Cosmonauts Conclude Russia’s 28th Spacewalk from Station
Flight Engineers Dmitry Kondratyev and Oleg Skripochka re-entered and closed the hatch on the Pirs airlock, concluding Russia’s 28th spacewalk from the International Space Station. The 4-hour, 51-minute spacewalk ended at 1:21 p.m. EST.
The spacewalking duo installed a pair of experiments outside the station’s Russian segment. The Molniya-Gamma experiment will observe radiation emitted during Earth-bound lightning and thunderstorms. The second experiment, Radiometria, will collect seismic information to better predict earthquakes.
The cosmonauts also removed and jettisoned a spacewalk foot restraint. The restraint, which was attached to the Zvezda service module, was jettisoned towards Earth in the opposite direction of the space station’s flight path.
Kondratyev and Skripochka then translated to the Zarya control module and retrieved two Komplast panels. The panels contain materials exposed to the outer space environme
