Kate Winslet is intent on traveling to outer space.

The 36-year-old actress recently shared her desires to explore space travel with Sir Richard Branson, her boyfriend Ned Rocknroll's uncle.

The Virgin Airlines CEO is attempting to commercialise flights to space and Kate has expressed an interest in booking a seat.

"She wants to go to space," Richard revealed to Life & Style magazine.

"I'm not sure she wants to go on a one-way trip to Mars, but she wants to go to space."

The Titanic star met Ned after saving Richard's mother from a fire at his Caribbean estate.

The pair have been dating since August 2011.

"Fortunately, the one good thing that came out of the fire was this romance," Richard mused.

"They're both very outward going and seem extremely happy together."

Kate has even introduced Ned to her two children, Mia, 11, whom she had with former husband Jim Threapleton, and Jack, eight, whom she shares with ex-husband Sam Mendes.
