Brown Thrashers wear a somewhat severe expression thanks to their heavy, slightly downcurved bill and staring yellow eyes, and they are the only thrasher species east of Texas. Brown Thrashers are exuberant singers, with one of the largest repertoires of any North American songbird.
Robert Frost has mentioned about the travel times (4.5 days and 3.5 days, from earth to moon, from moon to earth respectively). I will venture to answer your other questions. The return trip to earth requires less fuel as it is the heavier body and hence its gravity is much stronger.
How long does it take the moon to go from full-moon phase to new-moon phase? The full lunar cycle is roughly 4 weeks, and from full-moon to new-moon is half the cycle, so it would take (roughly) 2 weeks to go from full to new moon.
