Commemorating the lunar landing from 46 years ago, here are some wonderful photographs published on The Atlantic website. Some goods ones are there that I hadn't come across before. Really. Go check them.
Let me paste just one here.
Those tiny workers are perched some 110 meters or 360 feet above the ground.
When do we learn to accept our mortality? At 60? At 20? Perhaps never. When should we?
Perhaps mot people never accept their mortality — certainly not before the time comes when you start seeing your contemporaries fall off.
Realizing that you are mortal at 60 or 70 may be a good thing. It perhaps makes people more mellow and more congenial, less abrasive, less aggressive.
If one could reach that realization earlier, it might make us better human beings.
Perhaps religion plays a role in how and when people come to terms with their mortality. For me, my idea of mortality and what lessons to learn have to all come from exceptional individuals who lived and died exemplary lives.
Learning you have an incurable disease when you are in your 30s has got to be one of the toughest things one can face in life. Perhaps after years and decades of effort, you are close to achieving some important life goal, some important professional milestone in your mid-30s but then suddenly you are told that …
New Horizons approximate distance from Earth: 3 billion miles; 4.8 billion kilometers (32.28 astronomical units) New Horizons approximate distance from Pluto: 93 million miles; 149 million kilometers (1 AU) Time for signal to reach Earth: 4 hours, 28 minutes, 31 seconds Primary communications: NASA Deep Space Network Canberra Station, Australia (70-meter antenna)
Simple calculations show that at the enormous distance of 4.8 billion kms where Pluto is, one arcsecond equals some 24,000 kms.
Hence, when they point that "big seven-foot, high-gain dish antenna" of the New Horizons spacecraft towards Earth, they've to be pretty precisely so that the signal is received in Canberra. If you are about 15 arcseconds off, instead of the Earth, you might be pointing to the Moon.
