Tracking landmarks through the front windows of the lunar module (LM) as it flies face down, the astronauts will fire their descent engine when the craft is 50,000 ft. above the moon and 300 miles east of the planned landing site in the Sea of Tranquillity. Its forward velocity...
Using the same distance-measuring technique, with the moon as a reference point, scientists will, during the next several years, also be able to make precise measurements of the wobbling of the earth on its axis. This motion, called Chandler's Wobble, should tend to damp out with the passage...
Yet despite the recent heady accomplishments, the major questions about the moon remain unanswered: Where and how did it originate? Was it torn Eve-like from the side of the earth, or did it form separately out of the same primordial dust cloud? Was it a planetary interloper captured by...
The lunar environment is also ideal for cyclotrons and other devices that accelerate subatomic particles in a vacuum. For the same reason, electron beam-welding?which also requires a high vacuum?would be facilitated on the moon. Another joining process, cold-welding, could become an important part of lunar industry...
At about the same time, the future astronaut was taking his first close look at the moon through a homemade 8-in. reflector telescope fashioned from a stovepipe and mounted on roller-skate wheels atop a garage. The wondrous device belonged to Jacob Zint, a neighbor of the Armstrongs and...
