 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. Because it's a test flight and this is a certification mission, they really want to take the time and understand what happened.
