Discuss India's achievements in the field of Space Science and Technology. How the application of this technology has helped India in its socio-economic development?

Adds human spaceflight progress to a list of India's space achievements; it offers little on socio-economic applications.

• Gaganyaan will send a three-member crew to low Earth orbit for up to three days, making India the fourth country to do so independently.
• ISRO's fifth Integrated Main Parachute Airdrop Test (IMAT-05) on 7 July 2026 qualified the main parachute for the first uncrewed mission, G1.
• The programme uses ISRO-DRDO collaboration (ADRDE, Agra) and uncrewed test flights, including one with a humanoid robot, before crewed flight.

Cite EOS-05 as a recent achievement whose near-continuous imaging serves disaster management and agriculture, the socio-economic uses the question asks about.

• GSLV-F17 launched the 2,367 kg EOS-05 on 4 September 2026, India's first imaging satellite for geosynchronous orbit, about 36,000 km above the Equator.
• It can image selected areas every 5 minutes and all of India every 30 minutes, suiting floods, cyclones, forest fires and crop stress.
• It carries a 42-metre multispectral camera and hyperspectral imagers of 158 channels (VNIR) and 256 channels (SWIR), complementing finer-resolution low-orbit Cartosat satellites.

Cite PRATUSH to show Indian space science moving beyond applications into frontier observational cosmology, with ISRO partnering a research institute.

• PRATUSH (Probing ReionizATion of the Universe using Signal from Hydrogen) is a proposed lunar-orbit radio telescope of the Raman Research Institute, Bengaluru, working with ISRO.
• It shares the goal of the international CosmoCube mission: detecting the faint 21-cm hydrogen signal from the Cosmic Dark Ages, a 'cosmic thermometer' for the era of the first stars.
• Such work could help test ideas about dark matter and the Hubble tension (about 67 versus 73 km/s per megaparsec), placing Indian science at the frontier of cosmology.

Mission Shakti adds India's demonstrated anti-satellite capability to its space achievements, and India's reliance on satellites shows why protecting them matters for development.

• In Mission Shakti on 27 March 2019 India destroyed a satellite with a missile, one of only four countries to have done so, with the U.S., China and Russia.
• India relies on satellites for navigation, communication and disaster warning, so debris-creating tests and weapons in orbit threaten its socio-economic gains.
• China's 2007 ASAT test alone created over 40,000 fragments above 1 cm, showing why India has a stake in binding rules that keep orbit usable.
