One advantage of sending unmanned missions into space?
It does not have to be brought back to earth and so costs less money
Was there any unmanned space missions on Neptune?
Yes, Voyager II has. (Voyager II is an unmanned space probe).
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.
Pioneer space probe?
The Pioneer space probes are a series of unmanned space missions sent out by the United States for the purpose of planetary exploration.
Did NASA visit Saturn?
NASA has sent several unmanned space probes to Saturn, but no manned missions.
Who was responsible for the Pioneer Space Program?
The Pioneer space program was a series of unmanned missions to explore the planets in more detail. It was a US space program.
What is the manned space program?
The manned space program is just what it says. It's a program to send humans into space. Unmanned vehicles have the advantage in that they don't have to return to earth. That means they can go further and stay in space indefinitely. Manned missions however, need to return its cargo back to earth. Manned missions have the advantage in that if something goes wrong, they can usually fix it in space. If something breaks on an unmanned mission, they simply send up another spacecraft. Manned missions also have the added advantage in that people can observe things in space, while unmanned missions simply obey commands from their earth based masters.

What are manned space missions?
Tasks that are performed by sending people into space, as opposed to tasks performed by sending autonomous or robotic vehicles to do the job.
How is a space probe helpful?
Space probes are sent out on missions to gather scientific data. They are unmanned, which means that they can go farther than a manned shuttle could.
What is the name of one of NASA's space missions?
I am not sure if by "space mission" You mean a mission to a distant object or into deep space or manned or unmanned. Voyager I and II are unmanned deep space missions, both launched in 1977. More than thirty years later they are both still running (as of today: March 10, 2010). The unmanned Mars Exploration Rovers Spirit and Opportunity were rover launched to Mars in 2004. Opportunity is still running fine but Spirit is stationary because two of its six main wheels have stalled. The Apollo Missions were manned moon missions in the nineteen-sixties and seventies. They were also very successful.
Why are most space explorations accomplished by unmanned shuttles?
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.
