 And they had a problem while they were docking. Some of the small rocket motors that control the spacecraft didn't work. They got kicked out. And some of the helium, which is a gas that we use to make the propulsion, it pressurizes the propellant. There was some small helium leaks. So they closed off the helium. The helium's not leaking anymore. But I think they're really trying to focus on what caused the small rocket engines to fire.
