Is an hour in space 7 years on Earth?
The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.
How much do astronauts get paid?

What happens if an astronaut gets pregnant in space?
For one, without the stress of Earth's gravity, her bones lose density. Studies show that astronauts, for instance, lose 1% to 2% of their bone density for every month spent in space, and that would be especially concerning for giving birth because the pelvis could fracture in the process.
