Discussions Discussion Space Travel
Katarina E, May 12, 2013

Hello everybody :)
Space was always fascinated me but I don’t agree wholly with idea of space travel. With milions of people which don’t have water or food for surviving I think it’s absured to send commercial flights in space . With money that world spend on racets, satellits I think that half of that money will save hungry people in Africa and all around the world. Of course that we should explore space around us like we was on Moon in 1969th but it’s not necessary to look for life on Mars or on every other planet if we have our beautiful planet Earth. Greetings to all ;)

    I agree with John,
    that's it the true idea, to defend what we have now: The Earth Planet, our home.
    However, I believe that investing in space travel development would pay off just in case our “efforts” (rather scarce, I must say) in saving our planet will not work.
    In my case I'm firmly convinced that every euro/dollar spent in space return to us quadrupled.

    I agree to a certain extent. I believe that we should definitely use that money somewhere closer to home. To feed starving people for example. But also I like the subject of exploring new areas and space has always been a fascinating subject to me. Another thing I thought of was why not focus on our deep oceans? There is a statistic that somewhere around 98% of our ocean isn't explored yet. So why focus on somewhere away form earth when really there is a whole universe of life that we haven't explored.

    I agree that it is important to take care of our planet before seeking to inhabit and take care of other planets, but I see space travel as a very important aspect of human expansion. The rate at which Earth’s population is growing is beyond anything ever before seen. No one can deny that one day, this world will basically be destroyed due to lack of space for people to live. Nature will no exist due to the needs of humans and the atmosphere will become polluted by waste. This is where the importance of space travel comes in. There are trillions of space bodies in the universe and based on mathematical probabilities and locations to suns and stars, there must be more planets out there that are capable of human habitation. There are probably planets out there that actually even have life and humanlike creatures. If we are going to keep populating the world as we are, it is our responsibility to find outlets when Earth becomes too small for us.

Discussions Discussion Is climate change real? Is it mostly human …
Xavier So, Nov. 5, 2012

HI, I’m Xave, a 7th grader from Taiwan. I believe that climate change is real but I don’t its mostly caused by humans. From what I have learned, I think it is mainly caused by the rapid melting of the glaciers that causes change in climate. Then, I think about how big the Earth is and to think that humans only inhabit thirty percent of the Earth, its hard for me to believe that we are capable of causing glaciers to melt faster.

One more reason why I’m not convinced that humans are mostly the cause of climate change is….. after recently learning the Geologic Time Scale in Science class, it showed that time and time again the Earth always has its ways to fix itself. I believe we should still be aware of our carbon footprint but I’m still not convinced that it plays a big role in climate change.

    Hello Xavier So, I would agree with you that the earth has its ways of fixing itself, but I am not convinced that we are not majorly responsible. Even though we take up only thirty percent of the earth remember that an even larger portion is water (roughly seventy percent). There are very few places that are uninhabited and even then those places are small and dwindling. Also the ice caps are the effect of the earth heating, this being a major outcome of climate change. But an interesting case can be made that the earth does do a lot of damage to itself. I stated in an above argument that one major volcanic eruption could potentially leave the earth as damaged as a hundred years of human advancement.

Life in the Universe

The Life in the Universe curriculum is a unique set of resources, for elementary and middle school teachers, designed to bring the excitement of searching for life beyond Earth into the classroom. The SETI Institute, with funding from NSF and NASA, developed these award winning classroom materials with a team of educators, curriculum developers, and scientists. The Life in the Universe curriculum explores many facets of how scientists are trying to answer the questions: Where did life come from? What is its future? Are we alone?
In the Life in the Universe curriculum, students explore conditions that support life on Earth, and the possible existence of life elsewhere. The curriculum draws upon the experience of SETI scientists, whose research encompasses the full spectrum of Astrobiology: astronomy, life sciences, Earth sciences, chemistry, physics, mathematics, engineering, and many other disciplines. The hands-on science activities were tested nationally in a variety of schools representing a broad range of students. Organized around story lines, these activities pose challenges that require students to investigate what is known about life on Earth.

Two Earth-sized planets found orbiting another star

The planets are the smallest ever confirmed orbiting a sun-like star, and their discovery, reported Tuesday, is an important milestone for NASA’s Kepler mission.

http://articles.latimes.com/2011/dec/20/science/la-sci-planets-20111221

Kepler-20e and Kepler-20f, as the two rocky planets are called, are interspersed with three larger, gaseous planets, believed to be similar to our own Neptune, in an alternating pattern that has astronomers somewhat perplexed. All five planets orbit their sun at a closer distance than Mercury orbits ours.

Mission to Drill Ancient Buried Antarctic Lake May Uncover Earth’s Secrets!!!

http://www.reuters.com/article/2011/10/10/us-antarctica-lake-climate-idUSTRE79964Y20111010

An ancient lake hidden deep beneath West Antarctica’s Ice Sheet may reveal vital clues about climate change and future sea level rises, and uncover new forms of life, according to a group of UK engineers and scientist.

    Wow, the chance for discovering prehistoric micro organisms seems likely considering this environment has been entombed under miles of ice for thousands of years. Very interesting project.

The Odds of Intelligent Life in the Universe

A paper published in the journal Astrobiology, by Andrew Watson a scientist from the University of East Anglia, suggests the odds of finding new life on other Earth-like planets are low, given the time it has taken for beings such as humans to evolve combined with the remaining life span of Earth.

Nasa’s Kepler space telescope finds possible ‘new Earth’

A planet outside our solar system which could become a home to humans, Kepler 22b is the right distance from its star to have water, has a suitable temperature and contains the right atmosphere to potentially support life.

I think that we are not alone in the universe, too many events have made me understand this, the mysteries that surround the Earth and ‘universe are dozens and among these there is evidence of UFO sightings in the past and especially in this time, the universe is infinite and it is impossible that we are the only form of life present.

I think that inquiring into the possibility of life on other planets is a good and interesting thing, and I’d like to do it. I believe that life could exist in the Universe far from the Earth, and I don’t exclude the existence of life forms similar to the humans’ one (for me, everything is possible until the Science demonstrates I’m wrong). In my opinion the discovery of life in other planets would be a magnificent achievement of the humanity,so I’d like to study about astronomy and life when I’ll be older

Some scientists say it is impossible that there is life on other planets,others say that there may be a new form of life.I think it’s possible because if there is life on Earth can there be life on other planets …

    Do you know scientists that said that life on other planets is impossible? Can you tell me how said that?
