Not in the foreseeable future.
Humans cannot currently travel to Neptune as it is too far away and sending a crewed mission would be extremely challenging due to the long duration of the journey and the harsh conditions in space. Unmanned spacecraft, like the Voyager probes, have been sent to study Neptune and its moons.
It may be possible in the future, but today we are not able to travel that far.
No humans have visited the planet Neptune.
No
No, humans could not live on Neptune. Neptune's extreme cold temperatures, high wind speeds, and lack of a solid surface make it inhospitable to humans. Additionally, the planet's atmosphere is mainly composed of hydrogen and helium, which are not breathable for humans.
Neptune is a gas giant, so it is uninhabitable to humans.
No, humans have not been to Neptune and there are no known pie vendors on the planet. Additionally, the extreme conditions on Neptune would make it impossible for humans to survive without special equipment.
Have human or human made objects travel to neptune
nope
No, but there is PLENTY of lightning.
No so far no man has set foot on the planet Neptune.
At the present time (2011), there is no program underway to develop a manned mission to Neptune, there is no research being done to advance the technology that it would require, there is no planning being done for such a mission, there is no funding for any research or planning with that purpose, there is no money in the US space program's budget for any activity aimed toward planning or developing such a mission, and at the moment, the US no longer has any ability to launch people into space. So at the present rate, it's liable to be a while.
