NASA postpones SpaceX launch to fix problems with Boeing Starliner.

NASA is delaying the next astronaut launch to give Boeing more time to fix their spaceship. The launch was supposed to happen this month but will now happen in September at the earliest.

Boeing's spaceship, called Starliner, had some problems with its thrusters and leaks. Two astronauts are currently on the space station waiting to come home in the Starliner.

NASA is still deciding how to bring the astronauts back and might use a SpaceX spaceship instead. There are only two parking spots for spaceships at the space station, and both are currently full.

Boeing is testing the Starliner on the ground and in space to understand why the thrusters failed. They are also investigating leaks in the spaceship's propulsion system.

Boeing and SpaceX are both companies that NASA hired to fly astronauts to the space station. SpaceX has already launched many astronauts, but Boeing has had several problems with their spaceship.
