Update: The spacewalk is now confirmed for Monday 21 December.

A mobile transporter got stuck on the outside of the International Space Station and a spacewalk is planned for NASA astronauts Tim Kopra and Scott Kelly to move the transporter to where it needs to be. The spacewalk should last around three hours with the astronauts taking the time to inspect the area and possibly perform more tasks.

The goal is to do the spacewalk on Monday but Tuesday is also a possibility if the earlier date would disrupt science experiments too much.

The decision to do the spacewalk should be taken on Sunday by NASA Space Station officials.

Tim Peake would be heavily involved in the spacewalk as inside support to help his colleagues don their spacesuits and monitor their progress for mission control.
