Here's a dawn that I captured last night from the ISS HDEV cam.

I managed to capture an absolute real dawn from low orbit a few minutes earlier at the exact moment when the first rays of sunlight reflected off the ISS solar panels.

Artemis 1 Mission test flight to send an uncrewed Orion capsule on a 42-day voyage around the moon. Due to be launched today, now.

SCRUB. NASA launch director Charlie Blackwell-Thompson has called off today's Artemis 1 launch attempt due to an issue with an engine bleed on the core stage.

Launch scrubbed again. Leak in the booster hydrogen tank when they were filling it, one of the seals. Could not fix.

Kennedy Space Center, Florida (CNN)
NASA has once again waved off an attempt to launch its massive new moon rocket on an uncrewed test mission because of technical issues. The scrub was called at 11:17 a.m. ET, three hours before the beginning of the launch window.

NASA administrator Bill Nelson said that the mission managers will hold a meeting to discuss the next steps and determine if a launch is possible on Monday or Tuesday, or if the rocket stack needs to be rolled back into the Vehicle Assembly Building. The agency will hold a press conference at 4 p.m. ET to share an update.
Artemis I had been slated to take off Saturday afternoon, but those plans were scrubbed after team members discovered a liquid hydrogen leak that they spent the better part of the morning trying to resolve. Liquid hydrogen is one of the propellants used in the rocket's large core stage. The leak prevented the launch team from being able to fill the liquid hydrogen tank despite trying various troubleshooting procedures.

The reason it's giving so many challenges is that many of the materials are leftovers from the shuttle program.

NASA Exoplanets
@NASAExoplanets
From the calcium in our bones to the iron in our blood, we really are made from starstuff. It's even in our DNA – carbon, hydrogen, oxygen, nitrogen and phosphorus were all forged in ancient stars and distributed throughout the universe to become planets, puppies and you!

All the Hydrogen and Helium around us was formed at the Big Bang, not in stars. The hydrogen molecularly bonded in our skin, bones, DNA, teeth, hair, of all of it started 13.8 billion years ago. We are part of that event directly.

NASA is throwing a spacecraft at an asteroid

If Monday Night Football tackles aren’t exciting enough, NASA engineers have a much bigger collision planned this Monday at 7:14pm ET. That’s when one of their spacecraft is expected to ram into an asteroid. The first-of-its-kind test is a defensive measure to save humanity from Littlefoot’s fate, if and when that becomes necessary.

The $325 million Double Asteroid Redirection Test (DART) kicked off last fall, when the spacecraft that’s currently hurtling toward an asteroid was launched. Now, the 1,260-pound spacecraft is cruising along at nearly 15,000 mph on the final leg of its journey to crash into an 11 billion-pound asteroid moonlet called Dimorphos. The impact will be like “running a golf cart into a Great Pyramid,” planetary scientist Nancy Chabot said.

IMG_9645.JPG


The purpose: To slightly alter Dimorphos’s orbit around a larger asteroid, Didymos, because engineers think changing a celestial body’s trajectory could be the best way to keep it from hitting Earth. So no, DART won’t make the sci-fi trope of blowing an asteroid into a million pieces a reality, but the crash is expected to form a small crater in Dimorphos and shoot about two million pounds of debris into space.

And don’t worry, Dimorphos is being targeted because it is not a threat to Earth. In fact, NASA has determined that there is no known asteroid large enough to threaten Earth with a “significant chance” of crash-landing here within the next century.

DART serves a secondary purpose: It could lead to a better understanding of how the solar system was formed, since an asteroid is “a fossil of the early solar system,” NASA scientist Katherine Calvin said.

Looking ahead…telescopes around the world and space should see a bright flash upon impact, but determining whether DART successfully altered Dimorphos’s course could take weeks. NASA said there’s less than a 10% chance its spacecraft misses its target.

The probe is not expected to survive the crash, but a small, Italian-built satellite that was deployed as part of the mission will fly within 25 to 50 miles of Dimorphos a few minutes after the impact to snap photos of the aftermath.

Astronomers have seen many galaxies gravitationally interacting with each other, but never before of this particular angle which shows a three-dimensional aspect.

Tidal interaction between the barred spiral galaxy NGC 169 (bottom) and the galaxy IC 1559 (top).
A stunning new image from the NASA/ESA Hubble Space Telescope captures an ongoing interaction between two active galaxies in the Arp 282 system. Feb 2022.

NASA’s James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light.

(JWST Image)

The Pillars of Creation were first made famous when imaged by NASA’s Hubble Space Telescope in 1995.
Located in the Eagle Nebula, in the Serpens constellation, some 6,500–7,000 light-years from Earth.
