Purpose of the Study:
- To document the process of a first-time Principal Investigator in Space Life Sciences.
- To investigate the long-term impact of microgravity on the circadian rhythm of Trigonoscelis gigas.
- To detail the development and execution of a spaceflight experiment within the Mir Program.
Main Methods:
- Proposal development and submission for a novel space life sciences investigation.
- Design, fabrication, and rigorous testing of specialized spaceflight hardware.
- Execution of the Mir Beetle experiment aboard the Mir space station, including data collection.
Main Results:
- The paper outlines the procedural steps and challenges encountered during the experiment's lifecycle.
- Observations regarding the beetle's adaptation and biological clock function under microgravity conditions are discussed.
- The collaborative efforts between US and Russian scientists are highlighted.
Conclusions:
- Successfully managing a space life sciences investigation from conception to completion is achievable for new Principal Investigators.
