Can Mars Support Life? (400-600 words) (20 marks)
• Describe at least two of the requirements for a planet to support (and sustain) life (e.g., water, etc.). Please note that liquid water and temperatures that allow water to be liquid are the same thing.
• Discuss (in detail) TWO pieces of evidence that Mars meets (or met at some time) some of these requirements. Note – I am not asking for evidence of life, just evidence that there was a suitable environment to support life. For each piece of evidence, you have chosen explain: o What was observed? (e.g., ice crystals) o How was it observed? (e.g., satellite images) o What does the evidence prove? (e.g., Mars has water)
• Did Mars have the right conditions to support life in the past? What about now? Ongoing Search for Life (500-700 words) (25 marks)
• In the previous section you proved (I hope) that there is a possibility that life can/could exist on Mars (e.g., Mars has water). In this section you will discuss how we search for life on Mars. If you are confused about the difference between these two sections, please ask for clarification on the Forums.
• Discuss (in detail) TWO of the past strategies used to find evidence of LIFE on Mars 4 o Where have we been looking? (e.g., parts of the planet, meteorites etc.) o What have we been looking for? (footprints, fossils, methane, isotopes etc) o What was observed? o What has worked/failed and does failure mean that there is no Martian life?
• What are the strategies/technologies that various missions will use to search for life on Mars? • What would be the significance if we are successful? Try to justify why we are sending missions to Mars.

Sample solution

Dante Alighieri played a critical role in the literature world through his poem Divine Comedy that was written in the 14th century. The poem contains Inferno, Purgatorio, and Paradiso. The Inferno is a description of the nine circles of torment that are found on the earth. It depicts the realms of the people that have gone against the spiritual values and who, instead, have chosen bestial appetite, violence, or fraud and malice. The nine circles of hell are limbo, lust, gluttony, greed and wrath. Others are heresy, violence, fraud, and treachery. The purpose of this paper is to examine the Dante’s Inferno in the perspective of its portrayal of God’s image and the justification of hell. 

In this epic poem, God is portrayed as a super being guilty of multiple weaknesses including being egotistic, unjust, and hypocritical. Dante, in this poem, depicts God as being more human than divine by challenging God’s omnipotence. Additionally, the manner in which Dante describes Hell is in full contradiction to the morals of God as written in the Bible. When god arranges Hell to flatter Himself, He commits egotism, a sin that is common among human beings (Cheney, 2016). The weakness is depicted in Limbo and on the Gate of Hell where, for instance, God sends those who do not worship Him to Hell. This implies that failure to worship Him is a sin.

God is also depicted as lacking justice in His actions thus removing the godly image. The injustice is portrayed by the manner in which the sodomites and opportunists are treated. The opportunists are subjected to banner chasing in their lives after death followed by being stung by insects and maggots. They are known to having done neither good nor bad during their lifetimes and, therefore, justice could have demanded that they be granted a neutral punishment having lived a neutral life. The sodomites are also punished unfairly by God when Brunetto Lattini is condemned to hell despite being a good leader (Babor, T. F., McGovern, T., & Robaina, K. (2017). While he commited sodomy, God chooses to ignore all the other good deeds that Brunetto did.

Finally, God is also portrayed as being hypocritical in His actions, a sin that further diminishes His godliness and makes Him more human. A case in point is when God condemns the sin of egotism and goes ahead to commit it repeatedly. Proverbs 29:23 states that “arrogance will bring your downfall, but if you are humble, you will be respected.” When Slattery condemns Dante’s human state as being weak, doubtful, and limited, he is proving God’s hypocrisy because He is also human (Verdicchio, 2015). The actions of God in Hell as portrayed by Dante are inconsistent with the Biblical literature. Both Dante and God are prone to making mistakes, something common among human beings thus making God more human.

To wrap it up, Dante portrays God is more human since He commits the same sins that humans commit: egotism, hypocrisy, and injustice. Hell is justified as being a destination for victims of the mistakes committed by God. The Hell is presented as being a totally different place as compared to what is written about it in the Bible. As a result, reading through the text gives an image of God who is prone to the very mistakes common to humans thus ripping Him off His lofty status of divine and, instead, making Him a mere human. Whether or not Dante did it intentionally is subject to debate but one thing is clear in the poem: the misconstrued notion of God is revealed to future generations.

Can Mars Support Life?

Mars, the fourth planet from the Sun, has long been a subject of fascination due to its potential to support life. To sustain life, a planet must meet certain requirements, of which two key factors are the presence of liquid water and a suitable temperature range.

Requirements for Life on Mars

1. Liquid Water

Liquid water is a fundamental requirement for life as we know it. It serves as a solvent for biochemical reactions and is essential for the existence of living organisms. Without liquid water, the chances of life as we understand it are significantly reduced.

2. Suitable Temperature Range

Life, as we know it, requires temperatures within a certain range to thrive. Extreme heat or cold can prevent the existence of complex life forms. A moderate temperature range allows for the stability of water in its liquid form, providing a conducive environment for life to emerge and evolve.

Evidence that Mars Meets Some Requirements for Life

1. Evidence of Ancient River Valleys

Observation: Satellite images and data from Mars rovers have revealed intricate networks of ancient river valleys on Mars.
Observation Method: The Mars Reconnaissance Orbiter and other spacecraft have captured high-resolution images of the Martian surface, showing features resembling river channels and deltas.
Implication: The presence of ancient river valleys suggests that liquid water once flowed on the Martian surface, indicating that Mars had a watery past suitable for supporting life.

2. Detection of Frozen Water

Observation: Ice deposits have been detected at the poles and subsurface of Mars.
Observation Method: Instruments onboard orbiters and rovers have identified signatures of water ice through spectroscopic analysis and radar measurements.
Implication: The presence of frozen water on Mars indicates that water was once abundant on the planet and could still exist in a frozen state today, potentially providing habitats for microbial life.

Past Conditions and Current Suitability for Life

Mars likely had more favorable conditions to support life in its distant past. Geological evidence suggests that liquid water flowed on the Martian surface billions of years ago, creating environments that could have been habitable for microbial life. However, due to changes in its atmosphere and climate over time, Mars is now a cold and arid planet with harsh surface conditions.

Despite the challenging environment on present-day Mars, ongoing research indicates that certain regions, such as subsurface ice deposits or geothermal hotspots, may still offer microenvironments capable of supporting microbial life. The search for life on Mars continues with missions like Perseverance aiming to uncover potential biosignatures and shed light on the planet’s past habitability.

In the next section, we will delve into the strategies employed in the quest to find evidence of life on Mars and the significance of such a discovery for our understanding of the universe.
