Congressional Testimony Says NASA Has No Plan For the Journey To Mars (blastingnews.com)

MarkWhittington writes: Testimony at a hearing before the House Science Committee's Subcommittee on Space suggested that NASA's Journey to Mars lacks a plan to achieve the first human landing on the Red Planet, almost six years after President Obama announced the goal on April 15, 2010. Moreover, two of the three witnesses argued that a more realistic near term goal for the space agency would be a return to the moon. The moon is not only a scientifically interesting and potentially commercially profitable place to go but access to lunar water, which can be refined into rocket fuel, would make the Journey to Mars easier and cheaper.

    I've been saying this since the idea of going to Mars came up in the first place. Let's go back to the moon and figure out how to live there, before travelling an insane distance and strand someone on another planet, and leave them to die.

    Of course there is no plan, because it isn't realistic to have humans living on Mars. The radiation and differences in gravity will see to that. People always say: "oh we will *just* build underground". With what? An excavator you bought at the Home Depot on Mars? It isn't realistic to ever have humans living on Mars. You can't even have people living permanently on the Moon for the same reason. Gravity. Radiation.

      There are no alternatives. We have evolved to live on Earth only. It has the gravity and protection from the radiation we need. Also we cannot "colonize other planets". They are too far away. You are limited by physics from reaching the ones outside of our solar system. And the ones in our Solar System cannot sustain human life. We are stuck here.

      Step one, for any of this, is to build a "permanent" for real ship.

      A Ship that you can point in a direction and go.
      A Ship with a rotating section for artificial gravity.
      A Ship with a multi mega watt power source
      A Ship with several smaller vehicles for going to and from a planet
      etc.

      Shooting people up there in a tin can that will burn up or be turned into a hut just isn't viable. Take the time to do it correctly.

      We haven't evolved to live outside of tropical climates by your argument, because we can't live in Northern latitudes without artificial clothing and shelter.

      Technology is evolution. We now direct our own adaptation to the environment and use technology to live in places that couldn't otherwise sustain us. Living on another planet is no different.

      The things preventing us from reaching other star systems isn't physics. It's economics, psychology, and sociology. Given the money and the will, generation ships are perfectly viable. That's not to say that they are likely, but to say interstellar travel is impossible due to physics is flat out wrong. Hell, use something like Project Orion and you might not even need a generation ship.

    We're pretty sure that - in particularly limited areas - there's water, in some form (ices, hydrated minerals, etc). The problem is not only that you have to set up large-scale offworld mining, melting, filtering, and storage (an engineering project of quite significant note, given the harsh environment and the cost of delivering hardware to the lunar surface), but you also have to create low-cost reusable rockets designed for repeat operation on the moon with little to no maintenance, fueled by materials from the lunar surface. Which is a vastly harder, more expensive task. After all, it makes no financial sense to mine a tonne of water from the surface of the moon and then deliver it into lunar orbit or beyond with 10 tonnes of hardware/propellant sent from Earth, which in turn took 100 tonnes to get off the surface of the Earth. Everything has to be long-term operable entirely in the lunar environment with lunar resources.

    There's not any realistic budgeting scenario where it's even remotely cheaper, all capital costs included, to get your water from the moon in the remotely near future than to just launch it from the earth on existing rockets. But, if your goal is to advance the tech of reusable rockets, space mining, in-situ propellant production, etc, then by all means go ahead. Just don't pretend like you're doing it as a "cost saving measure" for a Mars mission.

    I know many are saying we should go back to the moon first... and we probably will, if anywhere. It makes sense for all the reasons the other posters listed. But, NASA isn't 100% responsible for calling the shots... and as James Cook said, "Never underestimate the incompetence of government."

    Imagine a project at work that will take a year. You've been commissioned to do a study and you present it with the schematics. Good, now go do it.

    Oh, I can only guarantee you that I will give you time to work on it for the next month, and in a month I'll tell you if you have time. I'll need you to develop a complete spec and fixed manpower pricing. But you won't have anyone to work on that, because I need all your people to be working on my other pet project.

    Fast forward 6 months:

    So why haven't you worked on this? Oh, and by the way, your boss is about to retire. His replacement almost certainly doesn't care about this project.

    We'll call you in in 6 more months to yell at you for not being complete.

    Sounds like a good analysis. Personally, I don't give a rip about having people walk around on Mars: I think it's far more important to advance technology of reusable rockets, space mining, etc., so I think going back to the Moon makes far more sense.

    Think about it this way: we landed men on the Moon over 40 years ago. We haven't been back since. What good did it do us, besides having some neat photos and museum exhibits about our past greatness which we cannot replicate now (without a whole lot of money and effort--we can't just launch a Moon mission next month if we wanted to)? We've actually **lost** the capabilities we had back then: back in the early 70s, we had the ability to send men to the Moon, and we did, several times. Today, we simply don't. Going to Mars will be no different: we'll spend a bunch of money on some big-ass rockets and send a handful of people to Mars, they'll walk around, and then we'll have nothing to show for it besides some photos and rock samples, and we won't be able to easily do it again because it'll be too expensive (because we chose the most expensive method possible because we wanted to do it as quickly as possible).

    If we develop technologies more, then trips to other planets and moons will be cheaper. No, a singular trip to Mars will not be cheaper than the slower method of going back to the Moon and developing a lot of tech and capabilities, but **lots** of trips to Mars, to Saturn, to Titan, etc., will be far, far cheaper if we develop the tech now, than just sending singular trips to each of these places.

    So the important question is:
    Do we want to just send some people to walk around on Mars, and then quit all manned space exploration after that?
    Or do we want to be able to send manned missions all over the solar system?

    If your answer is the former, then going straight to Mars is the correct choice. If your answer is the latter, then going to the Moon is.
