SCIENTIFIC RESEARCH ON THE RUSSIAN SEGMENT EDUCATIONAL AND HUMANITARIAN PROJECTS BSM Project CENTENARIO EXPERIMENT SEEDS SE Research Manager: BSA (Brazil)

Experiment SEEDS forms part of the scientific research program performed by Brazilian Astronaut Marcos C. Pontes (BSA) on the Russian Segment of the ISS in the frame of CENTENARIO Brazilian Soyuz Mission Project. The Brazilian Space Agency is a customer of the preparation and implementation of the research program.

USED SCIENCE HARDWARE:

Kit SED consisting of

Kits with seeds SED (4 pc)
SED memory map

USED ONBOARD HARDWARE

Camera Nikon D1у
Laptop A31P

PURPOSE:

Demonstration of gravitropism effects (gravitation change response of plants) and phototropism effects (differences in illumination conditions) on germination of seeds in microgravity conditions.

OBJECTIVE:

To demonstrate the gravitation effect on plants growth to Brazilian students (aged from 10 to 15).

EXPERIMENT RESULT:

Photo information on the seeds germination process in microgravity conditions downlinked from the ISS RS.
Log with information on the seeds growth, memory map, as well as the kits with germinated seeds, to be returned to the ground in the Soyuz TMA descent vehicle.

Four kits with seeds are used in the experiment. Each of the kits contains five seeds Phaseolus vulgaris. Two kits are exposed in the light, the rest kits are exposed in the dark. The seeds germinate at temperatures from +20 to +30°C and at a low oxygen concentration (up to ~3%). Germination process activation is performed through seeds wetting with the use of the attached syringe with water.
The process of seeds germination and evolution is accompanied by photography performed by the onboard camera. The Laptop is used for the following processing of digital photos and their preparation for downlink.
