Because fundamentally, if a craft is safe to send humans to orbit you want to send humans - not cargo, which is cheaper to send with a craft which is less safe.

- nickff 12y agoYou are correct to say that using a human-rated system to launch cargo is usually much more expensive than necessary, as was true of the space shuttle. This does not mean that the cargo causes any safety problems.
- avmich 12y agoIndirectly, as you have to launch another spacecraft for the same number of people to get to orbit.
