyby

    Severe dust impacts during closest approach to Comet Halley destroyed several instruments and permanently shifted the spacecraft's spin axis.

    Critically Damaged
  3. 1989–93

    Hipparcos

    ESA · Astrometry

    Over 100 cumulative micrometeoroid impacts caused step-wise attitude changes, requiring continuous thruster correction for years.

    Slightly Damaged
  4. 1993

    Olympus-1

    ESA · Communications

    A Perseid meteoroid struck near the electronics bay, triggering a plasma discharge and EMP that sent phantom commands into the attitude computer. The satellite spun out of control and was retired.

    Terminally Lost
  5. 2000

    IMAGE

    NASA · Magnetosphere imaging

    On 3 October 2000, one of the spacecraft's radio-antenna monopoles was partially severed, apparently by a micrometeoroid, modestly reducing the instrument's transmit power.

    Slightly Damaged
  6. 2005

    XMM-Newton

    ESA · X-ray observatory

    A micrometeoroid entered through the open mirror assembly and destroyed the CCD6 segment of the MOS1 camera, permanently reducing scientific throughput.

    Slightly Damaged
  7. 2009

    Landsat 5

    USGS · Earth observation

    Lost gyroscopic attitude control during the Perseid meteor shower after a plasma-induced electrical transient — not a mechanical failure.

    Slightly Damaged
  8. 2013

    BLITS

    Russia · Geodetic laser satellite

    A small meteoroid altered the satellite's orbital period, changed its spin rate, and ejected a trackable 10cm fragment.

    Critically Damaged
  9. 2022

    James Webb Space Telescope

    NASA / ESA / CSA · Infrared observatory

    A micrometeoroid struck mirror segment C3, raising its wavefront error from 56nm to 258nm rms — later mitigated to 178nm via micro-actuators, but the mark is permanent.

    Slightly Damaged
  10. 2024

    Gaia

    ESA · Astrometry

    An oblique micrometeoroid strike punctured the protective cover, letting stray sunlight leak onto the focal plane and trigger thousands of false star detections.

    Slightly Damaged

How often does it happen?

Drag the slider to set a particle radius and see how often something that size or larger hits one square metre of spacecraft, using the Grün model — the predecessor of our next-gen IMEM2 model.

Model: Grün, E., Zook, H.A., Fechtig, H., Giese, R.H. (1985), "Collisional Balance of the Meteoritic Complex," Icarus 62, 244–272. Assumes bulk particle density ρ = 2.5 g/cm³, cumulative flux onto a randomly-tumbling plate, unmodified by Earth shielding or gravitational focusing.

Hardware, testing & simulation

One stack, two ways in

Estimate your risk with our models. Then: qualify hardware on your own accelerator or rent time on ours.

Hardware & Accelerator-as-a-Service

Dust accelerators, built to order — or rented by the hour

We design and manufacture electrostatic dust accelerators and dust sources for labs that need in-house hypervelocity qualification — focus system, beam monitor, and particle selection unit included. Two accelerators are already in operation, covering complementary regimes from single hypervelocity impacts to high-flux shower testing, both firing metal (Fe, Ni, Al, Ag) and coated polymer or glass projectiles, in single-shot or continuous-beam mode. Don't want to own the hardware? With Accelerator-as-a-Service you can rent ours — the same test envelopes, no capital outlay.

Marketing schematic, not a live calculation — distances and orbits are not to scale.

Model-as-a-Service

IMEM2 & IMEX, in the cloud

Query the same micrometeoroid environment models developed for ESA-class missions — from low Earth orbit to interplanetary trajectories — without installing or compiling anything. One versioned, reproducible ground truth, reachable by UI or API.

Mass–velocity parameter space

Where our stack actually operates

The electrostatic accelerator and the IMEM2 model cover the same hypervelocity, sub-millimetre regime — against the natural dust populations and other accelerator technologies that surround it. Hover or focus a region to see what it is.
