There is so far 6 successful lunar missions with men landed on the moon.
Triangle is the strongest shape, which is why several triangle shaped beams on building to prevent collapse during an earthquake.
Taller buildings may have a slight advantage over short ones during an earthquake.
There could be a major earthquake in Southern California, anytime. Today, tomorrow, one month from now or 50 years from now. Life is good but uncertain.
The Arctic is the north pole, and the Antartic is the south pole.
The Arctic is a sea of ice surrounded by land. Antartica is a continent almost entirely covered with ice.
Many land mammals in the Arctic (Polar Bear, Caribou, Arctic foxes etc.). No land mammals in Antartica.
Ice reflects most the sunlight and keeps these place colder.
Space shuttles are partially reusable Earth Orbit space crafts. The U.S had 6 of them (Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavor). The U.S wound up the space shuttle program in 2011 and now rely on Russian Soyuz to take astronauts to the space station.
Lots of human hours and traffic accidents can be avoided by a driverless car, which I hope would be streets in next 10 years.
It is good to have a person to talk to during long drive.
