人类居住成为可能)，according to their new research.
4．For perspective，a day or night on the moon equals(相当于) a little over two weeks on the
earth—making long-term research(长期的研究) and habitation difficult with such extremely hot
and cold temperatures.
5．The researchers think overhangs inside of these lunar pits，which were initially(最初地)
discovered in 2009，could be the reason for the stable temperature.
6．The researchers made clear that(明确表示) NASA has no immediate plans to establish a base
camp or habitations there.
