Sending Humans to Mars

SpaceX will send humans to Mars within 10 to 20 years, according to an interview with its CEO in the Wall Street Journal. Elon Musk says his company will send people to space within three years, and he wants to colonize other planets next.

“I want SpaceX to help make life multi-planetary,” he said. “We’re going all the way to Mars, I think. Best case, 10 years, worst case, 15 to 20 years.”

SpaceX sets launch date for world's most powerful rocket

SpaceX, the American space transport company founded by PayPal and Tesla Motors co-founder Elon Musk that is responsible for the Dragon space capsule and Falcon 1 and Falcon 9 rockets, has announced a late 2013 or 2014 launch date for the world’s most powerful rocket, the Falcon Heavy. Overshadowed by only the Saturn V moon rocket that was decommissioned after the Apollo program, the Falcon Heavy will be able to carry payloads of 53 metric tons (117,000 pounds or 53,070 kg) into orbit, which is more than the maximum take-off weight of a Boeing 737-200 loaded with 136 passengers, luggage and fuel.

Richard Branson's extreme submarine

CNN interview here.

Their submersible, designed by Graham Hawkes, is one of the more interesting parts of the journey. Shaped more like a dolphin than a traditional submarine, the Virgin Oceanic craft has an operating depth of 37,000 feet--about seven miles--which means it has to be able to withstand outrageous pressure, 1,500 times that of an airplane. Constructed of carbon fiber and titanium (with a quartz dome), the craft is currently undergoing tests--at that depth, the smallest crack would result in certain death for the pilots, both due to the immense pressure (13 million pounds) and the simple fact that there exist no other vehicles capable of a rescue mission. The sub travels at a maximum of three knots, and can dive at 350 feet per minute, so a dive to the bottom of the Mariana trench and back would take around five hours.
