| Summary | Rocket Lab's medium-lift reusable rocket targeting the $100B constellation replenishment market. Uses a 'hungry hippo' fairings design that opens at the top rather than traditional clamshell separation. First flight delayed to Q4 2026 after a Jan 2026 propellant tank test anomaly. | China's most powerful operational rocket and the backbone of its flagship space programs. Launched Tianwen-1 to Mars, Chang'e 5 sample return, Chang'e 6 far-side sample return, all Tiangong core and lab modules, and the Xuntian space telescope. The CZ-5B variant delivers entire station modules in a single flight. | Europe's dominant heavy-lift rocket for 27 years. Its most famous payload: the James Webb Space Telescope (Dec 25, 2021). Retired Jul 5, 2023 to make way for Ariane 6. Responsible for launching over 250 commercial and scientific payloads including XMM-Newton, Rosetta, and BepiColombo. |
