EXPERIMENT INFORMATION

Possible Effects of Zero Gravity on Radiation-Induced Somatic Damage (P-1160)
Principal Investigator
Research Area:
Developmental biology
Radiation biology
Species Studied
Scientific Name: Drosophila melanogaster Species: Fruit fly

Description
Objectives:

To determine to what extent weightlessness may affect the responses of somatic cells to ionizing gamma radiation, immature stages (instar/pupal stages) of the fruit fly were studied in conjunction with space flight and irradiation dose. Highly specialized strains of the fruit fly were developed and later modified to meet the needs of the Biosatellite program.
