Space Shuttle. The three Space Shuttle Main Engines, in conjunction with the Solid Rocket Boosters, provide the thrust to lift the Orbiter off the ground for the initial ascent. The main engines continue to operate for 8.5 minutes after launch, the duration of the Shuttle's powered flight.
Internal temp? I'm making http://www.food52.com/recipe... and it's a 9 pound pork shoulder that's been in the oven for 13 hours and has reached an internal temperature of 145. I've never cooked one before. Do I pull it out when the internal temperature reaches 160? Or does it need to continue cooking above that temperature to become meltingly tender?
The USDA recommends that pork be cooked to an internal temperature of 145 degrees Fahrenheit. The federal agency says it is lowering the recommended safe cooking temperature for whole cuts of pork from 160 degrees to 145 degrees and adding a 3-minute rest time. That temperature should be measured with a food thermometer placed in the thickest part of the meat, then allowing the meat to sit for three minutes before carving or eating.
