Cmdr. Chris Hadfield watching the pad abort test via Periscope, the only astronaut reaction I've seen so far. His reaction to the boost phase is cool.

Genuine excitement and interest....he's always been keen to  space developments....Cheers...

WOW...Thank's for taking the time to post that video. It totaly blew me away and I had to watch it twice. During the first view, my mind was racing doing comparisons to the various software products I have used for design in the avionics/electonics environment the last 35 years. Physics but with different variables, these guys have taken it to a whole new level. They are pioneering design/implementation of completely new constructs to store and present massive levels of pertinent data. Being armed with these tools will radically improve their design process. Small wonder that they were able to increase the output of their engine designs.In retrospect,it takes me about an hour and a half to analyse one point of an electromagnetic spectrum in a wave guide with Maxwells equations by hand calculation.

These are exciting times with a lot more to come due to the work environment and goals set by this company.


The raw data in their sims would be measured in yottabytes (1024), but they apply wavelet compression to make it manageable. Among other things like GPU processing.

Now they're talking about clusters of NVIDIA GPU's. This is why SpaceX is hiring tons of coders, especially game coders, from Microsoft etc. etc. around their new Seattle and Silicon Valley facilities. They know how to write code optimized for GPU's.

It would only seem logical that SpaceX will have many lurking in the background monitoring their developments in this field. There are many area's of study to benefit from this such as climate science and orbital debris mitigation.

DRAGONFLY!!

CCtCap milestone #5 is a Soyuz style landing: chutes initially with a SuperDraco landing burn in the last ~10 meters. This type of landing is shown in the last couple of minutes of the below conference video.

SpaceX has aggressive schedule leading up to crew flights

Staying true to a corporate philosophy that favors high-visibility flight tests, SpaceX plans to continue wringing out major parts of the companys human-rated Dragon spaceship in a sequence of dramatic flights leading up to the capsules first crewed mission scheduled for 2017.

We have a very aggressive and exciting year ahead of us, said Garrett Reisman, SpaceXs director of crew operations and a former space shuttle astronaut.

If everything goes according to plan, SpaceX says it can send an unmanned version of the next-generation Dragon spacecraft to the International Space Station by the end of 2016. An orbital test flight with two pilots will follow in early 2017 to cap a series of test milestones leading to NASAs certification of the capsule to carry space station crews.

Development of the Dragon crew capsule called the Crew Dragon by SpaceX started several years ago. SpaceX won its first tranche of federal funding for the crew-capable spaceship in 2011.

A test of the Crew Dragon’s propulsive landing system is on tap for the fourth quarter of this year, according to a schedule of development milestones released by NASA.

I like the emphasis of space exploration being stated several times...inferring that SpaceX's acheivments with the ISS  are just a  step towards THEIR plans.

Yup....just a stepping stone and to help fund their beyond LEO developments.
