Understanding Space Mission Classifications

Human Spaceflight

Missions designed to carry astronauts beyond Earth orbit. Current programs include NASA's Artemis (Moon missions), SpaceX's Starship (Mars target), and China's planned lunar missions. These require life support systems, radiation protection, and return capabilities.

Planetary Science

Unmanned missions to explore other planets, moons, and asteroids. These include rovers like Perseverance on Mars, orbiters like Europa Clipper, and flybys. They're designed to maximize scientific data return within strict mass and power constraints.

Astronomy Observatories

Space telescopes like James Webb observe the universe from above Earth's atmosphere. JWST specifically studies infrared light from early galaxies, allowing us to see further back in time than ever before.

Commercial Constellations

Large satellite networks like Starlink provide global services from low Earth orbit. While offering benefits like global internet, they raise concerns about space debris and impact on astronomical observations.
