8 Awesome Pictures of the Surface of Planet Mars
Mars is one of the closest planets to Earth, and we are starting to focus more and more resources on research and observing it. Detailed pictures of the surface of planet Mars are starting to emerge, and it seems as though human exploration of the planet is possible in the somewhat near future. Here are 8 awesome pictures of the surface of planet Mars to give you a better idea of what Mars looks like up close.
How the Space Shuttle Lands: Landing as a Glider
Most of us have seen a space shuttle blast off into space. Using massive amounts of rocket fuel and rocket propulsion, it lifts off through Earth’s atmosphere and into outer space. During lift-off, it loses some of its booster rockets as part of the process, reducing the amount of thrust it has at its disposal. At the end of its mission, the spacecraft re-enters Earth’s atmosphere, with the goal being a safe landing and the safe return of the crew aboard. Yet, without having the engines that a typical passenger jet would have or the fuel to power them once the shuttle enters the atmosphere, the space shuttle seems as though it would be difficult to control and steer during its landing. How does a space shuttle land safely?

Is a Spacesuit Needed to Walk on the Surface of the Moon?
Most people accept the fact that humans have not only reached the surface of the moon, but have walked on it. In all of the pictures from that historic moonwalk, the astronauts are wearing protective spacesuits. Due to the harsh and mysterious environments the astronauts would come into contact with while traveling to and walking on the moon, the need for such protective equipment is no surprise. Yet, if humans were to colonize the moon, and the protective clothing would be much less necessary in their day-to-day lives, would those spacesuits still be necessary?
Cosmic Stardust: Proof Matter Existed Before Earth
There are many who believe that Earth came into existence at (or very near) the same time the known universe was born. However, recent research suggests that this may actually not be the case. Scientists have gathered evidence that indicates solids existed before planet Earth was an actual object. One such piece of evidence is stardust.
