Shubhanshu Shukla turns farmer in space; grows methi, moong seeds
New Delhi (PTI): In the final leg of his space sojourn, Indian astronaut Shubhanshu Shukla turned into a farmer, taking photos of 'moong' and 'methi' seeds sprouting in petri dishes and inserting them into a storage freezer on the International Space Station (ISS) as part of a study on how microgravity influences germination and early plant development.
Shukla and his fellow Axiom-4 astronauts have spent 12 days on the orbital lab and they are expected to return to Earth any day after July 10, depending on the weather conditions off the Florida coast.
NASA is yet to announce a date for the undocking of the Axiom-4 mission from the space station. The duration of the Axiom-4 mission docked to the ISS is up to 14 days.
"I am so proud that ISRO has been able to collaborate with national institutions all over the country and come up with some fantastic research which I am doing on the station for all the scientists and researchers. It is exciting and a joy to do this," Shukla said in an interaction with Axiom Space Chief Scientist Lucie Low on Wednesday.
The sprouts experiment is led by two scientists – Ravikumar Hosamani of the University of Agricultural Sciences, Dharwad and Sudheer Siddapureddy of the Indian Institute of Technology, Dharwad.
Once returned to Earth, the seeds will be cultivated over several generations to examine changes in their genetics, microbial ecosystems and nutritional profiles, a statement from Axiom Space said.
In another experiment, Shukla deployed and stowed microalgae, which are being investigated for their potential to produce food, oxygen and even biofuels. Their resilience and versatility make them ideal for supporting human life on long-duration missions.
Shukla also captured images for the crop seeds experiment, where six varieties will be grown over multiple generations post-mission. The goal is to identify plants with desirable traits for genetic analysis for sustainable farming in space.
Shukla said his research tasks on the space station spanned various domains and disciplines.
"Right from doing stem cell research and looking at the effect of microgravity on seeds, evaluating the cognitive load on astronauts while they are interacting with screens onboard the station. It has been fantastic. I feel proud to be this kind of a bridge between the researchers and the station and do the research on behalf of them," he said.
"One particular research I am really excited about is stem cell research where scientists are trying to explore whether it is possible to accelerate recovery or growth or repair injury by adding supplements to stem cells. It has been great to work in the Glove Box doing this research for them. I am really excited to be doing this," Shukla said.

TMC leader killed in Bengal's Birbhum
Kolkata (PTI): A local Trinamool Congress (TMC) leader was murdered by unidentified assailants in West Bengal's Birbhum district, police said on Saturday.
Rajbehari Sardar (65), TMC's booth chief in Patisara gram panchayat, was stabbed and severely beaten up by around five-six people at a function in Nanoor area around 10 pm on Friday, a police officer said.
Sardar was taken to Mangalkot Hospital in neighbouring Purba Bardhaman district where he was declared dead by doctors, he said.
The deceased's son alleged that Sardar was killed by members of a rival faction of the party.
The local TMC leadership said Sardar was a committed party worker and was popular in the area, but claimed that there was no report of the involvement of anyone from the party in the murder.
"We demand a thorough and prompt investigation into the incident," a local TMC leader said.
