The eldest daughter of the first American astronaut Alan Shepard flew into space on a commercial flight of the Blue Origin company, 60 years after her late father.
She was among six passengers who flew a Blue Origin rocket, owned by billionaire Jeff Bezos, which was launched from Texas, reports the Voice of America (VOA).
The whole flight, with entry into space and return, took about ten minutes.
The spacecraft was named after Alan Shepard, who flew into space in 1961 as the first American and second person in the world. A decade later, Shepard walked on the moon as commander of the Apollo 14 mission.
Laura Shepard Churchley was one of two honorary passengers who did not pay for a commercial flight to space.
The other one is the host of the morning show on ABC television and former American football player Michael Streen.
The remaining four passengers are wealthy American entrepreneurs – Dylan Taylor, Ivan Dick, Lane Bess and his son Cameron.
