ISRO and Axiom Space collaborate on critical experiments for the Ax-4 mission prior to launch.

• ISRO and Indian Principal Investigators (PIs) are collaborating with Axiom Space to refresh time-sensitive experimental specimens.

• ISRO has shortlisted seven microgravity research experiments proposed by PIs from national R&D laboratories and academic institutions.

• Experiments include impact of microgravity radiation on edible microalgae, sprouting salad seeds in space, survival, revival, reproduction, and transcriptome of tardigrades in space, effect of metabolic supplements on muscle regeneration, human interaction with electronic displays, comparative growth and proteomics responses of cyanobacteria, and impact of microgravity on food crop seeds.

• ISRO and NASA will conduct five more human research programmes.
