Reply to comment by Smartnership in TIL: Thanks to poor internal communication at NASA, information about a spacesuit water leak wasn't properly communicated. Later, Astronaut Luca Parmitano almost drowned on a July, 2013 ISS space walk, his helmet filling with several liters of water before they could get him back inside. by OvidPerl

The pressure in space is essentially zero, so water boils instantly.

Yes, but boiling does not mean hot. It would be boiling at the same temperature, or cooler, as it was before the suit was opened

Much cooler. The heat of vaporization of water is 5.4x the calories to take the water from 0 C to 100 C. It's even a good multiple of the enthalpy of fusion. Most of the water would freeze if it stays in one place. I think it'd be roughly -50 C, based on some videos I looked up about vacuum chambers.
