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.
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).
If the destination is forevermore, then the journey there requires a worldview where enjoyment is only one of many heavenly experiences. The hellish ones of course get worse & worse.

Eastern Sierra in the far distance. Back in 2007, M & I hiked all day in the scorching heat trying to reach Papoose Flat, where those little sharp peaks are in the distance (left of center). Had to turn around because the sun was beginning to set. Made it back to the car just in time before our water ran out.
Korea Aerospace Research Institute of South Korea is exploring the moon with Danuri.
This Pathfinder Lunar Orbiter is tasked with surveying lunar resources such as water ice, uranium, helium-3, silicon, and aluminium, and will produce a topographic map to help select future lunar landing sites.
Mission is scheduled to be launched today, 4 August 2022, on a Falcon 9 launch vehicle.

When you’re in a place of natural silence, you’re not alone, and you can feel it. Whether it’s birdcalls from miles away or the proximity of a giant tree whose warm tones you can feel, there’s a presence, It’s a quieting experience.

THAT for six thousand years
—and no one knows how many millions of ages before
—the great whales should have been spouting all over the sea, and sprinkling and mistifying the gardens of the deep, as with so many sprinkling or mistifying pots; and that for some centuries back, thousands of hunters should have been close by the fountain of the whale, watching these sprinklings and spoutings
—that all this should be, and yet, that down to this blessed minute (fifteen and a quarter minutes past one o’clock P.M. of this sixteenth day of December, A.D. 1851), it should still remain a problem, whether these spoutings are, after all, really water, or nothing but vapour
—this is surely a noteworthy thing.

Using the language of topology to describe complex systems, leads to new insights about waves and weather patterns on earth. Some features of fluid flow on Earth can be explained by principles that traditionally apply to quantum systems.
