Because of the cost of sending fuel and re-entry equipment into space, most robotic space probes are designed to do experiments "on site" after landing on a planey or moon.
One exception is the NASA "Stardust" mission launched in 1999. The space craft was launched into a solar orbit that would repeatedly pass near Earth. It was steered into a close encounter with the comet Wild-2 in 2004. Samples from the comet's coma (as well as others from interplanetary space) were returned to Earth by an ejected capsule during a flyby in January, 2006. The craft again passed Earth in January, 2009, enroute to a new photographic mission to the comet Tempel-1 in February, 2011. (Tempel-1 was rammed by the probe Deep Impact in 2005.)
The particles captured by Stardust are still being analyzed from the aerogel material returned to Earth.

Why do you send out space probes insted of actual space flights with astronauts?
NASA occasionally sends out space probes instead of humans because astronauts could not survive on some of the places that space probes are sent to.
Do space probes have astronauts aboard them?
The term "space probe" is normally limited to unmanned (robotic) spacecraft. So, no, space probes do not have people aboard them.
What is the cassini space probes mission?
the cassini space crafts mission was too orbit venus and then observe saturns moons
What space probes provided valuable information about the moon before man's landing on the moon?
Pegasus
What technology does astronauts use?
Astronauts use space shuttles( trasport people and equipment), Space probes (robotic exploration, Spacecrafts (trasport crew, equipment, and other technologies)
What space probes have visited earth?
No space probes have visited earth as all space probes have originated on earth and therefore cannot 'visit' because earth is it's home.
How many times have space probes gone to earth?
Space probes leave Earth, they do not go toit.
What are statellites and space probes?
Statellites and space probes are orbits that go around the Earth. This is to get data.
How does NASA get its space probes back to earth?
NASA gets it's space probes back to earth by computer commands. However. most space probes are not designed for re-entry and remain in space to continuously monitor planets and such.
How fast do space probes travel when launched from Earth?
My answer is that space probes go 5,075 mph, when launched from Earth. Hope I helped you find your answer.
What do space probes travel away from?
The Earth.
How do space probes get information back to Earth when in space?
threw flying Jews
How do we explore space from earth?
We use space probes, and send astronauts... etc.
What are three reasons why we use space probes?
They can go to places that we can't go. They can process and return data to Earth easily. They can study things in space easier because they are clear of the Earth's atmosphere.
How has space technology improved from 60 years ago and how has it helped us in further space discoveries today?
Technology has improved in many ways. Telescopes, Space probes and space shuttle along with many other things help us get a better knowledge of space. More powerful telescopes let us see things very far from earth. Good space probes go more far out in space and are able to learn more about space. Space shuttles do the same thing as space probes but only have humans
Are there space probes going around earth?
Yes, hundreds of them.
What do space probes to send information back to earth?
radio
