People first set foot on the moon on July 20, 1969.
Astronauts Neil Armstrong and Buzz Aldrin stepped from the
Apollo 11 spacecraft and planted an American flag on the
moon's rocky surface. Six NASA lunar missions followed
over the next few years, and 10 more astronauts walked the
lunar surface. Then the United States government stopped
funding such missions. NASA hasn't sent a crew to the
moon since 1972.
The United States government was afraid to try to send
people into space.
NASA determined it was less expensive to send satellites
to the moon instead of people.

Lunar missions were strong for a few years until NASA
ran out of money to support them.

" "it isn’t that," said scrooge, heated by the remark, and speaking unconsciously like his former, not his latter, self. "it isn't that, spirit. he has the power to render us happy or unhappy; to make our service light or burdensome; a pleasure or a toil. say that his power lies in words and looks; in things so slight and insignificant that it is impossible to add and count ’em up: what then? the happiness he gives, is quite as great as if it cost a fortune." he felt the spirit's glance, and stopped. "what is the matter? " asked the ghost. "nothing particular," said scrooge. "something, i think? " the ghost insisted. "no," said scrooge, "no. i should like to be able to say a word or two to my clerk just now. that's all."
