PRO Earthshine From ISS

jsc2024e050831 (7/26/2024) --- The Earthshine from ISS investigation involves the thorough analysis of photos taken of the Moon from the International Space Station (ISS) at specific points in the lunar cycle to study changes in the Earth’s reflectance of light, or albedo. This photo was taken by NASA astronaut Matthew Dominick in the station’s Cupola. The intensity scale has been stretched to show off the dark side. This also brings out two reflections of the lunar bright side, caused by the multiple reflections and refractions in the Cupola's thick glass. Pictures of the Moon from space can help determine whether the earthshine method for determining Earth’s albedo can benefit from the absence of an atmosphere. Image courtesy of ESA/NASA.
