NASA delays the Artemis 1 moon mission for a third time as a tropical storm approaches
The launch of the uncrewed space vehicle was scheduled for Tuesday but is being pushed back because Tropical Storm Ian might hit Florida next week as a hurricane.

Bam! NASA spacecraft crashes into asteroid in defense test
A NASA spacecraft closed in on an asteroid at blistering speed Monday in an unprecedented dress rehearsal for the day a killer rock menaces Earth.
Though the impact was immediately obvious — Dart’s radio signal abruptly ceased — it will be days or even weeks to determine how much the asteroid’s path was changed.

14,760 mph 1000 lbs LICIACube (Light Italian CubeSat for Imaging of Asteroids)
T-1 sec before impact of DART upon target Dimorphos
Deployed some time (18 days) before DART’s strike on Didymos’ moonlet, LICIACube (Light Italian CubeSat for Imaging of Asteroids) was deployed from DART to record the aftermath of the Dimorphos encounter.
Weighing in @ slightly over a thousand pounds, and slamming in @ some 15,000 MPH, DART’s impact was captured by its hitch hiking buddy, LICIACube.
Plumes of ejecta sprayed out of Dimorphos. While dependent upon its composition (stony/metallic, loose/solid, etc),
It is guesstimated that the deflection of the smaller binary asteroid into a tighter orbit should be about 1%.
More massive, and higher velocity projectiles are required for higher deflection rates.
Borg Cube, @ 10,000 x 10,000 feet, should be a killer Klingon klincher
This, meanwhile, is an impressive proof of concept, hitting a 160 foot moving object some
7 million miles away:

The Tarantula Nebula, also known as 30 Doradus, is more than a thousand light-years in diameter, a giant star forming region within nearby satellite galaxy the Large Magellanic Cloud. About 180 thousand light-years away, it's the largest, most violent star forming region known in the whole Local Group of galaxies. The cosmic arachnid sprawls across this magnificent view, an assembly of image data from large space- and ground-based telescopes. Within the Tarantula (NGC 2070), intense radiation, stellar winds, and supernova shocks from the central young cluster of massive stars cataloged as R136 energize the nebular glow and shape the spidery filaments. Around the Tarantula are other star forming regions with young star clusters, filaments, and blown-out bubble-shaped clouds. In fact, the frame includes the site of the closest supernova in modern times, SN 1987A, at lower right. The rich field of view spans about 2 degrees or 4 full moons, in the southern constellation Dorado. But were the Tarantula Nebula closer, say 1,500 light-years distant like the Milky Way's own star forming Orion Nebula, it would take up half the sky.
The Perseverance rover's Mastcam-Z captured images to create this mosaic on August 4, 2022. The car-sized robot was continuing its exploration of the fan-shaped delta of a river that, billions of years ago, flowed into Jezero Crater on Mars. Sedimentary rocks preserved in Jezero's delta are considered one of the best places on Mars to search for potential signs of ancient microbial life and sites recently sampled by the rover, dubbed Wildcat Ridge and Skinner Ridge, are at lower left and upper right in the frame. The samples taken from these areas were sealed inside ultra-clean sample tubes, ultimately intended for return to Earth by future missions. Starting with the Pathfinder Mission and Mars Global Surveyor in 1997, the last 25 years of a continuous robotic exploration of the Red Planet has included orbiters, landers, rovers, and a helicopter from planet Earth.
What's happening in the Statue of Liberty nebula? Bright stars and interesting molecules are forming and being liberated. The complex nebula resides in the star forming region called RCW 57, and besides the iconic monument, to some looks like a flying superhero or a weeping angel. By digitally removing the stars, this re-assigned color image showcases dense knots of dark interstellar dust, fields of glowing hydrogen gas ionized by these stars, and great loops of gas expelled by dying stars. A detailed study of NGC 3576, also known as NGC 3582 and NGC 3584, uncovered at least 33 massive stars in the end stages of formation, and the clear presence of the complex carbon molecules known as polycyclic aromatic hydrocarbons (PAHs). PAHs are thought to be created in the cooling gas of star forming regions, and their development in the Sun's formation nebula five billion years ago may have been an important step in the development of life on Earth.
While drifting through the cosmos, a magnificent interstellar dust cloud became sculpted by stellar winds and radiation to assume a recognizable shape. Fittingly named the Horsehead Nebula, it is embedded in the vast and complex Orion Nebula (M42). A potentially rewarding but difficult object to view personally with a small telescope, the featured gorgeously detailed image was taken in infrared light by the orbiting Hubble Space Telescope. The dark molecular cloud, roughly 1,500 light years distant, is cataloged as Barnard 33 and is seen above primarily because it is backlit by the nearby massive star Sigma Orionis. The Horsehead Nebula will slowly shift its apparent shape over the next few million years and will eventually be destroyed by high energy starlight.
Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our own Milky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebula and is actually one of the brighter galaxies not included in Charles Messier's famous 18th century catalog. Since the galaxy's disk is inclined to our line-of-sight, long telescopic exposures often result in an image that evokes a strong sense of depth. This Hubble Space Telescope close-up spans some 40,000 light-years. The galaxy's magnificent spiral arms feature dark obscuring dust lanes, bright bluish clusters of massive young stars, and the telltale reddish glow of active star forming regions. The bright yellowish central regions harbor populations of older, cooler stars. Like the Milky Way, a supermassive black hole lies at the core of spiral galaxy NGC 7331.
The dust sculptures of the Eagle Nebula are evaporating. As powerful starlight whittles away these cool cosmic mountains, the statuesque pillars that remain might be imagined as mythical beasts. Featured here is one of several striking dust pillars of the Eagle Nebula that might be described as a gigantic alien fairy. This fairy, however, is ten light years tall and spews radiation much hotter than common fire. The greater Eagle Nebula, M16, is actually a giant evaporating shell of gas and dust inside of which is a growing cavity filled with a spectacular stellar nursery currently forming an open cluster of stars. This great pillar, which is about 7,000 light years away, will likely evaporate away in about 100,000 years. The featured image is in scientifically re-assigned colors and was taken by the Earth-orbiting Hubble Space Telescope.

Six thousand plus mile Debris trail of DART/Dimorphos impact imaged by
Chile’s SOAR (Southern Astrophysical Research) telescope.
Like a comet tail, the sun’s radiation pushes the debris away from the small NEO moonlet
Of Didymos.
It may take ESA’s Hera mission on October 2024 to determine if the first ever attempt at asteroid deflection was a success (or not). Hera is an analog of the Don Quixote concept.

This really sucks. If humans are getting to the point where we can deflect killer asteroids heading to earth, and develop vaccines to blunt the natural plans of pandemics, is there anything that can stop the destructive cancer of humanity?
The result of all this "protection" will be the continued destruction of the biosphere -- other life forms and habitats. What would really bite would be if, just before humans go extinct due to our own conduct, a few of us escape to the moon and Mars, spreading our habits into space.

Well, I suppose the good news then is that the moon and mars don't HAVE much of a biosphere, at least as we understand it...
So, this brings up a point. Without expressing an opinion myself I can't help but wonder if in your view, if survival of the species (ours) required destruction of our biosphere, would we be obliged to save the planet rather then ourselves? Generally and for most folks the protection of the biosphere is promoted because it's destruction might "naturally" result in our own destruction eventually, not as a moral imperative. So the question becomes is the "natural world" more "sacred" than humanity to us?

Not to worry, we have help ( note pinpoint pupils )
Until then, a student 3D printed ZEM ( Zero Emission Mobility ) sustainability EV, with CO2 scrubber, to boot
To save the planet, and it’s Artemis 1 Mission ( guesstimate launch-date 12-27 November 2022 )

Gemini North Observatory in Hawaii
Once upon a time,
Earth sported two moons.
About the size of a bathtub, and designated 2020 CD3, the heliocentric moonlet was captured by Earth’s gravitational
Field.
From 2016, to 2020 when it was first detected, it was in direct Earth orbit, around about 3-4 years.
Perturbations from our moon finally nudged the moonlet from earth, back to heliocentric orbit.
CD3 will next re-approach Earth on March 2044, but will not be close enough to be re-captured
By Earth’s gravitational field.
An aten type object (a < 1 AU), the CD3 moonlet/asteroid has an absolute magnitude of 32 (very small size)
And possibly is a C-type (Carbonaceous), from its albedo.

Alien megastructures? Cosmic thumbprint? What’s behind a James Webb telescope photo that had even astronomers stumped
In July, a puzzling new image of a distant extreme star system surrounded by surreal concentric geometric rungs had even astronomers scratching their heads. The picture, which looks like a kind of “cosmic thumbprint”, came from the James Webb Space Telescope, NASA’s newest flagship observatory...
