Why everyone wants a rocket that comes back

China's LandSpace achieved a significant milestone by recovering its rocket's first stage after an orbital launch. This reusable rocket technology aims to drastically reduce spaceflight expenses and increase launch frequency. Several nations, including the US, Europe, Japan, and India, are actively pursuing similar advancements. India's approach involves a winged spaceplane-like vehicle designed for runway landings. This global competition is reshaping the future of space exploration and commercialization.
