If your kids are early risers, and you want to stall them until a reasonable hour, to open their presents, then this is for you. The International Space Station (ISS) will be passing the United Kingdom at around 6.30am.
Okay, so we know what it is, but imagine your child's delight when they see Santa on his way back to the North Pole, after a busy Christmas Eve.
You might not want to be out in the freezing cold on Christmas morning, but it's the kind of thing that'll make the day that bit more magical, if you do catch a glimpse of the International Space Station.
