Low-gravity Orbiting Research Laboratory Environment Potential Impact on Space Biology Research

摘要: One of the major objectives any orbital space research platform is to provide a quiescent low gravity, preferably zero gravity environment, perform fundamental as well applied research. However, small disturbances exist onboard earth platform. The impact these must be taken into account by scientists during their planning, design and data analysis in order avoid confounding factors science results. reduced environment an orbiting orbit complex phenomenon. Many factors, among others, such experiment operations, equipment operation, life support systems crew activity (if it crewed platform), aerodynamic drag, gradient, rotational effects vehicle structural resonance frequencies (structural modes) contribute form overall which performed. contribution or accelerations precisely why NOT but acceleration environment. This paper does not discuss other radiation, electromagnetic interference, thermal pressure gradient changes, acoustic CO2 build-up name few that affect well, focuses solely on magnitude level found laboratory used conduct For ease this divides frequency spectrum relevant most disciplines three regimes: a) quasi-steady, b) vibratory c) transient. International Space Station example illustrate point. discusses regimes biology results from flown experiments are potential negative (accelerations)
