NASA's Artemis II mission will be the first human moon mission in more than 50 years.

It’s an historic launch day as four astronauts are set to liftoff this evening on the Artemis II mission from Kennedy Space Center, Florida.

The Orion spacecraft includes an optical communication system that can produce 4K video in space during the roughly 10-day flight.

President Donald Trump will give an update on the Iran war on Wednesday, April 1, according to White House Press Secretary Karoline Leavitt. The news comes after Trump shared an updated timeline for the end of the war on Tuesday, telling reporters in the Oval Office that he expects it to be over within "two weeks, maybe three."

Trump said the US would consider a ceasefire "when Hormuz Strait is open, free, and clear. Until then, we are blasting Iran into oblivion or, as they say, back to the Stone Ages!!!"

Trump is scheduled to speak at 9 p.m. ET, and hinted that he would also use the occasion to say he is considering withdrawing the U.S. from NATO.
