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 up-front 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-1 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-1 can be assembled with tools you probably have in your garage.  



In contrast to other rockets that use toxic, corrosive propellants, EUREKA-1 is powered by liquefied oxygen and residential-grade propane. While non-renewable, propane fuel paves the way for future developments in condensed biogas propulsion, opening up the way for highly efficient, 100% renewable propellants.

In addition, Eureka is designed to minimize or eliminate the use of rare-earth metals, petrochemical-derived materials, and Proposition 65 hazardous substances.    


Traditional rocket engines are made from so-called Refractory Alloys, metals like Inconel, Tungsten, Rhenium, Titanium, and others. While these offer impressive performance capabilities, they are heavy, difficult to work with, and environmentally disastrous.

In April of 2018, SEB will test and publicly unveil our ASCELLA engine- the largest composite engine ever fired by a college team, and the first liquid engine to ever use CFOAM-30, a ground breaking carbonaceous foam that combines low density with outstanding thermal resistance and chemical stability.

CFOAM's exceptional properties have allowed SEB to replace over 90% of the metal typically used in liquid rocket engines with low-density composites, reducing weight by over 70% compared to traditional engines.     



EUREKA-1 is designed to reach a maximum altitude of 135 km (443,000 ft), placing it firmly above the Karman Line (the formal border of space) and setting the stage for a new generation of high-altitude research endeavors including bio prospecting, climate science, and real-world engineering systems validation.

If successful, Eureka 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-1can carry up to 18 individual experiments packed into the 1-U Cubesat form factor.



By using a unique combination of fiberglass, carbon fiber, meta-aramid fibers, and aluminum, Eureka's  airframe balances outstanding structural strength and light weight, all without a single weld or hot-working process.

On the way down, EUREKA-1 uses a single-phase parachute deployment system in conjunction with a cold-gas propulsive landing assist system to ensure a soft and controlled touchdown less than 5 miles from the launch site.



EUREKA-1 is designed to be one of the safest launch vehicles ever made. By operating our engine and tanks at ultra-low pressure (by rocket standards) and exceeding NASA recommended safety standards across the board, Eureka offers safety comparable to a hybrid rocket while incorporating the 70 year proven history of liquid bipropellants.


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 initial cost of a suborbital sounding rocket from $2.8 million to less than $100,000- a cost reduction of almost 280x. With successful recovery and flight turnaround, the per-launch cost of Eureka could drop to as low as $5000 per flight, with the only recurring costs being propellant and periodic re-conditioning of the engine.

EUREKA-1 is not intended to compete directly with  NASA's Terrier-Orion or Black Brant. 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.
