Recommended: Spending money on space exploration

Living in space has been man’s dream for a very long time, we are slowly getting closer every day, company such as NASA now how a huge budget, over 20million (Table 2 Full yearly NASA spending) and are researching new ways to get to space. With advances such as the mars rover which is currently collecting information on mars, and the first man on the moon in a few decades we might be able to send a man to mars.
Currently NASA are trying to develop a system of growing food in space. The biggest problems is gravity, of course you can’t use soil as it can move and might float out of the pot, but you can use a substance called Fytocell. Fytocell is a new product which acts as a hydroponic; this means it helps the plant grow by providing it with a constant supply of water. The foam provides the plants with a 60/40% ratio of water and air, this means there plant can grow at the optimum ratio and allows the produce to be larger and grow quicker.
Fytocell is a new produce which NASA are thinking of using in space. The product can help astronauts grown their own food and when there is limit...

  • Fast Plant Growth Lab Report

    1928 Words  | 4 Pages

    The “Fast Plant” experiment is an observation of a plants growth over the span of twenty-eight days. The objective is to observe how plants grow and use their resources throughout the span of their life. In our lab we observed the Brassica rapa, a herbaceous plant in the mustard family which has a short cycle which makes it a perfect plant to observe in this experiment. Like other plants the Brassica rapa must use the resources in the environment to create energy to complete itʻs life cycle and reproduce. By observing the plant it is easy to see in what organ or function the plant is using itʻs energy and resources and if overtime the resources switch to other part of the plants. By conducting this experiment we are able to observe where and how plants allocate their resources throughout their life by harvesting plants at different points in their life.

    Obtaining a secure supply of food is one of the most important parts of life. Acquiring food and its preparation is changing with the times, but the age-old art of preparing a healthy diet from natural ingredients is being put to use even today. After harvesting wild vegetables, those which are not eaten right away are dried and stored. It is important to provide an ample supply of food, because the summers are short and the winters are long in Hokkaido. The Ainu have made it a rule not to pick more than necessary, and of what was collected all o...

    With the rapid growth of our global population pouring into the next millennium, we will witness an ever-growing hunger rate around the world. That is unless we call for a revolution on the global scale. The Green Revolution which already sprouted in the early part of the century only need to add a bit more momentum and we will see a bright future for the human race, a future without hunger and starvation ¡V hopefully.It is becoming increasingly difficult for the planet to support its overwhelming population. And since the amount of arable land available is becoming scarce, we must seek ways to dramatically improve crop yields of existing cropland.

  • Communication and Internet Addiction

    In her article “Friends Indeed?” Joel Garreau explains that for two decades, online social networks have been touted as one of the finest flowerings of our new era. But what is the strength of ties so weak as to barely exist? Who will lend you lunch money? Who’s got your back?” Technology has overtaken individuals by social media, allowing many people to communicate online rather than having face-to-face communication. Many “relationships” begin online, and end online. Although, true relationships are rarely created fast, it gradually grows and becomes stronger and stronger over the years. However, in our immediate society this is not the case. But the questions still remains, as Joel Garreau points out “Who would lend you lunch money?” in other words, who will help you physically not online. In our impatient society, technologies influenced the way individual communicate, and that often times leads to depression, loneliness and addictions.

    Not only that, but our population has been growing at an extremely alarming rate. At our current rate, our species may not be able to survive for much longer. This is where space exploration comes in. With the recent discovery of water on Mars, and the finding of Kepler-78b, it is possible that mankind can prolong our existence. The possibility of interstellar travel seems to be an option, or even a necessity, if we wish to continue living.

  • Humans Should Explore Space

    984 Words  | 2 Pages

    The recent events regarding the NASA Mars probes have renewed the debate of reinstalling manned space missions with the objectives of exploring and landing on foreign worlds such as the moon and the red planet Mars, rather than the use of solely robotic craft and machines. It is my belief that we should return to the days of Neil Armstrong and Buzz Aldrin, those of manned lunar landings and manned space exploration. Robots simply cannot and should not be allowed to be the sole means of visiting these worlds, nor should humans only be able to witness new findings second hand through the use of computers and machines. It is human nature to be normally curious of one’s surroundings, and it is important that we send one of our own to new worlds. The effects that past missions have had on the world’s people, as well as our political and cultural climates are another valid reason for flesh instead of metal to lay claim to space. Also, the limitless applications and new education that manned flights can bring to us from on site human interactions could lead to another technological and industrial revolution like the original lunar programs had done for us during the Gemini and Apollo programs.

  • NASA's Journey to Mars

    Humans can expect to face some major challenges on an expedition to Mars. It has been proven that humanity can travel in space for over two years. Cumulatively, Sergei Constantinovich Krikalev, a Russian cosmonaut, has spent over eight-hundred and three days in Earth orbit (Lyndon B. Johnson Space Center, 2005). The expedition to Mars would require the crew to endure a six month journey to the planet, a year of living on the planet, and a six months journey back to Earth. Russian cosmonaut, Valery V. Polyakoz, clocking in at four-hundred and thirty-eight days for just one stay in Earth orbit, shows humanity is capable of a twelve month round trip to Mars (Schwirtz, 2009).

  • Advantages of Space Exploration

    1395 Words  | 3 Pages

    There are many reasons that space exploration should continue. If Earth ever becomes too overpopulated or over polluted, then perhaps people can move to Mars. The world population in 1970 was approximately 4 billion people, and is currently nearly 6 billion people. The world population in 2015 is estimated to be 7 billion people. There is a possibility that there are useful resources on Mars. Scientists have found ice and some other clues, such as craters, volcanoes, and valleys, that have led them to believe that there was once life on Mars, and they believe that sometime in the future, should planet Earth need to be evacuated, humans will be able to live there (Jakosky 142). Many of the rocks on Mars appear to have been formed by gasses, breathable by humans and other creatures. A process called terraforming will allow astronauts to make use of the resources that are on the planet and create an atmosphere that will support life. One method for terraforming is that scientists would convert the gaseous rocks back into gasses, and use gas-eating organisms to eat the gas, which results in the formation of other gasses. If these organisms continue the cycle, then Mars would have a stable atmosphere for humans to live in (Getz 39).

  • The Future of Space Travel

    920 Words  | 2 Pages

    An Astronomy topic that has always been intriguing is space travel. The ability to rocket into space, look down on Earth, and “…explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before” (IMDB) is an adventure that people dream of experiencing. On July 20, 1969, an estimated six million people watched Neil Armstrong become the first man to walk on the Moon (Nixon Library). Presently, people are paying Virgin Galactic $250,000 to reserve a seat on a spaceship that is expected to tour suborbital space in the near future (Virgin Galactic). Although space travel continues to be of interest, there is also some controversy. Controversies include: the allocation of government resources for space exploration, government verses commercial spacecrafts, and the need to colonize other planets for the survival of humanity. The intrigue and the controversy of space travel are the reasons for this Astronomy conversation.
