The rare failed launch of the Soyuz rocket - the workhorse of manned spaceflight today - is the latest and most grave problem to beset U.S.
American astronaut Nick Hague and Russian cosmonaut Alexey Ovchinin survived a harrowing emergency landing, following the failure of the Soyuz rocket booster carrying them to space, but what does this mean for the International Space Station?
The rocket was launched was from the Baikonur cosmodrome in Kazakhstan at 0840 GMT (12.40pm UAE time). Borisov added that Russian Federation will fully share all relevant information with the U.S.
A recording of communications between the space station and NASA stated that Hague and Ovchinin had experienced 6.7 G's - about the same as Apollo astronauts felt during reentry, according to Air and Space magazine.
They landed east of the Kazakh city of Dzhezkazgan and will be taken to the Gagarin Cosmonaut Training Center outside of Moscow in Russia, NASA said. China has a human space flight capability, but it has no crew missions planned before 2020, and NASA is barred by Congress from working with the Chinese Space Agency.
The incident comes as the US has been making progress in its quest to end Russia's monopoly on manned flights to the ISS by encouraging private companies to conduct launches.
However, it later tweeted that there had been an issue with the booster from the launch and that the rocket would returning to Earth in "ballistic descend mode".
The booster suffered a failure minutes after launch.
"Search and rescue teams report they are in contact with the Soyuz crew, who report they are in good condition", Nasa wrote on Twitter.
Rescue crews are now heading towards the emergency landing site in the barren Kazakh steppe to provide support for the crew.
US and Russian officials said the crew was heading for an emergency landing in Kazakhstan at an unspecified time. "Search and rescue crews are always pre-staged in the event that something like this does happen". It is not clear at this time if that flight will be delayed as a result of the Soyuz MS-10 failure Thursday.
Thursday's aborted mission is another setback for Russia's space program.
