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.
The Luna 2 was made by the Soviet Union, and it reached the Moon in 1959. The Luna 2 took a direct path to the Moon, and the journey took approximately 34 hours. The shortest trip to the Moon was undertaken in 2006 by NASA, by the probe New Horizons. New Horizons travelled at 58,000 km/hr, and arrived at the Moon in 8 and a half hours.
