Arthropod model systems for studying complex biological processes in the space environment.

Area of Science:

• Space Biology
• Arthropod Physiology
• Exobiology

Background:

• Space biology research utilizes model organisms to understand life's response to extraterrestrial conditions.
• Arthropods like Drosophila melanogaster and Artemia offer valuable systems for studying development and aging under altered gravity and radiation.

Purpose of the Study:

• To evaluate the complementary roles of Drosophila melanogaster and Artemia in space biology research.
• To investigate the effects of microgravity and space radiation on arthropod development, aging, and motility.
• To identify cellular mechanisms underlying arthropod responses to the space environment.

Main Methods:

• Utilizing biosatellite flights with automated devices for Drosophila melanogaster reproduction and motility recording under varying g-levels and microgravity.
• Conducting experiments on the International Microgravity Laboratory-2 to grow Drosophila embryos and record adult male motility.
• Exposing Artemia dormant gastrulae to space conditions (atmosphere/void) using the ESA Biopan facility for post-flight developmental and aging analysis.

Main Results:

• The study outlines planned experiments rather than presenting completed results.
• Methodologies are established to assess developmental and aging responses in arthropods post-space exposure.
• Future experiments will build upon these foundational studies to explore cellular mechanisms.

Conclusions:

• Space biology can benefit from the combined use of Drosophila melanogaster and Artemia models.
• Further research is needed to elucidate the specific cellular mechanisms affected by spaceflight in arthropods.
• Understanding these effects is crucial for future long-duration space missions and astrobiology.
