1987年SDI的Delta运载火箭将在卡纳维拉尔角发射,至少要进行七种对弹道导弹防御系统非常重要的研究性试验。 约翰·霍普金斯应用物理实验室正在研制卫星载荷,Delta顶级正由麦道公司修改为这次空间试验的关键项目。
In 1987, SDI’s Delta launch vehicle will be launched at Cape Canaveral and will conduct at least seven very important research tests on ballistic missile defense systems. The Johns Hopkins Applied Physics Laboratory is developing satellite payloads and the Delta top is being modified by McDonnell Douglas as the key project for this space trial.
