Flagship Experiment
Pre-frozen mRNA-LNP tubes fly to the ISS, thaw on station, and run a BioBits cell-free reaction. Leaked messenger RNA unlocks a green fluorescent protein (GFP) switch, so how brightly a tube glows tells you how much cargo escaped.

Anatomy and failure mode
What sits inside an 80 nanometer LNP, how microgravity loosens the lipid membrane, and the tube chemistry that turns a leak into visible light.
Steps 01 to 06Rack layout
Standard PEG tubes, high PEG tubes, detergent controls, and calibration blanks assembled into a 16-tube rack with an identical Earth twin.
Steps 07 to 10Freeze and fly
Flash freeze, insulated cold-chain packing, launch vibration on a crew resupply flight, and transfer into the ISS science module.
Steps 11 to 14Storage and readout
Sustained microgravity storage, a simultaneous thaw on station and on Earth, and a handheld fluorescence read through a 585 nanometer filter.
Steps 15 to 18Encapsulation efficiency
The efficiency calculation, the flight versus ground comparison, the control tubes that validate it, and what each outcome would mean.
