任务简介

萤火虫阿尔法火箭的第七次飞行是一次测试飞行，也是该运载火箭在2025年4月发射失败后的复飞。它将在第八次飞行前测试并验证关键系统，为萤火虫的Block II配置升级做准备，该升级旨在增强火箭的可靠性和可制造性。第七次飞行是阿尔法火箭当前配置的最后一次飞行，并将测试多个Block II子系统，包括内部航电和热改进，以积累飞行经验，并在第八次飞行进行全面配置升级前验证经验教训。此次发射还为洛克希德·马丁公司运送了一个演示载荷。

↗ Alpha FLTA007

Firefly Alpha's Flight 7 is a test flight and return-To-Flight for the launch vehicle after its April 2025 launch failure. It will test and validate key systems ahead of Firefly’s Block II configuration upgrade on Flight 8 that’s designed to enhance reliability and manufacturability across the vehicle. Flight 7 is the last flown in Alpha’s current configuration and will test multiple Block II subsystems, including the in-house avionics and thermal improvements, to gain flight heritage and validate lessons learned ahead of the full configuration upgrade on Flight 8. This launch also delivered a demonstrator payload for Lockheed Martin.
