...have expected them to use." But why did Aldrin have so much trouble penetrating the lunar surface beyond a few inches with his core sampler? Why was he able to plant the stand for the solar wind experiment only a few feet away with such ease? Why did the blast from the LM's engine fail to carve out even a small crater...
...down to a relaxed meal and a rest. It was strange to think that while much of the U.S. slept, two Americans were also sleeping in their cramped quarters on the distant and silent moon. Some 21 hours after landing on the moon, Armstrong and Aldrin were ready to blast off in the five-ton upper stage of the lunar module. Later, they were to rendezvous and dock with the orbiting Columbia...

With the aid of periodic news reports from Houston, they were able to keep track of the progress of Luna 15, the unmanned Soviet moon probe launched from the Baikonur cosmodrome three days before their blast-off from Cape Kennedy. The Russians cloaked Luna's mission in characteristic secrecy. Some scientists speculated that it was a "scoopy" shot designed to dig up some lunar soil and return it to earth before a manned Apollo mission could accomplish the feat. Others thought it might...

The slower velocity indicated to Lovell that the Russians were trying to economize on fuel, perhaps saving it for a landing and subsequent blast-off from the lunar surface. This, he suggested, "supports the theory that Luna 15 may attempt to recover lunar rock...
