Are Robotic Space Probes the Best Way to Explore the Solar System?

October 19th, 2011

When it comes to exploring the solar system, we are faced with many options. Naturally, the first thing that comes to mind is the usage of robotic space probes for this task. In fact, NASA has worked diligently on this since the 1970′s by sending various space probes across our solar system. Some of the more famously known space probes include the Voyager series as well as the Pioneer series. These space probes have photographed a lot of places in our solar system ranging from the Moons of Jupiter to the rings of Saturn. Even exotic planets such as Neptune and even Pluto has been photographed by these probes.

Especially when distances of couple hundred AU are concerned (1 AU=distance from the sun to earth); it becomes imperative to send robotic space probes to these locations. Especially after Pluto, Kuiper belt starts and this is a region where many asteroids can be found. Even beyond that region we can find the Oort cloud, which is a spherical cloud that is filled with remnants of particles and ice that was formed before the formation of our solar system. Once you pass these, you enter the heliopause, which is actually considered the boundary of our solar system. After the heliopause, our solar system ends and the interstellar void that is made up of gases begins.

How to Plan for the Perfect Mars Mission?

October 19th, 2011

Going to Mars has been one of the biggest dreams of mankind. For centuries, mankind has looked upon the Red Planet with envy, while thinking that it contains a civilization of living beings much like Earth. In fact, until the Pathfinder mission, many people were convinced that Mars contained a much more advanced civilization as compared to Earth. In fact, there were many exposes and scientific papers written on the political structure of the Martian society. However, now we know for sure that no civilization lives on Mars and even the possibility of bacteria or any other non-sentient organism living on Mars is slim if not nonexistent.

Even so, this does not change the fact that sending men to Mars is a viable mission for the future of Earth and for the advancement of space exploration. Mars is the only planet in the solar system that has a viable atmosphere that is susceptible to Terraforming techniques within the reach of our technology. It is a planet that is nearby the general location of Earth and unlike Venus, its atmosphere as well as its surface temperature is more tolerable. Hence, due to this, going to Mars would be a viable and doable mission. Since the Space Exploration Initiative in 1981, Mars has continued to be an attractive mission and as a result both Americans as well as Russians have made plans to go to Mars with a manned flight. However, while this was a matter of prestige for both sides during the Cold war, it has become somewhat of a less important objective after the Cold war has ended.

Terraforming Mars: Fact or Fiction?

October 19th, 2011

There are many words which have been added to the English language through the influence of works of science fiction. For example, one such known word is robot as it has been dubbed by Isaac Asimov in his short stories concerning robots. Hence, it can be said that sometimes science fiction can actually promote science by opening up new visions for scientists to explore. Almost everyone thought that the science fiction stories created by Jules Verne in the 19th century were considered as entertainment; but now in the 21st century, we know that Jules Verne stories have all become a reality. Terraforming is such a concept, as it can become reality, even though it has been stated as a science fiction term in the past.

One of the most viable candidates for Terraforming is Mars. The reason for this stems from the fact that Mars has an environment which is quite amicable to Terraforming. By definition, Terraforming means transforming the habitat of a planet to a new environment, which is capable of sustaining life unaided. Naturally, this is a very bold prospect, but it can be done by employing the right methods and tools from the beginning.
