  • It is not obsolete, but man can't stay in space long enough; so it is pointless.

    It is not that they are obsolete, they are just too expensive; and, man has made about all the strides in space technology that can be made until new propulsion systems are developed where rockets don’t need thousands of tons of fuel. Without much more powerful rockets, we will never be able to lift enough weight to bring everything needed for a manned trip to Mars. It is doubtful that we could build a an outpost on the moon and keep it resupplied.

    People think we have made great strides because we have had success getting to the space station and returning to earth. What is forgotten is that the journey to the space stations is a 200-250 mile trip, which is the approximate distance between New York and Boston. The Shuttle also flew to the Hubble Telescope, which is about 350 miles, less than the distance from NYC to Norfolk, VA. The distance to the moon is 238,000 miles and the closest known approach to Mars is 34,800,000 miles or 34.8 million miles.

    Most people don’t realize that the space station needs to be resupplied with food, parts, and emergency water via the shuttle at least once a year, or more frequently if an emergency happens. There will be no feasible way to resupply a space ship to Mars with parts to fix any of the necessary systems that generate air and water, and scrub the air. If the backup systems fail, it is over.

    And, people who say stupid things like we will have to use space ships to send millions of people to live on Mars or other planets because the earth is overpopulated and running out of space are living in the fantasy world called la la land; these people are total idiots.


  • Yes, it seems they've become so.

    It's been so long since I've heard of a manned space flight, that yes, it seems that they've become obsolete. With the advancement of technology in general and also space technology, there doesn't seem to be the need there once was to have an actual man in flight. Technology can do the monitoring, and that's probably safer, also.

  • Far from obsolete, they're our main hope for the future.

    There's a famous quote from an early Russian rocket pioneer : "Earth is the cradle of Humanity - but we cannot live in the cradle forever." In the long run, Humanity needs to move to other worlds and even other star systems if it is to grow, learn, flourish and survive. Robot explorers are great and complement this end but they are not a replacement for people actually going there. It is in our nature to want to see and settle over the hill, beyond the mountains, across the seas and eventually off the Earth. To end with another paraphrased quote (from Babylon 5) if Earth goes and one day it will, it will take with it all Shakespeare, Marilyn Monroe, Leonardo da Vinci, all Humanity's greatest accomplishments and works and those are worth fighting to preserve and share. Human Space travel and colonisation is our last best hope for the future and an essential way of keeping all Humanity's "egg's" out of the one vulnerable basket.

  • We cannot define our scientific limitations through limited science.

    Nearly every major scientific event was considered by some to be unlikely. There was time when many people thought that televisions were a fad or that submarines had no purpose beyond drowning their occupants. Napoleon Bonaparte himself thought that it would never be possible for a ship to sail against the winds and currents by "lighting a bonfire under her decks" and that any plans for steamships were nonsense. If History has taught me much, it is that our limitations are defined not by science but rather by our own self doubt and that compound interest is a force that only God Himself can contain.
    My position is not that day trips to Mars will become a common thing in the near future but rather that if people were willing to spend weeks at sea to reach the Americas, it is not unreasonable to expect many to be willing to go to Mars.
    I do not expect it will start with cruises. Nor do I believe that starting life on the moon or Mars would be easy. There may be Roanokes. There may be another Apollo 1 and I expect that as traffic increases, there will be another Challenger. If humans are as they have been since Eve bit the apple, we will move forwards. Great achievement does not come by achieving a point and reaching the limit, it does not come to those who succeed for successes sake or for those who stay within the known boundaries, it rewards the courageous and follows those who choose to ignore the limits and go beyond what is safe. History does not remember those who are society or merely contribute to it but rather those who create societies and move societies. In a would where we have roadways that go under mountains and rivers. Where crossing the English channel without touching water is common, where we can make what were once considered impossible trips from Boston to Kigali in hours and can cook oatmeal in a minute. We are in a world where knowledge can travel faster than bullets and where small pox has been wiped from existence. The dangers of space are real but so is human bravery and human bravery, like science, has no limitations

  • We all need a little adventure.

    Rovers, and other mechanical space technologies do not have the ability to explore and find life on other planets like the ability a human being has to do it. Eventually do to population growth people will have to be sent to other living places other than earth to survive. Finding new ways to send human life to space in essential to the future of human livings.
