INTRODUCTION Space exploration is the investigation of physical conditions in space and on stars‚ planets‚ and their moons through the use of artificial satellites (spacecraft that orbit the earth)‚ space probes (spacecraft that pass through the solar system and that may or may not orbit another celestial body)‚ and spacecraft with human crews.( http://education.yahoo.com/reference/encyclopedia/entry?id=44593) As a senior officer with Malaysia National Space Agency (MNSA)‚ I was invited by the English

present from the evaporation of flowing water. Looking through his telescope Lowell became convinced he could see a network of artificial canals. This led him to believe that there were intelligent beings on Mars who had built these canals. However‚ spacecraft have now visited Mars and found that there is no evidence of water at all. It is now thought that the lines he could see were the combination of Lowell’s overactive imagination‚ and scratches on the lens of his telescope. We are now searching one

existence of Pluto for over thirty years now‚ there are still many mysteries surrounding this celestial body. Being the farthest planet has made it difficult to study Pluto‚ Adding to the obscurity of this strange planet is that the capability to send spacecraft such distances has never been achieved. Through the wonders of science and astronomy‚ there are many things that can be determined‚ concluded‚ and hypothesized about this obscure planet. Pluto’s discovery was actually a fortunate accident.

heat conducted through a bar is The Stefan - Boltzmann law gives the radiant energy emitted or absorbed by an object: Radiation Ex: The sun shines directly on one side of a flat black panel on a spacecraft which has an area of 5.0 m2 and an emissivity of e = 0.95. The spacecraft is located 1.5 1011 m from the sun. How much power does the panel absorb from the sun if the sun is considered to be an ideal blackbody with a temperature of 5700 K? Assuming that the panel can only lose

Earth’s Moon The Earth’s Moon is the most important moon in the solar system in regards to Earth and all of the living things within it. It is also the only Moon that Earth has‚ whereas other planets‚ like Mars‚ have multiple Moons. The Moon is the only other Moon that humans have set foot on‚ which helped us to understand the formation‚ internal structure‚ and history of it. The “moon’s face” is the second brightest thing in the solar system after the Sun‚ and has a dark surface in actuality

The space race‚ a race to see who could make it to space first. It had origin ties to the arms race between America and the Soviet Union. The purpose of this research paper will be to get information on just what the space race was. Along with that‚ the following questions will be answered: What events lead up prior to the space race? What was America’s and the Soviet Union’s involvement in it? And finally‚ what were the end results of the Space Race? What was the space race? It was a competition

that scientist have made wonderful discoveries over time‚ however‚ realistic evidence of proving life existence other than on Earth has not been one of those sightings. Of course there are many individuals that claim that they have seen an “alien spacecraft” or witnessed a “space invasion” and have claimed to have been supposedly abducted by “aliens”. Although what they could have seen could have looked very much like something from another planet because they have no evidence to show what they saw

In a spaceship Astronauts live and work above Earth’s atmosphere‚ so they are exposed to very dangerous levels of ultraviolet radiation they so the spaceship system like earth protects astronauts from UV rays. The spacecraft has special shielding and there are special suits for working outside of the spaceship‚ there’s also special visors to protect their eyes however just like with the atmosphere high energy radiation can still pass through the shielding so Astronauts

The Kepler spacecraft has found over 750 candidates for extra solar planets and that is just from data collected in the first 43 days of the spacecraft ’s observations. This is the biggest release of candidate planets that has ever happened. This is amazing; just imagine if there is that many other planets like earth with human life

ABSTRACT This report aims to measure the pressure variation and different contributing components of the drag force on a circular cylinder. The devices used in this experiment were a fan‚ closed-channel venturi-shape pipe‚ a Pitot tube‚ circular cylinder with holes of different angles‚ U-tube manometers and a barometer. INTRODUCTION When a fluid is passing through an object‚ it produces a total force on the object. This force is a combined force of lift and drag forces (Anderson 2007). External
