Video unveiled of Astron's 100% reusable small rocket

UK rocket company Astron Systems has released a video showcasing their 100% reusable rocket “Aurora” for small payloads. With Aurora, Astron Systems are aiming to lead the way globally in bringing 100% rocket reusability to small lift launch, with the goal of unlocking a step change improvement in the cost, speed, and flexibility of services for small payload orbital launch and return. The Aurora rocket is a two stage vertically launched vehicle designed for the orbital launch and return of small payloads.

Race 2 Space students hosted on Astron's test site

We helped out with hosting students for the UK's Race 2 Space 2025 competition at C-Site, our propulsion test facility. Race 2 Space is a national competition founded to boost practical skills and diversity among graduates entering the UK space sector. Over a two-week period, more than 300 students from 32 universities will have travelled to the Westcott Space Cluster and fired their rocket engines.

Spiral Blue sign launch agreements with Astron Systems

We're excited to share that we've signed a first batch of 3 launches with Australian company Spiral Blue to help deploy their lidar technology into space. We love what they're building and what they've achieved already with their space edge computing technology currently in orbit and look forward to this first batch of launches with them from 2029.

Astron graduates from prestigious Techstars Space accelerator

That's a wrap on the Techstars Space Accelerator 2024! It's been an amazing 3 month program, culminating in the demo day at Google LA last Thursday! Momentum is definitely building, and we're excited for the months ahead and continuing to lead the way in bringing real commercially competitve launch for small payloads to Europe and beyond!

Prototype torch igniter performs well with gaseous testing

We're excited to share some footage of gaseous testing of our first reusable rocket engine torch igniter prototype. This is a part of our highly reusable rocket engine in development, which in turn is a key technology within our fully reusable Aurora launch vehicle. The data from this testing is valuable for validating simulations and demonstrating survivability. We've run this igniter for multiple full flight duration burns, and it has been ignited cumulatively for over 2 hours demonstrating long expected lifetime.

Prototype new hybrid electric turbopump tested pumping cryogenic propellant

Whilst combustion chamber and thrust chamber tests often catch people's eye, they are far from the most complex parts of rocket engines. The heart of an orbital rocket engine, and by far the most complex piece, is the pump system. We're excited to share this footage of testing with cryogenic liquid nitrogen this first prototype concept hardware fuel-side hybrid electric turbopump. This is a huge technical milestone towards development of our highly reusable rocket engine in development, which in turn is a key technology within our fully reusable Aurora launch vehicle.
