Triple Point

The triple point of pure water is at the temperature just above freezing (0.01° C) and at the pressure (0.006 atm) at which it can exist in equilibrium in all three states: liquid, solid, and gaseous.

Yes, water can freeze & boil at the same time!

The triple point is used to calibrate thermometers.

Takeoff

This Way to the Rocket Launch Live
Spinning the Engines up to Speed

Thousands of operations are performed before the rocket can leave the launch pad, and dozens of engineering cameras track these operations.

This is also a good preview of NASA’s super heavy-lift launch vehicle, the Space Launch System (SLS), mankind’s new vehicle for the next trip to the Moon.

The first flight of Artemis and the full Orion spacecraft is scheduled to launch on SEP 05.

Update: The launch date was actually Wednesday, November 16, 2022 at 6:47 AM (UTC).
