    “In the design plans for the system, the word ‘main’ was used inconsistently between the device that sends the electric signals, and the device that receives the signals,” NASA said in a written statement. "On the signal side, ‘main’ meant the main parachute. In contrast, on the receiver side ‘main’ was used as a reference to a pyrotechnic that fires to release the parachute canister cover and deploy the drogue.

    “Engineers connected the two mains, causing the parachute deployment actions to occur out of order,” NASA said.
