LunaRoo: Designing a Hopping Lunar Science Payload #space #exploration
Presentation slides from the talk given at the IEEE Aerospace Conference (@IEEEAeroConf) 2016 in Big Sky, Montana, USA.
We describe a hopping science payload solution de- signed to exploit the Moon’s lower gravity to leap up to 20m above the surface. The entire solar-powered robot is compact enough to fit within a 10cm cube, whilst providing unique observation and mission capabilities by creating imagery during the hop. The LunaRoo concept is a proposed payload to fly onboard a Google Lunar XPrize entry. Its compact form is specifically designed for lunar exploration and science mission within the constraints given by PTScientists. The core features of LunaRoo are its method of locomotion – hopping like a kangaroo - and its imaging system capable of unique over-the- horizon perception. The payload will serve as a proof of concept, highlighting the benefits of alternative mobility solutions, in particular enabling observation and exploration of terrain not traversable by wheeled robots. in addition providing data for beyond line-of-sight planning and communications for surface assets, extending overall mission capabilities.
Class Paper
The universe began approximately 13.8 billion years ago from the expansion of gases and particles that eventually formed into stars and planets through gravitational forces and nuclear fusion. The present day universe is expanding at an accelerated rate due to dark energy and dark matter. It is predicted that the universe will end in one of three scenarios - the Big Rip where expansion becomes infinite, the Big Crunch where the universe collapses back on itself, or the Big Freeze where the universe grows too cold to support life.
Our solar system
This document outlines how to use the Big6 research process to integrate multimedia into a science curriculum. It provides templates for each step of the Big6 process, including task definition, information seeking strategies, locating and accessing resources, using information, synthesizing results, and evaluating work. Students would use the templates to guide a research project on the planets, developing a multimedia slide show presentation summarizing key facts about each planet and including a bibliography. The Big6 process provides a framework for students to effectively find, use, and present information through an integrated multimedia project.

This document summarizes information about observing the moon, including definitions of key terms, background facts about the moon and its orbit around Earth, and questions about why we can sometimes see the moon during the day. Resources are provided on definitions, images, and additional reading on lunar sightings.
Go to mars
The document outlines some of the health challenges astronauts may face on a mission to Mars, including a long journey in space, difficulty adjusting to Martian time zones, lack of access to medical facilities on Earth, potential infections from Mars, exposure to high radiation, and effects of low gravity on the body. It provides a website for more information on how sick astronauts could be treated upon returning to Earth and encourages the reader to learn more about NASA's Mars project by visiting their website.
1.12 how did the universe begin
The document discusses evidence that supports the Big Bang theory of the origins and evolution of the universe. It describes how observations of distant galaxies provided evidence that the universe is expanding from an initial extremely dense and hot state around 13.7 billion years ago. It also mentions how the cosmic microwave background radiation provides major support for the Big Bang theory and how computer models are used to simulate galaxy formation from the early universe.
Theories of the universe
The document discusses different theories of the universe including the Big Bang Theory and the Biblical Creation theory. The Big Bang Theory states that the universe began as a very small, dense point that exploded, expanding into the universe we see today. The Biblical Creation theory states that God created the universe and humans in six days according to the Bible. The document concludes that while it cannot be proven, the most reasonable theory based on available evidence is the Big Bang Theory.

Black holes FyQ
Scientists have three theories about the formation of black holes: 1) the smallest may have formed at the beginning of the universe, 2) the largest, called supermassive black holes, formed alongside the galaxies they reside in near the Big Bang, and 3) stellar black holes are created when large stars collapse in supernovae. Black holes have extreme gravity that warps spacetime, with theories that anything entering one would be instantly destroyed or may pass through unharmed.

Nestea Iced Tea, Marketing Strategy
This document provides an overview of a marketing campaign for Nestea powdered iced tea. It outlines research conducted including consumer interviews and store visits. It identifies teens and young adults as the target market. The problem is that Nestea, as a mature brand, risks becoming taken for granted. The objectives are to refresh Nestea's brand image and revive interest among teens and young adults. The proposed "Rewind" campaign idea celebrates Nestea's 30th anniversary in the Philippines and revives its positioning as a refreshing beverage. Suggested executions include flash mobs, on-campus dance challenges and promotions, and an interactive installation providing refreshing mist and drinks.
Origins Of The Solar System
The solar system formed from a large cloud of dust and gas that collapsed under gravity around 4.6 billion years ago. As the cloud spun, it flattened into a disk with the sun at the center. Closer to the sun, the rocky, terrestrial planets Mercury, Venus, Earth, and Mars formed. Further from the sun, the larger gas giants Jupiter, Saturn, Uranus, and Neptune formed, along with the icy planet Pluto. The inner planets are smaller and denser, while the outer planets have thick atmospheres and are mostly made of gas.
Proficiency 4 astronomy science
The document summarizes key information about the solar system. It describes the inner and outer planets, with the inner planets being terrestrial and the outer being gas giants. It explains that astronomers believe the sun formed from a rotating gas cloud that over time became a star through nuclear fusion. It also notes that the sun is about a third of the way through its lifespan and will eventually expand and shed its outer layers to become a white dwarf.

In the future, the sun will grow brighter, and space travel may include vacations to Mars and the moon.
The Solar System
The solar system formed over 5 billion years ago from a collapsing cloud of gas and dust called a solar nebula. As the nebula rotated and flattened, larger objects called planetesimals formed and collided, eventually creating the planets. At the center, the sun formed. The inner planets Mercury, Venus, Earth and Mars are small, rocky bodies close to the sun. The outer planets Jupiter, Saturn, Uranus and Neptune are much larger and mostly made of gas. Technology like satellites and space telescopes continue to provide more information about the solar system to further our understanding of the universe.
Introduction to Earth Science
This PowerPoint briefly describes the 5 branches of Earth Science. This presentation is meant for an 8th grade science course.
The oort cloud and the kuiper belt2
The Oort Cloud is a theorized spherical cloud of predominantly icy planetesimals believed to surround the Sun to as far as halfway to the nearest star. It is thought to be the source of long-period comets. The Kuiper Belt is a disc-shaped region beyond Neptune's orbit populated by numerous icy bodies and extending from 30 to 50 AU from the Sun, including short-period comets and objects like Pluto. New Horizons is an unmanned spacecraft on a mission to conduct the first flyby and study of Pluto and to fly by and study one or more other Kuiper Belt objects after performing a flyby of Jupiter in 2007.

The future of our solar system
By analyzing radioactive elements in meteorites, astronomers determined that the solar system formed 4.6 billion years ago from the gravitational collapse of a giant molecular cloud. This cloud collapsed over millions of years to form a rotating disk with the sun at the center. The planets formed from this disk, with the inner rocky planets closer to the sun and the outer gas giants farther away. In around 5 billion years, the Milky Way will collide with the Andromeda galaxy, and the solar system will be about 100,000 light years from the center of the new merged galaxy.

Searching for Intelligent Life on Other Planets is a Goal Worth Pursuing
Abstract
For centuries, humans have tilted back their heads and gazed upon the heavens in wonder. What’s out there and are we alone in this universe? This paper addresses the need for humans worldwide to continue our search for life on other planets, and argues that it is our natural instinct to discover new worlds, much like the early explorers of the 15th Century. The paper covers the leadership role of SETI, as well as the projected funds for such missions. Themes from fields like astrobiology, economics and motivation will be considered and analyzed from a neutral standpoint. This paper will entertain the notion that we may, in fact, be alone in this universe. Aside from the money, the interest and the people advocating for the extra-terrestrial search, this paper will also address the mathematical probability of life existing in our galaxy, using the famed Drake Equation, contemplating the “habitable zone,” and even looking at evidence of life already found. The paper concludes, explaining why the search for intelligent life on other planets and our universe is a worthwhile goal.
