Here are some recent space-related stories of interest.

—Discover Magazine: “The Earliest-Known Astronomical Observatory in the Americas May Offer New Insights“

There was a time when Stonehenge was believed to be a kind of “Neolithic computer.” Archaeology has since corrected that misconception. Today, the evidence points strongly in another direction: to an arid hill in the Casma Valley on Peru’s northern coast, about 200 miles north of Lima. There stands Chankillo, a complex built around 250 B.C.E., considered the earliest known solar observatory in the Americas and the clearest known example of a monument designed to track the sun’s position throughout the entire year, according to a study in Science. Modest in appearance and largely absent from tourist posters and classic postcards, Chankillo has renewed attention as archaeologists report preliminary findings from ongoing excavations.

—CBS News: “NASA Juggling Piloted Moon Mission and Space Station Crew Replacement Flight“

With a space station medical evacuation safely completed, NASA is focused on two challenging missions proceeding in parallel: launching four astronauts on a flight around the moon, at the same time as the agency is planning to send four replacement astronauts to the International Space Station...The Artemis 2 mission and Crew 12’s planned space station flight present a unique challenge for NASA. The agency has not managed two piloted spacecraft at the same time since a pair of two-man Gemini capsules tested rendezvous procedures in low-Earth orbit in 1965. The agency has never flown a deep space mission amid another launch to Earth orbit.

—Royal Astronomical Society: “‘Reborn’ Black Hole Spotted ‘Erupting like Cosmic Volcano’“

One of the most vivid portraits of “reborn” black hole activity – likened to the eruption of a “cosmic volcano” spreading almost one million light-years across space – has been captured in a gigantic radio galaxy. The dramatic scene was uncovered when astronomers spotted the supermassive black hole at the heart of J1007+3540 restarting its jet emission after nearly 100 million years of silence.

Note: Please ignore the previous posting for today about the Apollo 17 mission. It’s a good story, but I will need to retell it at another time (that is, on December 19th).

Space Stories: A Dead Galaxy, Newly Discovered Cloud-9, and Preparing for Artemis II

—innovation News Network: “Astronomers Discover Ancient “Dead Galaxy” Starved by its Supermassive Black Hole“

Using observations from the James Webb Space Telescope (JWST) and the Atacama Large Millimeter Array (ALMA), researchers found that a growing supermassive black hole can slowly starve a galaxy rather than destroy it outright. The galaxy, catalogued as GS-10578 and nicknamed Pablo’s Galaxy, existed just three billion years after the Big Bang. Despite this early stage in cosmic history, it is enormous – around 200 billion times the mass of the Sun. Most of its stars formed between 12.5 and 11.5 billion years ago, indicating a rapid burst of star formation before the galaxy suddenly shut down.

—CNN: “‘Cloud-9’ is a Newly Discovered Celestial Object. It Could Help Solve a Cosmic Mystery“

Astronomers may have discovered a previously unknown type of astronomical object, nicknamed “Cloud-9,” that could shed light on dark matter, one of the biggest mysteries in the universe. …Cloud-9 is thought to be a dark matter cloud that could be a remnant of galaxy formation from the early days of the universe, according to new research published Monday in The Astrophysical Journal Letters.

—Space.com: “NASA to Roll Out Rocket for Artemis 2 Moon Mission on Jan. 17“

The first crewed moon mission in more than 50 years remains on track to launch as soon as Feb. 6. NASA announced on Friday evening (Jan. 9) that it plans to roll the Space Launch System (SLS) rocket and Orion spacecraft that will fly the Artemis 2 moon mission out to the pad for prelaunch checks on Jan. 17, weather and technical readiness permitting.

Podcast: Does the Younger Generation Even Care about Returning to the Moon?

Posted on by onespaceman2000

In a recent episode of What Next: TBD, titled “Are We Over the Moon?,” the host spoke with Joel Achenbach, freelance journalist and author of an article in Slate called Moondoggle about the upcoming Artemis missions.

The discussion covers the plans for multiple missions to the Moon, the difference in generational interest, and the confusion last year about NASA’s leadership and budget that only brings up more questions.

Overall, Mr. Achenback does not believe the younger generations have much interest in a mission to the Moon. This is a scary statement at a time that NASA is fighting to remain funded and relevant.

It is a podcast (and article) with lessons for NASA’s public relations team, assuming anyone over there is interested.

Space Quote: Houston, Discovery May Not Be Landing

“We’ve got spacecraft that are going around the moon with Artemis II, III, IV and V. One way or another, we’re going to make sure that Johnson Space Center gets their historic spacecraft.”

–Statement by NASA Administrator Jared Isaacman to CNBC when asked about the planned move of the Discovery space shuttle from the Smithsonian Museum in Chantilly, VA to the Space Center Houston museum. He said this after highlighting the costs and risks related to this proposed move. Some in Congress have opposed the move for these very reasons, in addition to it being a political gimmick by the White House that makes little sense.

Executive Order to Ensure American Space Superiority

Just as Jared Isaacman, NASA’s new Administrator, started to settle into his new post, the White House updated the nation’s space priorities.

A new executive order on Thursday, titled “Ensuring American Space Superiority,” provides clear goals for NASA, which includes:

  • Returning to the Moon by 2028, and the establishment of initial elements of a permanent lunar outpost by 2030;
  • Deploying of nuclear reactors on the Moon and in orbit, including a lunar surface reactor ready for launch by 2030; and
  • Spurring private sector innovation and investment by upgrading launch infrastructure and developing a commercial pathway to replace the International Space Station by 2030.

Adding nuclear reactors as its own goal seems a little odd since it could simply be wrapped into the first goal related to a permanent lunar outpost, but maybe this is just to kick regolith into the eyes of the Chinese who announced a similar intention.

Returning to the Moon by 2028 will certainly be a challenge, but luckily Administrator Isaacman is showing no favorites when it comes to meeting this goal. This week he made this statement about plans to return to the Moon:

I don’t think it was lost on either vendor that whichever lander was available first to ensure that America achieves its strategic objectives on the moon is the one we were going to go with.

His friend Elon Musk was certainly listening, but so far we have not heard him say that the new NASA Administrator has a 2 digit IQ. Of course, it has only been a few days, though the honeymoon is likely to be very short.
