Indian Astronaut Shubhanshu Shukla Returns from ISS; Researchers to Study Space-Sent Seeds

Indian astronaut Group Captain Shubhanshu Shukla and his Axiom Mission 4 (Ax-4) crew departed from the International Space Station (ISS) after 18 days, completing seven microgravity experiments. The Dragon spacecraft is expected to splash down off the California coast. Meanwhile, the Indian Institute of Space Science and Technology (IIST) is preparing for post-flight field studies on crop seeds (Jyothi and Uma rice, horse gram, tomato, sesame, brinjal) that were sent to the ISS under the "Crop Seeds on ISS" project. These seeds will be grown to assess the unique effects of microgravity on growth and yield, with comparative studies planned.
