A Soyuz-U rocket carrying a Progress M-20M space freighter lifted off early on Sunday from the Baikonur space center in Kazakhstan on a resupply mission to the International Space Station (ISS), Russia's space agency Roscosmos reported.

"The launch was carried out as scheduled, at 00:45 a.m. Moscow time [20:45 GMT on Saturday]," a Roscosmos spokesman said.

"The docking of the spacecraft with the orbital station is expected at 06.27 a.m. Moscow time [02:27 GMT] on Sunday," the official said.

Progress M-20M returns to the "short" six-hour flight path to the ISS. Previously, the Progress M-19M cargo spacecraft, launched in April 2013, reached the orbital outpost two days after liftoff.

Before that, three space freighters - Progress M-16M, Progress M-17M and Progress M-18M - also delivered their cargo to the ISS in six hours.

Progress M-20M will bring some 2.4 metric tons of fuel, food, oxygen, scientific and medical equipment to the orbital outpost.

Russia's Progress M-18M spacecraft splashes down in Pacific
Fragments of Russia's Progress M-18M space freighter sunk safely in the Pacific Ocean after re-entering the atmosphere on Friday, a spokesman for the Russian mission control center said.

The spacecraft undocked from the International Space Station shortly after midnight Moscow time and started its final journey towards a remote location in the Pacific Ocean known as the "spacecraft cemetery".

"At 4:42 Moscow time fragments of the space freighter fell in the Pacific Ocean approximately 4,000 km from New Zealand's capital Wellington", the mission control spokesman said.

The launch of the next Russian cargo spacecraft to the ISS, Progress M-20M, is scheduled to take place at 00:45 Moscow time on Sunday from the Baikonur space center in Kazakhstan.
