“Politically, China’s lunar program has demonstrated an ability to undertake cutting edge scientific programs, as demonstrated in the innovative Chang’e-4 and Chang’e-6 probes. In terms of direct military benefits, its value is more limited. China is not in a direct space race with any other state, nor is it racing to establish settlements or “space colonies.” While there are theories of how one might employ a lunar base to undertake surveillance or even kinetic operations against terrestrial targets, the costs associated with such ambitions would be enormous. Surveillance platforms on the Moon, for example, would be almost 240,000 miles from Earth. To obtain high resolution images would be enormously costly. It is not at all clear that such efforts would win a cost-benefit analysis against systems in standard earth orbits (LEO, MEO, GEO), or even air-breathing systems. Instead, the most likely military benefits are in terms of improvements in Chinese space support capabilities, thus expanding the volume of space employed for military purposes.”

-Statement by Dean Cheng, Senior Fellow at the Potomac Institute for Policy Studies, from a hearing before the House Science, Space, and Technology Committee, Space and Aeronautics Subcommittee titled “Strategic Trajectories Assessing China’s Space Rise and the Risks to U.S. Leadership.” Mr. Cheng was one of four witnesses at the hearing.

Space Quote: Goddard Space Flight Center Threatened by Cuts

“…actions taken during the last nine months threaten the workers at Goddard and their ability to lead the world in this science and exploration. Between unnecessary voluntary separations, deferred resignations, reductions in force, and other pressure, thousands of civil servants and contractors are no longer working at GSFC. Other countries with space programs from our political allies to our adversaries have been recruiting our top scientists and researchers with massive salaries, research budgets, and the promise of stability. Where the US has considered stepping back, China has made clear they are eager to step in. We can and must re-invest in the people and centers that make America the global space leader and that starts with Goddard.”

-Statement in a November 13th letter from Maryland’s Senators and Representatives to NASA’s Acting Administrator Sean Duffy regarding recent cuts at NASA’s Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. The letter included four questions to be answered by November 17th.

Space Quote: The New Galileo, or Just a Dreamer?

“This is an example from the modern world of what the Vatican did at the time of Galileo…People have their own prejudices. I don’t have any problem with that…The whole idea of doing science is to maintain an agnostic point of view, be curious, wonder over the possibilities…It’s what makes science exciting.”

-Statement by Israel-born Harvard astronomer Avi Loeb to The Times of Israel. He was referring to his submission of an academic paper about the 3I/ATLAS comet where the last sentence in the paper noted that the comet could be targeting our solar system. He was asked to remove this sentence if he wanted his paper to be published. Astronomer Loeb has made a number of controversial comments about this new comet as well as an earlier comet named ‘Oumuamua, which was the subject of his book Extraterrestrial:
The First Sign of Intelligent Life Beyond Earth.

Space Quote: It’s Raining Satellites

“Jonathan McDowell, an astronomer at the Harvard–Smithsonian Center for Astrophysics in the US, recorded an average of between one to two Starlink satellites deorbiting each day in 2025. That figure is expected to rise to around five per day as SpaceX continues to grow its space internet constellation.”

-Statement in the UK’s Independent newspaper regarding SpaceX’s Starlink satellites burning up in the Earth’s atmosphere. Given that the satellites are only expected to last 5 years and there are already 8,500 in orbit, this should come as no surprise. Fortunately, the satellites are designed to burn up after their useful life space. Of course, that does not necessarily mean that burning debris and the related pollutants are welcome. It will only get worse once Amazon and China start pumping even more satellites into orbit.

Space Quote: Surmising Planetary-mass Bodies in the Outer Solar System

“One explanation is the presence of an unseen planet, probably smaller than the Earth and probably bigger than Mercury, orbiting in the deep outer solar system…This paper is not a discovery of a planet, but it’s certainly the discovery of a puzzle for which a planet is a likely solution.”

-Statement by lead author Amir Siraj, an astrophysicist and a doctoral candidate in the department of astrophysical sciences at Princeton University, as quoted by CNN News. The presence of a new, distant planet attempts to address the tilted orbits of some distant objects in the Kuiper Belt. The issue is discussed in a recent paper by Siraj and his fellow authors titled Measuring the Mean Plane of the Distant Kuiper Belt and found in the journal Monthly Notices of the Royal Astronomical Society: Letters.
