    Didn’t know where to put this:

    I have gotten emails from this site called “LiveScience” for awhile now, probably because I am signed up for news from Space.com

    This week I opened the email and see the above article in the middle of several other science pieces. I don’t remember seeing something quite this blatant before, taking a topic like this and shoehorning it into a so-called science blog in order to get a political point across to the readers…… :-(

    Needless to say, I looked for a way to unsubscribe, finding none I just marked it as Spam. Unbelievable.

    Steve–
    Skimmed that article your referenced, and it is unbelievable!

    Concerning the Gateway to nowhere, I think that the ISS was the last governmental HSF project that will ever be accomplished (except for China). Launching people on SLS/Orion will be too dangerous when there are well proven and much cheaper private launch alternatives. I think it will be politically impossible to spend $150,000,000,000 tax monies on another space station when there are much cheaper, much better private alternatives in operation much sooner. As an analogue, NASA used MIR in the 1990s because it was available. Catastrophic political mistakes like the horrible design flaw of putting a space station in cis-Lunar space will be avoided in the future.

    I don’t know about that. United Launch Alliance seems to think that cis-Lunar space stations could be a good idea, so horrible design flaw or not, in a few years they may give it a try, such as at the Earth-Moon L1 location.

    An EML1-station makes sense for exploring the Moon’s surface. A place to shift between the Earth=>station transfer spacecraft (voluminous for a 2-3 day trip) to the station=>Moon lander (minimal but with ascent/abort capacity). That would be a station that is crewed only temporarily on the way to and from the Moon’s surface. The Lunar surface base would have abort option to the station instead of all the way to Earth. And the station would have abort option quickly down to the surface base.

    The Gateway to nowhere skips the Lunar surface entirely, and as a substitute for the ISS it is a downgrade that only will be crewed temporarily because of the radiation issue and the lack of immediate abort to Earth options. They have to add 3½ km/s delta-v to get from LEO to EML1. For Falcon 9 that means about 9 tons instead of 22 tons delivered. They need a launcher as large as Falcon Heavy in order to launch ISS sized 20 ton modules to EML1.

    Lunar exploration should start with an intensive robotic campaign followed by a few shorter crewed missions, and then a Lunar surface base in the best site identified. An EML1 station would be a filial to the surface base. It’s not the thing to start with.

    Yes, they do have a wide reach, all the more reason this jumps out. I guess I have become used to seeing countless articles about AGW all screaming “SCIENCE!” to the point that my eyes just glaze over (and the louder the author screams “SCIENCE!”, the less likely there is any true science in the article…. LOL)

    This one really caught my attention though. It doesn’t scream “SCIENCE!”, it screams “Trump Derangement Syndrome!”

    And I know that it’s all around us now, I have several friends that are just crazy lately, but how the heck did this pass the smell test at any legitimate Science reporting site? Are they so deep into TDS that no-one there said “Hey, this is a Science Blog, not a Political Blog”

    And there is no comment section, isn’t that convenient? LOL

    LocalFluff,

    I see your point, now. NASA’s idea for a cis-lunar station is similar to the SLS project: it is an expensive something to have, and it lacks a mission. That is a horrible idea.
