re-usable launch systems

Reusable launch systems are spacecraft or rockets designed to be used multiple times for launching satellites or cargo into space. Unlike traditional rockets that are discarded after a single use, reusable systems are built to return safely to Earth, often landing vertically or on a landing pad. This approach reduces overall costs because the main hardware can be refurbished and used again, rather than building new rockets for each mission. Notable examples include SpaceX’s Falcon 9. Reusability enhances space access's sustainability and affordability by saving on manufacturing and material costs.
