It would be an awesome Christmas present if it goes up successfully then.

And the deployment goes successfully.
Indeed so. Hopefully they learned the lessons from Galileo and made extra care to prevent vacuum welding.

Umm what is vacuum welding?
Truth needs no defense.  Nobody can take those footsteps I made on the surface of the moon away from me.

It's when materials bond together spontaneously in a vacuum. It is believed to be what affected the Galileo high-gain antenna, after it lost its lubrication in the long storage between its planned launch date and the actual launch date, preventing it from deploying.

This is a first for me, but it does sound plausible.
