Space Probes – Exploring Space
A space probe is an un-piloted, unmanned device sent to explore space and gather scientific information. Space probes have visited the Moon, asteroids, comets, and every planet in the solar system except Pluto.
What are Space Probes?
An Excellent English writer, now best known for his work in the science fiction genre, says about the Man's quest to know about the Space.
“It is conceivable that some great unexpected mass of matter should presently rush upon us out of space,
whirl sun and planets aside like dead leaves before the breeze, and collide with and utterly destroy every spark of life upon this earth.
It is conceivable, too, that some pestilence may presently appear, some new disease,
that will destroy not 10 or 15 or 20 per cent of the earth's inhabitants as pestilences have done in the past, but 100 per cent, and so end our race.
And finally there is the reasonable certainty that this sun of ours must some day radiate itself toward extinction.
There surely man must end.
That of all such nightmares is the most insistently convincing.
And yet one doesn't believe it.
At least I do not.
And I do not believe in these things because I have come to believe in certain other things – in the coherency and
purpose in the world and in the greatness of human destiny.
Worlds may freeze and suns may perish, but there stirs something within us now that can never die again”.
Astronomers know a lot about the planets of the solar system.
They have detailed maps of planets and their moons.
They even have photographs taken on the very surface of Venus and Mars.
All this information has been gathered by unmanned spacecraft called space probes, which are controlled from Earth.
The information they gather is used to help us understand the weather and other changes which happen on planets other than the Earth.
This information is important in helping to plan other space missions such as ones to Mars and to Saturn.
