The International Space Station (ISS) gives scientists the opportunity to study the effects of space travel on human and plant tissues as well as understand how physical materials react during formation or exposure to a microgravity environment. CSS provides integrative expertise to NASA to support research and development and technology demonstrations conducted on the ISS, including a recent experiment testing a new technique for growing semimetal conductor composite crystals in microgravity. The intent is to develop these crystals into “wafers” by capitalizing on the unique physical characteristics of microgravity that reduces the potential for inconsistencies and imperfections during the formation process improving their use in electronic devices.  

CSS employee owners provide ground support to missions to the International Space Station.

For this effort, CSS employee owners work with all the stake holders (NASA project team, principal investigator (PI) team, operations team and ISS Integration team) to develop a research mission that ensures all science objectives and engineering requirements are met, and the payload is safe for ISS operations. Additionally, CSS staff support ISS crew members during real-time operations to ensure mission success. Finally, after the testing, CSS ensures delivery of the samples/ science back to the PI team for analysis.

The new material recently endured a successful mission on orbit, and the team turned over six new samples for delivery to the International Space Station.

Developing a Stream Assessment Protocol 

CSS has been a significant contributor to the development and implementation of the Oregon Stream Function Assessment Method (SFAM) for more than 10 years. SFAM is a key component of the Oregon Stream Mitigation Program administered by the Oregon Department of State Lands.  The mitigation program is designed to address damage to aquatic resources caused…

Preparing and Delivering Samples for Travel to the International Space Station

CSS employee owners on contract with NASA delivered six newly prepared Solidification Using a Baffle in Sealed Ampoules (SUBSA)—a high temperature furnace with temperature and timing control for melting samples to create different materials and alloys—samples for the NG-23 launch, which took place on September 14, 2025. On this mission, samples are being delivered for…

An Approach to Assessing Laboratory Space 

CSS employee owners were part of a team of scientists at the National Institutes of Health who developed an approach to evaluating new laboratory space to determine if the space will fit operational needs. This concept, titled The BaseLINE Approach, combines traditional safety processes with additional safety and environmental factors to assess before operations begin.…
