Space Technology- 6 Video Lecture | Crash Course for UPSC Aspirants

Ans. Space technology refers to the application of scientific knowledge and engineering techniques for the exploration, utilization, and understanding of space. It includes various technologies such as satellites, space shuttles, rockets, space probes, and telescopes that are used for activities like communication, weather forecasting, navigation, remote sensing, and scientific research in space.

Ans. Space technology has numerous benefits for society. It enables communication through satellites, allowing us to make phone calls, use the internet, and watch television. It plays a crucial role in weather forecasting, helping us predict and prepare for natural disasters. Space technology also aids in navigation through GPS systems. Furthermore, it facilitates scientific research and exploration, leading to advancements in various fields like astronomy, medicine, and materials science.

Ans. Some recent developments in space technology include the launch of reusable rockets by companies like SpaceX, which significantly reduce the cost of space missions. There have been advancements in satellite technology, allowing for higher resolution imaging and improved communication capabilities. The development of small satellites, known as CubeSats, has made space exploration more accessible to universities and research institutions. Additionally, the exploration of Mars and the discovery of exoplanets are exciting recent achievements in space technology.

Ans. Space technology plays a crucial role in understanding climate change. Satellites equipped with specialized sensors and instruments can monitor various aspects of Earth's climate system, such as temperature, greenhouse gases, ice cover, and sea levels. This data helps scientists track changes over time and understand the causes and impacts of climate change. Space technology also enables the observation of weather patterns, allowing for more accurate weather forecasting and early warning systems for extreme weather events.

Ans. Space technology development faces several challenges. One major challenge is the high cost associated with designing, building, and launching spacecraft. The harsh conditions of space, such as extreme temperatures and radiation, also pose technical challenges. Furthermore, ensuring the safety and reliability of space missions is a complex task. International cooperation and coordination are essential for space exploration, but geopolitical factors and differing national interests can hinder collaboration. Finally, space debris and its potential impact on future missions is a growing concern that requires effective mitigation strategies.
