The new-series cargo transportation spacecraft Progress MS-03, developed and built by RSC Energia, has been successfully undocked from the International Space Station (ISS), de-orbited, and brought down in the Pacific Ocean as scheduled.

According to the Mission Control Center, the cargo spacecraft departed from the docking compartment Pirs (DC-1) of the ISS Russian Segment at 17:25 Moscow Time on January 31, 2017 and began its free flight. After a while the main engine fired a de-orbit burn. The spacecraft began to descend and reentered the atmosphere. According to calculations of trajectory specialists at the MCC, its structural elements that had not burned up in the atmosphere impacted an area in the Pacific Ocean located far off the shipping lanes on January 31 at 21:24 Moscow Time.

Cargo transportation spacecraft Progress MS-03 was launched from the Baikonur launch site on July 17, 2016 and stayed attached to the ISS since July 19, 2016.
