SpaceX于美國東部時間5月30日下午3：22分將兩位美國宇航員送往國際空間站，雖然這只是Demo任務，但SpaceX已經以其卓越工程優勢、低廉的發射成本贏得了全球航天產業的信賴。同時也是除美俄中這些航天國家隊以外，唯一獨立實現載人航天的商業公司。
成立于2002年，創始人Elon Musk（馬斯克）31歲，歷經18年，期間多次失敗、面臨破產甚至被嘲笑譏諷，其挑戰科技巔峰，降低火箭發射價格，帶動了全球商業航天熱潮，激勵無數青年才俊。SpaceX持續挑戰航天科技與人類想象力，推動全球科技發展，智慧創新，為世界、為孩子、為未來，樹立了楷模。
在馬斯克把火箭送上天的同事，SpaceX的粉絲們把火箭的相關信息也上傳到Github上，沖上了Github的熱榜。
這個開源項目就是SpaceX-API

APi文檔：

Github標星高達5.3k。
這個項目是干啥的？
這批優秀的鐵粉，他們整理的API，基本上包含SpaceX成立迄今的所有火箭數據，包括SpaceX的龍飛船、Starship、發射歷史數據、核心艙、起落架、載荷信息等等，應有盡有。
可以選擇任意一門語言，編寫合適的網絡請求，你即可到json格式的回傳數據,例如你直接在瀏覽器中打開
https://api.spacexdata.com/v3/launches/latest 那么你將會得到以下數據
