Bill Nye is in Washington, DC to Support NASA

You may have heard that the federal government has shut down, but that did not stop the Planetary Society’s CEO Bill Nye from traveling to Washington, DC to protest NASA cuts. He was there with almost two dozen other organizations to protest the White House’s plans to cut 24 percent of NASA’s budget.

Highlighting the potential impact of cuts to NASA’s programs, Bill Nye stated:

The China National Space Administration is going fast, doing a lot of extraordinary missions very similar, almost mission for mission, to what the United States is doing and I’m telling you there’s going to be a Sputnik moment when Taikonauts, China National Space Administration space travelers, are on the moon in the next five years.

A recent report by the Ranking Member of the Senate’s Committee on Commerce, Science, and Transportation, titled The Destruction of NASA’s Mission, states the Trump Administration is already implementing the 2026 cuts at NASA even thought Congress has yet to approve a budget. The report summary notes:

As part of Ranking Member Cantwell’s oversight of the potential impacts of President Trump’s budget request (PBR) for Fiscal Year 2026 (FY26), Democratic staff of the Senate Commerce, Science, and Transportation have uncovered evidence of an illegal plot already in motion. Based on whistleblower documents and interviews, this staff report finds that the White House Office of Management and Budget (OMB) has been directing NASA —since early summer— to begin implementing the devastating cuts demanded in President Trump’s proposed budget for FY26, in clear violation of the Constitution and without regard for the impacts on NASA’s science missions and workforce.

Not surprisingly, the law seems to be no barrier to bad behavior for this administration, yet Mr. Nye and others are not giving in or giving up. Nor should anyone who believes NASA represents the best of what our astronomers and scientists can accomplish. The size of the proposed NASA cuts for FY 2026 are shown below. It is brutal.

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.

Audit Report: ISS Spacesuit Issues

NASA has spent a significant amount of money on the Extravehicular Mobility Unit (EMU) spacesuits used during spacewalks on the International Space Station (ISS). Even so, these suits have ongoing problems that need to be resolved given that they will be critical to the ISS mission until the decommissioning of the station in 2030.

The NASA Office of Inspector General (OIG) has reported on issues with these spacesuits in the past and recently issued a new report on the status of the spacesuits. In its September 30th report, NASA’s Management of ISS Extravehicular Activity Spacesuit, the auditors noted that the contractor maintaining the spacesuits, Collins Aerospace, is having problems, including:

…considerable schedule delays, cost overruns, and quality issues that significantly increase the risk to maintaining NASA’s spacewalking capability.

The auditors stated that lack of competition for these spacesuit services as well as ineffective contract incentives are making the problems a permanent part of the program. While NASA has promoted competition for many years, these spacesuits designed 50 years ago have not benefited from this new approach, in part because the companies that feed into the supply line are slowly disappearing.

It seems dual-use rockets are much more in demand than antique spacesuits, potentially making spacesuits one of the weaker links in the space industry.

Note: Collins Aerospace ended a separate contract with NASA last year to develop a new ISS EMU. Collins continues with its contract to maintain the current EMU.

Study Findings: Lunar Surface and Subsurface Water Revealed by Chang’e-6

Nature Astronomy abstract of the study findings:

The processes driving the formation and distribution of lunar water (OH/H2O), particularly in the subsurface, remain poorly understood. An opportunity to study subsurface water comes from lander plumes, which can displace and expose millimetre- to centimetre-sized regolith during the descent of the lander. Here we analyse data from the Chang’e-6 landing site and find that plume-disturbed areas exhibit distinct temperature and water-content patterns, which are driven by the redistribution of fine regolith. The average water content of the exposed fine regolith of the shallow subsurface is ~76 ppm, which is lower than the surface abundance of ~105 ppm measured at the surface. The Chang’e-6 landing site also contains on average approximately twice the water content than the Chang’e-5 one. Temporal variations of water content are observed at identical locations but different local times, exhibiting a minimum at local noon. We suggest that the differences in water content are correlated with the regolith glass abundance, particle sizes, depths and local times, reinforcing the hypothesis that solar wind implantation and impact gardening govern lunar water formation and distribution.

Pic of the Week: Sagittarius B2

This week’s busy image from the James Webb Space Telescope (JWST) shows the Sagittarius B2 molecular cloud, which is about 26,000 light-years away.

Here is more from NASA about the image:

Stars, gas and cosmic dust in the Sagittarius B2 molecular cloud glow in near-infrared light, captured by Webb’s NIRCam (Near-Infrared Camera). In this light, astronomers see more of the region’s diverse, colorful stars, but less of its gas and dust structure. Webb’s instruments each provide astronomers with important information that help build a more complete picture of what is happening in this intriguing portion of the center of our galaxy.
