As per reports, an unmanned Russian cargo ship has successfully docked at the International Space Station (ISS). This supply mission has been long-awaited by the US-Russian crew as the two previous supply missions ended up in failure.

The Russian cargo ship, Progress M-28M ship, carried along with it 2.5 metric tons of fuel, oxygen, water, food and other supplies. The craft was launched into orbit on Friday from the Baikonur launch pad in Kazakhstan.

Russian Mission Control said in a statement that the craft docked successfully at the ISS on Sunday in the automated mode.

It is known that the previous supply mission ended in failure in April. Another US supply mission failed when SpaceX's Falcon 9 rocket broke apart shortly after liftoff.

The mishaps were preceded by last October's launch pad failure of Orbital Sciences' Antares rocket. Antares was carrying station cargo for the American space agency NASA.

According to NASA, the Russian Progress 60 mission was loaded with 1,940 pounds of propellant, 106 pounds of oxygen, 926 pounds of water, and 3,133 pounds of spare parts, supplies and scientific experiments.

This launch was the first after SpaceX Falcon 9 rocket exploded in last month, followed by the Russian 59 mission, which spun out of control after reaching orbit.

After a list of recent mission failures, there was a lot of pressure on Russia's Progress 60 mission. But Friday's early morning launch was said to be flawless.

In addition, SpaceX founder Elon Musk said in a tweet on Sunday that the investigation by SpaceX and the Federal Aviation Administration about the Falcon 9 explosion is expected to reach its preliminary conclusions by the end of this week.
