Significance: Helps develop sustainable farming techniques for future space missions.

2. Cyanobacteria Growth in Space
Objective: Analyze how cyanobacteria (photosynthetic bacteria) behave in microgravity.
Process: Two strains will be compared for growth rates and biochemical changes.
Significance: Could lead to better life-support systems for spacecraft.

3. Sprouts & Microalgae Research
Objective: Examine germination and nutritional changes in space-grown seeds and algae.
Process: Post-mission analysis will assess genetic and microbial impacts.
Significance: Vital for developing space-compatible food sources.

4. Myogenesis (Muscle Loss Study)
Objective: Investigate muscle degeneration in microgravity.
Process: Identifying molecular pathways to prevent muscle atrophy.
Significance: Benefits astronauts and helps in medical research for muscle-related diseases.

5. Tardigrades (Microscopic Organisms)
Objective: Test survival and reproduction of tardigrades in space.
Process: Comparing space-flown tardigrades with Earth-based samples.
Significance: Helps understand life’s resilience in extreme environments.

6. Voyager Displays (Human-Computer Interaction)
Objective: Study how astronauts interact with screens in microgravity.
Process: Analyzing eye movements and stress responses.
