航天飞机使用重新设计的固体助推器于1988年9月29日成功地恢复飞行.挑战者号事故之后进行了32个月固体推进工业历史上最广泛的重新设计和鉴定试验.整个过程中进行了大量的试验点火,其数量约为初始助推器鉴定计划期间所做缩比及全尺寸发动机试验的4倍,最后一次试验是1989年1月进行的成功点火. The space shuttle was successfully revived using a redesigned solid booster on September 29, 1988. The Challenger was followed by 32 months of the most extensive redesign and qualification test in the industry's history of solid propulsion. A large amount of pilot ignition was generated, which was about four times the volume reduction and full-size engine test made during the initial booster identification program. The last test was a successful ignition in January 1989.
