Although the shuttle program recently came to an end, there are still many career opportunities in space exploration. There are actually hundreds of different career options in the exciting and imaginative field. Here is a look at some of the more popular areas.

Astronaut
This is probably the first career that people think about when thinking about space exploration. Interestingly, very few astronauts will actually fly into space. They may be involved in other aspects of the job such as space apparatus or orbiter operation. Many astronauts are also involved with public relations aspects of the program.

Rocket Scientist
These are professionals with backgrounds in areas such as astronomy and physics. As the title implies, these people design, build and launch rockets for the space program. Rocket scientists have strong backgrounds in areas such as math and engineering.

Aeronautical Engineer
Similar to the rocket scientist, aeronautical engineers design many different aircraft other than rockets. These engineers have a wide range of career choices. They can work on aircraft, as well as other forms of spacecraft.

Astrophysicist
People who work as astrophysicists have strong backgrounds and knowledge about universe’s physical properties. These people must interpret large amounts of complex data about the universe and space.

Astronomer
These professionals work within the scientific aspects of the universe with regard to its composition, movement, origin and such. The also study planets, stars and other astronomical objects. Much like astrophysicists, these scientists also gather and interpret data about the universe.

There are many other career options for anyone looking for an exciting job in space exploration.

The Mars Rover Exploration Mission

In 2003, NASA embarked on a mission to explore the planet Mars with the use of two land rovers. The primary purpose of the mission was to analyze the past presence of water on the red planet and to see if any water was currently present. The rovers would collect pieces of rock and use specialized equipment to analyze the material. This information would then be sent back to NASA scientists on Earth.

When the rovers landed on Mars, they were deployed from the ship in two different places. One rover was deposited at Gusev Crater and the other was deposited at Meridiani Planum, which was on the opposite side of Mars. Scientists thought this was the best way to get an accurate sample of the rocks and minerals on the planet.

Rover Analyzing Equipment

Both of the rovers were equipped with highly-specialized equipment for the collection of specimens and exploration. Here is a list of some of the equipment.

  • Panoramic camera.
  • Microscopic imager for close-up photos of rocks and minerals.
  • Tools for rock abrasion. This is so the rovers could remove dust and other particles so that they could examine things better.
  • Spectrometer tools to measure thermal emissions and take x-rays.
  • Magnets to collect dust particles that are magnetic.

There was no set ending date for the Mars Rover Exploration Mission as of 2011, and the land rovers will probably never be collected. This was also not the first attempt to explore Mars. Some previous rovers have disappeared or lost contact with Earth for various different reasons. The whole exploration of Mars is going to be a slow process.

The Beginnings of Exploration

It was an age of curiosity — the continents had all been found; the miles had all been sought; and Earth seemed far less impressive than the previous centuries had claimed it to be (with explorers afraid to travel to its edges, certain they would tumble into oblivion). Land no longer held a fascination for the masses. The sun instead appealed, and men looked to the sky for answers to their many questions.

The year was 1958 and space was deemed a challenge to be conquered.

Such a challenge — of course — demanded action; and July 29 saw the creation of the National Aeronautics and Space Act.

Explained simply, the National Aeronautics and Space Act sought to redefine the terms of exploration. Until this time the military controlled all operations regarding the planets; but their influence was too limiting, seeking only ways to develop combat technology (which was deemed far less beneficial to the quest for galaxies). Change had to occur — and it did.

Through the passing of this stature (signed without hesitation by President Eisenhower) separate funding was offered to the cause of the universe; and from this funding rose the beginnings of the National Aeronautics and Space Administration: more commonly called NASA. This sparked the creation of new programs — all with the intention of developing ways to enter the atmosphere and discover what waited beyond.

That intention succeeded: in 1969 man walked on the moon.

Since then the efforts of the National Aeronautics and Space Act have resulted in technological advancements and planetary achievements. These are poised to continue in the years to come.

Our Universe and we

Universe is defined as the totality of everything that exists in the world. Universe includes all the subject matter present around us. The subject matter includes planets, stars, physical matter and energy that surround us. The term universe is also used for bodies like nature, cosmos. The universe is very enormous. The solar system comprises of nine planets which are in the shape of concentric circles. Our universe is infinite and has been growing in size continuously. The concentric circles are of finite sizes and these planets have their orbits rotating around the planet. There are many heavenly bodies and cosmologies that are present in our universe.

There are billions and billions of stars that one sees up in the sky. These are called the Milky Way and there are many other galaxies that exist around it. There have been several other kinds of radiations like the red shift which is present in the universe. The size of our universe has expanded because of certain cosmic inflation. This cosmic inflation affects diverse kinds of forces.  National Aeronautics and Space Administration has been making numerous researches to help us know more about our universe.  Many of these researches highlight the fact that the universe is expanding day by day. The observations made in the recent years show that the reason for expansion can be attributed to the dark energy present in the atmosphere. Dark energy is responsible for the inflation in the universe.

The astronomical observations show that the age of the universe is more than 13.75 billion years and their diameters have expanded by leaps and bounds over the past few years. The scientists and researchers have expressed the fact the space is expanding at faster rate as compared to the speed of light. It has now become very difficult to indicate the size of universe as it is not very easy to measure it.
