Area of Science:

  • Gravitational biology
  • Cellular biology
  • Protistology

Background:

  • Cellular gravitational research requires versatile instrumentation for studying organisms like protists.
  • Understanding cellular responses to gravity is crucial for space biology and astrobiology.

Purpose of the Study:

  • To describe the design and construction of CECILIA, a centrifuge for studying ciliate and flagellate behavior under varying gravity.
  • To enable quantitative evaluation of cellular responses to gravity in both ground-based and microgravity conditions.

Main Methods:

  • CECILIA features a horizontal rotating platform for up to six 8mm-camcorders and six experimental chambers.
  • The instrument allows for videomonitoring, videorecording, and quantitative data evaluation.
  • Chambers can be rotated under hypergravity (up to 15 g) to orient cells relative to the gravity vector.

Main Results:

  • CECILIA is designed for versatile cellular gravitational research, particularly for protists.
  • The system facilitates real-time monitoring and quantitative analysis of cell behavior.
  • It supports experiments under hypergravity, 1g, and microgravity conditions.

Conclusions:

  • CECILIA is a valuable tool for precursor investigations of ciliate and flagellate behavior under microgravity.
  • The instrument supports extrapolation of cellular responses from hypergravity to hypogravity conditions.
  • It is suitable for long-term experiments, including those planned for the International Space Station.
