—Politico: “NASA’s Moon Landing Mission will Include a Non-American, Harris Says“

NASA is hoping to send a group of astronauts to the moon before the end of the decade, and at least one of them won’t be American. During a National Space Council meeting Wednesday afternoon, Vice President Kamala Harris announced that an astronaut from another country will join the U.S. team…It’s a major diplomatic move for Washington as it attempts to build an international coalition in space to counter a similar initiative being pursued by China, which the U.S. believes is gearing up for future battles in orbit. Harris didn’t specify which nation will provide the astronaut.

—University of Arizona: “Recent Volcanism on Mars Reveals a Planet More Active Than Previously Thought“

A vast, flat, “featureless” plain on Mars surprised researchers by revealing a much more tumultuous geologic past than expected, according to a study led by researchers at the University of Arizona. Enormous amounts of lava have erupted from numerous fissures as recently as one million years ago, blanketing an area almost as large as Alaska and interacting with water in and under the surface, resulting in large flood events that carved out deep channels...Mars has long been thought to be a geologically “dead” planet where not much is happening. Recent discoveries have researchers questioning this notion,

—ScienceNews: “A Bar of Stars at the Center of the Milky Way Looks Surprisingly Young“

The biography of our home galaxy may be due for some revisions. That’s because a bar-shaped collection of stars at the center of the Milky Way appears to be much younger than expected. The bar is a prominent feature of our galaxy. It spans thousands of light-years and links the galaxy’s spiraling arms of stars, making them resemble streams of water coming from a spinning lawn sprinkler.

—Reuters: “Tom Hanks Brings Love of Space to New Immersive London Show“

Archive footage of space rockets taking off beam across giant walls in a new immersive show in London, as Hollywood actor Tom Hanks narrates the story of human voyages to the moon. “The Moonwalkers: A Journey With Tom Hanks” looks at the first moon landings of the Apollo missions from 1969 to 1972 and their successor, NASA’s human spaceflight program, Artemis. The next mission – the Artemis II lunar flyby – is planned for next year and interviews with the four-member team are also projected on the walls at the Lightroom gallery space in London’s King Cross area.

—Max Planck Institute for Solar System Research: “Giant Doubts About Giant Exomoons“

Just as it can be assumed that the stars in our Milky Way are orbited by planets, moons around these exoplanets should not be uncommon. This makes it all the more difficult to detect them. So far, only two of the more than 5300 known exoplanets have been found to have moons. A new data analysis now demonstrates that scientific statements are rarely black or white, that behind every result there is a greater or lesser degree of uncertainty and that the path to a statement often resembles a thriller. In observations of the planets Kepler-1625b and Kepler-1708b from the Kepler and Hubble space telescopes, researchers had discovered traces of such moons for the first time. A new study now raises doubts about these previous claims. As scientists from the Max Planck Institute for Solar System Research and the Sonnenberg Observatory, both in Germany, report in the journal Nature Astronomy, “planet-only” interpretations of the observations are more conclusive.

—The University of Kansas: “Scholars Say it’s Time to Declare a New Epoch on the Moon, The ‘Lunar Anthropocene’“

Human beings first disturbed moon dust Sept. 13, 1959, when the USSR’s unmanned spacecraft Luna 2 alighted on the lunar surface. In the following decades, more than a hundred other spacecraft have touched the moon — both crewed and uncrewed, sometimes landing and sometimes crashing. The most famous of these were NASA’s Apollo Lunar Modules, which transported humans to the moon’s surface to the astonishment of humankind. In the coming years, missions and projects already planned will change the face of the moon in more extreme ways. Now, according to anthropologists and geologists at the University of Kansas, it’s time to acknowledge humans have become the dominant force shaping the moon’s environment by declaring a new geological epoch for the moon: the Lunar Anthropocene.

—Science.org: “Moon’s Scientifically Important Sites could be ‘Lost Forever’ in Mining Rush“

Science and commerce may be headed for a clash on remote terrain: the Moon. For the first time in half a century, NASA is sending a craft to the lunar surface, with the launch at the end of this year of Peregrine Mission 1, a lander built by the private company Astrobotic Technology. Dozens of other craft will soon follow, many as part of NASA’s Artemis program to return astronauts to the Moon. Most researchers are looking forward to a new golden age of exploration and science. But some are worried. They foresee that the advent of private landers will lead to a “Moon rush,” as companies race to grab valuable minerals and resources while trampling over scientifically important lunar sites. With space law offering little or no protection to these areas, researchers are starting to lobby governments and international agencies to do something before it’s too late.

—SciTechDaily: “Unusually Massive” – Astronomers Discover a Planet That Shouldn’t Exist“

Researchers at Penn State have discovered an unusually massive planet, LHS 3154b, orbiting an ultracool dwarf star. This finding, contradicting current theories, prompts a reassessment of star and planet formation processes. The discovery of a planet that is far too massive for its sun is calling into question what was previously understood about the formation of planets and their solar systems, according to Penn State researchers. In a paper published on November 30 in the journal Science, researchers report the discovery of a planet more than 13 times as massive as Earth orbiting the “ultracool” star LHS 3154, which itself is nine times less massive than the sun. The mass ratio of the newly found planet with its host star is more than 100 times higher than that of Earth and the sun.

—New Scientist: “Passing Star Could Fling Earth Out Past Pluto into the Oort Cloud“

If a passing star came near the solar system, Earth would probably be fine – but there is a small chance our entire world could get thrown to the outer reaches of the solar system, crash into another planet or even get stolen by the wandering star. The other planets in the solar system could suffer similar fates, and Mercury in particular would be at risk of falling into the sun.

—Forbes: “Modern Space Race: Japan Pledges $6.6 Billion For Developing Space Sector As U.S. And China Plan Historic Missions“

The Japanese government has said it will establish a $6.6 billion (¥1 trillion) fund to develop the country’s space industry as programs in the U.S., Russia, China and India rush to put men on the moon, build lunar sites and plan for the future of the International Space Station in a renewed race for celestial supremacy...Nikkei, a Japanese newspaper, reported that funding will be given to companies developing technologies that could be used to support national security or those that could rival Elon Musk’s SpaceX by developing rockets and “satellite constellations”—groups of satellites that operate as one system.

—PayloadSpace.com: “SpaceX Announces a Starship Version Two is in the Works“

With just two Starship integrated test flights under its belt, SpaceX announced last week it is already working on a major overhaul of its second-stage Starship vehicle. The design changes will be significant enough to speciate the ship, giving it the title of Version 2. SpaceX plans to finish and launch four or five additional Starship V1 prototypes before transitioning to its V2 product line, Elon Musk said on X. Insights gained from the upcoming flights will be integrated into the next-gen rocket.

—Center for European Policy Analysis: “Russia’s Earthly Aggression Cripples its Celestial Plans“

When the US imposed sanctions to degrade Russia’s aerospace industry, including embargoes on semiconductors, lasers, sensors, and navigation equipment, Dmitry Rogozin, then chief of Russia’s space program, warned it might cause the International Space Station to fall on the US or Europe. These comments and others from a supposedly serious scientific organization did cause a crash — the decades-old US-Russia space partnership was effectively ended after decades of joint work, including the Soviet era, that had benefited science, détente, and humanity. The events of 2022-2023 have made it more likely Russia would step away from exploration and, with China, focus on military applications in space.

—SpaceNews.com: “NASA Acknowledges Possibility of Short-term Post-ISS Gap“

While NASA seeks to maintain an uninterrupted human presence in low Earth orbit, an agency official said a short-term gap between the International Space Station and commercial successors would not be “the end of the world.” NASA’s current approach to its future in LEO counts on supporting development of commercial space stations with the goal of having at least one such station ready to support NASA astronauts and research by 2030, when the ISS is scheduled for retirement. A key question, though, will be whether any of the several companies working on such concepts will be ready by the end of the decade.

—KRON4 News: “Hundreds of California Jobs at Stake if NASA Mars Mission Axed“

Hundreds of tech and science jobs will be lost in California if NASA moves forward with a plan to cut funding from the Mars Sample Return (MSR) mission, according to state lawmakers. U.S. Senator Alex Padilla (D-Calif.) and Representative Adam Schiff (D-Calif.-30), sent a letter on Wednesday to NASA Administrator Bill Nelson to reverse a decision to slash the mission’s funding. The funding cut would “result in the loss of hundreds of California jobs, prevent the Jet Propulsion Laboratory (JPL) from making its 2030 launch window, and lead to the cancellation of billions of dollars in contracts supporting American businesses,” the lawmakers wrote.

—Space.com: “Canada Assigns Astronauts to Launch on Boeing’s Starliner, Back up Artemis 2 Moon Mission“

The Canadian Space Agency announced two astronauts will fly to space in the coming years on Wednesday (Nov. 22) as the country continues a historic ramp-up of its human space program in 2023. François-Philippe Champagne, the Minister of Innovation, Science and Industry of Canada, announced the assignments in front of a crowd of hundreds gathered in the lobby of Canadian Space Agency headquarters in Longueuil, Quebec.
