The plan is for technicians to visually inspect the exterior of Engine No. 5, which is in the center position in the tic-tac-toe pattern of engines on the Falcon 9 first stage.
The team may also conduct boroscope inspections of the thrust chamber, but Shotwell said SpaceX is hopeful the engine will not need disassembly or replacement. Removing the engine adding a fresh unit would take several days.
The plan is for today's inspections to be conducted while the 15-story booster remains in a vertical position atop the launch pad. The Falcon 9 may be lowered and moved back into the hangar later to protect the rocket and Dragon spacecraft from weather conditions until another launch opportunity nears.

Gwynne Shotwell, president of SpaceX, says technicians will inspect Engine No. 5 on the Falcon 9's first stage beginning at around 12 p.m. EDT (1600 GMT). Further data analysis of readings from the engine during the ignition prompted SpaceX to order hands-on inspections before clearing the rocket for liftoff.
The next launch opportunity is still Tuesday at 3:44 a.m. EDT (0744 GMT), but that is pending the outcome of today's inspection.
Shotwell said the abort was triggered one-half second before liftoff after all nine engines were ignited.
Alan Lindenmoyer, NASA's commercial crew and cargo manager, said there should be another launch opportunity May 23 at 3:22 a.m. EDT (0722 GMT).
