It would be interesting to see updates of the Rosetta mission. I believe the craft is about due to send out Philea lander. I know this is not a NASA mission, but still interesting from an engineering stand point.

Like the Mars stuff. Wonder when we might seriously consider a human voyage? Seems we have plenty of volunteers from what I have read. And I mean quality volunteers, not under-skilled flakes.

@GTOlover: I wrote about the Rosetta mission a couple of weeks ago.  You can find regular updates on the European Space Agency's website, esa.int.  The landing site has been chosen, and the landing is scheduled for Nov. 11.

By the way, the Mangalyaan probe that arrived at Mars just behind MAVEN is also pretty impressive.

This should be a major news story

Doesn't everyone reading this think that this should be a major news story?  It should be on the front page of every newspaper and first story of every network report.  This represents humanity's (and the planet's) path forward.  Unfortunately man's inhumanity to man gets top billing.

78, I agree. And it is a major news story--it's all over the place, if not on front pages everywhere:

Space travel, even without humans, still astonishes me sometimes. This mission is really cool and I look forward to seeing what is learned about the MAVEN's mission, as well as what's happening on Mars. Pretty incredible.

long history with NASA

Ann, composites have a long history with NASA spacecraft.  In the 1980s I worked on the Landsat spacecraft, whcih completely filled the shuttle bay.  It's main structure was a space frame made of composites.  The company I worked for made it's own composites on site.  Interestingly, one of our competitors, making commercial communications satellites, had their structures made by a company whose main market was railcar bodies.

Me too, Liz. I *love* writing anything about space. I've been nuts about it since I was a kid. The idea that we've managed to send something that's actually landed on Mars still boggles my mind, and the first pictures of the Red Planet that came back took my breath away.

Lou, I only found out a couple years ago about composites being used on spacecraft as well as military aircraft. Of course, the materials that go to Mars and elsewhere out there are souped-up versions of what gets used for applications here on earth. So I'd guess either those railcar bodies were tougher than they needed to be, or your competitors' spacecraft weren't tough enough.

More accurately, electronic supply chains supply both NASA and other streams of businesses as well, and this includes the military. Of course contractors may be different and sourcing may be classified as top secret, but the parts and the signatures on them are the same.

I think earthly issues win over extra terrestrial accomplishments. Thanks to ISIS we have a different beheading news to read every now and then on the front page of the newspaper. 

It would be nice to see if MAVEN finds some extra information about the planet, with Mangalyan at its heels (not to mention the Mangalyan project costs less than what it took to film Gravity) and this is certainly a bog story.

More bioplastic materials have entered the 3D-printable filament fray. These PLA formulations reinforced with wood or bamboo fibers will debut at the October Composites Europe show in Germany.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
GE Aviation not only plans to use 3D printing to mass-produce metal parts for its LEAP jet engine, but it's also developing a separate technology for 3D-printing metal parts used in its other engines.
