Apply Now for 60-Day Bed Rest or 100-Day Isolation Study
Researchers at the German Aerospace Center (DLR) are seeking participants for two significant studies aimed at understanding the effects of isolation and microgravity on human health. The studies, SOLIS100 and SMC3, are set to begin in Spring 2026 at the DLR’s envihab facility in Cologne.
Application Period for Studies
Applications for participants are open until December 12, 2025. Both studies aim to explore the psychological and physiological challenges that astronauts may face during long-duration space missions. Interested individuals must meet specific criteria and undergo a rigorous selection process.
SOLIS100 Study Details
The SOLIS100 study will last for 100 days and simulate life in a confined space aboard a spacecraft. Six participants will live together under strict conditions, replicating an authentic space mission. They will perform various tasks, maintain their habitat, and experience the challenges of isolation and limited resources.
SMC3 Study Overview
The SMC3 (Sensorimotor Countermeasure Study) will focus on the effects of microgravity, utilizing bed rest as a model for simulating these conditions. Participants will experience 60 days in a bed positioned at a 6-degree incline, mimicking the fluid shifts that occur in space. This study is conducted in collaboration with NASA.
Participant Requirements
- Age: 24 to 55 years
- Height: Between 153 cm and 190 cm
- Body Mass Index (BMI): Between 18 and 28 kg/m²
- Good health and average fitness level
- Strong command of German (for SMC3 study)
Importance of the Research
These studies are critical as future space missions are expected to extend beyond Earth’s orbit, targeting the Moon and Mars. According to Dr. Amelie Therre from the DLR Institute for Aerospace Medicine, understanding the impacts of isolation and microgravity is essential for preparing astronauts psychologically and physically for long expeditions.
The SOLIS100 study follows the preliminary SOLIS8 study, which observed participants during an eight-day space mission simulation. By analyzing the results from SOLIS100 and SMC3, scientists aim to develop strategies for mitigating the effects of prolonged isolation and weightlessness.
How to Apply
Individuals interested in participating in either of the studies should submit their applications by December 12, 2025. The selection will include multiple rounds of testing and evaluations to determine medical and psychological readiness.
