The Indian Space Research Organisation (ISRO) successfully conducted a landmark 165-second full-power test of its powerful CE20 cryogenic rocket engine at sea level at its facility in Mahendragiri, Tamil Nadu. The CE20 is the cryogenic engine used in the upper stage of the LVM3 (Launch Vehicle Mark 3) rocket, which powers India's heaviest payloads into orbit including Chandrayaan missions. A sea-level full-power test of a cryogenic engine is particularly significant as such engines are designed to operate in vacuum conditions, making the achievement a strong demonstration of ISRO's technical capability. This successful test is crucial for India's upcoming human spaceflight missions under the Gaganyaan programme. The Union Budget 2026-27 has allocated ₹13,705.63 crore for the Department of Space — a 2.16% increase over the previous year's estimate. India is also developing a constellation of 52 satellites over the next five years to enhance space-based surveillance capabilities, while work continues under the Debris Free Space Mission (DFSM) to make all Indian space missions debris-free by 2030.
