What technology can create water on an airless, desert planet?

Planet has these characteristics:

• Half of the planet is always on day, and other half is always night (it rotates at the same velocity as its orbit)
• There are no underground water sources; it's all dry.
• There is no atmosphere. (I don't know if there can be atmosphere without water or any other liquid/gas.)

The tech to make water must meet these constraints:

• Humanity has some advanced technology compared to today, enough to travel through interstellar space. Answers can advance human tech level to suit the purpose of making water, but the less advanced necessary, the better.

• The technology has to be on the space ship. This space ship can be enormous.

  Basically, humanity just made Earth uninhabitable so they need to escape. Every country makes their own spaceship and selects a planet they think will support life.

  Something end wrong: one of the ships crashes on a desert planet. The humans are now confined there for at least a couple of centuries while they develop the manufacturing base to repair the spaceship.

  They can live in the spaceship, but they need, for whatever reason, to make water.

  Can they manufacture water? If so, how?
