Although the launch went without any issue, an issue was discovered with the SRB's following recovery. Analysis showed worrying damage to the field joins which was likely caused by hot gases. This similar damage is what caused booster seals abord Space Shuttle "Challenger" to break resulting in a break-up mid-flight. The issue did not compromise astronaut safety because there was a hot gas path through the motors field joint but not the capture joint. Despite there being no issue with safety, it did raise questions of a new EPA required cleaning fluid.
