A robonaut is a robot designed to assist humans in space exploration missions. As temperatures in space can range from -100 degrees Celsius to 120 degrees Celsius, astronauts need to wear space suits that cost 12 million dollars apiece. They also need at least a few hours of preparation before they

Apogee is a term used to describe the point at which a satellite or object in orbit is at its furthest distance away from the Earth. When an object is at its apogee, it travels much slower than at any other point in its orbit because the Earth has less of a pull on it. By knowing an object’s apoge

What was once only a dream has now become a reality as space travel is a regular activity in our society. With thousands of satellites in orbit, the Hubble Space Telescope that can see other galaxies, regular shuttle launches, and prototypes for vehicles that can fly in and out of the atmosphere, it

Perigee is a term used to describe the closest point at which an object orbits the Earth or another object in space. When an object is at its perigee, it travels faster than it does at any other point in its orbit because it is under the influence of the strongest gravitational force that its source

The law of universal gravitation gives the attraction force between two objects due to gravity. Definition: For any pair of objects, they attract each other with a force that is directly proportional to the product of the masses of the objects and inversely proportional to the square of the dista

Ion propulsion refers to a method of space travel in which accelerating ions, rather than traditional chemical rockets, speed up a spacecraft. While ion propulsion produces very little thrust in comparison to chemical propulsion, it produces consistent acceleration that allows the spacecraft to even

Quasars are a phenomena that, to this day, continue to baffle and confuse astronomers. There are different theories. One is that a quasar is formed from a super, massive black hole. Another theory is that a quasar is actually a baby galaxy and is at the earliest stages of development. However, since

Space mining refers to the planned extraction of mineral content from asteroids, comets, planets, and other heavenly bodies. Astronomers and scientists confirm that a single asteroid could actually hold large amounts of metals and minerals that could amount to billions of dollars in total monetary v
