Why Do We Explore?
Why Do We Explore? Lesson Six Why Do We Explore? About This Lesson Students will work in small teams, each of which will be given a different reason why humans explore. Each team will become the expert on their one reason and will add a letter and summary sentence to an EXPLORE poster using their reason for exploration. With all the reasons on the poster, the word EXPLORE will be complete. Students will be using the skills of working in cooperative learning teams, reading, summarizing, paraphrasing, and creating a sentence that will best represent their reason for exploration. Students will also be illustrating and copying other teams sentences so that each student will have a small copy of the large class- room poster for reference or extension purposes. The teacher will lead a discussion that relates the reasons humans explore to the planned and possible future missions to Mars. Objectives Students will: v review the seven traditional reasons why people explore v write a summary of their reason why humans explore v illustrate their exploration summaries v relate the reasons for exploration to the missions to Mars Background Students do not always realize that the steps in future exploration are built on a tradition of Why Do We Explore? exploration that is as old as humans. This lesson is intended to introduce the concept of exploration through the seven traditional reasons that express why humans have always been explorers. Social scientists know that everyone, no matter how young or old, is constantly exploring the world and how it works. Space exploration, including the possible missions to Mars, has opened up a whole new world for us to explore. -

Alluvial Fans As Potential Sites for Preservation of Biosignatures on Mars
Alluvial Fans as Potential Sites for Preservation of Biosignatures on Mars Phylindia Gant August 15, 2016 Candidate, Masters of Environmental Science Committee Chair: Dr. Deborah Lawrence Committee Member: Dr. Manuel Lerdau, Dr. Michael Pace 2 I. Introduction Understanding the origin of life Life on Earth began 3.5 million years ago as the temperatures in the atmosphere were cool enough for molten rocks to solidify (Mojzsis et al 1996). Water was then able to condense and fall to the Earth’s surface from the water vapor that collected in the atmosphere from volcanoes. Additionally, atmospheric gases from the volcanoes supplied Earth with carbon, hydrogen, nitrogen, and oxygen. Even though the oxygen was not free oxygen, it was possible for life to begin from the primordial ooze. The environment was ripe for life to begin, but how would it begin? This question has intrigued humanity since the dawn of civilization. Why search for life on Mars There are several different scientific ways to answer the question of how life began. Some scientists believe that life started out here on Earth, evolving from a single celled organism called Archaea. Archaea are a likely choice because they presently live in harsh environments similar to the early Earth environment such as hot springs, deep sea vents, and saline water (Wachtershauser 2006). Another possibility for the beginning of evolution is that life traveled to Earth on a meteorite from Mars (Whitted 1997). Even though Mars is anaerobic, carbonate-poor and sulfur rich, it was warm and wet when Earth first had organisms evolving (Lui et al. -

It is expected to land on the Red Planet on Nov. 26, 2018. InSight is a mission to Mars, but it is more than a Mars mission. It will help scientists understand the formation and early evolution of all rocky planets, including Earth. A technology demonstration called Mars Cube One (MarCO) will share the launch with InSight and fly separately to Mars. Six Ways InSight Is Different NASA has a long and successful track record at Mars. Since 1965, it has flown by, orbited, landed and roved across the surface of the Red Planet. None of that has been easy. Only about 40 percent of the missions ever sent to Mars by any space agency have been successful. The planet’s thin atmosphere makes landing a challenge; its extreme temperature swings make it difficult to operate on the surface. But if a spacecraft survives the trip, there’s a bounty of science to be collected. -

India to Pull Ahead of China with Mangalyaan's Success
India is set to join the elite list of members after the US, Russia and Europe to have successfully launched termed successful only after the spacecraft manages to insert itself into the Mars orbit on September 21, INDIA TO PULL a spacecraft to Mars. The attempts made by Japan and China (using a Russian rocket) have failed so far. 2014. China had successfully sent two spacecraft, Chang’e 1 and Chang’e 2, into the lunar orbit and is India is banking on its most-successful PSLV rocket, which had put its first spacecraft, Chandrayaan-1, preparing to send a landing and rover mission, Chang’e 3, to the moon in December 2013. Here is a look AHEAD OF into the lunar orbit in 2008. The same rocket flew Mangalyaan on Tuesday.
