Spaceflight opportunities on the ISS for plant research--the ESA perspective.
Two ESA facilities will be available for plant research and other biological experiments on the International Space Station: the Modular Cultivation System (MCS) and BIOLAB. While BIOLAB will be launched with the European "Columbus" Module, MCS will be part of the Early Utilisation Agreement with NASA and integrated in the US Lab. Both facilities use standard Experiment Containers, mounted on two centrifuge rotors providing either microgravity or variable g-levels up to 2xg. Transparent covers allow illumination and observation (also near-infrared) of the internal experiment hardware containing the plant specimen. Standard interface plates provide each container with power and data lines, gas supply (controlled CO2, O2 and water vapour concentration; ethylene removal), and--for MCS only--connectors to water reservoirs. Besides the two concepts of environmental control in both facilities, there is a difference in container size (BIOLAB 0.36 l, height with respect to the g-vector 60 mm; MCS 0.58 l, height 160 mm) and in the degree of automation. The design of BIOLAB and MCS will be complimentary to NASA's Plant Research Unit (volume 20 l, height 380 mm) and should allow continuation of Space research on protoplasts, callus cultures, algae, fungi and seedlings, as earlier flown on Biorack, and new experiments with larger specimens of fungi, mosses and vascular plants.
