Current and future planetary missions essay

Space exploration has been around for a while however, it has become more of a reality than science fiction.

Space exploration has provided us with knowledge beyond earth and has given us a sign of hope that if Should Space Exploration Be Continued? The Past Instances: There have been a few instances wherein some scientists have claimed that they spotted life on Mars. Along with finding out what kind of life exists in Mars and the kind of atmosphere which is present, there are plenty of other things which will have to be examined as well. However, life on Mars has not been determined to be completely impossible because a larger scope of research has not been done. Yet, with every new frontier they approach, new problems loom over the horizon. Well, new observations and data are essential to our society to advance in the understanding of life and the possibility of life on another planet. Astronomers and scientists have since then been interested in mars and have been trying and striving to learn more about the red planet. Cold and inhospitable. Physical conditions like temperature, atmospheric pressure and climate changes were also determined to be able to sustain life. But given the massive size of the space and how endless it truly is, it surely is likely that there is intelligent life out there. But this miraculous discovery has seeded the life on Mars theory further on. The earth and Mars have a lot of similarities between them. We similarly have low resolution maps of surface composition differences that are frequently ambiguous as to the actual material present. Thereafter, Viking orbiters continued to look for evidence of life. Depending on the wavelengths that the cameras can detect, Saturn may be visible in the images in one of the spectral windows in which the atmosphere is transparent.

Analysis of the radio signals was used to gather information about the electron density of the ionosphere, while temperature and pressure data was encoded in the duration of radio beeps. I find myself almost having a vivid image of the moon landing in even though I would not be born for almost 30 years.

The idea of space exploration has a sense of mystery and excitement about it. Sign Up Message from Sophia! The colonization process requires a lot of resources e. Being above the atmosphere in particular and Earth's magnetic field gives access to the solar wind and infrared and ultraviolet radiations that cannot reach Earth's surface. The next theme addresses the nature of the material in the protoplanetary disk and hence the material that would have been available to build the earliest small bodies. For the past decades, people have sent up men and women, and machines to the space for the sake of space exploration. It is important to note that the atmosphere of mars is very much colder than that of earth. Understanding the real reasons why we are going to such great lengths to find life in space could change the outlook on. The Olympus Mon which is the volcano that is largest and also the mountain that is second highest in all of the big solar system. Chandrayaan-2's Vikram lander is expected to land around Sept.

And as importantly, it provides plentiful supply of waste heat to keep the craft warm on the degree Celsius degree Fahrenheit surface. Otherwise the two missions could not be more different.

The land dug by the rover on mars has led to the discovery that there are three very different types of molecules that are organic on mars and this point to the possibility that there might be the existence of some sort of life or living organism on mars.

Venus and Mars are the two planets outside of Earth humans have conducted surface missions on with unmanned robotic spacecraft.

Future manned space missions

Other scientists believe that water stills exist on Mars but because of its topography and atmosphere it would be salty. Some facts about the planet mars and the earth: It has been discovered that seasonal cycles and period of rotation of the planet earth is very similar to that of the planet earth. Identifying the changes would be a useful scientific byproduct. Once the CAESAR spacecraft acquires its sample, it would quickly move away from the comet to wait for the start of its journey back to Earth. A very popular argument for space exploration is to protect our Earth that we have managed to almost destroy, by finding another planet to retreat to. To explore stars not even in our galaxy and even possibly pull off the feat of discovering extraterrestrial life was something people only dreamed about. Every minute of its potentially many year sojourn at Titan would be spent doing science. Earth provides and sustain living things comfortably. The surface of Titan is too cold for liquid water — the water ice is as hard as rock — but impacts would melt the ice, mixing the hydrocarbons with liquid H2O for as long as tens of thousands of years. Life on Mars is still inconclusive and research is ongoing. Targets of exploration[ edit ] The Sun[ edit ] Although the Sun will probably not be physically explored at all, the study of the Sun has nevertheless been a major focus of space exploration.

Gagarin's flight resonated around the world; it was a demonstration of the advanced Soviet space program and it opened an entirely new era in space exploration: human spaceflight.

Essay on Life on Mars — Essay 4 Words Life on Mars is one of the mysteries that all the scientists in our world have been researching for over decades.

future space missions timeline

ISRO plans to use the experience for more challenging missions in the future, such as touching down on an asteroid or Mars, or sending a spacecraft to Venus, IRSO chair Kailasavadivoo Sivan said in the article.

Due to the relatively high delta-v to reach Mercury and its proximity to the Sun, it is difficult to explore and orbits around it are rather unstable.

Conclusion: In conclusion, no matter how similar mars is to earth, the possibility of human life sustenance is limited. Later much longer duration surface missions were achieved, including over six years of Mars surface operation by Viking 1 from to and over two hours of transmission from the surface of Venus by Venera 13 in , the longest ever Soviet planetary surface mission. While curiosity and the expansion of scientific knowledge are significant factors, the ecological impacts and financial implications of space exploration are the most important factors to be considered when taking up space exploration, as they will have the largest effect on our future. The Sun generates most space weather , which can affect power generation and transmission systems on Earth and interfere with, and even damage, satellites and space probes. It is hard to say that the deck is stacked in either way. Kerim Kerimov was one of the founders of the Soviet space program and was one of the lead architects behind the first human spaceflight Vostok 1 alongside Sergey Korolev. In the Venera 9 was the first to return images from the surface of another planet, returning images from Venus. In as much as we desire life on a different planet, earth is still the best place to be.
