back to article Astronauts on long-haul space flights risk getting 'space brains'

Astronauts flying to Mars are in danger of long-term brain damage and dementia from the onslaught of radiation in galactic cosmic rays, according to a new study. The paper, published today in Nature's Scientific Reports, raises alarm for NASA’s future plans in long-term space travel. Researchers from the University of …

    More reason to boot Donald Trump into space

    If elected, will it be the Donald or the rocket that gets the title "Hair Force One"?

      Get Real..

      Trump is an easy read. He is very thin skinned and he talks in hyperboles. So you learn to take what he says with a grain of salt and don't take him literally.

      Clinton? She is a complete work of trash.

      Setting up her private server as a matter of convenience? Really?

      How many out here have and set up their own email server? And are still running it?

      Brother it ain't convenient. Getting a hotmail or a gmail account is much easier.

      As more documents from the fbi investigation and the leaks from ASSange, we learn that not only the fix was in, but that the Clinton campaign attempted to rig the RNC and the press to push the Republicans to the right. The press were in collusion (well some of them) to get trump the nod...

      But unfortunately we can't change that. We have to choose between Trump/Pence and Clinton/Kaine and it's an easy choice. Trump is the least harmful of the two and Pense seems to be the most Presidential of the four.

      Clinton is a criminal. You can't spin the email scandal that is still unfolding and the only reason she isn't on trial is thanks to Obama and Biden not running. Had Biden ran... Hillary would have been indicted.

      But I digress... Trump in space? Sorry but the Muppets beat you too it.

      See Pigs in Spaaaace!!!

        I have set up several email servers and still use them. This is a techie site, so I am sure many of the commentards here have done done likewise. Reading the friendly manual and following the instructions is so simple that even a Republican could do it. It is so convenient to be able to send emails from inside my own software without having to curl my way through some web interface that changes with the phase of the moon. Imagine you work in an environment where clueless colleagues could send you unencrypted classified documents. Gmail and Hotmail simply would not be an option.

        Please go and work for Trump - and not get paid. While your at it, do some quick web searches for Trump hotel in Russia, Paul Manafort, Trump illegal deals with Cuba, Pam Bondi, the Trump foundation bribing Attorney Generals and Trump University.

          Re: Get Real..

          LOL... little boy.

          Cookbooking a mail server isn't the smartest thing to do and since you mentioned it... Her IT guy, with little experience put an unsecured Windows NT Exchange server on the net. While it was up and running... security was an issue. Even El Reg posted some articles on it.

          As to Trump... he never broke any laws or violated the US's National Security. When you have 100's of former military officers and DoD employees who say that they would be in jail for what Clinton did... you have to start to think that the FBI investigation was fixed. Oh wait. More emails being released from the State Dept along with the FBI notes do point to this... What's the stuff Assange has? We'll just have to see.

          Trump may be a lot of things... but to be sure... he's less harmful to the US than Clinton.

          As to Trump's deals... yeah... I can look at old articles in the Chicago Tribune about the clawbacks he did on the 'friends and families' contracts... Oh yeah... he's no Saint. However he's no criminal like Hillary. ... Note: We haven't even talked about her illegal arms deal in Libya... Do you really want to continue?

        Hilary Clinton goes to a gifted-student primary school in New York to talk about the world. After her talk she offers question time.

        One little boy puts up his hand. Hillary asks him what his name is. "Kenneth," he says And what is your question, Kenneth?" she asks.

        I have three questions," he says.

        "1st -- whatever happened in Benghazi?

        2nd -- why would you run for president if you are not capable of handling two e-mail accounts?

        And, 3rd -- whatever happened to the missing six-billion-dollars while you were Secretary of State?"

        Just then the bell rings for recess. Hillary informs the kiddies that they will continue after recess.

        When they resume Hillary says, "Okay, where were we? Oh, that's right, question time. Who has a question?"

        A different boy -- little Johnny -- puts his hand up.

        Hillary points to him and asks him what his name is. "Johnny," he says.

        "And what is your question, Johnny?" she asks.

        "I have five questions," he says.

        "1st -- whatever happened in Benghazi?

        2nd -- why would you run for president if you are not capable of handling two e-mail accounts?

        3rd -- whatever happened to the missing six-billion dollars while you were Secretary of State?

        4th -- why did the recess bell go off 20 minutes early?"

        And 5th -- where's Kenneth?

        Maybe you've already taken a journey in space. Since when has it been a crime to run your own mail server? Of course running a server is a sane hing to do. It's easy as well. I've been running a mail server for years. Much better than letting Google or Microsoft or Facebook pore over your emails.

        I'm sure Mrs Clinton wan't sure about the security of emails that run through government servers either. I imagine there are a kinds of miscreants - and with high-level clearance - that would be only too willing to take a look at all her email correspondence.

While that would save on weight and volume (and food and drink, with again weight and volume savings) how are they going to explore and mine the resources of all those alien worlds they'll be visiting?

      Fear extinction is what you actually want, so that you aren't staying afraid the whole trip to Mars and back. You want that even more for a presidential term for the Orange Turnip, and let's not contemplate having to be on a trip to Mars with him.

    Maybe the smart first step is to colonize the moon

    Makes civilization significantly more fault-tolerant. Allows us to develop new resources on the moon. Allows us time to work on the medical science necessary to sustain humans in a space environment we are not designed for. Allows us to build (hopefully) a launch complex on the much lower-gravity/no atmospheric-drag moon environment so that we can build larger and better-shielded interplanetary vehicles. And it gives us time to develop better propulsion technologies.

    Maybe Mars is just a bridge too far right now.

      Re: Maybe the smart first step is to colonize the moon

      Why build on the surface? Getting things down into the (pretty deep) gravity well of the moon is quite a challenge in itself. Better to build stuff in orbit. Which is also not as simple as you'd think. The ISS is an achievement in its own right just for the fact humanity has figured out a way to put something that large in space one bit at a time.

      For illustration Delta-V to LEO is 9400 m/s. Delta-V to the moons surface from LEO is an additional 5670 m/s, Delta-V to the martian surface is 6300 m/s from LEO, compared to getting into orbit in the first place, the difference between going to the moon and going to mars is not that big, but if you are building something big, there is a BIG difference in building it in orbit and building it on the surface in terms of energy required to deliver building materials.

        Actually, the real 'first' smart step has already been taken - LEO.

        Robert Heinlein was asked about this once by a journalist interested in why he used space stations in his stories. After the explanation about Delta V and getting off the surface, the journalist said 'Ah. I see now. Once you're in Low earth orbit, you're halfway to the moon.'

        'No,' replied Heinlein, 'Once you're in LEO you're halfway to ANYWHERE'
