More from astrophysicist Neil deGrasse Tyson

If you're looking for more from astrophysicist Neil deGrasse Tyson, who was on GPS today, you can check out his Foreign Affairs article here (behind a pay wall) and/or order his book here.

Here's an excerpt of from his Foreign Affairs article:

In 2010, U.S. President Barack Obama articulated his vision for thefuture of American space exploration, which included an eventual manned mission to Mars. Such an endeavor would surely cost hundreds of billions of dollars - maybe even $1 trillion. Whatever the amount, it would be an expensive undertaking.

In the past, only three motivations have led societies to spend that kind of capital on ambitious, speculative projects: the celebration of a divine or royal power, the search for profit, and war. Examples of praising power at great expense include the pyramids in Egypt, the vast terra-cotta army buried along with the first emperor of China, and the Taj Mahal in India.

Seeking riches in the New World, the monarchs of Iberia funded the great voyages of Christopher Columbus and Ferdinand Magellan. And military incentives spurred the building of the Great Wall of China, which helped keep the Mongols at bay, and the Manhattan Project, whose scientists conceived, designed, and built the first atomic bomb.

      Yes, Fareed, space technology has future. How about the depth of our oceans? It's also an interesting field!

    It used to be that some opposing soldiers in the midst of battle would call a truce on Cristmas day and even have a friendly game of soccer. Not that it has to do anything with Christmas (God forbid I should leave out someones deity) but how about calling a global truce for a year or two and putting all the money and effort to getting us off this planet.

    Good show,...Thanks

    We learn a lot from NASA and our space program...Just look at Algae,,We will need to take oil with us into space..so we will take algae because we can make anything we make from black oil from algae...now if we just built algae ponds in out vast deserts..we could grow our oil...

    We could sent robots to Mars, or the moon, to build the first bases or setup mining operations for a fraction of the cost of a manned mission, and we would not need to support those robots with continuous costly supply shipments...and we could then send the people after the base is completed and sustainable for humans...

    I liked the technology cross over pointed out in your show..that is very true.does happen all the time..I once analyzed satellite, and video data to identify targets for DOD...lock onto those targets for weapons tracking..and when I left the DOD I tried to do the same with X-rays and CT scans for identifying bone fractures, tumors, blood clots...and I also was looking at taking high definition digital photos of x-rays to be transmitted to radiologists hundreds of miles away...all those attempts failed not because the technology was not there, but the laws and medical sub-structures were not there to support that kind of work by a small business...

    This guy was impressive! I work in science research in an admin capacity but his explanations of translational research across fields, was especially convincing. I think if this majority of people understood this "connection" there would be so much more support for NASA and our space program(s). I hope he is able to speak on this topic in many other venues. I had no idea the extent to which we were abandoning our space endeavor nor would I especially have cared had I not heard Dr Tyson.

    I I love your show. But, today, I would have not had Charles Murray on the show. His thinking is out in never-never land. Then used the time to give the religion panel. That was a good and interesting conversation.

      I agree with Les, Charles Murray and The AEI is so clueless. The guy needs to come up to speed with the changes in society. He is stuck in the 50's. The upper middle class work so hard because they are forced to do so. You think they want to? Come up for air dude

    I missed most of the show (will catch it on iTunes later) but I did see the Charles Murray segment and I sincerely hope you will talk with a learned person, sometime soon, about countries where marriage isn't thought to be so important – or desired – and where children grow up to be valuable, contributing members of society all the time. Think Sweden.

    Of course that would likely require acknowledging that a communitarian society is the "cultural" structure that makes it happen.

    My husband and I thoroughly enjoy your shows. We really appreciate your global perspective; your information has broadened our perspectives on numerous topics. We especially enjoyed today's panel where there was no arguing–just intelligent discussion. Please keep it that way. We have quit watching Meet The Press because it is so divisive and cantankerous. Keep up your great work!

    I watch your show every Sunday and feel that it is the best that CNN has to offer. Usually objective and intelligent information, even though it is almost completely dominated by the male thinking model. At least it includes women and attempts to represent their viewpoints in an honest way.

    However, today giving time to Charles Murray and his new book was outrageous and has angered me. I am not a single mother however I feel it is necessary to speak for them. Most woman are caring toward their children and understand that they need to support their children. It is sad that many men are not willing to take on this responsibility for a variety of reasons. however to let Mr. Murray say in a judgmental way that there is no room to discuss this problem in society and that is why he wrote his book, is unbelievably patronizing to women who are doing their best to care for their children. If he was on the side of these women he would be stating that he wants to support the single mothers of America and here is how he proposes he and his followers do this. What are his action steps?

    I believe that the American culture will reinvent itself in order to support the growth of it's children. Let's consider a culture that needs to support single parent families, or extended families or community families who raise the children. He is traditional in his approach to the question and doesn't have the courage to hold men responsible for not doing their traditional part. Fareed, why didn't you speak up and hold his feet to the fire.

    There is a new world coming and women understand that it is based on female values of nurturing, caring, honesty, good food, water, and education whether these values are found in a two parent family or some other family form. I always believed you understood the "Yin" as well as the "Yang". However, after letting Charles use you and your show to promote his divisive values, I am not so sure.

    This is just like people telling women that they don't have the write to use contraceptives freely and to have abortions. Charles Murray's statements are his way of saying what he thinks is clever, supporting it with data from the past, creating more division in our society and making a lot of money while doing it.

    Week after week Fareed Zacharia GPS offers the most informative commentary of any program available.
    The level of discourse provides perspectives that enlighten thinking. The guests do not "talk-over" each other and
    and personal narcissism is not apparent.

    Mr. Tyson appears to making a case to prevent substantial defunding of NASA. Its always seemed to be a government jobs program to many.

    If many of its contractor have dreams, by all means, lets not stop them: No government contracts.

    The Defense Department has similar problems–though many Americans despise the idea of full time wars.

    The likes of Rutan, Allen, Bezos, and Branson seem to be functioning well without government aid in their space bound goals.

    At the conclusion of today's show Fareed gave Jon Meacham's "Franklin and Winston" a plug.This book earned Meacham a Pulitzer. However it would be nice to get his response to the question "At some point in your research for this book did you have to ask yourself "Am I an investigative journalist or a producer of 'feel good historical romance'? I would claim you must have opted for the latter but was this a conscious decision? Thankyou.

    1905-Einstein’s "miracle" year: Special/General relativity: Black holes exist; E=mcsq velocity created by a black hole can disintegrate mass completely; Brownian motion: we are undergoing kinetic velocity; Photoelectric effect: We can create from a black hole. Special recognition to Albert Einstien.

      Yes, the world seems to agree that Einstein was a very intelligent and respectable individual. He also had many quotes and advisements which the world unfortunately does not want to heed.

    Solydra story is opening a huge can of worms at the DOE LOAN GURANTEE LOAN PROGRAM. Its not just about the Solar loan guarantee program. Look at all the millions in fees collected by the DOE LOAN GUARANTEE PROGRAM with algae projects less than 20% completed. An audit needs to be done on all DOE Biomass Program Grants to algae researchers.

    The US taxpayer has spent over $2.5 billion dollars over the last 50 years on algae research. To date, nothing has been commercialized by any algae researcher.

    The REAL question is: Does the DOE BIOMASS PROGRAM really want the US off of foreign oil or do they want to continue funding more grants for algae research to keep algae researchers employed at universities for another 50 years?

    In business, you are not given 50 years to research anything. The problem is in the Congressional Mandate that says the DOE can only use taxpayer monies on algae research, NOT algae production in the US. So far, algae research has not got the US off of foreign oil for the last 50 years!

    ARPA-E halts algae project, citing missed milestones
    Jim Lane | February 16, 2012
    Share"In Washington, the DOE has halted a research project at Iowa State University funded by ARPA-E to develop biofuel feedstock from an aquatic micro-organism for failing to reach research milestones. About 56% of the $4.4 million grant was used. Politicians against increasing APRA-E funding as proposed by President Obama’s new budget are using it and other halted ARPA-E projects as examples to reject the program."
