Germany has developed robust suborbital launch capabilities through its national aerospace agency, DLR (Deutsches Zentrum für Luft- und Raumfahrt), primarily via the MAPHEUS and TEXUS programmes.

MAPHEUS

Initiation: 2009

Purpose: Conducts microgravity experiments in materials science, life sciences, and technology testing.

Launch Frequency: Typically one mission per year.

Altitude: Reaches up to 260 km, providing over 6 minutes of microgravity.

Recent Missions: MAPHEUS-14 launched in January 2024; MAPHEUS-15 launched in October 2024.

TEXUS

Initiation: 1976

Purpose: Facilitates scientific physical tests and technology trials in microgravity, often as precursors to ISS experiments.

Altitude: Achieves up to 250 km, offering approximately 6 minutes of microgravity.

Recent Missions: TEXUS-60 launched in March 2024.

Prerequisites:

• Institutional & political interest and support for access to space

• Technical and engineering capabilities for manufacturing launchers

• Ground infrastructure (engine test stands, labs, propellant facilities, AIT facilities, clean rooms, etc.)

• Suitable space for launches, ideally a coastal or desert location with clear range over uninhabited areas and testing and range facilities (or agreements to use partner facilities)

• Clear regulatory framework for launch licensing, safety, and liability

• Export-control compliance, insurance, and mission assurance processes

• Partnerships with experienced launch providers 

Cost:

Lite programmes such as university/tech demos, hosted suborbital launches

• Ballpark: USD 5M–50M

• Includes: technology development for reusable suborbital vehicles or hosting international suborbital providers, payload integration facilities, safety and licensing frameworks, training for engineers and operators, test flights for microgravity or atmospheric research

Full suborbital programme

• Ballpark: USD 50M–300M + USD 5M–15M/yr (OPEX)

• Includes: design and manufacturing of reusable suborbital vehicles, development of propulsion and guidance systems, construction of launch and landing facilities, integration and test infrastructure, range safety and airspace coordination systems, workforce development, operations and maintenance.

Timeframe:

Lite programme:

• Overall 24–48 mo

• Phase: partnership agreements & design studies (6–12 mo), infrastructure adaptation or facility development (12–18 mo), test flights & payload integration (12–18 mo)

Full programme:

• Overall 60–120 mo

• Phase: feasibility and vehicle design (12–24 mo), infrastructure build (18–36 mo), prototype development and test flights (24–36 mo), operational suborbital launch service (12–24 mo)

Pros:

• Scientific Research - Provides a cost-effective platform for microgravity experiments, benefiting materials science, biology, and technology development.

• Technology Validation - Enables testing of satellite components and systems in space-like conditions before committing to orbital missions.

• Educational Opportunities - Offers hands-on experience for students and researchers, fostering STEM education and workforce development.

• International Collaboration - Partnerships with organizations that enhance research opportunities and resource sharing.

Considerations:

• Limited Microgravity Duration - Suborbital flights offer only a few minutes of microgravity, which may not suffice for certain experiments.

• Launch Constraints - Dependence on specific launch sites can introduce scheduling and logistical challenges.

Funding and Sustainability - Securing consistent funding for long-term research programs remains a continual challenge.
