Background: Following the success of Chandrayaan-3, ISRO initiated the Chandrayaan-4 mission aimed at bringing lunar soil samples back to Earth. Current Context: On April 18, 2026, ISRO successfully completed the vacuum chamber testing of the 'Ascender Module.' This module is designed to launch from the lunar surface and dock with the orbiter in lunar orbit. Impact: This achievement marks a critical step in India's complex multi-launch mission strategy. It places India among a select group of nations capable of extraterrestrial sample return, significantly boosting India's stature in deep-space exploration and planetary science research.

Background: The National Quantum Mission (NQM) was launched by the Government of India to develop intermediate-scale quantum computers and secure communications. Current Context: On April 17, 2026, the Department of Science and Technology (DST) announced that Indian scientists have successfully operationalized a 100-qubit quantum processor using superconducting circuits. This is a massive leap from the earlier 8-10 qubit prototypes developed in 2024. Impact: This development will accelerate indigenous research in drug discovery, financial modeling, and cryptography. It reduces India's dependence on foreign quantum infrastructure and enhances national security through the development of quantum-safe communication protocols.
