For our next Flagship mission to space, I believe it should be different from the rest of our intergalactic journeys. We have sent rovers and satellites to Mars, satellites to other planets, but we really haven’t gone to far from the norm in today’s space journeys. If we really want to find life on other bodies in our solar system, we have to explore our options. We could explore Jupiter, Venus, Encleadus, or even some of Jupiter’s moons. But what are the main characteristics that are need to sustain life? Water is the most important in my opinion along with the opinion of many other scientists. So what bodies do we know that have the best probability of having water on them? Europa, one of Jupiter’s moons we believe has some sort of ocean …show more content…
We know the crust is solid and most likely water ice due to observations from the probes that have flown by the moon so we know the lander would be able to land and conduct experiments. One of the biggest reasons in which I would send a lander over a human would mainly be because of the cost and the complications. The temperatures alone range from 50-140 Kelvin according to NASA, which is not nearly suitable for humans. Landers are much cheaper than human exploration in the context and generally they are a one-way trip that can experiment longer. Also, Europa has an intense amount of radiation received per day compared to Earth, which would mean that the astronauts would need much better shielding. The extreme conditions and risks associated with deep space travel are beyond what we can handle at this point. We still haven’t even sent a human to Mars, which is .5 AU away let alone sending a human to Europa, which is approximately 4.2 AU away from Earth. We have never sent a human that far out in space due to the unknowns, cost factor, and physical and health concerns. It would be much simpler to send a Lander to Europa for preliminary research to see if it would even be worth sending human explorers …show more content…
One would be to confirm what is under the crust, whether it be water ice or an under the crust ocean containing more than 2x water than there is on Earth according to NASA. If we conclude that there is actually water, then we can either send more instruments or humans to Europa to find out if there is life in the water beneath the crust. This may be a hard task to achieve since the water ice crust is estimated to be 5-20 miles thick according to NASA, which would be problematic, but if we could find a way to figure out if there is water, it could be the greatest discovery in space. Scientists believe that due to tidal heating, it would allow for liquid water to be stable underneath the crust. Tidal heating is when a moon orbiting a planet in an elliptical pattern is compressed and elongated resulting in flexing; this flexing of the orbiting moon produces higher temperatures, which is believed to stabilize the acclaimed ocean beneath Europa’s crust according to NASA. Also, if we found there to be water beneath the water ice crust on Europa, there may be under water processes that are capable of sustaining life like there is on Earth. On Earth, we have deep-water hydrothermal vents called black smokers that produce nutrients to bacteria that sustain life for tubeworms and giant clams and such. It is possible that if Europa contains water that there may be a similar form of chemosynthesis that would sustain alien life forms. To recap
Hercules have you met him? This movie was produced by Ron Clements and John Musker. The movie is about Hercules who is the son of Zeus who becomes a hero. After training with Phil he goes off with Pegasus his flying companion to become a hero. During Hercules journey he goes through 3 parts of a hero's journey.
Heroes, as shown in literature, often undertake the most difficult tasks and place themselves in mortal danger in order to bring back, for themselves and their societies, both knowledge and treasure. Their stories follow “Hero Journey.” The Odyssey, as the epic story of the hero Odysseus, follows closely the complete cycle of a Hero Journey, both as a physical and as a psychological undertaking. The Hero Journey, used as a framework for both Odysseus’ physical and mental journeys, serves to bind the two together. Each of Odysseus’s physical difficulties can be viewed as a metaphor for a psychological hardship that he must overcome, and by overcoming these hardships, Odysseus matures—achieving a more complete understanding of himself and
Every now and then we read different stories, but we see the same things. In the Odyssey and Copper Sun, the two main characters, Odysseus and Amari, shared the same qualities and Epic Hero journeys. They had many obstacles and tribulations, but they worked through them to make it to their destination. Odysseus and Amari have many similarities as well as differences.
All throughout history, heroes from all types of stories have gone through the same journey. Joseph Campbell researched several stories as well as Greek mythology and created a template that every main character or hero follows in each story. Campbell stated that each hero begins his journey in his normal world until he experiences a call to action, which causes the hero to find a mentor and go through several tests and other setbacks until he faces his biggest fear and eventually finishes his quest and returns home. In the Disney movie Hercules, the main character, for which the film is named, follows the journey laid out by Campbell. Hercules follows this journey from his normal life, which he lives until he is called to action and meets
The Astonishing Heroic Journey of Odysseus Odysseus embarks upon the heroic journey which includes many interesting events transforming him into an epic hero. The Odyssey, as the epic story written by Homer which follows the heroic journey. The heroic journey is a pattern of narrative that appears in myth development created by Joseph Campbell.
The planned Europa mission would conduct detailed reconnaissance of Jupiter 's moon Europa to see whether the icy moon could harbor conditions suitable for life. The mission would carry a highly capable, radiation-tolerant spacecraft that would perform repeated close flybys of the icy moon from a long, looping orbit around Jupiter.” this is pretty much it just to see if there 's life and drill a few holes this is what NASA has planned to do with their mission which is in phase two. (Now I haven’t talked two much throughout this and I will give you the reason why I have been working hard on my presentation so hard in fact that most of this is from my presentation and I’m throwing this together last minute to get this done and gone so without further Aude )
With an ice-rink of a surface-just after a ballerina made her rounds-Europa’s surface has a mosaic of crisscross patterns and deep fractures painted across its crater-free face. As the fourth largest moon of Jupiter, Europa is pushed and pulled by the gravity of Jupiter itself, and its other moons. With a surface temperature of approximately -328º F, this moon is seemingly uninhabitable, but in fact, under its mysterious frozen shell could lay an incredible landscape of aquatic life (Astrobio). Hubble’s discovery of enormous water vapor plumes on the South Pole coupled with an analysis of its density and features, it is extremely likely that Europa boasts nearly twice the amount of water of Earth hiding underneath its thick
The Europa Report seems to me to find a good balance between striving to make the film scientifically accurate while keeping it entertaining for the average viewer with basic knowledge about space. I tend to have a lot of willing suspension of disbelief when watching science fiction movies, so as I watched this I tried to pay special attention to the scientific and engineering details used in the mission at hand.
The claim for Europa harboring a liquid ocean could also be explained by the existence of its own unique magnetic field. During NASA’s Galileo mission, the spacecraft observed measurable disruptions in Jupiter’s magnetic field with regards to Europa’s orbit, while also detecting a separate and distinct magnetic field through the spacecraft’s magnetometer (Evidence for an Ocean). Europa’s own magnetic has also raised questions on how it could potentially exist. Scientists have theorized that Europa’s magnetic field alongside the disruption of Jupiter’s could be explained by the presence of a conductive substance below the icy moon’s surface which is believed to be a form of salt water (Evidence for an Ocean). However, like other examples
Other characteristics of life would be much easier to detect with a sensor, and these are the characteristics I would want the space probe module to be able to detect. Firstly, the module would have to detect an atmosphere on the planet, which it would analyze to determine its chemical composition, in hopes of finding high oxygen content to support metabolic processes. Then, the planet’s surface would be scanned for evidence of water to support all cellular functions. Upon the discovery of water, the module would have to scan the surface of the planet looking for regular occurrences of shapes of primitive life forms as we would imagine them to be based on life on Earth in colonies, to possibly indicate reproduction and evolution. Then, a much closer analysis of these shapes must be performed to identify life. A sensor should be able to detect the presence of a phospholipid bilayer for the cell membrane, as that is the cell’s mechanism of regulating what goes in and out of the cell. A sensor should be able to measure the concentration gradient of essential molecules involved in cellular processes, such as oxygen, carbon dioxide, proton gradients created by the electron transport chain and adenosine triphosphate (ATP), which is the cell’s main source of energy. Upon the discovery of all of these fundamental pieces, organelles could be analyzed to search for evidence of DNA to identify
As we all know, Mars has being the darling of NASA for years. But what seemed to be a small moon has now sparked into the eyes of great scientists. Due to the life friendly ocean of Europa the planet is now in the highlights of diverting NASA'S attention from mars. Europa’s water fumes were first discovered by astronomers in January 26th 2014.This lead to the theory of how and why there could be a more
This space-based planetary exploration mission targets the dwarf planet Ceres, which is the mission subject, or more specifically, the surface of the dwarf planet is the subject. The surface of “Ceres is covered in countless small, young craters (Davis, n.d.). “Within some of Ceres' craters, there are regions that are always in shadow. It's possible that without direct sunlight, these ‘cold traps’ could have water ice in them for long periods of time” (Davis, n.d.). The sign of water on the dwarf planet could mean big for the scientists in earth. It suggests a possible sign of life on the dwarf planet. The mission’s objectives are to study the surface of Ceres to find water or signs of water and, if water is found, study the possibility of life on the dwarf planet. A rover will be the payload of the mission, trying to carry out the mission’s objectives. The mission duration will be an unlimited amount of time or until total and permanent communication loss happens with the rover. This mission will ultimately benefit NASA and humankind. These can also be called the mission users.
manned missions to. It also is the planet that we have the best chance of finding life
Future manned expeditions could melt the ice into water, for drinking, washing and turning into rocket-fuel: there is enough ice to make a lake 10km across and 10m deep.
Europa is the sixth of Jupiter's moons and the fourth largest. Europa is named after a Phoenician princess who was abducted by Zeus and taken to the island of Crete to be his lover. Europa was discovered by Galileo Galilei and possibly Simon Marius in 1610 and is one of the four Galilean satellites. The others being: Io, Ganymede, and Callisto. Europa is very different from the other moons of Jupiter. Instead of a rocky, cratered surface like Callisto and Ganymede, it instead has a smooth outer surface of cracked ice. There are very few sign of craters on Europa. In fact, only three large craters have been found. This indicates that Europa's surface is very young and active. In photographs sent back by orbiters, the surface resembles sea ice on Earth. Astronomers believe that beneath this layer of ice may exist an ocean, kept liquid by the moon's internal heat. This liquid ocean could be as much as 30 miles deep. The existence of deep ocean vents on the ocean floor on Earth have led some scientists to speculate that there could be a possibility of life on Europa. Around these deep sea vents on Earth are life forms that do not need sunlight to survive. They instead feed on bacteria that get their nutrients from chemicals seeping up from the ocean floor. This process is known as chemosynthesis. Scientists believe that similar life forms could evolve on Europa if a liquid ocean does indeed exist beneath its frozen surface.
