...History Venus was formed 4.6 billion years ago along with the Sun and the solar system. Large amounts of dust and gases accumulated over many years to form the planet. Venus is thought to be the result of a large collision. This is due to the fact that Venus rotates differently than the other planets in our solar system. Venus is commonly referred to as Earth's "sister planet" because of their similarity in size as well as a similar gravitational force. Although Venus and Earth share some similarities, it has shown to be very different from Earth in many other aspects. It has the most dense atmosphere out of the four terrestrial planets. Venus consists of more than 96% carbon dioxide. Surface Geography: The surface shows evidence of extreme volcanism, and the sulfur in the atmosphere may mean that there have been some recent eruptions. Venus is covered by a thick atmosphere, creating a blazing environment with temperatures reaching high enough to melt lead. Geology: Much of Venus's surface appears to have been shaped by volcanic activity. Venus is home to about 167 large volcanoes. Some stretching over 100 km long. Venusian surface is estimated to be 300–600 million years old. Almost 2x longer than Earth's. Internal Structure The similarity in size and density between Venus and Earth may mean that they share a similar internal structure: a core, mantle, and crust. Like Earth, the Venus's core is at least partially liquid because the two planets have been cooling...

...r Williams American Studies 104 14 March 2008 Found Voices: Carl Sagan Carl Sagan was perhaps one of the most influential scientific minds that the world has ever experienced. When he learned that stars were actually extremely distant suns, his world was changed and the magnitude of the universe opened up to him. Another strong motivator into science came with his reading of a popular science fiction book of the time, The Burroughs Tales. The stories were not extremely sound scientifically, but still presented ideals of adventure and the unknown. The idea that life could exist elsewhere in the universe fascinated Sagan and remained with him for the rest of his life (Eicher). Perhaps one of Sagan’s most famous individual accomplishments was his involvement with the Pioneer 10 Space Probe. The probe was created to be the first object to exit our galaxy. Sagan acknowledged that the chances of anything actually discovering the probe were astronomical, but believed that it was important to promote public appreciation for science and thought the project to be “all in good fun” (McDonough 50). Public appreciation for science was, in fact, what made Sagan the “superstar scientist” that we hear of today.

...Unit 2 Assignment 2: New Technology in my Field-Research and Essay Nanobots on Mars Nanorobotics on Mars Ryan Robert Smith ITT Technical School Abstract Putting such large equipment on other planets is not altogether as we know the Mars rover Curiosity has made some amazing finds in its short time on the Martian surface, suggesting that Mars was once a wet and fertile planet. Although these findings still in their infancy and not fully substantiated it still gives us time for pause wonder and awe. However one of the main issues with Curiosity is its size. About the size of an SUV which requires more than a million pounds of fuel at an enormous cost to get to the red planet. Limiting its range and over all likelihood to be practical. With curiosity carrying around 165 pounds of research equipment to go even farther would be exponentially expensive. With nanobot technologies not only can we save on costs concerning such explorations, you can also save on logistics. We can send not one or tens or hundreds or even thousands but tens of thousands if not more nanobots out into the solar system at a much more reasonable cost and too many locations. The first nabobs could arrive on mars as a cloud of “smart dust” each one about one-one-billionth of the size of Curiosity. From a drop capsule these sand grain sized robots dropped from an orbiting spacecraft studying or merely passing by the Martian planet dropping them to ride Mars’s lower gravity (about 38% less than Earths)...

...David Corvin 9/9/2012 Managerial Appls of Info Tech Prof. Tahereh Daneshi Course Project Proposal Terraforming Domes and the use of Planet Cracker Mining Vessels We live in a world where one of the main threats to our society is diminishing resources and the inevitability of over population. Humans and animals alike multiply at an alarming rate and with the arrivals of new people to this planet there is a need for aggressive expansion for houses, apartments and retail stores. With new expansion comes the need for new oil and gas refineries and nuclear power plant to support the land that will soon be developed. Human civilization has been consuming natural resources at an exponential rate and the threat that we will soon run out is on the back of our minds. With new developments will come new technology and the need to improve on what we currently have. Our planet can only offer us so much and there is still much to be discovered in outer space. There are hundreds of planets that have the ability to sustain life providing certain conditions are met. NASA or National Aeronautics and Space Administration have been in charge of the space program for many years. While they have released this power to the private sector and given those with the resources a chance to go where they have not offers a potential solution. Terraforming (literally, “Earth-shaping”) of a planet, moon, or other body is the process of deliberately modifying its atmosphere, temperature, surface topography or ecology to...

...terraform a planet. If we could also move humanity to either Mars or Venus, which one should we go for and why? Hi Jessica! Interesting question. To start off, I will define what terraforming is for those who do not know what it means. Terraforming refers to the hypothetical process of modifying a planet or other heavenly body in order to make it habitable by humans. This outcome can be achieved by changing the atmosphere’s competition, the body’s temperature, the surface topography or the planet’s ecology. In order for terraforming to be successful and the planet to be able to sustain life, NASA has defined that such a body must have extended regions of liquid water, favourable living conditions and enough energy sources to sustain metabolism (). Mars is generally understood to be the planet that is closest to fulfilling these criteria because in many respects it is the most Earth-like planet in the Solar System(). It is generally accepted by scientists that Mars once had an Earth-like characteristic including a thicker atmosphere and abundant sources of water. These characteristics have diminished over the course of hundreds of millions of years due to carbon dioxide/carbonates reactions, a lack of magnetosphere and numerous asteroid impacts. The biggest challenges to colonising Mars are low gravity, which prevents Mars from retaining an artificial atmosphere, and the health threat from cosmic rays. Despite this, Mars is ideal for terraforming because it exists on the outer...

...Bittering and his family’s attempt to escape war on earth by building a colony on Mars. This suspense tale shows the effects of the Bittering’s odd new surroundings on Mars. Bradbury’s description of Mars and the Bittering family’s reactions to it give warning that something could go wrong. The atmosphere is one of foreboding and apprehension. Slowly, the circumstances tighten around Harry. The author uses character and plot to express the theme that fear creates resistance to change. I feel that this story is a parable, showing the ways that individuals respond to change, particularly to the environments in which they find themselves. The Bittering family; Cora, Harry, and their three children David, Laura and Dan has arrived on Mars. Initially from Boston, the Bittering family has moved to Mars via rocket so as to avoid the antedated destruction from the war occurring on Earth. However, Harry feels out place on Mars, his new home. His unease is so intense that he wants to return to Earth with his family. He thinks that Mars should only be inhabited by Martians, humans should be back on earth and don’t belong. When a war on earth destroys all space ships and prevents his return, he is determined to build a ship for himself if he is to return to Earth. Bradbury expresses the theme that fear creates resistance to change. From the start of this story, it is evident that Harry vacillates embracing Mars, showing his unease upon landing “…sweat poured from his hands and his face and...

...Events on Mars would have transpired differently if Gallinger had stopped to question his assumptions more. Perhaps the Martian population may not have been saved from extinction, he may have come across the prophecy earlier, and he might not have even brought the prophecy to light at all. If Gallinger had stopped to analyze Braxa’s feelings for him the Martian population may not have been saved. That night when Braxa entered his room, her attention and fascination with Gallinger, along with her willingness to sleep with him made him think that all these events had only occurred because Braxa was in love. Had he taken the time to think, he might’ve realized that before that night Braxa had shown no interest in him nor did she show any afterwards. No proclamations of eternal love had been made by either party, and Gallinger could have easily moved on from Braxa, reevaluating the circumstances to be just a casual fling. This then would have had a large impact on the Martian future. With no emotional attachment to Braxa, Gallinger would’ve finished his work and headed back to Earth, never knowing about his unborn half-human half-Martian child. He wouldn’t have preached his words to the elders, in order to save them from extinction. In fact, he might have been wholly unconcerned with their existence overall. However, Gallinger could have tried to convince the Martians to let them be examined by human doctors to see if it was possible to save the Martian’s existence, but perhaps...

...believe in the possibility of life elsewhere. Over the years, scientists have dedicated a significant amount of their life looking for any type of evidence. There is a great possibility of extraterrestrial life existing on other planets as is evidenced by the history of the universe, the extant research, and the expanse of the universe. The past of the universe substantiates the possibility of aliens living on other worlds. In order to find the proof of life, the scientists have intensely studied planet Mars. About 16 million years ago, the collision of an asteroid with Mars blasted martian rocks in space; Earth’s gravity attracted one of these rocks and it landed in Antarctica. The rock sample from Mars was named ALH84001. Attached to it the scientists found, “fossilized (stone-like) microscopic shapes that strongly resemble living and fossil Earth bacteria” (Nardo 26). It is actually possible that the rock could have contained the bacteria from Mars. The reason is the fact that Mars used...

...avid science researcher, and many of his books and writings clashed with the religious groups. Carl often would talk about life on other planets or solar systems and how could Earth be the center of the Universe if we as a species had never experienced or seen other beings or worlds. The religious sect of society had their negative views of Dr. Sagan and fought to reduce funding of his program on PBS Known as "Cosmos". They eventually won these funding arguments, and the program was discontinued. “Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another ("Good Reads", 2015). Dr. Sagan wrote mainly about his studies of the planets Venus and Mars. The two planets were the closest planets to Earth and maybe could tell a historical event about why they are now uninhabitable to humans. Venus had gone through a traumatic greenhouse effect and had scorched the entire planet. Which is too hot for humans to...

...1. Why has NASA sent recent orbiters to Mars (such as Mars Reconnaissance Orbiter) on trajectories that required them to skim through Mars's atmosphere before settling into their final orbits? | | It saves money because the spacecraft uses atmospheric drag to slow down rather than needing to carry enough fuel to slow by firing rocket engines. | | | Each spacecraft also carried a lander, and the lander could only be dropped to the Martian surface when the spacecraft passed through the atmosphere. | | | It allowed the spacecraft to collect samples of the atmospheric gas for return to Earth. | | | It allowed the orbiters to get higher resolution pictures of the surface as it came close when skimming through the atmosphere. | 2 points QUESTION 2 1. Why was it advantageous for the Voyager mission to consist of flybys rather than orbiters? | | It was easier for data to be radioed back to Earth with flybys than orbiters. | | | Each individual spacecraft was able to visit more than one planet. | | | Spacecraft making flybys can return to Earth more quickly than orbiters. | | | Flyby spacecraft can get closer to a planet than an orbiting spacecraft. | 2 points QUESTION 3 1.
