“上天入地下海”是我国几代科学家的梦想。2004年，这一梦想正在实现之中。如今，返回式卫星等常规卫星的发射已经几乎不是新闻。只有载人航天、探月等才能吸引大多数人的眼球。2004年，投资14亿元的“嫦娥一号”绕月工程在年初正式启动，预计到2007年发射第一颗绕月卫星，嫦娥奔月已“指年可待”。 “God into the sea” is the dream of several generations of scientists in our country. In 2004, this dream is being realized. Today, the launch of conventional satellites such as return satellites is hardly news. Only manned spacecraft, lunar exploration, etc. can attract most people's attention. In 2004, the “Chang'e One” round-the-moon project, with a total investment of 1.4 billion yuan, was officially launched at the beginning of this year. It is estimated that by launching the first moon satellite in 2007, the moon will be “just around the corner.”
