Science & Technology MCQs

Early and accurate drought predictions enable policymakers to proactively implement targeted water conservation strategies, allocate resources effectively, and provide timely support to affected agricultural communities, mitigating economic and social impacts.

AI algorithms can process vast amounts of data and identify subtle, complex patterns that traditional statistical models might miss, leading to earlier warnings and more precise forecasts of drought onset and severity.

AI-powered drought prediction systems typically integrate diverse data sources, including satellite observations for vegetation health and land surface temperature, meteorological data for weather patterns, and soil moisture sensor readings for ground truth.

ISRO's 2026 announcement indicated that Gaganyaan-2 is tentatively scheduled for a late 2027 launch, following the completion of preliminary uncrewed and crewed test flights.

Gaganyaan-2 aims to validate critical systems for human spaceflight, including advanced life support and crew safety features like the crew escape system, which are crucial for astronaut survival.

The Gaganyaan-2 mission, as announced by ISRO in 2026, is planned as a three-day orbital mission to further test the human-rated orbital vehicle and its systems before the actual crewed flights.

The breakthrough lies in the sophisticated integration of machine learning (a subset of AI) algorithms with massive amounts of historical and real-time meteorological data, allowing the models to identify complex patterns and correlations that were previously undetectable.

Accurate monsoon predictions are vital for India's agrarian economy. These AI models will help farmers plan sowing, irrigation, and harvesting, and aid water resource managers in better allocation and flood/drought preparedness.

AI-driven monsoon prediction models leverage complex algorithms to analyze vast datasets, leading to improved accuracy and the ability to forecast monsoon behavior with longer lead times, which is crucial for agriculture and disaster management.

Semi-cryogenic engines, typically using propellants like Kerosene and LOX, offer advantages such as lower propellant costs and simpler ground handling and infrastructure compared to fully cryogenic engines that use extremely cold propellants like liquid hydrogen.
