The Nova Variable: Why Stoke Space's Upper Stage is the Real Story

In the current launch landscape, the industry is staring down a capacity crisis. As Ars Technica first reported, satellite operators are increasingly concerned about a looming undersupply of launch options in the U.S. as SpaceX moves toward phasing out the Falcon 9 in favor of the Starship. This vacuum is already driving companies like Reflect Orbital—a startup planning a 50,000-mirror constellation—to look toward India's Skyroot Aerospace for launch capacity via the Vikram-1 and Vikram-1U rockets.

But for those tracking the long-term math of low-Earth orbit (LEO), the most critical development isn't the search for immediate capacity—it's the pursuit of full reusability. This is where Stoke Space becomes the central narrative.

According to reporting from Ars Technica, Stoke Space has shipped the reusable upper stage of its Nova rocket from its Kent, Washington, factory to a test facility in Moses Lake, Washington. This stage is slated for a hotfire campaign utilizing its Andromeda engine and cryo-proof testing. While Nova's first stage is a more conventional reusable booster, the upper stage is the disruptive element. Stoke has engineered the Nova for full reusability, incorporating a regeneratively cooled heat shield and an Andromeda engine powered by a ring of 24 thrusters.

***Opinion:*** *If Nova's reusable upper stage actually delivers, the cost-per-kilogram math for LEO changes overnight. Most current reusable systems only recover the first stage; by recovering the second, Stoke could fundamentally shift the economic ceiling of orbital delivery.*

This milestone arrives as other players in the medium-to-heavy lift sector hit turbulence. Ars Technica reports that Rocket Lab has pushed the debut of its Neutron vehicle to 2027. The delay stems from manufacturing hurdles with the rocket's carbon-composite structures—specifically, the discovery of air pockets, or voids, within the carbon-fiber layers of the first-stage propellant tank's forward dome.

Meanwhile, the smallsat market is seeing new entrants. Space News reports that Colorado-based LEAP is targeting a 2028 entry with its Bighorn rocket, which is designed for a 320-pound (145-kilogram) payload capacity to LEO. LEAP CEO Chris Beckman has emphasized a strategy of mass production, with a Denver-area factory capable of scaling to two vehicles per month. While LEAP has already flown a suborbital Bullfrog rocket, the Bighorn represents a different scale of ambition.

Ultimately, the industry is in a state of transition. Between the delays at Rocket Lab and the production ramp-ups at LEAP, the gap in reliable, cost-effective launch capacity is widening. If Stoke Space can successfully navigate the tests at Moses Lake and hit its goal of launching Nova next year, it won't just be adding another rocket to the calendar—it will be challenging the very cost structure of the orbital economy.
