Ivanka Trump made a telephone call to the International Space Station and spoke to the crew while touring Nasaโ€™s Johnson Space Centre.

Ms Trump, who is an adviser to her father, President Donald Trump, talked to the space station crew whose members are flying 250 miles above the Earthโ€™s surface.

She also spoke to students from nearby public schools who are participating in an international robotics competition.

Her visit to the centre Thursday in Houston came during a stop on her campaign tour of Texas for Republican candidates in the November 6 midterm elections.

The White House said her appearance was intended to draw attention to students learning about science and technology.

She was accompanied by US Senator Ted Cruz, US Representative Brian Babin and state lieutenant governor Dan Patrick, all Texas Republicans facing Democratic challengers.
