Is moon travel possible?
The first time humans set foot on the moon was in 1969, when American astronauts Neil Armstrong and Edwin "Buzz" Aldrin stepped out of the Apollo 11 spacecraft. Earlier in the 1960s, there had been a number of American and Russian unmanned rockets that reached the surface of the moon, and astronauts had reached moon's orbit. From 1969 to 1972, 10 more Americans had studied its geography and composition. More than 842 pounds (382 kilograms) of dust and rock from the surface were brought back to Earth, and various scientific instruments were left on the moon to continue collecting and sending information. Since 1972, no one has been to the moon. The American Constellation program has been working for some years toward another moon landing, but funding for that program was cut in 2010. There is continued interest however, and a number of countries and private companies around the world have sent satellites into orbit and are planning manned missions to the moon.
