tldr; Chandrayaan 3, currently, stationed on the moon's south pole, detected some seismic activity of still unknown origins, using the Lunar Seismic Activity payload (ILSA) onboard.

Continued fallout from the explosion of the Centaur upper stage on ULA's test stand as Vulcan's launch continues to slip.

In a statement, ULA described the work needed on the Centaur V upper stage as “minor reinforcement at the top of the forward dome,” or the uppermost section of the liquid hydrogen tank. The changes will add strength to the tank, which contains super-flammable fuel chilled to minus 423° Fahrenheit (minus 253° Celsius).

The pressure is on as the DOD is eagerly waiting for Vulcan.

The US Space Force is eager for the Vulcan rocket to enter service. The Pentagon selected ULA and SpaceX in 2020 to launch around 40 of the military’s most critical surveillance, communications, and navigation satellites from 2022 through 2028. ULA won the rights to launch about 60 percent of the missions, primarily using the new Vulcan rocket, with SpaceX taking the remaining 40 percent with its Falcon rocket family.

From phys.org

"This cloud of orange and red, part of the Sh2-284 nebula, is shown here in spectacular detail using data from the VLT Survey Telescope, hosted by the European Southern Observatory (ESO). This nebula is teeming with young stars, as gas and dust within it clumps together to form new suns. If you take a look at the cloud as a whole, you might be able to make out the face of a cat, smiling down from the sky.

The Sh2-284 stellar nursery is a vast region of dust and gas and its brightest part, visible in this image, is about 150 light-years (over 1400 trillion kilometers) across. It's located some 15,000 light-years away from Earth in the constellation Monoceros.

Nestled in the center of the brightest part of the nebula—right under the cat's nose—is a cluster of young stars known as Dolidze 25, which produces large amounts of strong radiation and winds. The radiation is powerful enough to ionize the hydrogen gas in the cloud, thereby producing its bright orange and red colors. It's in clouds like this that the building blocks for new stars reside.

The winds from the central cluster of stars push away the gas and dust in the nebula, hollowing out its center. As the winds encounter denser pockets of material, these offer more resistance, meaning that the areas around them are eroded away first. This creates several pillars that can be seen along the edges of Sh2-284 pointing at the center of the nebula, such as the one on the right-hand side of the frame. While these pillars might look small in the image, they are in fact several light-years wide and contain vast amounts of gas and dust out of which new stars form.

This image was created using data from the VLT Survey Telescope (VST), which is owned by The National Institute for Astrophysics in Italy, INAF, and is hosted at ESO's Paranal Observatory in Chile. The VST is dedicated to mapping the southern sky in visible light and makes use of a 256-million-pixel camera specially designed for taking very wide-field images. This image is part of the VST Photometric Hα Survey of the Southern Galactic Plane and Bulge (VPHAS+), which has studied some 500 million objects in our home galaxy, helping us better understand the birth, life, and eventual death of stars within our Milky Way."

I witnessed the almost turquoise fireball while on a walk with my dogs. Since reporting it today morning, the event report features two pretty good videos of the meteor.

"The postponement is motivated by obligatory compliance with the prevention of forest fires... as well as the high temperatures" in southern Spain "to ensure the safety of the area where the launch is carried out".

First time I have seen this cited as a reason for a launch delay.
