This is your one hour warning - if you've ever wanted to go on an extended trip to the cosmos with James Gilmour, at 5pm UK time he's going to be streaming Terraforming Mars over on Twitch.
The game is all about, as you might be able to guess, terraforming the red planet. Don't worry though, James won't be on his own. A couple of the team from Luckyhammers will be joining him on his Martian adventure.
