Do until the end!!!

For every thing both the earth or Space.
"Maintain the stations and the stations will maintain you. Each Spaceship You is different and figuring out how best to run it over the course of the day, the week, or longer isn't easy. At times you will fail and things will get worse; that happens. But there is no point in berating yourself, there is only one thing to do. Keep the core spinning. Complete the mission. Come back better than before."
