Have there been manned space visits to neptune?
No, there hasn't.
Is a rocket manned or unmanned?
Could be either manned or unmanned. Rockets have been around since the days when the Chinese invented fireworks, and it's only been since the 1960's that any person was brave enough/crazy enough to ride in one. That's not entirely true; rocket-propelled airplanes have been around since the 1880s. They didn't work all that well, at first..... The vast majority of rockets are unmanned.
How many people have been mars?
No manned missions to Mars have been sent, only unmanned ones.
Has anyone ever been to Venus?
No. Only unmanned spacecraft have been to Venus. The farthest man has travelled is to the Moon. The closest that Venus ever gets to the earth is about 115 times farther than that.In the early 20th century, it was thought that Venus was like Earth but with more water. There are many early science fiction stories that describe the oceans and jungles of Venus. In reality, Venus is almost completely unlike Earth except in size. Several unmanned spacecraft have landed on Venus. All of them were destroyed within hours by the heat and the atmosphere. Several more unmanned craft have done surveys from orbit.The biggest problems with landing a human on Venus are cooling and pressure. It would be the equivalent of building a suit that would withstand the pressure almost a kilometer below the surface of Earth's oceans, while simultaneously being bathed in molten lead.Satellites that have visited the planet included:- NASA Mariner 2 flyby in 1962.- the Soviet (Russian) Venera landers between 1970 and 1985- NASA Magellan (mapped the planet with radar) from 1989 to 1994- ESA satellite Venus Express, orbiting the planet since 2006
Have humans been to Venus?
Not yet, and nobody is likely to for some time. Venus is VERY hot - above 900 degrees Fahrenheit - and has fairly high atmospheric pressure, about 90 times Earth's. The pressure is bearable; humans live in deep ocean habitats at nearly those pressures, and submarines go deeper. But the temperature would be a killer. It will be quite a while before any people set foot on Venus. One proposal that might work is to seed the cloudtops of Venus with a blue-green algae that could metabolize the sulfuric acid in the "air" of Venus, and release water vapor. It might be possible, over a few centuries or millennia, to "terraform" Venus and make it livable.
What is the difference between manned and unmanned spacecraft?
Manned means I has not been around that long and unmanned means around a loong time
Have there been manned space visits to neptune?
No, there hasn't.
Is landing possible on mars?
manned-not until travel time is reduced. There have been unmanned probes.
Has a spacecraft landed on Venus?
There have been several unmanned probes that have landed on Venus, but no people have gone there yet.
What objects have scientists been able to send to space?
All satellites, rovers, manned and unmanned rocketships
What objects have scientist been able to send in to space?

How many missions have been sent into space?
To date there have been 282 manned missions sent into space and more than 1000 unmanned missions.
How does anyone know how hot Venus is if they have never been there?
i think that they have used miniture unmanned probes
Would it be possible to land on venus?
Yes. This has been done by unmanned probes. The first was in 1970.
What engine is used in a rocket ship?
Chemical rockets are generally used on manned spacecraft. Ion propulsion has been used on a few unmanned spacecraft.
