SPACE EXPLORATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Gravity keeps the planets in orbit around the sun.
A
True
B
False looked at the night sky through a telescope . Understanding the organization and relationships of the bodies within our solar system requires careful scientific observations and mathematical calculations. As humans explore beyond Earth’s atmosphere, specialized equipment and transportation is required due to the inhospitable environmental conditions that exist in interplanetary space. Due to continued technological improvements to telescopes and other instruments great advances in knowledge have been gained about the solar system and the stars beyond. This knowledge has made it possible for humans to design space suits, tools, and vehicles so that astronauts could safely travel beyond Earth’s surface . Some of the equipment developed allowed astronauts to safely leave the protection of their spaceship for short periods of time in order to conduct repairs to orbiting satellites or to assemble the International Space Station., including the difficulty of safely traveling through Earth’s atmosphere and the engine thrusts need to overcome Earth’s gravitational force . Before developing vehicles that could transport humans, scientists experimented with many unmanned-vehicles. Scientists sent men to the Moon in rockets, satellites into orbit around Earth, and probes into the solar system . For many years the shuttle program took astronauts into orbit around Earth and to the International Space Station. began in 1998. Positioned as a satellite in low Earth orbit, it is a facility for scientists to perform space research and spacecraft testing. In 2012 the first commercial flights to the International Space Station began after the retirement of NASA’s space shuttle fleet. The environmental conditions and vast distances encountered in interplanetary space require specialized equipment and transportation for future exploration and travel.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.

Detailed explanation-2: -The force of gravity pulls a planet toward the Sun. Inertia keeps a planet moving in a forward direction. When the force of gravity balances a planet’s inertia the result is circular motion. A planet needs to be moving at just the right speed to stay in orbital motion around the sun.
