It worked.

The US president said he still expected Japan to step up, pointing out its heavy dependence on oil from the Gulf, but did not subject her to the scorn he's poured on NATO allies,

for their refusal to deploy forces in support of his war against Iran.

There was one awkward moment when Mr Trump, responding to a question over why the US failed to warn its allies about the Iran plans, compared it to Japan's surprise attack on Pearl Harbor in 1941.

The two leaders did, however, agree on pushing forward, with Japan's promise made last year to invest $550 billion in the US in return for lighter tariffs.

The Japanese Prime Minister's visit to Washington had originally been timed to precede Mr Trump's planned summit with Chinese leader Xi Jinping to get across Japan's concerns over China's increasing belligerence in East Asia.

The Iran conflict has now forced the US to postpone that meeting.

Jonathan Head, NASA is rolling out its giant moon rocket to the launch pad for a second time ahead of a mission to send astronauts around the moon, something not attempted in more than 50 years.

The move to the Kennedy Space Center in Florida comes after a problem with the rocket's helium system forced NASA to abandon a launch attempt earlier this month.

The hope is the rocket will launch in early April.

So it's time, tentatively perhaps, to get excited again.

And here's a reminder of the extraordinary nature of this mission from one of the crew.

Our science editor, Rebecca Murrell, told us more.

This is the second time the rocket's been rolled out to the pad.

The first was back in January.

And the rocket's had a few technical problems.

First of all, hydrogen leaks.

Later, it had helium leaks.

And engineers are really confident that they have fixed this.

So the rocket is rolling back out to the launch pad today.
