“SpaceX then lit the center engine for a single engine burn. That relight also went well, however we exceeded the roll control authority of the attitude control thrusters. This particular stage was not equipped with landing gear which could have helped stabilize the stage like fins would on an aircraft. The stage ended up spinning to a degree that was greater than we could control with the gas thrusters on board and ultimately we hit the water relatively hard.
from the picture above it looks like it came pretty damn close! WOW!
The Gig Economy: The Force That Could Save the American Worker? BY MICHA KAUFMAN, 09.17.13
Back to the future, the steady job ‘created’ by Henry Ford and his cohort will fade from center stage after about a century of centrality, making economists’ jobs even harder. My belief that this is already happening and is part (probably a tiny part) of the official jobless recovery problem.
The Next Wireless Revolution, in Electricity : By TINA ROSENBERG : September 11, 2013
Great synopsis piece on how the spin offs of our mobile life is creating an underpinning for a financially, socially and ecologically sound human social revolution. Or at least that’s what we can hope for.

For planetary, early interstellar precursor and simple omniplanetary applications, ACMF (antimatter catalyzed fusion) exhibits the best performance. The reference case of a 1-year human round-trip mission to Jupiter with a 10 to 100 metric ton (mT) payload requires an antimatter quantity of 1 to 10 micrograms (μg). It appears as though this requirement could drop into the 1 to 10 ng range for payloads consistent with unmanned, planetary missions.
So fuel for a trip to Jupiter (in one year!) every week.
