Space News reports that the US military “has long relied on large, expensive satellites parked in fixed orbits above the Earth.” Some US Space Force leaders “believe it’s time to change that model in favor of more mobile and renewable satellites that can maneuver to avoid attack.” USSF Space Systems Command Commander Lt. Gen. Michael Guetlein said, “We’ve got to be better at dynamic space operations.” Speaking Dec. 13 at the Space Force Association’s Spacepower conference, Guetlein “said the strategic competition with China in space will require the U.S. to shift its reliance on fixed assets in preset orbits to more ‘dynamic’ systems – satellites that can move, be upgraded and adapt their tasks as needed.” The concept “was first unveiled by US Space Command’s deputy chief Lt. Gen. John Shaw, who recently retired.” He “described it as the need for satellites to maneuver away from threats or towards objects of interest.”

ULA Vulcan Centaur Rocket’s Maiden Launch Delayed to January
SPACE reports that the premiere “of the Space Coast’s newest launch vehicle, carrying a moon lander aiming for the first commercial touchdown, will likely slip to the beginning of 2024.” United Launch Alliance (ULA) “performed a wet dress rehearsal (WDR) of the company’s new Vulcan Centaur rocket over the weekend, which includes loading propellant into the spacecraft and running through launch-day procedures up to the moments before engine ignition.” However, the test did not go to plan. A social media post from ULA CEO Tory Bruno Sunday indicated the test “ran the timeline long so we didn’t quite finish.” Vulcan’s first launch, “which includes the rocket’s Centaur second stage, was scheduled for Dec. 24 from Cape Canaveral Space Force Station in coastal Florida.” But the incomplete WDR “means that window is likely out.” The next window “opens Jan. 8, and will last four days, the CEO clarified in a follow-up post.” Each of those opportunities “include an instantaneous launch window to accommodate the mission’s main payload: Astrobotic’s Peregrine lunar lander, headed for the moon.”

SpaceX’s Next Starship Flight Expected to Include Propellant Transfer Demonstration for NASA
FOR IMMEDIATE RELEASE
CNBC reports, “SpaceX could attempt a key demonstration for NASA during the third test flight of its towering Starship rocket.” According to a NASA official, “the next Starship flight is expected to include ‘a propellant transfer demonstration,’ though an agency spokesperson noted Tuesday the plan is subject to change, as is often the case in the space industry.” NASA spokesperson Jimi Russell said in a statement, “NASA and SpaceX are reviewing options for the demonstration to take place during an integrated flight test of Starship and the Super Heavy rocket. However, no final decisions on timing have been made.”

Richard Branson Says He Will Not Invest More Money into Virgin Galactic
CNN reports that shares of Virgin Galactic, “the space tourism venture founded by Richard Branson, are plunging after the British billionaire said he has no plans to invest more money in the company as he says it has ‘sufficient funds’ already.” This news contributed to Virgin Galactic’s stock falling 16% at market open on Monday. Virgin Galactic “has had a landmark year, flying its first customers to the edge of space after years of waiting.” But the company “has also been in a state of flux, having just laid off about 20% of its staff and working to introduce a new line of suborbital spacecraft that will supplant the vehicle it’s spent more than a decade developing.”

ULA Prepares for First Vulcan Centaur Launch
The Orlando (FL) Sentinel reports that United Launch Alliance “has its missing rocket piece in hand at Cape Canaveral and all systems are go for a Christmas Eve launch to mark the debut of its Vulcan Centaur rocket.” A new Centaur upper stage “arrived by barge to the Space Coast on Monday, a replacement for the stage ULA originally planned to fly on the Certification-1 mission this past May.” That initial flight, “already delayed for nearly two years, was again put on hold after an issue with a test version of the Centaur stage was destroyed amid a massive fireball in the spring, requiring design changes to ensure a repeat didn’t happen during actual liftoff.” ULA has been anxious “to get this debut launch off the ground with its primary payload of Astrobotic Technology’s Peregrine lunar lander, part of NASA’s Commercial Lunar Payload Services missions.” The lander “traveled from Astrobotic’s headquarters in Pittsburgh arriving to the Space Coast on Oct. 31.”

Curiosity Logs 4,000th Day on Mars
Phys (UK) reports that four thousand Martian days “after setting its wheels in Gale Crater on Aug. 5, 2012, NASA’s Curiosity rover remains busy conducting exciting science.” The rover recently “drilled its 39th sample, then dropped the pulverized rock into its belly for detailed analysis.” To study “whether ancient Mars had the conditions to support microbial life, the rover has been gradually ascending the base of 3-mile-tall (5-kilometer-tall) Mount Sharp, whose layers formed in different periods of Martian history and offer a record of how the planet’s climate changed over time.”

NASA’s Ingenuity Helicopter Achieves Longest Flight in 18 Months
SPACE reports that NASA’s Ingenuity helicopter “conducted its 63rd Mars flight on Thursday (Oct. 19), covering 1,901 feet (579 meters) of ground in the process.” That was “its longest distance since Flight 25,” NASA’s Jet Propulsion Laboratory said. Ingenuity “flew for 2,310 feet (704 m) on Flight 25, which occurred on April 8, 2022.” This latest sortie “lasted 143 seconds, according to the mission’s flight log.” Ingenuity “got a maximum of 39 feet (12 m) above the ground and reached a top speed of about 14.1 mph (22.7 kph).”

USSF Prioritizing Modernization of Spaceports
Space News reports that the need to “modernize US spaceports has been discussed for years, but major upgrades have yet to materialize.” With $1.3 billion in projected “funding for spaceport improvements, the Space Force is now trying to move these plans forward, identifying the most critical areas needing attention in the near-term.” Space Systems Command Program Executive Director Brigadier General Kristin Panzenhagen said, “There’s a significant effort to define what we need to be able to support the capacity and the pace of launch that our nation needs.” Based at Patrick Space Force Base, Florida, Panzenhagen in June “assumed command of Space Launch Delta 45, and oversees the nation’s busiest spaceport on the Florida coast.” Speaking last week at the AFCEA Space Industry Days conference in Los Angeles, Panzenhagen “expressed optimism that initiatives to bring East Coast and West Coast spaceports into the future could soon become reality.” The Space Force has “conducted a detailed analysis of spaceport requirements given the increased pace of commercial space launch, she said.”

NOAA Says Evidence of Rare Metals in Stratosphere Likely from Rocket Launches
The Washington Post reports NOAA researchers collected and analyzed particles in the stratosphere that indicates the presence of rare elemental metals niobium and hafnium, which “are common in spacecraft manufacturing and can be found in semiconductors, rocket chambers and other applications.” The discovery “sheds light on the environmental aftermath of a growing number of rockets, satellites and other human-made spacecraft that give off metal vapors as they reenter the atmosphere.” The researchers also “identified aluminum, lithium, copper and lead in the stratosphere – all of which are linked to alloys used by the aerospace industry.” It is still unclear “how the existence of these rare metals and other elements in the stratosphere might influence the climate.”

EU Nations Eager to Expand Human Low-Earth-Orbit Presence
Aviation Week reports that the first all-European private astronaut crew “is working toward a planned 14-day visit aboard the International Space Station (ISS) to carry out more than 30 science and technology investigations.” It is anticipated they “will have an economic potential as well as pay scientific dividends beyond those already afforded by the European Space Agency’s (ESA) long-standing partnership in the 15-nation NASA led orbital laboratory.” Axiom Space is “leading its third private astronaut mission (AX-3), which is planned for launch no sooner than January from NASA’s Kennedy Space Center aboard a SpaceX Crew Dragon capsule atop a Falcon 9 rocket.” The crew will “be Italian Air Force Col. Walter Villadei; Turkey’s first astronaut, Alper Gezeravci, a Turkish Air Force fighter pilot; and ESA project astronaut Marcus Wandt of Sweden.” The commander will “be retired NASA astronaut Mike Lopez Alegria, Axiom’s chief astronaut.”
