Laboratories and Projects

Bone and Signaling Lab at Ames

Bone and Signaling Lab

The Bone and Signaling Laboratory is a multi-investigator collaborative facility that investigates the physiological responses of bone to the spaceflight environment. The current laboratory principal investigators focus their work on diverse research goals and synergize to share ideas, equipment and resources. 

Biospecimens in NBISC


The Space Biology Biospecimen Sharing Program (BSP) collects biospecimens to maximize the scientific return from biological studies and to encourage and broaden participation in space biology research. The NASA Biological Institutional Scientific Collection (NBISC) is a biorepository of non-human samples collected from NASA-funded studies.


NASA Open Science Data Repositories expands scientists' access to space-related experiments that explore the biological response of terrestrial biology to spaceflight environments. Our mission is to maximize the utilization of the valuable biological research resources and enable new discoveries.

Countermeasures Lab

The Laboratory of Countermeasures Development is addressing key challenges associated with use of medications in spaceflight missions. We also provide assessment of long-term spaceflight on drug metabolism due to changes in the human body that are caused by exposure to space.
