Will there be new moon

Answer 1

If you mean 'Will there be a new moon mission?' the answer is a certain 'Yes.' The unknown question is 'When.' Many developing countries (such as China and India) are thinking of doing so as a status symbol. ("We too have had a person on the moon!") More developed countries (USA, etc) are uneasy about sending a person there again due to cost, dangers, difficulties, and the fact that robots (such as the ones on Mars surface right now) can gather just as much information often for longer periods, at lower cost, and without risking human life.

There have been more than a few in the space agency that have admitted that had they known then what they know now of all the dangers involved, they would not have risked it at the time - at least not for a another decade or three.

For instance, it was recently learned that during a certain phase of the moon most of the surface dust on the (far side? night side?) becomes highly electric - about a few hundred volts or so as I recall, although it fades rapidly over a few days. (This occurs when the moon passes through the Earth's trailing magnetosphere, picking up a charge in the process, although unable to hold it long.) Had the earlier landing sites been poorly chosen in location and (monthly) timing, most of the (albeit 1960's level) electric equipment on the mission might have been fried, leaving the astronauts abandoned to a slow death as oxygen ran out (long before any help could have arrived). This presumes the voltage was not high enough to kill the astronauts, of course. NASA did not know of this at the time, and this is only one of the issues that makes it dangerous to send humans there.

Answer 2

Yes, the moon goes through lunar phases, including the new moon phase where it is not visible from Earth.
