SOLAR SYSTEM

Detailed explanation-1: -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-2: -NASA satellites help scientists study Earth and space. Satellites looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide, and the amount of energy that Earth absorbs and emits.

Detailed explanation-3: -All satellites are launched to space and into their orbit by hitching a ride on a rocket or on the Space Shuttle, where they are placed inside the cargo bay. There are also countries and large corporations that have their own rocket launch facilities, so they can easily send their own satellites into orbit.

Detailed explanation-4: -The Landsat 9 satellite is a joint NASA/U.S. Geological Survey mission that will continue the legacy of monitoring Earth’s land and coastal regions. Landsat 9, a NASA satellite built to monitor the Earth’s land surface, successfully launched at 2:12 p.m. EDT Monday from Vandenberg Space Force Base in California.

Detailed explanation-5: -On October 4, 1957, the Soviet Union launched the earth’s first artificial satellite, Sputnik I. The successful launch came as a shock to experts and citizens in the United States, who had hoped that the United States would accomplish this scientific advancement first.
