The test mission deployed a Tesla Roadster into a heliocentric orbit between Earth and Mars, featuring:

• A mannequin ("Starman") wearing SpaceX's next-generation crew suit
• A data storage device containing Isaac Asimov's Foundation trilogy
• A commemorative plaque inscribed with SpaceX employee names

测试任务将一辆特斯拉跑车部署到地球和火星之间的日心轨道，包含：

• 穿着SpaceX下一代宇航服的假人（"星际人"）
• 包含艾萨克·阿西莫夫《基地》三部曲的数据存储设备
• 刻有SpaceX员工姓名的纪念牌

Launch Site Historical Significance

The LC-39AHistoric NASA launch complex at Kennedy Space Center launch complex, leased from NASA, has supported multiple historic space programs including Apollo missions and Space Shuttle operations before being reconfigured for Falcon HeavyA partially reusable heavy-lift launch vehicle developed by SpaceX, currently the world's most powerful operational rocket. operations. 从NASA租用的LC-39AHistoric NASA launch complex at Kennedy Space Center发射场在重新配置用于猎鹰重型火箭操作之前，曾支持包括阿波罗任务和航天飞机运营在内的多个历史性太空计划。

Recovery Operations and Reusability

SpaceX attempted simultaneous recovery of all three first-stage boosters, successfully retrieving two units. The status of the third booster, which targeted an ocean landing platform, remains under evaluation. SpaceX尝试同时回收所有三个一级助推器，成功回收了两个单元。第三个瞄准海上平台着陆的助推器状态仍在评估中。

Orbital Trajectory and Long-Term Mission Profile

Following deployment, the payload will traverse the Van Allen radiation beltsZones of trapped charged particles around Earth before entering a stable heliocentric orbit. According to trajectory projections, the vehicle will maintain this orbit for hundreds of millions of years, serving as a permanent testament to this technological achievement. 部署后，有效载荷将穿越范艾伦辐射带，然后进入稳定的日心轨道。根据轨迹预测，该飞行器将维持这一轨道数亿年，作为这一技术成就的永久见证。
