Re-entry of Progress Spacecraft 42P: Have you ever wondered how the astronauts and cosmonauts onboard the International Space Station (ISS) take out the 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 ISS international partners in Russia, Japan, and Europe. After the 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 astronaut photograph highlights the reentry plasma trail of one such spacecraft, the ISS Progress 42P supply vehicle (Russian designation M-10M). The Progress is based on the Soyuz design, and can fly autonomously or under remote control from the space station. Progress 42P docked at the ISS on April 29, 2011, and was undocked and de-orbited on October 29, 2011. Astronauts on the ISS took a time-lapse sequence of the event; the image above is part of that sequence. 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 the emission of light by atoms and molecules in the upper atmosphere when they are excited by ultraviolet radiation.
