The reason VLEO has remained "Earth's last empty orbit" comes down to three relentless physical forces that attack any object that tries to fly there .
Aerodynamic drag is the most immediate threat. At altitudes of 200–300 km, residual atmosphere is still thick enough to act as a brake. Without a continuous counter-push, drag decelerates a satellite so fast it spirals back into the atmosphere and burns up in a matter of weeks, not years .
Atomic oxygen presents a chemical nightmare. In the upper atmosphere, ultraviolet radiation splits standard O₂ molecules into individual oxygen atoms that are intensely reactive. This atomic oxygen rapidly chews through most materials used in conventional satellite construction, corroding surfaces, degrading sensors, and weakening structural elements .
Aerodynamic torques are the third destabilizing force. The thin but uneven upper-atmospheric currents push and twist objects, constantly knocking them off their intended orientation. A satellite that can't correct these torques will quickly tumble out of control .
While government spy satellites and the International Space Station have operated in this range, no commercial operator has packaged a solution to all three problems into an economically viable satellite platform—until now .
NewOrbit's answer is a ground-up rethink of what a satellite should be for this specific environment. Rather than adapting a traditional spacecraft design, the company engineered its NEO-1 platform to turn VLEO's deadliest trait—the atmosphere itself—into an asset .
The heart of this innovation is the AURA thruster, a proprietary air-breathing electric propulsion system . Unlike conventional ion engines that must carry and deplete finite onboard propellant, AURA operates by scooping up atmospheric particles in real-time, ionizing them inside a radio-frequency gridded ion engine, and accelerating them to generate thrust
. In controlled lab tests, NewOrbit demonstrated continuous operation of an ion engine entirely on atmospheric air—an industry first—achieving a specific impulse of 6,380 seconds
.
This air-breathing capability solves the drag problem without burdening the spacecraft with heavy fuel tanks. It allows NEO-1 to perform sustained station-keeping and drag compensation for a planned operational life of up to five years at altitudes between 200 and 300 km .
Around this propulsion core, NewOrbit layered additional survivability measures:
The Series A funds are already being deployed into physical infrastructure. NewOrbit plans to open the NEO Production Complex, a dedicated satellite manufacturing facility in Reading's Thames Valley, in 2027 . The roughly 2,000-square-meter facility is being positioned as Europe's first purpose-built factory for VLEO satellite production
.
The company's roadmap is clearly defined: the complex will first complete integration of the inaugural NEO-1 demonstration satellite, with a target launch window in 2028 . Following that milestone, production will scale from approximately 10 satellites per year to an output of several per week, depending on customer demand
.
The commercial logic for enduring VLEO's harsh environment is straightforward: flying 15 to 30 times closer to Earth than conventional LEO constellations delivers step-change improvements in sensor resolution and communication signal strength .
Earth observation and high-resolution imagery is the most mature use case. Operating at roughly one-third the altitude of traditional imaging satellites allows optical payloads to capture what NewOrbit describes as "drone-quality imagery from orbit," at an estimated 20 times lower cost . Academic research supports this value proposition: studies from University College London have demonstrated that reducing orbital altitude substantially improves optical spatial resolution for a given payload size, or conversely allows equivalent performance with significant mass and volume savings
.
Direct-to-device 5G connectivity is a more ambitious market. From VLEO altitudes, NewOrbit claims its satellites can connect directly to standard, unmodified mobile phones without requiring terrestrial amplifiers or specialized antennas . This would remove the biggest cost and logistical barrier that has historically prevented direct satellite-to-phone service from scaling beyond low-bandwidth emergency texting.
Defence and intelligence applications represent the sector that originally proved VLEO's value. Sharper imagery, lower latency for signal interception, and the ability to pass over targets more frequently are all compelling advantages for government and security customers .
For all the technical ambition, NewOrbit faces a critical test: it has yet to fly in any orbit . The company's AURA thruster has demonstrated its air-breathing capability in laboratory vacuum chambers, and the European Space Agency awarded the company a €175,000 contract in 2024 to advance its air-breathing cathode technology
. However, proving the integrated platform can survive the combined assault of drag, atomic oxygen, and aerodynamic torques for years in the actual VLEO environment remains the milestone that will validate—or challenge—the company's thesis.
If NewOrbit's 2028 demonstration mission succeeds, it would not just open a new commercial orbital layer but could fundamentally reshape the economics of Earth observation and direct-to-device connectivity. The company's investors, from a seasoned space-focused venture fund to the architect of NVIDIA's GPU revolution, are betting that the company's purpose-built engineering can finally conquer an orbit that has remained untouched for 60 years.
