Astronaut Down #2

Inter-dimensional astronaut Douglas Spitzer has overshot his destination, and he's now in a world that is both familiar and different. In his home world, a cellular cancer has destroyed 90% of the planet and the people along with it. But this new, parallel world cured it. And while the green sky and clean air is enough to deal with, there's another reason Douglas is hesitant to complete his mission...love.

Meanwhile, mission control has to deal with the fallout from another failed launch and the rapidly encroaching cancer outside, all while trying to aid Douglas - who's the only hope to save their dying world.
