Exploration on Mars For College Students/Adults \Final-Astronomy Objectives Students will understand the following: 1. Since the dawn of the space age in the 1960s‚ we have sent spacecraft to the most easily reached places in our solar system‚ such as Mars. 2. For exploration of celestial bodies‚ NASA has developed a three-phase strategy: reconnaissance‚ surveillance‚ and in-depth study. 3. Each mission to Mars has made specific discoveries and raised questions to be answered

Water and Life on Mars Mars perhaps first caught public interest in the late 1870s‚ when Italian astronomer Giovanni Schiaparelli reported using a telescope to observe canali‚ or channels‚ on Mars. By the turn of the century‚ popular songs told of sending messages between Earth and Mars by means of huge signal mirrors. On a darker side‚ H.G. Wells’ 1898 novel The War of the Worlds portrayed an invasion of Earth by technologically superior Martians desperate for water. (1) In the early 1900s

All planets except Mercury and Venus have at least one moon. Saturn has the greatest number of moons—18. In 1995‚ the Hubble Space Telescope detected what appeared to be four additional moons of Saturn; however‚ that discovery has yet to be confirmed.

Life on Mars For centuries people have speculated about the possibility of life on Mars owing to the planet’s proximity and similarity to Earth. Serious searches for evidence of life began in the 19th century‚ and continue via telescopic investigations and landed missions. While early work focused on phenomenology and bordered on fantasy‚ modern scientific inquiry has emphasized the search for chemical biosignatures of life in the soil and rocks at the planet’s surface‚ and the search for biomarker

Planets of our Solar System The Earth: The earth is the fifth largest planet of the solar system. The life is possible on the earth because its gravity is sufficient to hold atmosphere and best conditions for sustaining life. It contains a large amount of water in the form of oceans. 71% parts of the total area is covered with water and the remaining 29% is covered with land. The temperature of the centre of the earth is 2000° C. The circumference of the earth is 40‚000 km. The earth completes

Life on Mars? For years‚ planet Mars has been in the NASA spotlight. The Red Planet has been explored as images‚ atmoshpere samples and samples of various surface formations have been collected to continue research in labortories here on Earth. The year of 1965 marked the beginiing of the Mars Program‚ and ever since rocket born cameras‚ spacecraft voyages‚ and other advanced technologies have been a part of the explorations. The Mars Program has been dedicated to finding what the planet

Colonization of Mars What does a planet need to have in order to support life? Earth is unique in our solar system because it is the only planet that is supporting life. Some scientists go so far as to say that the Earth is a “perfect planet” because it has features that are the perfect environment for living organisms; these features include our atmosphere‚ water‚ and a single moon. Earth is also in a place in our solar system where the Sun gives off the right amount of energy to drive the

question. Scientists have found many planets which have the potential to support life. However‚ it is the Earth’s neighbor‚ Mars‚ which has the biggest chance that life may exist on. In my opinion‚ I think we still have to go a long road to answer the question: “Is there life on Mars?” Mars is the fourth planet of the Solar System. It is the nearest planet to Earth. Therefore‚ there are many similarities between two planets. For example‚ according to BBC (n.d.)‚ Mars has the surface with mountains‚ valleys

Mars Curiosity and Sky cranes 96% of space is undiscovered‚ NASA has only been able to discover the small 4% of the galaxy that we can see from our atmosphere. There is lots to explore out there in space and in the whole universe. If you are wondering what NASA is doing to expand our knowledge of the galaxy that we live in‚ read on to find out interesting details and information. Engineers at NASA have designed a curiosity rover it is about the size of a small SUV‚ weighs approximately 2‚000 pounds
