The SLS Payload Adapter is 1 of the 2 large-to-medium connectors that officially forms part of the Space Launch System, but can be used on any rocket. It differs from the SLS Universal Adapter by shape, colour and the way it seperates. It is the only flaring that can't be put on top of a payload. Unlike its sister fairing, this fairing separates straight off, instead of clamshell.
