Experiment DNARM 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:

The experimental hardware includes three separate modules:

  • An irradiation module (UV radiation camera)

The UV radiation camera contains a biological material in NaCl solution (0.9%), which is distributed by four grooves (by 1ml). UV light with a wave length of 375 nm is generated by light-emitting diodes. The bacteriological solution contains nonpathogenic bacteria, which are derivatives of Escherchia coli K12.

  • An electronic control module (with a set of cables)

serves to supply power to the irradiation and ventilation modules, as well as to control the process parameters.

  • A ventilation module
is designed to cool the UV camera, electromagnetic interference filter and voltage regulators of the electronic control module during the process of exposure to radiation.

 

 

PURPOSE:

To study the effect of high level radiation on DNA reparation mechanisms in microgravity conditions.

OBJECTIVES:

To study the UV-radiation effect (375 nm) on bacterium Escherichia coli 12 DNA reparation in microgravity conditions.

EXPERIMENT RESULTS:

Biomaterials exposed to UV radiation and experimental data recorded in the memory module.
