IDDK Co., Ltd. today announced that it has signed a Memorandum of Understanding (MoU) with Inbound Aerospace, a company developing an autonomous, unmanned, recoverable spacecraft operating in Low Earth Orbit (LEO) under microgravity conditions. The spacecraft is designed to re-enter the atmosphere, be refurbished, and relaunched, offering a reliable and reusable platform for space missions.
In April 2025, IDDK conducted its first demonstration mission to LEO in collaboration with another partner company, sending the Micro Bio Space LAB (MBS-LAB) – a palm-sized, fully automated platform for microgravity experiments – into space.
Building on this achievement, IDDK aims to further accelerate collaborations with partners worldwide to advance the commercialization of microgravity experiments.
Under the newly signed MoU, IDDK and Inbound Aerospace will explore opportunities for collaboration utilizing Inbound Aerospace’s spacecraft platforms, launch logistics, and re-entry capabilities. The partnership will include the development and operation of dedicated spacecraft designed to accommodate IDDK’s MBS-LAB, as well as the establishment of ground support infrastructure and mission control services.
This joint initiative represents a major step toward democratizing access to space-based experiments. By leveraging unmanned spacecraft rather than the manned International Space Station (ISS), the collaboration will enable companies and institutions—even from countries not participating in the ISS program—to access microgravity environments on demand, effectively providing “microgravity as a service.”
Moreover, the use of unmanned and reusable platforms will make space experiments more affordable, efficient, and flexible, expanding the range of possible research and industrial applications.
About IDDK
IDDK was established in June 2017 by Soichiro Ueno, the founder and CEO, and has been developing business using the patented cutting-edge technology, Micro Imaging Device (MID).
IDDK is working on the space bio experiment field as a social implementation of MID. IDDK democratizes space experiments. We do this with MID applying to artificial satellites, constructing the Micro Bio Space LAB (MBS-LAB) inside the satellites.
About Inbound Aerospace
Inbound Aerospace was established in 2025 by Dr Aravind I B, Vishal Reddy and Capt Abhijit Bhutey with the vision of developing a Low Earth Orbit-based autonomous, unmanned, free-flying, recoverable spacecraft for customers who want to conduct in-orbit technology demonstrations, microgravity research, or in-space manufacturing of products that have use cases back on Earth.
Once the spacecraft is injected into the Low Earth Orbit, it facilitates the operation on the customer’s payload. On completion of the orbital experiments the spacecraft de-orbits and lands autonomously on a runway to return the finished products to customers. This allows for post-flight inspection, analysis and further development strategies. The spacecraft has multiple use cases especially in the life science and material science domains for producing low volume high value products.
