Essay on Life on Mars: Characteristic similarity and proximity from Mars to Earth has made the possibility of life on Mars a favourite subject amongst space scientists. There are as many cons to this subject. Harsh weather conditions, colder temperatures, water scarcity and lack of ozone layer indicate the difficulty of sustaining life on Mars.
Essay on Life on Mars 500 Words in English
Below we have provided Life on Mars Essay in English, suitable for class 6, 7, 8, 9 & 10.
Our solar system consists of eight planets revolving around the sun. The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune revolving around the sun in the respective order. Earth is the 3rd planet in the solar system starting from the sun, which is the only planet in the solar system known to have life. Mars is the 4th planet starting from the sun & the second smallest by size. It is also known as the red planet because it appears as an orange-red star in the sky.
Life on Mars has been a massive topic of interest for research by the scientist. The possibility of life on Mars has been aroused by its proximity & similarities to the Earth. However, until now, no life has been discovered on the planet, but certain proofs indicating past life in Mars has been validated, which has undoubtedly gained enormous interest in astrobiology.
Probability of Life on Mars
The first evidence of life on Mars has been highlighted in the early 19th century, since then scientists, and astronomers are carrying out a number of experiments & studies to assess the habitability of the planet. The research is also focused on the possibility of life on Mars in the past. When searching for life water in the liquid state is critical, as most life forms evolve around this. Experts believe that the planet was once covered with a vast ocean which accounts to be more than what we have in Earth today.
Which, in turn, indicates that streams of water, rivers may have flowed in the past. It is believed to be much warmer than it is currently. Most optimum temperature & water is one of the basics which gives rise to the existence of life, so there is a high possibility of life on Mars in the past. Furthermore, life is existing in Earth in some extreme conditions like cold regions, hot springs, etc., so giving hope for the existence of life on the planet.
Presence of methane on Mars has forced scientists to think about the possibility of microbes under the surface. By the analysis of small pinches of soil from the planet, experts predict that there may be refugee life deep inside the planet’s surface.
Challenges of Life on Mars
Although there are past pieces of evidence of the presence of water in liquid form, today the planet is found barren & dry with most of its water locked up in the polar ice caps. As the water in liquid form is key to life, here it poses a problem for the same. The climate of the planet is another significant problem. The temperature of the planet is much colder than that of Earth, i.e. the mean surface temperatures of Mars range between −87 and −5 °C.
The planet’s atmosphere is thin, which poses another significant challenge as it allows the harmful radiations from the sun to penetrate. The environment & atmosphere is harsh & extreme to survive, although oxygen is found in the atmosphere of all over the planet. The lower atmospheric pressure & gravitational force of the planet is another hurdle for life on Mars.
Life on Mars is a topic that has attracted a lot of attention & curiosity among scientists & experts. Although there is still no full assurance of whether Mars will be able to support life like Earth fully. However, with the hope to explore Mars for the possibility of life, a lot of research & studies are still going on to discover the same.
