Question

Which is an advantage of using space observatories for space exploration?

A. allows scientists to send a crew into space

Answer 1

Space observatories are crucial for space exploration.

Firstly, if you want to launch out of the Earth or any other planet you need to know the alignment of outer space at that time.

Let us think of this situation, you are an astronaut, you have trained for months, on a fine day you get the opportunity  to explore space, you get launched and accidentally you hit a space debri because your space crew was not having a good space exploration telescope (like Hubble) or satellite. Obviously we don't want that to happen.

Secondly if you want explore the outer space you need all kind of observatories of that space like debris(asteroid) exploration, radiation exploration, gravitational exploration(because you would be having limited fuel in your ship).

Thirdly, you need space observatories not only for space but also for earth because you need select a particular time and a particular day on which you would be able to launched off with less effort.

Fourthly, if you want to explore a planet you can't go blindfolded, it's not like slingshot. You need to know the planet's environment, atmosphere, temperature etc. Because in planets like Neptune the temperature would be spin-chilling (Neptune: -214° celsius ). Also in some planets like Mercury the temperature would be grazing heights (Mercury:462° celsius).

Some planets like jupiter have behemoth storms. A spot on Jupiter, which is literally a storm has been there for more than a century.

And also there are many complex aspects like trajectory path of the rocket.

A scientist would allow to send a crew only if it is practically possible. Even though space giants like NASA have big simulators, space varies much faster than those simulations.
