The Mission
ISAR Aerospace was founded with a clear goal:
To provide affordable, flexible, and sustainable launch services for small and medium-sized satellites.
As the global demand for commercial satellite deployment rises, especially from companies offering internet services, Earth observation, defense, and weather monitoring, ISAR aims to be Europe’s answer to SpaceX for small payload launches.
The Spectrum Launch Vehicle
Key Details:
- Type: Two-stage orbital launch vehicle
- Height: ~28 meters
- Payload Capacity:
- LEO (Low Earth Orbit): up to 1,000 kg
- SSO (Sun-Synchronous Orbit): ~700–850 kg
- LEO (Low Earth Orbit): up to 1,000 kg
- Propulsion: In-house developed Aquila engines, using RP-1 (kerosene) and liquid oxygen (LOX)
- Status: Final stages of development with a first launch expected in 2025
Sustainability Focus:
- Designed to minimize carbon footprint and offer cost-efficient satellite access to space with eco-conscious propellants and lean manufacturing.
Technology and Innovation
- In-house Engine Development:
Their proprietary Aquila engine is a highlight of German engineering fully 3D printed and tested for cost-efficiency and durability. - Advanced Manufacturing:
ISAR uses additive manufacturing (3D printing) for parts, streamlining the design-to-launch cycle, and reducing weight and production time. - Vertical Integration:
Unlike many companies, ISAR builds nearly everything from engines to software—in-house, giving it tighter control over cost, quality, and innovation. - Autonomous Guidance Systems:
ISAR’s Spectrum will feature advanced navigation and control systems for precise payload deployment.
Funding and Growth
ISAR has raised over $180 million USD through multiple funding rounds, making it one of Europe’s best-funded space tech startups.
Key milestones:
- 2021: Raised €75 million Series B
- 2023: Announced new strategic investments and expansion
This strong financial backing has allowed ISAR to build its own test stands, production facilities, and even a dedicated launch site.
Launch Infrastructure
Launch Site:
- Andøya Spaceport, Norway
- Will be Europe’s first private orbital spaceport
- ISAR holds exclusive rights to launch from there, ensuring operational independence
Integration Facility:
- Inaugurated in 2023, the headquarters in Ottobrunn includes:
- Rocket integration bays
- Testing labs
- Mission control rooms
- Rocket integration bays
Partnerships and Recognition
- Selected by the European Space Agency (ESA) under its Boost! initiative
- Working with European governments and private firms to launch constellations of satellites
- Partnered with Amazon Web Services (AWS) for mission operations and data services
- Collaborating with space agencies, universities, and defense firms to offer turnkey orbital access
