Hey, dummies, this will most definitely not be "the longest, most hazardous voyage in history". Three years is a long time, but explorers have often set out on voyages that take longer. Have you maybe heard of Charles Darwin and The Beagle? That voyage took almost five years, and it still isn't a record. And it's straight up laughable to say that it's the most hazardous voyage in history. NASA will never run it if the chance of death is over 10%. By historical standards, I'd call that a voyage of moderate hazard.
And then there's this:
...[T]he first people to go to Mars will be isolated as no human beings have been before. For a long period, 20 minutes must pass for messages to go to and from Earth.
Let's grant that the crew will set the record for being really far from other people, but as the article observed, that's not sufficient for them to be "isolated". Can they then seriously suggest that a 20 minute video communication delay is some unprecedented record of human isolation? Do they not realize that humans didn't always have smartphones?
They don't need to add all this hyperbolic shit to their article. Then again, maybe they do, because it doesn't really say anything specific and non-obvious except that Johns Hopkins got money to study this, and that their test group will consist of surgeons.
If you think the system is working, ask someone who's waiting for a prompt.
