This expedition is probably going to be the biggest test yet of their mental and physical strength and experience, and they'll need a good dose of luck as well, from the weather and their health among other things. They will be attempting to climb Manaslu - 8163 m high, I think - on their own, self-guiding, carrying and setting up all their equipment on the mountain, and without oxygen. They have base camp support, so they'll be cooked and cared for at the bottom of the mountain, but above that they'll be on their own.
They flew into Kathmandu last week and for the last few days have been trekking into basecamp, arriving there yesterday. They're hoping to summit sometime in May. You can follow their adventures on Lucille's fantastic blog (ably assisted by Lucille's husband Ted back in Edmonton, Canada). And here's a reminder of ones they did earlier (photos courtesy of Domhnall and/or Lucille):
