    I was disheartened to read today of more gimmicky light polluting junk being launched into space this time by New Zealand. If we recall a Moscow university launched a crowd funded satellite last year which was expected to be the brightest object in the sky after the sun and moon but thankfully it failed to inflate. The Russians claimed it was to test breaking,as in slowing down not breaking up!,in space but it really seemed to be a vanity project ,a vanity project of -9 magnitude had it worked!the New Zealand one doesn't even have a flimsy scientific excuse it's a work of art to show the fragility of the earth but clearly not that of the night sky!although I am impressed that the new Zealanders did manage to construct a rocket using 3d printers and get it up into space ,well low orbit.the satellite is likened to a disco ball and we can only hope it to breaks up or doesn't deploy correctly.

    Don't tell ESA about 3D printing they'll be xeroxing Ariane Fives!

    We can hope it doesn't deploy like the Russian one?I'm a bit sceptical as to if you can 3d print a whole rocket due to all the high stress/pressure parts.bit like the media claims about 3d guns,you could 3d print a gun but it'd blow up upon firing it!

    Perhaps we can send the 3D gun up to the polydecahedron-thing and shoot it down? :p

    Sorry - couldn't resist! :D

    Or 3d print a surface to missile missile and get it on the way up?3d printing is all well and good but 3d printing the components that take the stress?in rockets stuff like the combustion chamber, not possible. In guns breeches, barrels,firing pins,etc..a 3d rocket man still needs a host of original parts.plus 3d printing fuel!

    Why not just print the entire rocket and post it into space? No, come to think of it, the Royal Mail would still lose it.

    Pity one can't 3D-print a few kilo's of Pu239...

    I know where to send it to.

    I'd be worried - if you could 3D-Print Plutonium! :p :cool:

    Hiya Again -

    I was just thumbing/clicking my way through some articles from Scientific American (I'd have thought a name like "Scientific American" would get one brought up on charges of 'High-Treason' these days), and I ran into another article on this flying Loss of Nightvison. And the opinion of the author. He touches on some things many of us haven't yet considered. So...

    I thought I might share it with any & all interested folk. And here you go - open to read, or download the Pdf. for later:

    Twinkle, Twinkle, Satellite Vermin.pdf

    Taking a 'Straw Poll' on the general public opinion on this thing - including non-astronomy sites of the news-media - most people are against this thing. The feeling is this will act as paving the way to seeing the road paved to flying "DRINK COCA~COLA!" signs and the "GOLDEN ARCHES" glowing across our skies.

    At least that's the 'good-news' of this 'Hunk-O'-Space-Junk.'

    Eventually they're going to have to cut down on space junk anyway. Otherwise serious space platforms like the ISS will be in even more danger of collisions.

    Speaking of 'space-junk,' look at what I just saw in an article on Russian Cosmonauts taking the longest space-history in order to install~repair some equipment on the ISS(Zarya):

    Electronics-Box Thrown by Russian Cosmonaut off the ISS.gif

    During the work, one of the Cosmonauts purposely tossed away what was described as being an 'old electronics' box.' "So what?" Here's what:

    The ISS is traveling at roughly 22,000 miles-per-hour, which is quite literally 'faster than a speeding bullet." So taking the formula of MASS/VELOCITY, this piece of junk would go right through a spacecraft or other satellites. And it will take a rather large computer to track it's telemetry and location so we can program everything up there to avoid a potentially catastrophic collision.

    I should hope that these astro-cosmonauts' would be better trained.

    They don't have much discipline trowing stuff like that into space.. If they are 100% sure they will burn in the atmosphere that's another story...

    Well, all the empty borscht tins they've been throwing out of Russian spacecraft for decades all burnt up on re-entry.

    I wonder if the Tesla has it turn signal on when orbiting :)
