Science & Technology Current Affairs - 2026-06-19

Background: India has a robust history of launching communication satellites to enhance connectivity across the nation. These satellites play a crucial role in broadcasting, telecommunications, and disaster management. Current Context: ISRO is reportedly in the advanced stages of planning its next generation of communication satellites, aiming to incorporate advanced technologies like higher throughput capabilities and improved spectral efficiency. These satellites are expected to support the growing demand for data and broadband services. Impact: The successful deployment of these next-gen satellites will significantly boost India's digital infrastructure, enabling faster internet speeds, wider coverage, and more reliable communication services, especially in remote areas. This aligns with the 'Digital India' initiative.

Background: A deep space network is essential for tracking and communicating with spacecraft on missions beyond Earth's orbit, such as lunar or interplanetary missions. India's current capabilities are primarily managed by ISRO. Current Context: To support future ambitious missions like Chandrayaan-4 and potential Mars or Venus expeditions, ISRO is planning a significant expansion of its Deep Space Network (DSN). This involves upgrading existing ground stations and potentially establishing new ones with advanced antenna technology for greater sensitivity and range. Impact: An expanded DSN will enhance India's capacity for independent deep space exploration, allowing for more complex and longer-duration missions. It will improve data reception quality and real-time communication with spacecraft, crucial for mission success and scientific data acquisition.
