Several advantages; mainly:A human needs food, air, and protection. An unmanned craft needs none of these; its use of energy and other "extras" is much less than for a human.An unmanned craft can be sacrificed; there is no moral obligation to return it safely to Earth.In summary, all this makes an unmanned spacecraft much cheaper than a manned spacecraft.
With today's technology, travel time for an unmanned probe or unmanned small spacecraft is about 9 years. If you are talking about a ship that transports humans, we don't know.

Unattended machinery space (Unmanned operation E0). Conformity is tested during sea trial.
Which second ship? and whose? American? Russian? British? Manned? Unmanned? More info please for better answers!!
they are larger
they are larger
This is because sending men up into space costs a lot more money than sending probes or other unmanned space craft. When you send a crew of people up you need to provide their living space, food, air, etc so they can survive. Holding all that would make the ship larger and cost more than a smaller unmanned ship. Also unmanned crafts can travel longer distances. No human wants to go on a 10 year journey where they might end up killed, these droids can do this for them.
There are no people on it. That means it is unmanned.
