Two astronauts are likely to remain stuck in space into July.
Barry Wilmore and Sunita Williams were supposed to return on the Boeing Starliner about two weeks ago after an eight day stint in space.
US Correspondent Katherine Firkin told Mike Hosking that there have been several issues including malfunctioning thrusters and helium leaks.
She says we're being told they have plenty of supplies, and worst case they can hitch a ride on Space X's Dragon Space Craft which is also attached to the International Space Station.
Firkin says it's not great news for Boeing, when it comes to their PR.
