On July 3, 2015, Russian Federal Space Agency (Roscosmos) conducted successful launch of Soyuz-U launch vehicle carrying Progress M-28M cargo spacecraft on an orbital path to the International Space Station (ISS) from Baikonur spaceport in Kazakhstan.
This launch followed recent two failures to deliver a cargo spaceship to the ISS. At first, Progress M-27M vehicle mission was lost due to its deployment into an incorrect orbit on April 28. Recently, on June 28, SpaceX failed to orbit its Dragon cargo spacecraft after Falcon 9 flight anomaly on June 28.Taking into account last October's explosion of Orbital ATK's Antares rocket with Cygnus cargo spaceship, it is difficult to underestimate now the importance of this (and each next) cargo resupply mission for future human space exploration aboard the orbiting lab.
Progress M-28M made 34 orbits around the Earth during two days following the launch, and docked to the Pirs Docking Compartment of the orbiting laboratory on Sunday, July 5. In order to avoid any mistakes or orbital flight anomalies, Roscosmos chose well-proved so-called 'long scheme of flight', instead of short 6-hours scheme, used during previous several missions.
The Russian cargo spacecraft delivered to the ISS 2381 kg of cargo, which is near 100 kg more than during previous missions. According to Roscosmos, Progress M-28M cargo includes fuel, air, oxygen, scientific experiments' and other equipment, water (420 kg), food (430 kg), and crew's personal items.
