NASA astronauts stay longer in space because of problems with Boeing's capsule.

Two NASA astronauts went to space in a new capsule made by Boeing. They were supposed to come back in a week but are still there after three weeks.

There were some problems with the capsule's engines, so NASA is taking more time to make sure it's safe. The astronauts are not in danger and can use the capsule to leave quickly if needed.

Five of the capsule's engines stopped working when it was docking with the space station. NASA thinks this happened because the engines got too hot, and they are doing more tests on the ground.

The capsule also had some small leaks, but NASA says these are not a problem and there is enough fuel. Boeing, the company that made the capsule, is still trying to figure out how to fix the leaks permanently.

The astronauts are helping out with work on the space station while they wait to come back to Earth. NASA says there is enough food and supplies for everyone on the space station.
