Platypnea or platypnoea is shortness of breath (dyspnea) that is relieved when lying down, and worsens when sitting or standing upright. It is the opposite of orthopnea. [1] The condition was first described in 1949 and named in 1969.
Patients with trepopnea in most lung diseases prefer to lie and sleep on the opposite side of the diseased lung, as the gravitation increases perfusion of the lower lung. Increased perfusion in diseased lung would increase shunting and hypoxemia , resulting in worsening shortness of breath when lying on the affected lung.
be re-implanted into the regolith as a result of the Moon's gravity; escape the Moon entirely if the particle is moving at or above the lunar escape velocity of 2.38 km/s (1.48 mi/s), or 5,328 mph (8,575 km/h); be lost to space either by solar radiation pressure or, if the gases are ionized, by being swept away in the solar wind's magnetic field.
Sinus Medii [1] / ˈ s aɪ n ə s ˈ m iː d i aɪ / (Latin sinus mediī "Middle Bay") is a small lunar mare.It takes its name from its location at the intersection of the Moon's equator and prime meridian; as seen from the Earth, this feature is located in the central part of the Moon's near side, and it is the point closest to the Earth.

Lying down also allowed feast goers to occasionally doze off and enjoy a quick nap between courses, giving their stomach a break. The act of reclining while dining, however, was a privilege ...
Based on high-resolution photographs taken by the Lunar Orbiter spacecraft, and photos and data taken by the uncrewed Surveyor landers, this list was narrowed down to five sites located near the lunar equator. They ranged between 45 degrees east and west, and 5 degrees north and south of the center of the Moon's facing side.
