Recent pictures of astronauts practicing exit procedures from an Orion spacecraft show the crew hatch's hinge located on the right-hand side of the opening (as viewed from the outside looking in). Yet the hinges were on the left side for the Apollo command module.

Does anyone know why NASA went from Apollo's right-to-left to Orion's left-to-right opening?

It was the way the coin landed.

And here I thought it might be the couch layout inside the cockpit, ergonomic considerations, a sudden preponderance of left-handed astronauts, etc.

I wonder if it might affect whether or not the commander could be chosen to exit before or after the others. No wait, that's only for inward opening hatches!

The exit order from the spacecraft might also depend on whether the commander is from the U.S. Navy.
