Cephalad fluid shifts in microgravity increase intracranial pressure, leading to structural eye deformation and vision impairment. Non-invasive, flight-ready therapies or fluid-redistribution suits are urgently required.

3D-printing complex structural metal components in microgravity often results in porosity and micro-cracks. We need reliable thermal controls and melt-pool monitoring for zero-g metal and composite fabrication.

Plants grown in space suffer from water-logging and oxygen starvation around roots due to absence of buoyancy-driven convection. Developing autonomous micro-fluidic aeration root systems is essential for growing fresh crops in space.

Robotic planetary landers are restricted by payload weight and power, making complex lab chemistry difficult on site. Micro-fluidic lab-on-a-chip biosensors are required to analyze Martian or icy moon soil in-situ.

Missions passing from the inner solar system to the deep outer cold face severe thermal swings that degrade instruments. Variable emissivity smart materials and active thermal fluid loops are needed.

ZBLAN optical fibers produced in space exhibit far lower light attenuation than Earth-made fibers, but manufacturing defect rates remain high. Microgravity fluid dynamics and draw-tower controls must be perfected.

Primary mirrors for space telescopes cannot exceed launch vehicle dimensions without complex, failure-prone mechanical folding. Dynamic fluidic mirrors and membrane optics created in orbit offer a promising alternative.

Without gravity, liquid fuels float randomly inside tanks, causing air bubbles to enter fuel pumps during orbital refilling. Scalable fluid-settling systems and bladderless zero-g fuel transfer ports must be built.

Turbulent flow, like water rushing through a pipe or air moving over a wing, is notoriously hard to describe with exact mathematics. A complete theory would improve everything from weather prediction to aircraft design.
