The word I don't get it is "Antriebe". It translates me to "drives, disks" but it doesn't really make sense to me so I hoped some natives could assist :P
The text is about space exploration, inhabiting Mars and/or Moon.

Here is the full sentence:"Müssen dazu erst neue Antriebe oder Baumaterialien entwickelt werden?"

So it goes like:" Do we need to develop new construction materials or (insert Antriebe here)?"
