from the regolith-monolith dept.

On July 1, Johann-Dietrich Wörner will become the new general director of the European Space Agency. SPIEGEL speaks with him about his dream of building a colony on the moon and the difficulties of traveling to Mars.

SPIEGEL: Which celestial body would you like to travel to most of all?

Wörner: My dream would be to fly to the moon and build permanent structures, using the raw materials available there. For instance, regolith, or moon dust, could be used to make a form of concrete. Using 3-D printers, we could build all kinds of things with that moon concrete -- houses, streets and observatories, for example.

SPIEGEL: The only question is how you intend to transport European astronauts into space in the future. Currently, you are completely dependent on Russian Soyuz capsules. If relations with Russia continue to worsen, it could jeopardize joint flights.

Wörner: Russia is and remains an extremely reliable partner for us. Even in the Cold War, space travel helped ease political tensions. Just think of the famous rendezvous maneuver in the summer of 1975, when an American Apollo spaceship and a Soviet Soyuz spaceship docked while orbiting the earth. And today, we space travellers can once again help overcome the current period of crisis.

[...] SPIEGEL: Shouldn't we Europeans be capable of taking people into space without outside help?

Wörner: Unfortunately, we missed a number of opportunities. For instance, it would have been possible to convert the ATV cargo spacecraft into a manned spaceship. We should have done more with that.

SPIEGEL: What caused the project to fail?

Wörner: Money, as is so often the case in life. Every nation wants to shoot astronauts into space and toot its own horn for doing so. However, there is only limited enthusiasm among the ESA member states to pay for manned space travel. But perhaps there will be new opportunities at some point. I'm not giving up hope that we Europeans will create our own manned access to orbit.

Can we make it to the stars without national prestige being the goal?

    In before comments close :D (feel free to reply elsewhere if you want to or send a mail, I'm just very late in catching up is all).

    I find the idea of hollow moons and planets very likable/entertaining/appealing but you might want to read this [] and apply a hefty amount of salt¹ to the page you linked. It's still a lovely idea though and who knows maybe somewhere in the vast future our inheritors might discover such a hollow object somewhere :)

    Unfortunately there's a lot more stuff that shoots holes into that page you linked:

    1. For the existence of any life of the kind that exists on Earth tides are believed []² to be crucial, although the supposed link between lunar months [] and mammalian menstrual cycles seems weak, nonsensical, or simply nonexistent []
    2. The complete lack of any NASA pictures or (search engine readable) texts using the naming convention provided (at least in my search), i.e. not even any partial matches to NASA sources (and in my opinion there should be loads if it was genuine, not of the same picture or feature but at least from the same source).
    3. How trivial it is to add elongated black shadows to a picture or to misrepresent (or create or exacerbate) transmission and/or imaging artifacts in extremely low resolution photographs (judging the unimpressive results I did find on non-NASA speculative pages).
    4. NASA's Project Moon Blink []³ and the NASA PDF [] (4.1 MB).
    5. A lot of the claims on the page you linked are simply wrong/outdated, or even “not even wrong” (like the whole volcano thing or not realizing that moonquakes are fueled and triggered by tidal forces from the Earth acting on the Moon). There are magnetic fields [] on the Moon for instance but it should also be obvious from the surface that a lot of material has arrived from elsewhere, some of which might have been magnetic or become magnetized on impact —plasmas for the win! :D

    Sorry if this is a very dull reply, I'm not against “weird stuff” I only want it to be some of the real weird stuff (like the Moon Blink thing or sprites [] or ball lightning [] or Hessdalen lights [], not that serious [] “forteana” [] or unusual history [] can't be fun too although I never really have the time to indulge in it any more), there is enough of that to go around in both science and in life in general :3

    I actually cried when Hynek [] died :(

    Damn the world has changed an incredible amount in thirty years (and obviously I'm older than that) …and by mentioning that I now feel like a dinosaur …although maybe I kind of look like one too XD *struggles not to get sucked into the massive vortex of nostalgia*

    However if it was my choice the Moon would be a as hollow as a Kinder Egg except for all the spaceship parts (“aliens”/“gods”/ancestors optional) and internal rotating artificial/simulated centripetal gravity XD (no need for any “magic gravity carpets” —I'm not keen on that kind of hand-waving).

    ¹ Funnily enough that idiomatic expression is based on superstition i.e. a superstitious interpretation (cleansing) of the preservative quality of salt.
    ² I write “believed” because while it's convincing it's still speculative.
    ³ Not “Operation” but “Project”, perhaps a trivial difference for something published in 1995, not as easy to find out then I guess (why didn't the writer contact NASA?).

    By the way a bit more on moonquakes []. Not all kinds are tidal and maybe the sun is a larger source of tidal stresses (I don't know).

    Some other links that might interest: lunar dome/shield volcano [] and Transient Lunar Phenomenon (TLP) [].
