What Key Tech Is Used in Space Missions, Like Docking Systems or AI Navigation?
Space missions are incredibly complex and require advanced technologies to succeed. From launching rockets to landing on other planets, each step uses specialised systems. Key technologies include docking systems, AI-powered navigation, life support, robotic arms, and heat shields—all designed to help astronauts explore space safely and efficiently.
1. Launch Vehicles and Propulsion
- Use multi-stage boosters to increase efficiency
- Powered by liquid or solid fuel engines
Examples:
- NASA’s Space Launch System (SLS)
- ISRO’s GSLV Mk III
- SpaceX’s Falcon 9 and Starship
2. AI Navigation and Onboard Computers
Spacecraft use artificial intelligence and software to:
- Calculate flight paths
- Avoid space debris
- Land autonomously on the Moon or Mars
Examples:
- NASA’s Perseverance Rover used AI to land on Mars (2021)
- ESA’s JUICE mission to Jupiter uses onboard navigation
3. Docking and Rendezvous Systems
- Needs precision sensors, cameras, and guidance systems
- Used in space stations, rescue operations, and fuel transfers
Examples:
- International Docking Adapter (IDA) on the ISS
- SpaceX’s Crew Dragon docks autonomously
- Apollo-Soyuz docking (1975)
4. Life Support Systems
Astronauts need:
- Oxygen supply
- Temperature control
- Water recycling
- Waste management
Examples:
- Environmental Control and Life Support System (ECLSS) on the ISS
- Future Moon bases will use closed-loop systems
5. Communication and Control
- Use radio waves, satellites, and ground stations
- Can send data across millions of kilometres
Examples:
- NASA’s Deep Space Network
- ISRO’s Telecommand and Tracking Centre
- James Webb Space Telescope image transfers
6. Robotics and Arms
Used for tasks too risky or delicate for astronauts:
- Canadarm2 on the ISS
- Dextre robotic hand
- Vikram lander’s robotic payload (Chandrayaan-3)
7. Heat Shields and Re-entry Tech
Spacecraft must survive extreme heat on re-entry using:
- Ablative heat shields
- Materials that slowly burn off to protect the craft
Examples:
- NASA’s Orion capsule
- ISRO’s Gaganyaan re-entry module
8. Scientific Instruments and Sensors
- Analyse soil, atmosphere, radiation, and temperature
- Search for signs of life or useful materials
Examples:
- Raman spectrometer on Perseverance Rover
- Chandrayaan-3 Moon surface temperature sensor
