Three astronauts have landed safely back on Earth after their flight home was delayed by a Russian rocket failure.
After spending 199 days at the International Space Station, Anton Shkaplerov from Russia, Terry Virts from the US and Samantha Cristoforetti from Italy, returned to Earth.
Their return marks the end of Expedition 43.
A NASA commentator described their landing as "a textbook homecoming”.
The three astronauts undocked from the station at 11.20am Irish time and landed at 2.40pm southeast of Kazakhstan. NASA Television is airing live coverage of the landing.
The Expedition 44 crew members, Commander Gennady Padalka from Russia, Scott Kelly from the US and Mikhail Kornienko from Russia, have already arrived at the station and will continue the research and maintenance.
They will be joined by three additional crew members in late July.
The head of Russia’s Roscosmos space agency, Igor Komarov, said a supply ship will be sent up to the ISS in early July, after one crashed back to Earth in early May after a rocket failure.
The Expedition 43 crew members were originally due to leave the space station on 12 May.
Their departure was delayed when a rocket carrying a cargo ship with supplies for the ISS failed shortly after launch on 28 April, causing it to fall back to Earth.
Russian Federal Space Agency Roscosmos said the problem was caused by a design fault in the rocket and not by a defect in production.
Because of the delay, Ms Cristoforetti set a record for the longest space journey by a woman. Her 199 days in space broke the old record previously held by Sunita WIlliams, who was in space for 194 days in 2007.
Russia's space programme was hit by two failures within weeks in May, with the cargo ship crash followed by the failure of a rocket carrying a Mexican satellite.
