On Sept. 16, 1994, astronaut Mark C. Lee tested out the Simplified Aid for EVA Rescue (SAFER) system, a system designed for use in the event a crew member becomes untethered while conducting a spacewalk. Occurring during the STS-64 mission, this was the first untethered U.S. spacewalk in 10 years.

This SAFER test was the first phase of a larger SAFER program whose objectives were to establish a common set of requirements for both space shuttle and space station program needs, develop a flight demonstration of SAFER, validate system performance and, finally, develop a production version of SAFER for the shuttle and station programs.

1994年9月16日，宇航员马克·C·李（Mark C. Lee）测试了EVA救援简化辅助系统（SAFER），该系统专为在宇航员进行太空行走时不受束缚的情况下使用而设计。这是在STS-64任务期间进行的，也是美国10年来首次进行的无系绳太空行走。

此次SAFER测试是SAFER大型计划的第一阶段，该计划的目标是为航天飞机和空间站计划的需求建立一套通用的要求，开发SAFER的飞行演示，验证系统性能，最后为航天飞机和空间站计划开发SAFER的生产版本。
