Any of you guys ever seen "Moon Machines"? It's a multi-part documentary about the engineering behind the moon landing. Super cool.

Never, but I will try and check it out.

When it comes to Moon related documentaries, I think my fav is still Moon Shot: The Inside Story of the Apollo Project (1994)  https://www.amazon.com/Moon-Shot-Inside-Apollo-Project/dp/6303126707  The story was told from Deke Slayton's point-of-view, but sadly he passed away during the production of it (IIRC). Thankfully they got Barry Corbin to re-do the narration, and I thought he had done a GREAT job at all. Sadly I think this GREAT documentary is only available on VHS...  :(

NASA’s newest spacecraft, Orion, will be launching into space for the first time in December 2014, on a flight that will take it farther than any spacecraft built to carry humans has gone in more than 40 years and through temperatures twice as hot as molten lava to put its critical systems to the test.

Orion Multi-Purpose Crew Vehicle (MPCV) is a planned, beyond-low Earth orbit (LEO) manned spacecraft that is being built by Lockheed Martin for NASA, and Airbus Defence and Space for the European Space Agency for crewed missions to the Moon, asteroids and Mars. It is planned to be launched by the Space Launch System. Each Orion spacecraft is projected to carry a crew of 0–6 astronauts.

Holy shit.

Side note... Did they use a TIE figher sound for the fly-by at 42 seconds?

One of my favorite of the Apollo documentaries.  My favorite episode was the navigation computer.

Regarding Orion, I designed part of the pressurization system used for inflating the uprighting airbags after splashdown.  Arguably not one of the sexiest functions of the spacecraft, but keep in mind that it needs to survive every part of the spaceflight including reentry and splashdown.  I believe that system will be tested on this flight.

Also, in December it will fly on an Delta IV launch vehicle, not SLS which is not developed yet.  Eventually it is planned to fly on SLS.  I didn't watch the video, so maybe that is mentioned there.

He said hardware failure. The main computer detected a malfunction and decided that destroying the rocket was the safest avenue. Through the FIRST robotics program, I also met Tom Gavin. He's the guy who signed off on the Mars orbiter that missed Mars because part of the project was done in metric units and other parts were done in English units.

No, a subcontractor.  Basically, NASA develops the requirements and bids out the spacecraft to industry.  Lockheed is the prime contractor for the Orion crew module, who in turn subs out much of the subsystems to companies who specialize in the appropriate technology.

And it wasn't even as blatant as using feet instead of meters.  The mass moments of inertia (heavy objects are difficult to rotate, so its akin to mass making it difficult to move a heavy object in a straight line) for the spacecraft were in the wrong unit system.  The attitude control system was then using inappropriate thrust to maneuver.

Oh my, haven't heard about that. Googled a bit and yes that was one expensive brainfart!

NASA's Mars Climate Orbiter was lost in space last week because engineers failed to make a simple conversion from English units to metric, an embarrassing lapse that sent the $125 million craft fatally close to the Martian surface, investigators said yesterday.

Stunning Rosetta Images Reveal Sand Dunes on Comet 67P Churyumov-Gerasimenko
It's a large icy lump of rock that has spent millions of years hurtling through the vacuum of space, so you can imagine the surprise on the faces of ESA researchers when they discovered Comet 67P Churyumov-Gerasimenko possessed what appeared to be sand dunes. Of course, it's not sand as we know it, but instead dust that is almost inexplicably collecting on the comet's surface.



Quote
The images above were taken on October 18th with Rosetta approximately 8km away from Comet 67P, and the presence of those dusty dunes will be the focus of a great deal of study on the part of Rosetta's science team. However, most of ESA's energies will be fully focused on the events leading up to November 12th, when the Rosetta team will attempt the first soft-landing on a comet in human history.

So in the " this is news to me " category :

Apparently there is 90% gravity in space and people are only weightless in shuttles and space stations due to  free fall - which is overridden by it's horizontal motion orbiting the earth.

 :eek I've heard that twice recently. All this time I thought there was like 5% gravity in space.

That's rather all over the place.
First of all, yes indeed, if you are in orbit, the gravity of the planet is exactly counteracted by the centrifugal force.

However, that doesn't mean every point in space has that amount of gravity. Get away far enough from any star and your gravitational pull will be miniscule

Yea some backlash will happen but as gruesome as it may sound it's during accidents like this that the project becomes "safer" because they're forced to investigate and solve scenarios they didn't foresee.
