Gain flight heritage with frequent reentry

Varda’s hypersonic flight test bed is the off-the-shelf method to reproduce the most challenging hypersonic and reentry flight environments without building a costly dedicated representative test vehicle. You gain flight heritage through Mach 25 and advance your TRL.


Affordable, frequent, and recoverable high-hypersonic flight testing

Varda’s orbital capsule enters the atmosphere at 18,000 miles per hour. The capsule hits Mach 25+ on every mission before landing by parachute on Earth. This offers a real flight environment for hypersonic reentry vehicle subsystems such as thermal protective materials, navigation, communication, and sensors. Test as you fly, fly as you test.

Mach 25+ Flight

It is impossible to replicate the coupled aero-thermal-chemistry conditions at high-hypersonic flights on the ground.

High Heat Flux

Varda’s capsule experiences sustained plasma conditions in flight: 300W/cm² heat flux. 18,000K+ in the flow field.


Our commercial customers require low cost reentry, leading to cost benefits for government missions.


High-fidelity data and simplified post-flight analysis on payload.


By 2026, Varda expects a monthly reentry cadence between government and commercial demand.


Our commercial business relies on successful recovery of the capsule, every mission, every time.

Configurable Payload

Varda’s payload capacity allows over 100W of power, tens of kilograms of internal mass, and plenty of area for TPS.

Increase TRL

Gain flight heritage where it matters most. Build confidence in transitioning capability.

Frequent reentry, from orbit to Earth

Varda’s capsule is designed for rapid iteration and high production rates. We dream of reentry becoming as commonplace as launch and space just another location to manufacture. Modular in design and ready-built for materials rather than humans—our capsule completes the space logistics chain.

Why now?

The missing link in agile aerospace

The hypersonic test regime currently lacks real-world testing environments and the rapid cadence required to derisk our most advanced aerospace vehicles. Ground testing overly simplifies the coupled flight environment at high Mach speeds, and representative test vehicles are infrequent and expensive. Varda’s capsule offers true-to-flight conditions offering a path to quickly gain flight heritage when it matters most.
