One of the most fundamental questions in science currently is whether we are alone in the universe. All the terrestrial planets, such as Mercury, Venus, Earth, and Mars, show evidence of volcanic activities in their past.1,2 Mars is the only location where budgetary and technological constraints permit access and is also considered as having had the most likely planet for sustaining life.1–5 The surface conditions of Mars presently appear hostile to life,6 and thus we rely on evidence that the planet has been more hospitable to life in the past.7 such as the recent discovery of liquid water by NASA's Mars Reconnaissance Orbiter.8
The change to colder and drier conditions may have forced any ancient life to retreat into the subsurface.9,10 Alternatively, while Mars experienced significant volcanic activity, biological remnants may have been absorbed into ancient rocks, and some organic molecules as an indicator of life on Mars may still remain. Thus, the organic matter within the rock potentially contains information that can be used to determine the past or extant presence of life. On this assumption, if we could show that the production of new living organisms or organelles has occurred independently on

This allows us to evaluate methods that will be required to detect past or present life on Mars. In this study, we use analogs on Earth and develop a test procedure with the aim of arriving at a method suitable for analyzing Martian crust
In last couple year’s evidence of water on mars has grown exponentially. The geography of Mars suggests that water was once there. This is because they have found runoff channels in the southern highlands and outflow channels that are almost exact to how they are on Earth, which obviously does have water. The Mars Reconnaissance Observer and Mars Express found deposits of clay in the southern highlands that some researchers say is a strong sign that water was there. Some others argue that the clay could be formed by other elements on Mars, such as wind. Also, the Mars Express detected hydrated’ chemical compounds in the surface of rocks over large areas, which means it
evidence to show that water is in existence today. Looked tidally by Mars are two moons;
Before the sailor flybys in the 1960s, scientist thought Mars had water and life, even if it was just some sort of plantlike lichen. Mars has water, frozen underground and at the polar caps. There is (event(s) or object(s) that prove something) that this water has, in the past and present, flooded the surface in liquid from. Signs of wearing away can be
Most of us are familiar with the panspermia hypothesis – that life can be “seeded” from asteroid, comet, and planetoid contents – but to date, no direct evidence has been discovered. So, why should we consider meteorites to be possible parents? The truth is out there somewhere and these space rocks contain the essentials, as far down as to amino acids. Until now, what has been recovered has been regarded as structured. However, the matter of Tagish Lake arose.
Did you watch The Martian in the movie theaters? It’s hard to make the distinction between science fiction and reality. This paper is dedicated to describing the geology of Mars in reference to our own planet. How do the two planets relate? On a fun note, is there any point in going to Mars? In conclusion, with the power of research, this paper will unlock the mystery surrounded with the geology of Mars.
“I think humans will reach Mars, and I would like to see it happen in my lifetime” was said by Buzz Aldrin, a NASA astronaut. The former American aeronaut from Montclair, New Jersey believes that since Mars does exist, it is waiting to be reached by humans. When this would happen, he says that the human race would “evolve into a two-planet species.” Present day Mars has a lot of canyons, mountains and volcanoes. Even though the surface is Mars is very old, scientists learned about different younger rift valleys, plains, hills and ridges. According to recent reports, there were lakes and rivers, along with an ocean billions of years ago. The low temperatures on the planet cause there to be polar ice caps and frozen water present.
Preview Statement: The possibility of life on mars is an extravagant topic to look at. Before that, we must analyze Mars itself along with its conditions. First, we will talk about the ice caps located on Mars. Second, we will examine the water streaks on Mars. Third we will observe if the red planet is inhabitable for humans to conquer it.
The topic of Mars has long been of interest to astronomers and science fiction enthusiast alike. The premise of another planet supporting life excites people like no other. In 2004, The United States National Aeronautics and Space Administration, or NASA, began preliminary science experiments and instrument proposals for the Mars Science Laboratory (MSL) and a robotic space probe mission to Mars. After long testing and development stages, the mission birthed a rover, Curiosity, which was launched in November 2011 and subsequently landed August 6th 2012. As we speak Curiosity is collecting invaluable data for our understanding of mars including: habitability, climate and geology, and possibly setting up a manned mission to mars in the
Spirit stumbled across rocks that pointed to an earlier, unrulier Mars that was marked by impacts, explosive volcanism and subsurface water [source: NASA Mars]. "Water is key because almost everywhere we find water on Earth we find life," NASA's Web site. However, we are still unsure life existed on Mars.
Mars is the fourth planet in the solar system, and is one of four terrestrial planets that includes Mercury, Venus, Earth and Mars. Mars began its formation 4.6 billion years ago, along with the rest of the solar system. On the surface of Mars, there are large channels that appear to have been carved out by flowing water. Although nothing is certain, there is overwhelming support for the idea that Mars did in fact have flowing water on its surface. There is strong evidence to prove this, hence the channels, but if Mars did have water, where did it all go? Today, Mars is much too cold for water to exists. There is no atmosphere to contain the water if it did exist, so it would go straight from solid ice to water vapor, never reaching its liquid stage (“The Case of Missing Mars Water,” 2001). One theory for the disappearance of water on Mars
NASA’s Curiosity team made history by drilling into ancient rock beds on the planet Mars. This was the first time in human history that such a feat on another planet has ever happened. The Curiosity rover robotically manned by a team from earth chose a basin known as “Yellowknife Bay” to begin its first drilling. The goal for Curiosity will be to enter the basin, obtain a foreign sample of rock and analyze the rock sample. This sample will be chemically analyzed to identify what elements it was composed of and if any organic molecules are still present. This is critically important because the obtainment of this sample may shed light in regards to the existence of water on Mars.
Exploring the universe has gradually become an important mission for many scientists for last few decades. In 1969, the United States successfully finished the first manned mission to the moon. People celebrated and were proud of their abilities. Soon, as the development of technology, scientists are able to reaching further planets in the universe. Mars, as one of the most similar and closet planets to Earth, is the first few planets that scientists are interested in.
These are such exciting contributions, I really can’t wait to see what it can do. Dr. Allwood went through much of what we planning on learning with this mission, including the search for past life. One of the ways we will search for past life is to look at past Mars. They will look for geological clues to find promising targets for the search. NASA wants samples to come back to Earth, for our scientists to be able to use our controlled environment and cutting edge techniques to prepare samples for experimentation. We need to look at the small and the large with this quest for life.
