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 technology does astronauts use?

Astronauts use space shuttles( trasport people and equipment), Space probes (robotic exploration, Spacecrafts (trasport crew, equipment, and other technologies)


What do astronauts wear to survive on Mercury?

Astronauts don't go to Mercury it's too hot and they could send probes or spacecraft there much more cheaply, safely, and easily if they really needed to.


How do astronauts take pictures?

We send satellites and space probes equipped with cameras into space. The satellites and probes can be sent commands via radio waves, and the equipment then sends back digital photographs via radio as well.


What do astronauts fly in?

Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit. When astronauts travelled to the Moon, another smaller rocket pushed the Apollo spacecraft out of orbit, and carried it to the gravitational field of the Moon. Another rocket firing pushed the craft back to Earth. Unmanned space probes have travelled to even farther distances from Earth, including the outer planets Uranus and Neptune. Most of the travel is coasting, because there is practically no matter in space to slow a spacecraft down.

Why have you sent probes instead of astronauts to explore the distant areas of the solar system?

Simpler and cheaper.

Do space probes carry humans?

No, space probes are unmanned spacecraft designed to explore the cosmos without the need for human presence aboard. They are equipped with scientific instruments and communication systems to gather data and transmit it back to Earth. Manually controlled missions with astronauts on board are categorized differently and are not considered space probes.


Are there any manned space probes in space?

As of now, there are no manned space probes in space. All probes sent beyond Earth's orbit are unmanned and controlled remotely from Earth. Manned missions have been limited to spacecraft that carry astronauts, such as the International Space Station or missions to the Moon.
