Are asteroids made out of other stuff than everything else is mad of?

“Are asteroids made out of other stuff than everything else is mad of?”

The main thing is that the stuff is “up there” already. Some of it could be useful for large space missions. That could save a lot of money.

Yes, asteroids are made up of universal chemical building blocks. For example some are iron, some are Hydrogen Cyanide ice.

Would be bad to lasso the wrong one, specially bad if it crashed. The iron ones would leave a big hole, the cyuranic acid types would poison the planet.

But only for oxygen breathers...
