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.

Space Quote: SpaceX Delays May Sink Efforts to Beat China to the Moon

“The HLS schedule is significantly challenged and, in our estimation, could be years late for a 2027 Artemis 3 moon landing.”

-Statement by Aerospace Safety Advisory Panel (ASAP) member Paul Sean Hill, as quoted by Space News. NASA contracted with SpaceX to develop the Human Landing System (HLS) for the astronauts landing on the Moon as part of Artemis III and later missions. While Blue Origin has also been tapped by NASA to assist with later missions, SpaceX was expected to provide the initial HLS. Maybe NASA should have picked two companies to provide the initial HLS, with the second in place still assisting with later landings. The ASAP’s 2024 Annual Report highlighted the many risks related to Artemis III, including several related to the HLS (shown below). Everyone knew this was going to be difficult, and no one wants to be asked to answer “Who Lost the Moon?” Also, it is good we still have a few advisory panels left after the recent purge.

““The discovery of a potential biosignature, or a feature or signature that could be consistent with biological processes, but that requires further work and study to confirm a biological origin is something that we’re sharing with you all today that grows from years of hard work, dedication and collaboration between over 1,000 scientists and engineers here at the (NASA) Jet Propulsion Laboratory and our partner institutions around the country and internationally.”

–Statement by Katie Stack Morgan, Perseverance project scientist at the Jet Propulsion Laboratory (JPL), at a news conference earlier on Wednesday. The rock in question, found in an ancient dry riverbed in Jezero Crater, was sampled by the Perseverance rover last year. For more on the findings you can visit the NASA site here.

Space Quote: Happy Labor Day, NASA

“The agencies and agency subdivisions set forth in section 2 of this order are hereby determined to have as a primary function intelligence, counterintelligence, investigative, or national security work. It is also hereby determined that Chapter 71 of title 5, United States Code, cannot be applied to these agencies and agency subdivisions in a manner consistent with national security requirements and considerations.”

-Wording in an executive order, signed on Thursday, that eliminates the workers’ union at NASA. While NASA was set up as a civilian agency completely separate from the U.S. Air Force and U.S. Space Command, which have national security functions, that was not enough to protect it from expansive White House interpretations targeting federal workers. Other federal agencies had their unions removed earlier this year, and other joined NASA in this latest executive order, such as the National Weather Service. One might wonder why these civilian agencies are being decimated by the same White House given that they are so critical to national security, but logic has little to do with government operations these days.
