mikelepage: Carousel Spacelab (free-flying variable-g centrifuge)

Design summary

  • Market logic. Variable g leverages the existing micro-g in-space production market. Micro-g is needed only during the experiment, and setup and harvest are easier with buoyancy and sedimentation. So the product is a small, station-serviceable free-flying centrifuge with astronaut-replaceable payloads mikelepage, 2022-08-26.
  • Hardware. Space origami, ~1 m stowed and 3 m deployed, carrying 12 cubesat-form payloads. Launch on Electron or F9 rideshare; payloads swapped J-SSOD-style with a robotic arm; a "master control knob for gravity" mikelepage, 2022-08-30.
  • Business case. From the ISS R&D conference 2022: liver organoids (2-month process, ~6 weeks of culture; 10% of the liver waitlist die) could pay for 4 CLDs, in 2-month batches mikelepage, 2022-09-08.

Critiques raised

Open questions

  • Do organoid and biomanufacturing customers pay for adjustable g rather than just micro-g?
