There’s a lot going on in this #spacegif, and most of it is very wrong. So let’s talk about the story behind the failure of the Mercury-Redstone 1 launch. #AvGeek #Spacegeek
Mercury-Redstone 1 was intended as the first unmanned test flight to validate the Mercury capsule and the Mercury-Redstone launch vehicle that would eventually be used to launch Alan Shepard and Gus Grissom’s suborbital spaceflights.
There were 2 electrical cables connecting Mercury-Redstone 1 to the launchpad, 1 for power and grounding and the other for data. At liftoff, the data cable was supposed to disconnect first, followed by the power cable. Instead, the reverse happened.
