What were the scientific contributions made by Shubhanshu Shukla?

Astronaut Shubhanshu Shukla has completed seven major experiments designed by the Indian scientific institutions under the ISRO’s Human Space Flight Centre during his ISS stay-

1.    Tardigrade Surrvivability

This experiment involved studying the robustness of the Indian tardigrades in the microgravity. 

2.    Muscle Development (Myogenesis)

Muscle loss and tissue regeneration were examined in this experiment. 

3.    Seed germination

Mr Shukla conducted seed germination experiments by cultivating the ‘moong’ and ‘methi’ seeds to assess the farming potential of the space. 

4.    Cyanobacteria research 

Mr Shukla also conducted experiments on cyanobacteria strains on the ISS to study sustainability of humankind in space. Space driven photosynthesis and oxygen generation were also tested for the closed-loop life support. 

5.    Microalgae growth

One of Mr Shukla’s other experiments in the space focussed on micro-algae, tiny organisms that are being explored as a potential rich source of food in future space missions. 

6.    Cognitive performance

In this experiment, cognitive load and its adaptation to the space environments, were measured by Mr Shukla.
