In its first set of biological experiments, the Indian Space Research Organisation (ISRO) will send bacteria cells into space - and bring them back - in the second Space Capsule Recovery Experiment (SRE-2) scheduled for launch this year-end. Two life science experiments, using E.coli and photosynthetic bacteria, will help us understand cell division, genomics (genetic changes) and proteomics (changes in proteins) in microgravity conditions, said Kamanio Chattopadhyay, national coordinator of the Indian Microgravity Programme, who is coordinating scientific experiments for the mission.
