Cowpea Seeds Successfully Sprout in Space

In January 2025, the Indian Space Research Organisation (ISRO) announced the successful sprouting of cowpea seeds in space. This achievement followed the PSLV-C60 SpaDeX mission, which launched on December 30, 2024. The mission included 24 payloads, among which were the CROPS experiment and India’s first space robotic arm.

ISRO’s CROPS Experiment

The CROPS (Compact Research Module for Orbital Plant Studies) experiment is step in space agriculture. Developed by the Vikram Sarabhai Space Centre (VSSC), it aims to understand plant growth in microgravity. The experiment successfully germinated cowpea seeds in just four days. The seeds were grown in a controlled environment designed to maintain optimal temperature and humidity levels. This initiative explores the potential for sustainable food sources in space.

Robotic Arm Technology

ISRO also introduced India’s first space robotic arm, known as the Relocatable Robotic Manipulator-Technology Demonstrator (RRM-TD). This robotic arm is engineered with seven degrees of freedom, enabling it to perform intricate tasks in space. It employs an ‘inchworm walking’ mechanism to move to designated locations on the POEM-4 platform. The arm is equipped with advanced features, including obstacle-aware motion planning and visual inspection capabilities.

Significance of Space Agriculture

The successful sprouting of cowpea seeds marks a milestone in the quest for sustainable life-support systems in space. Growing crops in orbit could support long-duration missions, such as those to Mars. This research will inform future agricultural practices in extraterrestrial environments, potentially aiding human colonisation efforts.

Future Implications for Space Missions

The advancements in robotic technology and plant growth in space hold promise for future space missions. The RRM-TD will facilitate in-orbit servicing and maintenance of spacecraft. It will also provide vital information about how robotics can assist in agricultural tasks on future missions. This technology may be crucial for the Bharatiya Antariksh Station (BAS) and other international collaborations in space exploration.

ISRO’s Vision for Space Exploration

ISRO continues to push the boundaries of space exploration. The successful experiments reflect India’s growing capabilities in space technology. The agency aims to develop indigenous solutions for challenges faced in space, including food production and robotic operations. This aligns with India’s broader vision of becoming a leader in space research and technology.

International Collaboration

India’s advancements in space technology have attracted global attention. Collaborations with other space agencies could enhance research opportunities. Sharing knowledge and technology will be vital for addressing the challenges of living and working in space.

Public Engagement and Awareness

ISRO’s achievements have sparked public interest in space science. Educational initiatives aim to inspire the next generation of scientists and engineers. By showcasing successful experiments, ISRO encourages wider participation in space research.
