The space agency has published its budget request to Congress which would see funding for science projects cut by nearly a half.

NASA and Pentagon officials moved swiftly this past week to urge competitors to Elon Musk’s SpaceX to more quickly develop alternative rockets and spacecraft after President Donald Trump threatened to cancel Space X’s contracts and Musk’s defiant response.

Trump added that he has "no intention of speaking" to Musk anytime soon, saying "I’m too busy doing other things.”
