CaptionsRe-entry of Progress Spacecraft 42P
Have you ever wondered how the astronauts and cosmonauts on board the International Space Station (ISS) take out their trash? Several times a year, robotic spacecraft carrying a variety of items including food, water, fuel, oxygen, medical supplies, replacement parts, and research materials are launched from Earth to dock with the ISS. These spacecraft are built and launched by the ISS international partners Russia, Japan, and the European Space Agency. After its cargo has been transferred to the ISS, the spacecraft is refilled with refuse, and then undocked and de-orbited—essentially using the Earth’s atmosphere as an incinerator for both the spent spacecraft and the refuse.
This unusual astronaut photograph highlights the reentry plasma trail (image center) of one such spacecraft, the ISS Progress 42P (Russian designation M-10M) supply vehicle. The Progress spacecraft is based on the Soyuz design, and can fly autonomously or under remote control from the ISS. Progress 42P docked at the ISS on April 29 2011, and was undocked and de-orbited approximately 183 days later on October 29 2011.
The ISS was located over the southern Pacific Ocean when this image was taken. Light from the rising sun illuminates the curvature of the Earth limb (horizon line) at image top, but does not completely overwhelm the airglow visible at image top left. Airglow is caused by light emitted at specific wavelengths by atoms and molecules excited by ultraviolet radiation in the upper atmosphere.
