E U R E K A - 1



As demonstrated by SpaceX, Blue Origin, Virign Galactic, and others, the key to radically affordable spaceflight lies in mitigating the enormous cost of space-capable vehicles. That's why Eureka-1 is designed to be fully reusable and return from space intact via parachute.

Additionally, Eureka is fully modular- in the event of damage to any parts on landing, they can be quickly and cost-effectively replaced. In fact, almost all of Eureka can be assembled with tools you probably have in your garage.  



In contrast to other rockets that use toxic, corrosive fuels, Eureka-1 is powered by Nitrous Oxide and Ethanol- two of the safest, least harmful propellants available.  In addition to their non-toxicity, both nitrous oxide and ethanol are 100% renewable. 

In an effort to further reduce the environmental impact of Eureka-1 and mitigate the release of harmful "NOx" compounds, our ASCELLA engine is designed to decompose 99.98% of onboard Nitrous Oxide into harmless Nitrogen and Oxygen gas.



Our Ascella ( Latin for "wing") engine is a powerhouse, delivering 10 kN (2,250 lbs) of force at launch, increasing to 12 kN (2,700 lbs) towards the end of the 75 second burn, Ascella is the white-hot glowing heart of Eureka-1.

Ascella is also one of the most cost-effective engines ever built. By forgoing expensive and complex turbopump systems and manufacturing the engine through EBAM (Electron Beam Additive Manufacturing), material waste is minimized while retaining strength and performance.



Eureka-1 is capable of reaching a maximum altitude of 200 km (575,000 ft) unladen, dropping to 135 km (442,000 ft) with the addition of a 10 kg (22 lbs) payload and associated recovery equipment.

This will surpass both the current college altitude record of 44 km (144,000 ft) and the world amateur record of 116 km (381,000 ft).



With 15 kg of mass capacity and 40 liters of usable volume, Eureka-1 offers unprecedented access to space for small payloads- a niche traditionally relegated to sub-optimal ride sharing on larger vehicles with inflexible flight plans. 

In more concrete terms, Eureka can carry up to 18 individual experiments packed into the 1-U Cubesat form factor.



Eureka-1's carbon fiber/aluminum airframe saves weight while retaining structural strength in  near-hypersonic flight (up to Mach 4.8).

The "boat-tail" structure on the aft end of Eureka significantly reduces drag, enabling the rocket to slip through the transonic regime with minimal aerodynamic loading.

On the way down, Eureka uses a two-phase parachute deployment system than enables it to smoothly decelerate, landing at a brisk walking pace.



Eureka-1 is designed to be one of the safest and most reliable vehicles ever constructed. By using proven designs and technology and operating with healthy safety margins, Eureka-1 minimizes risk without compromising on mission capability.

For example, the boat tail around the engine doubles as a shield in the event of an engine failure. By allowing hot gases to escape while guarding against shrapnel, the engine skirt protects bystanders in the key moments when flying debris poses the most risk.


To boldly go where few have gone before:

Access to space is tremendously expensive. If you're not a giant company, your best shot at the final frontier is a ride sharing contract where your payload and mission have to conform to the requirements of the premier customer. 

Through innovative design, cost-saving measures, and a commitment to opening up access to space, SEB has reduced the per-launch cost of a suborbital sounding rocket from $2.8 million to less than $200,000- a cost reduction of almost 140x.

Eureka-1 is not intended to compete directly with  NASA's Terrier-Orion or Black Brand. Those vehicles have impressive capabilities, a proven flight record, and can carry heavier payloads far higher than Eureka-1 could ever reach. Instead, Eureka-1 fills a key niche that's so far been tremendously neglected: launching small payloads from small customers to an altitude previously thought unattainable at this price point.

EUREKA-1 goes global with PROJECT KARMAN:

Space Enterprise at Berkeley officially challenges colleges across
the nation to join us in the Intercollegiate Space Race of the 21st Century, competing to see who
can truly be the first to launch its own rocket past the Karman Line.


(1) All organizations intending to compete must publicly declare their
participation online and in applicable media outlets.

(2) Organizations must be student-led, and the final rocket must design all major
components in-house (no recycled LR-101s!)

(3) Design and production of each team's rocket must be a transparent process.

This entails regular updates, published design drawings and technical papers, and a timeline made
available to the public. Ultimately, we're counting on you to act in good faith. Just because it's
a space race doesn't mean it should be a cold war!
