The photos today are of a GEM-40 solid rocket motor used on Delta 2 and the failure of the launch of GPSIIR-1 (SVN-42). This was the first GPSIIR generation satellite build by LM at Valley Forge, Pennsylvania.
Brief story from Wikipedia:
An investigation determined that the failure was caused by a crack in the casing of the number 2 GEM-40 solid rocket booster (SRB) which started to form at T+6 seconds and grew from there. At T+12 seconds, the SRB casing ruptured and debris struck the number 8 SRB next to it, causing that motor to fail as well. One second later, the range safety destruct charges automatically activated, causing the rocket to auto-terminate, which led to the self-destruction of the first stage and the detonation of the remaining SRBsThe upper stages were blasted free. At T+21 seconds, the Range Safety Officer sent a manual destruct command to terminate the upper stages for safety purposes, resulting in their destruction. The GPS satellite and payload shroud survived intact until impacting the ground. It could not be determined with certainty what had tripped the destruct system on the first stage; possible explanations including a lanyard being pulled, a shock wave from the rupture of the number 2 SRB or heat generated by the event. The booster had been damaged by pressure from a support in a new transportation system that had recently been introduced. Following the failure ultrasound inspections of boosters on future flights were introduced.
