The photo today is of Athena-1 with the Gemstar 1 payload on the pad at VAFB in 1995.  The mission failed due to two separate failure mechanisms.  The photo came from a public domain photo database (Wayback machine) from NASA archives. Here’s a brief description of the failures from Wikipedia:

On August 15, 1995, an Athena-1 rocket (vehicle DLV), failed during launch. Expended hydraulic fluid burned in first stage aft section, damaging nozzle feedback cables causing loss of gimbal control and tumbling. Separately, arcing in the IMU high-voltage power supply caused loss of attitude reference. Flight terminated by range safety officer at T+160 s.
