STACO: Liquid Column Stability Under Microgravity on Spacelab-D2

Spacelab-D2 mission data from 1993 on the mechanical stability of liquid columns in microgravity. The experiment subjected a 30 mm diameter, 85 mm long silicone-oil column to controlled stimuli like disc rotation, oscillation, and volume change. Results include video sequences of column behavior and telemetry data on stimuli and parameters.

Use Cases

• Modeling liquid bridge stability limits based on recorded mechanical disturbances like disc oscillation and separation.
• Analyzing fluid shape deformation caused by microgravity 'g-jitter' based on the background sensing video data.
• Validating theoretical predictions of column response to forced axial vibration based on the high-accuracy image analysis results.
• Comparing stability behavior with other space experiments (TEXUS, SL-D1) based on the described geometry and Bond number.

Strengths

• Includes high-accuracy image analysis with precision reported as approximately 30 microns in object size.
• Describes specific experimental parameters: a 30 mm diameter, 85 mm long column using silicone-oil 5-10 times more viscous than water.
• Allows direct comparison with prior experiments due to standardized support disc geometry (30 mm diameter).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
