BREMEN, Germany — German launch services provider Exolaunch is poised to revolutionize the space launch sector with the introduction of its new Exotube adapter, intended for use in six constellation launches commencing in 2026.
The Exotube, showcased at the Space Tech Expo Europe in Bremen, represents a universal modular adapter designed to facilitate the integration, launch, and deployment of spacecraft ranging from small cubesats to larger satellite systems weighing up to 500 kilograms. This innovation is set to enhance the flexibility and efficiency of satellite launches.

The Launch Strategy
The inaugural implementation of the Exotube will take place on either an American medium or heavy-lift launch vehicle in the first quarter of 2026. Exolaunch has already secured contracts for six launches with a constellation customer, demonstrating the adapter’s anticipated demand in the space industry.
Notably, the Exotube features a hexagonal base coupled with a cubic upper structure. This design includes integrated cameras that facilitate the capture of images and videos during satellite separation. According to Connor Pollock, mission director at Exolaunch, “The Exotube is the next big step for us. It’s scaling up and preparing eventually to be booking launches as a primary customer. It’s a big enabler for us.”
Structured Innovation
Exolaunch has identified a gap in the market and the growing demand for satellite launches. Pollock highlights their success with the SpaceX transporter program but notes that it has not sufficiently met the launch supply needs for the increasing number of small satellites. He pointed out that “all of the missions for the next two years on Transporter are fully booked,” signaling a need for more versatile launch options.
Exolaunch Exotube Summary
Characteristics of the Exotube Adapter
| Feature | Description |
|---|---|
| Design | Hexagonal base with cubic upper structure for versatile integration. |
| Camera Integration | Equipped with cameras for real-time image and video capture during satellite separation. |
| Launch Compatibility | Agile design that allows usage across small, medium, and heavy-lift vehicles. |
| Material | Initially constructed from aluminum for flexibility, with future developments in carbon fiber. |
| Launch Flexibility | Facilitating secondary rideshare solutions to maximize payload efficiency. |
Material Choices and Efficiency
The Exotube is primarily composed of aluminum, chosen for its balance between versatility and cost-effectiveness. Pollock explained, “Aluminum is great because you can move fast. You can change the design quickly with new interfaces if you have new customers.” However, he acknowledged the weight disadvantage of aluminum compared to carbon fiber, which provides greater weight efficiency but comes with higher costs and longer lead times in production.
“We are currently developing a carbon fiber hex structure for constellations,” Pollock added, demonstrating Exolaunch’s commitment to innovation and efficiency. He emphasized that all configurations for satellite deployments are generally constrained by volume, making mass less impactful in many scenarios.
Company Background
Founded in 2011, Exolaunch has established itself in the space industry with over 400 satellite deployments across 30 missions. The company has effective collaborations with clients from over 40 countries, showcasing its global reach and expertise in satellite deployment solutions.
Future Implications
The integration of the Exotube is expected to not only enhance Exolaunch’s launch capabilities but also set new standards within the industry for flexibility and efficiency in satellite deployments. As the demand for satellite launches continues to surge, innovations like Exotube will play a crucial role in meeting and exceeding these growing service requirements.
In conclusion, Exolaunch’s Exotube adapter marks a significant advancement in the efficiency of satellite launches and deployment strategies, emphasizing the importance of modular design and adaptability in an increasingly competitive space market.
