Discussions Discussion Space Travel
Cheyenne S-US, Feb. 28, 2014

Space travel is a great invention. There is so much to learn and explore outside of this world. With space travel we can look for life on other planets (plants or animals) and maybe bring life to other planets. Space travel is a life long dream for some people and they would be very excited to go up into space and explore all of the possibilities. Also, space travel will add to advancements in technology due to constant studying. We could send space robots out into space to explore places we cannot get to or send them up there without a person even going.

Going to space is something many people have always dreamed of doing. Not only do people see it as a life-changing experience but it also opens new doors to technology and shows us what is actually happening in our Earth. There is always a possibility for new discoveries and going to Space definitely increases the discovery rate. We continue to find new things every day and hopefully we will even have new life here on Earth!

Space travel is really interesting thing. When I was young, I wanted to become an astronout. Now I still think that travel in space can be really exciting. For example, you are able to see your planet Earth from the space. In my opinion it is really cool:)

Discussions Discussion Should NASA be worried about the events that …
Jim D., Oct. 6, 2013

Sometimes a movie brings alive real life events, but those events could actually happen and sometimes it couldn’t. I was reading an article about how NASA feared that the events in the movie ‘Gravity’ could actually happen. But before I go into the article, I would like to discuss events that happen in “true story” movies. Could those events really happen? If they happen, Is there a way to prevent it? Should Hollywood stop producing movies that portray real life events? The article below shows NASA’s perspective on the movie ‘Gravity. In the movie ‘Gravity’ by Alfonso Cauron, Sandra Bullock plays an astronaut whose goal is to repair an instrument as soon as possible, but her plans are ruined by a series of terrifying events that have crossed the minds of astronauts and space junkies. Below are some of the trials that Bullock’s characters faces (spoiler alert) and their chances of actually happening, according to NASA experts:

The evidence below states the challenges:

Russia blew up its own satellite and created a tsunami of space junk.”

I got disconnected from my ship.”

We can’t get home.”

The space station is on fire.”

The first challenge is possible, but space junk can only pose as a threat if it is flying lower than 400-kilometers. NASA does track down the space junk in this zone, and the station’s thruster can change it’s orbit slightly to avoid crashing. The second challenge is extremely unlikely because an astronaut’s chance of getting disconnected from the ship is very small. If they get disconnected, astronauts space walk in pairs and wear thruster belts. No space walkers or their steel tethers have ever been struck by debris. If by any chance, an astronaut does get hit by debris they must get back to the vehicle as soon as possible. The third challenge is extremely because NASA requires all missions to have an escape capsule. The ISS have two Russian Soyuz capsules and NASA always has an escape capsule. The fourth challenge is possible because as Uhran says, “Fire is one of the greatest hazards that can occur on the space station.” In 1997 an oxygen canister ignited the Russian station Mir, which resulted in smoke and meter high flames. Cosmonaut Valery Korzun managed to drench the flames. If he failed, half the crew could have died because the fire blocked the way to one of the two Soyuz escape capsules. But Uhran says that materials on the space station have high ignition temperatures so that small fires won’t spread. I believe that NASA does have a right to be afraid of those events of happening in real life. Even those these just happened in a movie, there is a possibility that these could’ve actually happened.

Human space flight is a very honorable thing for human history, because of all the human developments from millions years ago until today. I think it is a great thing to explore the universe, because we need to keep explore that way we can improve our technology better. However, human should also learn from the exploration in the universe, that how valuable is one Earth, people should protect them and keep this planet as long as possible, instead of destroy it.

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.
  • Nick Cerdan Nick Cerdan Oct. 19, 2013
    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.
  • Mary M Mary M Feb. 24, 2014
    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.

Hello everybody. I am Eric from the USA and personally I think that the universe is very interesting. The advancements that we have been able to achieve in the past 20 years is nothing short of outstanding. The rover that was sent to Mars is a huge accomplishment for the US as well as the rest of the world because it means that we are beginning to understand life beyond planet earth. Who knows, maybe one of these experiments may lead to the discovery of something extraordinary, like extra-terrestrial life.

    Maybe you're right, but we can't know (if it's real) what the extra-terreste will be able to do. And there is no oxygen on Mars, i don't want to leave with a space equipment all of my life.
  • Lucas Scheidler Lucas Scheidler Feb. 8, 2013
    I'm agree with Morgan Schepens but there is oxygen on Mars but not enough to breath !
  • Sage Borlo Sage Borlo Feb. 12, 2013
    There is evidence that there was once possibly a sustainable ecosystem on mars, but that's far past, and Mars is a rather dangerous place to settle now. A more likely subject in our specific solar system would be Titan, one of the many moons of Saturn. It holds the best conditions in our solar system for colonization.

Hi! I’m Mandy Chan from Taipei, Taiwan. I was watching the news on Curiosity on Mars, and our solar system has always fascinated me. The improvement of human technology allows us to send robot or cosmonaut to the empty space. The first human spaceflight was directed by the Soviet Union on April 12, 1961. This was a new milestone for human beings. Nowadays, space travel becomes very popular because of danger caused by global warming. Different countries began to compete with each other by sending astronauts into space. They felt the threat of the nature slowly destroying our planet, and hoping to find a new world. So you can say that space travel gives people hope, strength and faith. On this deteriorating Earth, people eagerly wanting to find a place that human generation can survive. Knowing that our planet is dying, exploring the unknown space gives us a chance. So space travel is a good influence to this rotten society.

China’s next space mission to be manned, will attempt to dock with space station module:

The Shenzhou 9 spacecraft will be launched aboard its Long March 2F rocket sometime between June and August. The astronauts will manually dock with the Tiangong 1 module that was launched last year and conduct scientific experiments while aboard, Xinhua said. It didn’t say how long the mission was supposed to last.

China completed its first such space rendezvous last year when the unmanned Shenzhou 8 docked with the Tiangong 1 by remote control. That was considered something of a breakthrough since early U.S. astronauts did so manually.
