Space Technology 

Space technology refers to the tools, systems, and scientific advancements used for exploring, understanding, and utilizing outer space. This includes everything from rockets and satellites to space stations and deep space probes.

Key Components of Space Technology

1. Launch Vehicles (Rockets):
   Used to carry spacecraft, satellites, or astronauts into space.
   Examples: SpaceX Falcon 9, ISRO's PSLV, NASA’s SLS

2. Satellites:
   Orbit Earth or other celestial bodies to support communication, weather monitoring, navigation, and research.
   Types: Communication satellites, Earth observation satellites, GPS satellites.

3. Spacecraft & Probes:
   Vehicles used for human spaceflight or robotic exploration of planets, moons, and asteroids.
   Examples: Mars rovers (Perseverance), Voyager probes, Artemis spacecraft

4. Space Stations:
   Habitable platforms in space where astronauts live and conduct research.
   Example: International Space Station (ISS)

5. Space Telescopes:
   Devices like the Hubble or James Webb Space Telescope that capture high-resolution images of distant galaxies and stars.

Applications of Space Technology

• Communication: Satellite phones, TV broadcasting, internet (e.g., Starlink).

• Navigation: GPS, Galileo, NavIC for accurate location services.

• Weather & Climate: Satellite imagery for weather prediction and climate monitoring.
