Solid oxygen , of course, why didn't i think of that?
SPACE X FINALLY KNOWS WHAT CAUSED ITS FALCON 9 ROCKET TO EXPLODE
ELON MUSK SAYS THE PROBLEM HAS "NEVER BEEN ENCOUNTERED BEFORE IN THE HISTORY OF ROCKETRY.”
By Sarah Fecht
November 7, 2016
CEO Elon Musk says the company has identified the cause of the September explosion, and the Falcon 9 could be fixed and flying by mid-December.
Yesterday Musk explained to CNBC why it took so long to get to the bottom of the explosion: “It was a really surprising problem. It’s never been encountered before in the history of rocketry.”
The problem has to do with some super-cold oxygen reacting with the carbon fiber composites within the fuel tank.
The Falcon 9 rocket flies by combusting liquid kerosene with oxygen. Because there's no oxygen in space, the rocket needs to bring its own. To pack in as much fuel as possible, most rockets cool oxygen gas until it's liquefied; SpaceX takes it one step further by cooling it even more, possibly to increase the density and thus how much fuel the rocket can carry.
Well, it turns out that the supercooled oxygen might have been too cold—cold enough to actually solidify.
SpaceX likes its oxygen tanks to be kept at about -340 degrees Fahrenheit, and the stuff ices over at -362 degrees. According to the New York Times, the liquid helium containers inside the oxygen tank could have been responsible for pushing to oxygen over the brink. Helium, which is used to pressurize the oxygen tank, is stored at even colder temperatures than oxygen, at -452 degrees.
Musk didn't elaborate on how the solid oxygen formed or what happened after that, but the leading theory is that the solid oxygen may have ignited one of three carbon composite helium containers inside the oxygen tank, triggering the explosion that annihilated SpaceX's launch pad.
"This is the toughest puzzle that we've ever had to solve," Musk told CNBC.
Now that the company has a real lead on the problem, they can get to work on fixing it. SpaceX is targeting a return-to-flight in mid-December, although

I've asked Elon to look into the sock, bagel ,teleport dilemma.
He said he would ," take it under consideration", whatever that means.
We're working on switching propellants to cafe con leche.
Sure it's more dangerous but it tastes way better.

Morning Q-sters
Have narrowed the furnace problem down to two possibilities - Wind causing backdraft or a faulty thermostat.... Went to take thermostat off and furnace came on and has been running since.
Looks cold out there...
Heading out to Pearson airport with a buddy to pick his folks up this afternoon...
Keep warm and enjoy the day

Thornetta Davis - Honest Woman
This CD has been 20 years in the making. Thornetta Davis is the Queen of Detroit’s blues scene with over 30 Detroit Music Awards to her name. She began her career with Lamont Zodiac and the Love Signs, who became The Chisel Brothers featuring Thornetta Davis when the lead singer departed. Her first solo album was released in 1996, entitled Sunday Morning Music on Seattle’s Sub Pop label. The HBO Series The Sopranos picked up “Cry” from that album and Entertainment Weekly magazine gave the CD a hugely positive review. Having opened for a host of the music scene greats and appearing on albums with the likes of Bob Seger, Davis has toured the world and garnered praise for her live performances and her music in film and television. It has been 20 years since that first CD and with it we get to hear the superb voice and music from this fantastic diva of the blues! The CD features some great guest artists, including Kim Wilson, Larry McCray, Steve McCray and Kerry Clark.
