Summary

Kea Aerospace is a Christchurch, New Zealand-based company developing the Kea Atmos, a solar-powered, remotely piloted fixed-wing aircraft intended to fly in the stratosphere for months at a time collecting high-resolution aerial imagery. In February 2025 its Kea Atmos Mk1b prototype completed the company’s first stratospheric flight, reaching 56,284 feet — a notable milestone for a Southern Hemisphere HAPS developer working with a comparatively small team and funding base relative to larger Northern Hemisphere competitors.

Key Facts

  • Founded: 2018
  • HQ: Christchurch, New Zealand
  • Type: Private company
  • Status: Active — flight-testing technology demonstrator (Kea Atmos Mk1/Mk1b); Mk2 long-endurance variant in development
  • Key metrics: Kea Atmos Mk1 — 12.5 m wingspan, under 40 kg weight, designed for ~50,000 ft and up to 16 hours; February 2025 flight reached 56,284 ft (17,155 m) over 8 hours 20 minutes, covering 420 km. Planned Mk2 wingspan approximately 30 m (per company website; not yet flown).

What It Is / How It Works

The Kea Atmos is designed as an uncrewed, solar-powered fixed-wing aircraft that climbs from a short runway to stratospheric altitude — roughly 50,000 to 65,000 feet, above commercial air traffic, weather, and jet streams — where it can operate continuously, recharging its batteries by day to sustain flight through the night. Kea Aerospace describes the aircraft interchangeably as a High Altitude Platform (HAP), High Altitude Long Endurance (HALE) vehicle, High Altitude Platform Station (HAPS), High Altitude Pseudo-Satellite, or “atmosat.” The company’s stated goal is to build a fleet of these aircraft to provide frequent, high-resolution aerial imagery for applications including environmental monitoring, precision agriculture, maritime awareness, and disaster management, positioning the platform as a cheaper, higher-resolution alternative to both satellites and crewed aircraft.

Because the aircraft must be extremely lightweight to operate in the thin air of the stratosphere, it does not carry landing gear. Instead, Kea Aerospace launches the Kea Atmos from the back of a driving electric vehicle (an Audi e-tron Sportback was used for at least one 2023 test), which accelerates the aircraft to takeoff speed before release.

The company’s development path has moved through several aircraft generations: an X10 low-altitude electric demonstrator that flew 36 hours non-stop in February 2022 to prove perpetual-flight endurance concepts, followed by the Kea Atmos Mk1 (first flown March 2023, 12.5 m wingspan), and the Mk1b variant that achieved the company’s first stratospheric flight in February 2025. Kea Aerospace states it plans to follow with a larger Mk2 variant (roughly 30 m wingspan) intended for long-duration stratospheric flight, though as of this entry the Mk2 has not been reported flying.

Kea Aerospace has said it is collaborating with NASA’s Ames Research Center on image-processing algorithms for its aerial imagery pipeline, and was reportedly the second company admitted to New Zealand’s government Airspace Integration Trials Programme, according to Wikipedia’s sourcing — these specific claims were not independently confirmed against a primary NASA or government source in this review.

Notable Developments

  • February 2025: The Kea Atmos Mk1b completed the company’s first flight into the stratosphere, reaching an altitude of 56,284 feet (17,155 m) with a flight duration of 8 hours 20 minutes and a total distance of 420 km, taking off from the Tāwhaki National Aerospace Centre south of Banks Peninsula, near Christchurch.
  • March 2023: The Kea Atmos Mk1 completed its maiden flight; flight testing began building toward stratospheric altitude, with the company describing it as the first solar-powered stratospheric aircraft designed and built in the Southern Hemisphere. The launch vehicle for at least this test campaign was an electric Audi e-tron Sportback.
  • February 2022: Kea Aerospace’s X10 aircraft flew 36 hours non-stop at low altitude, an early proof of the company’s perpetual-flight power and control systems.
  • October 2022: The company flew a high-altitude balloon mission (carrying a soft-toy mascot, “Kelly the Kea”) to test equipment ahead of stratospheric aircraft trials.
