Center of Applied Space Technology and Microgravity (ZARM) of Germany offers two key platforms for microgravity research. The ZARM Drop Tower provides up to 9.3 seconds of high-quality microgravity by dropping experiment capsules from a 146-meter shaft. In parallel, the GraviTower Bremen Pro, a next-generation system, enables high-frequency microgravity experiments of up to 2.5 seconds each and supports partial gravity environments (e.g., Moon, Mars). Together, these facilities support a wide range of scientific and industrial research applications.

Prerequisites

• Access to technical expertise in microgravity experiment design

• International partnerships with agencies or commercial providers

• Procurement pathway

• Partner support as needed

Cost:

• Ballpark: USD 10k–20k (clinostats / desktop simulators), USD 50k–200k (drop tower experiments, e.g., ZARM Bremen), USD 100k–500k (zero-g parabolic flights, USD 0.5M–2M (suborbital flights), USD 1M–10M (ISS access via space agency/ ISS National Lab)

• Includes: experiment design and preparation, integration and safety reviews, hardware procurement or adaptation, launch or facility access fees, data collection and analysis, researcher training and travel

Timeframe:

• Overall: 6–36 mo (depending on platform)

• Phase: experiment design & review (3–6 mo), integration & preparation (3–12 mo), execution of experiment (days to weeks for drop tower/flight; months for ISS), data analysis & reporting (3–12 mo)

Pros:

• Innovation Enablement – Expands research opportunities through increased use of microgravity platforms, fostering scientific and technological innovation.

• Cost Sharing – Reduces the financial burden of space research through collaboration with commercial initiatives and shared investment models.

Considerations:

• IP and Data Governance Complexity – Involves negotiating intellectual property rights, data access, and ownership agreements, which can be legally intricate and time-consuming across different platforms and partners.
