Space Exploration The Space Shuttle The Apollo Missions Visits to Venus Missions to Mars Journeys to Jupiter Voyager
Introduction to Space Exploration
In the years that have followed since Sputnik made its journey into space, human beings have sent space crafts to many of the objects in the Solar System. Unmanned space crafts have landed on the Moon, Mars, Venus and even Titan, one of the moons of Saturn. They have flown closely past all of the planets and sent back detailed images and lots of data about them. They have also visited asteroids and comets and made observations of the Sun. As you sit there reading this now, there are currently rovers exploring Mars, a space craft on its way to Pluto and two space crafts at the very edges of the Solar System.
In addition, human beings have also flown into space. Twelve astronauts in the Apollo mission have walked on the Moon in the 1960s and 1970s, and a small number of people are currently living on a space station in orbit of Earth. The space shuttle was a vehicle which could take astronauts into space and back at regular intervals and was used up to 2011.
All of the missions into space have provided human beings with masses of images and information about the objects that you can see in the sky at night, and even about objects which are so small and tiny that they can't be seen from Earth. This is information that would simply be impossible to obtain by just looking at the objects using telescopes from Earth. But this is only the beginning of the age of space exploration! As technology gets better and human beings get even more adventurous, more and more space crafts will be put into space to make even more discoveries, going further away from Earth and deeper into space. Maybe the first human being to visit Mars is living today and will take a trip there in the not too distant future.
