Yes but NASA doesn't use the insulated crimp connectors you'll find at your local hardware or auto parts stores and many FIRST Teams do. I should have been more clear that I was referring to those type of crimp butt connectors. Although they exist most people will be unable to locally obtain versions that are properly sized for splicing anything other than 2 wires of the same gauge. Either way the vinyl insulated connectors are next to impossible to determine if they have been properly installed (the "pull" test is not valid and may compromise a connection that was good) and most tools available at the same place that you buy those connectors are not capable of installing them properly. The insulated vinyl connectors are also known for cutting strands of the wire leading to the eventual failure of the wire.
