The propellant leak and ensuing investigation has resulted in a one-month delay to the CRS-25 cargo mission:

A SpaceX cargo mission to the International Space Station has been pushed back to no earlier than July 11 after teams discovered elevated vapor levels of propellant. [...]

Following additional inspections and testing of the Dragon spacecraft, the investigators managed to identify the source of the leak as being a faulty Draco thruster valve inlet joint, which controls the flow of propellant. [...]

This marks the second delay for the cargo resupply mission, the first delay being announced on June 6. The first delay happened after ground teams detected elevated vapor readings of mono-methyl hydrazine while loading the propellant, forcing them to stand down from the launch attempt. [...]

The NASA and SpaceX partnership continues to be a strong one. The space agency recently bought five additional Crew Dragon flights to the ISS after NASA's other commercial partner, Boeing, failed to deliver its own crew vehicle on schedule. The recent glitch with Crew Dragon, it's fair to say, likely won't have much of a bearing on this fruitful working relationship.

    Coolant leak. (not OP)

    I think parent refers to the exhaust smell, especially in cold weather, when first starting an engine.

      If the exhaust smells sweet, I'd question whether the head gasket was blown. Coolant being pumped through a cylinder and out the exhaust is going to produce that odor. Time for a compression test, I think.

        All good points, but I'm talking about a smell I notice when a brand new car is first started. Cold weather being the operative.

        To me, antifreeze has a very distinct odor, and the smell I'm referring to is not that at all. It's not all that sweet, but that's a good approximation.

        It just dawned on me: different USA states have different fuel additives, including ethanol content. They even reformulate it based on the season and temperatures. So it may be more of a thing depending on where you live, time of year, etc.

        I buy gasoline in various places, not caring about the brand, and mostly from independent places that buy gasoline from several different source refineries. So that might also be a factor. I notice the smell of the gasoline varies depending on the brand, and again, can vary even when I go to the same independent retailer. Sometimes it's almost sweet smelling. Some brands flat out stink bad.
