Indian Institute of Space Science and Technology researchers gear up to study seeds that were sent to space

With Group Captain Shubhanshu Shukla and the rest of the Axiom-4 crew expected back on earth on Tuesday, the Indian Institute of Space Science and Technology (IIST) here is preparing for post-flight field studies using the crop seeds that were sent to the International Space Station (ISS) aboard the high-profile mission.

Post-flight studies will be conducted in collaboration with the Kerala Agricultural University (KAU), which released the seeds for the project, according to IIST sources.

Seeds of Jyothi and Uma rice varieties, Kanakamani (horse gram), Vellayani Vijay (tomato), Thilakathara (sesame) and Soorya (brinjal/eggplant) were sent to the ISS under the ‘Crop Seeds on ISS’, a project spearheaded by the IIST’s Space Biology Lab.

The IIST officials said they expected the seeds to reach Thiruvananthapuram within a few days.

The biology payload consisted of dry seeds that were packed and exposed to microgravity conditions on the ISS and returned to earth. Back on earth, the space-returned samples will be grown to assess the unique effects of microgravity on growth and yield parameters and how it will be manifested in growth.

Comparative studies will be carried out using three sets of samples under different conditions.

The ‘Crop Seeds on ISS’ project was the result of multi-level memorandums of understanding between the ISRO and the European Space Agency, the ISRO’s Human Spaceflight Centre (HSFC) and the IIST, and the IIST and the KAU.

IIST Vice- Chancellor Dipankar Banerjee and HSFC Director D.K. Singh had inked an MoU in this regard in May. K.G. Sreejalakshmi, Professor, IIST, is the Principal Investigator of the project.
