Although the launch went without any issue, an issue was discovered with the SRBs following their disassembly in June post-recovery. Analysis showed worrying damage to the field joints which was likely caused by hot gases. Similar damage caused booster seals aboard [[Space Shuttle Challenger|Space Shuttle ''Challenger'']] to break resulting in a [[Space Shuttle Challenger disaster|break-up mid-flight]]. The issue did not compromise astronaut safety because the hot gas path traveled through the engines' field joints but not their capture joint (containing the infamous "O-ring" seals). Despite there being no issue with safety, it did raise questions about the new [[Environmental Protection Agency|EPA]]-mandated adhesive and cleaning fluid.<ref>{{Cite web|url=https://www.americaspace.com/2016/06/18/man-im-here-20-years-since-the-record-setting-mission-of-sts-78-part-1/|title='Man, I'm Here': 20 Years Since the Record-Setting Mission of STS-78 (Part 1)|date=June 18, 2016|website=AmericaSpace|language=en-US|access-date=15 June 2024}}</ref><ref name=prjuldelay>{{cite press release|url=http://www.nasa.gov/home/hqnews/1996/96-138.txt|title=NASA DELAYS LAUNCH OF SPACE SHUTTLE|date=12 July 1996|url-status=dead|archive-url=https://web.archive.org/web/20100223235229/http://www.nasa.gov/home/hqnews/1996/96-138.txt|archive-date=23 February 2010|website=NASA}}</ref>
