SOLAR SYSTEM

Detailed explanation-1: -rocket. a vehicle shaped like a tube that travels in space.

Detailed explanation-2: -A space probe is an uncrewed vehicle that carries scientific instruments to distant objects in space. Probes carry a variety of data-collecting instruments.

Detailed explanation-3: -A rocket is a vehicle that launches into space.

Detailed explanation-4: -There are lunar (moon) probes, solar (sun) probes that measure solar radiation, and probes that investigate the terrain on rocky planets or the gases on gaseous planets. Introduce the Cassini space probe. Display the web page NASA: Cassini Solstice Mission-Inside the Spacecraft and explore the diagram together.

Detailed explanation-5: -We launch satellites and spacecraft into space by putting them on rockets carrying tons of propellants. The propellants give the rocket enough energy to boost away from Earth’s surface. Because of the pull of Earth’s gravity, largest, heaviest spacecraft need the biggest rockets and the most propellent.

Detailed explanation-6: -Flyby spacecraft conducted the initial reconnaissance phase of solar system exploration. They follow a continuous solar orbit or escape trajectory, never to be captured into a planetary orbit. They must have the capability of using their instruments to observe targets they pass.
