So far they&#x27;ve only landed the first stage, not the whole rocket. And they&#x27;ve successfully brought it back to land, but not to the barge, which is what they need for larger payloads (since returning to the launch site requires fuel).<p>And maybe they think by the time they&#x27;re reusing rockets on a regular basis, they&#x27;ll have enough volume to need the bigger factory as well. I don&#x27;t think they&#x27;ve said how many times they expect to reuse each rocket.
