At Earth launch, the landing gear is in a retracted position, and upon operation of the landing gear deployment switch, the landing gear uplocks are explosively released while the springs in the deployment mechanism extend the landing gear. The truss sideframe assembly is a key component in maintaining stability during landing leg deployment.
