India’s space programme is opening a bold new chapter. The Indian Space Research Organisation (ISRO) has announced IMEx‑2026. This is a call for proposals from scientists to carry out experiments in microgravity which is the unique and near-weightless environment of space. This initiative marks a rare opportunity for Indian researchers to test ideas that can only be explored beyond Earth, from space biology to materials science. Here's more about IMEx-2026.
What Is IMEx‑2026?
IMEx‑2026, or Indian Microgravity Experiments 2026, is part of India’s larger human spaceflight mission roadmap. Under this programme, scientists can propose experiment ideas that could eventually fly aboard India’s future space missions, including the Bharatiya Antariksh Station (BAS) which is India’s planned space station. This is a gateway for innovative scientific exploration that could have lasting impact in medicine, agriculture, materials and more.
Who Can Apply for IMEx‑2026?
ISRO is inviting principal investigators from academic institutions, national laboratories and industry, including start-ups, to participate. Applicants must demonstrate that their experiment is scientifically meaningful, technically feasible and suitable for microgravity. The goal is to push the boundaries of Indian research into fields impossible to fully explore on Earth.
When to Apply for IMEx‑2026?
Researchers have until 28 February 2026 to submit their proposals. Those selected could become part of a historic era in Indian science, where experiments once limited to lab benches or computers can now be tested in space.
How Experiments Will Be Selected?
ISRO will review proposals on scientific merit, feasibility and potential impact. Promising projects may first be tested on terrestrial microgravity platforms, such as clinostats or drop towers.
The best experiments could then be flown in low Earth orbit, giving Indian scientists a direct foothold in space research. ISRO will also provide technical mentoring and support to help projects succeed.
Where This Fits in India’s Space Journey?
IMEx‑2026 complements India’s Gaganyaan programme, which has already made headlines for sending astronauts on short-duration missions. By involving the scientific community directly, ISRO is ensuring that India’s human spaceflight missions deliver real-world research outcomes.
