SOLAR SYSTEM

Detailed explanation-1: -Many people use technology to see beyond our planet. Some devices have helped experts look into our galaxy and beyond. One of the first tools for space exploration was the telescope. It gave scientists their first look at what exists beyond Earth’s atmosphere.

Detailed explanation-2: -In general, a spectroscope provides spectral results visible to the eye, for example through an eyepiece on the instrument. Spectrometers and spectrographs use electronic detectors, such as CCDs, and return data representing the intensity of various parts of the spectrum observed.

Detailed explanation-3: -Before 1950, all we knew about the Solar System was from telescopes used on land. That all changed in 1959 with the launch of the first spacecraft to fly by the Moon. Only two years later, the first human went into space and orbited around the Earth.

Detailed explanation-4: -Deep space exploration is the branch of astronomy, astronautics and space technology that is involved with the exploration of distant regions of outer space. Physical exploration of space is conducted both by human spaceflights (deep-space astronautics) and by robotic spacecraft.

Detailed explanation-5: -Space scientists use technology, such as telescopes and robotic spacecraft, to help them make better observations. Robotic spacecraft may fly by or orbit a planet, or they may investigate the surface (landers and sample return missions).
