Donald Trump spent some quality time with Elon Musks son X as the two boarded Marine Force One together.

The president was spotted walking side-by-side with the exuberant four-year-old on the White Houses South Lawn on Friday.

He then helped the youngster, whose full name is X Æ A-Xii, up the stairs onto the aircraft.

X was joined by his father Musk, a senior adviser to the president who spearheads the Department of Government Efficiency.

The group were on their way to Palm Beach, Florida where the president is expected to spend the weekend at his Mar-a-Lago resort.

The president took off as NASAs beleaguered mission to rescue two stranded astronauts finally launched, setting the stage for a happy ending to the nine-month-long saga.

The SpaceX Falcon 9 rocket successfully took off Friday night from NASAs Kennedy Space Center, on a mission to deliver four new astronauts to the International Space Station (ISS).

The new team is scheduled to arrive at the station on late on Saturday. Once there, astronauts Sunita Williams and Butch Wilmore will finally be able to return to Earth at some point on or shortly after March 19.
