The two-and-a-half-minute engine burn lowered the space station's altitude by 310 meters - about 1,000 feet - setting it on a new path, safely out of reach of the rocket chunk. ET, Roscosmos fired the engines of its Progress cargo spacecraft, which was docked to the ISS, pushing the orbiting laboratory closer to Earth.

NASA and Russia's space agency, Roscosmos, monitored the chunk throughout Monday, eventually deciding they needed to move the space station.Ībout two hours before the debris was set to pass the ISS, at 2:58 a.m. The International Space Station (ISS) changed course Friday to avoid a possible collision with a piece of an old Pegasus rocket.Ī chunk of that old rocket, which broke apart two years after the United States launched it into Earth's orbit in 1994, was on track to pass close to the ISS Friday morning.

MatISS-2 had four identical sample holders containing three different types of materials, installed in a single location in Columbus. This provided some baseline data points for researchers, as when they were returned to Earth, researchers characterized the deposits on each surface and used the control material to establish a reference for the level and type of contamination. The first was MatISS-1, and it had four sample holders set up in for six months in three different locations in the European Columbus laboratory module. Three iterations of the experiment have been used on the ISS.

The experiment is sponsored by the French space agency CNES and was conceived of in 2016.
