I desperately want more wide-field UV with time-domain capabilities... but we did pretty good! This is the NUV coverage up through the final official data release. (A lot of the galactic plane was observed later, but after detector limits were relaxed and the photometry is suss.)

In 2017, author and programmer Leonard Richardson wrote a zine called "Tool Safety" about what he learned from writing Beautiful Soup, one of the most impactful Python libraries ever. I think often about "the best use of the power we have as computer programmers."

While working on another project, I ran across this time series of radio frequency interference (RFI) detected by NASA's Surface Moisture Active Passive (SMAP) radiometer. What most immediately stands out to me is that you can clearly see wars after ~2020.

It is not possible to "abstain from actions or speech related to societal and political events." Nobody can do this. On account of we exist in societies as political creatures. This is not a good faith request. It is a demand for complete control over speech and actions.

It looks like we are authorized to continue working on NASA grants as long as they don't require access to NASA installations or personnel. But disbursements of funds may not occur because there will not be people to review them. Orgs will have to decide if they want to float the expenses.

And wrt this issue of water in particular... the Moon needs some kind of highly sensitive "rain gauge" to establish a baseline / groundtruth.
I hope you get a chance to re-fly the ITMS, @barbylon.bsky.social.

I'm having trouble getting over the assembly environment, TBH, which I think tells the whole story. For comparison, that is Peregrine 1 (Astrobotic) on the left and the VIPER (NASA) rover on the right.

NASA science has already been permanently and irreparably harmed by the PBR. If it is allowed to go fully into effect, if Congress does not pass a NASA budget refuting it, then the devastation will be complete.

![This infographic compares China's advancing space science efforts with America's recent retreats from planned missions. The graphic is titled "China advances its space science efforts as America considers retreat" with the subtitle "As China moves forward with an ambitious slate of missions, the U.S. weighs deep cuts to NASA's science portfolio."
The comparison is organized by planetary/celestial body focus areas, with China's missions marked by green checkmarks on the left and U.S. missions marked by red X's on the right:
China's upcoming missions (green checkmarks):
Earth's Magnetic Field: Solar wind Magnetosphere Ionosphere Link Explorer, launching in 2026
Universe/Exoplanets: Xuntian Space Telescope, launching in 2026
Asteroid Apophis: Apophis Recon Swarm, proposed for 2027 launch
Exoplanets: Earth 2.0 Space Telescope, launching in 2028
Mars Sample Return: Tianwen-3, launching in 2028
Jupiter: Tianwen-4, launching in 2029
Gravitational Waves: Taiji-2, launching in 2030
Venus: Venus Atmosphere Sample Return, proposed for 2033
Ice Giant Planets: Neptune-Triton Mission, under study for 2039
U.S. canceled or terminated missions (red X's):
Magnetospheric Multiscale Mission (operational, terminated in FY26 PBR)
Nancy Grace Roman Space Telescope (cut by 58% in FY26 PBR, launching in 2027)
OSIRIS-Apophis Explorer (operational, terminated in FY26 PBR)
Habitable Worlds Observatory (under study for 2030s, 90% cut in FY26 PBR)
Mars Sample Return (in development, canceled in FY26 PBR)
Juno (operational, terminated in FY26 PBR)
Laser Interferometer Space Antenna (ESA partnership, 2030s, canceled in FY26 PBR)
DAVINCI and VERITAS (in development, 2031, canceled in FY26 PBR)
Uranus Flagship Mission (under study for 2030s, canceled in FY26 PBR)

I would like someone to please remind the Senators that "NASA's exploration goals" extend far beyond the human spaceflight program. And that the robotic and space science efforts at NASA also produce incredible benefits and returns.

If we hypothesize a near-term capability to regularly deliver large amounts of mass to the lunar surface (e.g. fusion power plants or rovers bigger than an SUV), then what is the argument for chasing (possibly) water-rich areas for (possible) long term habitation? Why not just plan to ship water?

My best guess as to the thinking here is:
Plopping a nuclear reactor down in a PSR to claim dibs is way easier and faster than landing humans. And you don't need Starship HLS. Half a dozen CLPS companies are working on landers. Astrobotic even has one already mostly built, that was meant for VIPER.

I assume that it's just ~half the annual cost (i.e. six months) of the Juno extended mission, which gets completely zeroed out in the President's budget request for FY26.

The brief summary of the cause is that the interpreter fails to raise KeyboardInterrupt in a timely fashion. But there is no brief summary of the solution. It requires navigating thread safety, managing the GIL, and preventing arbitrary code execution... while not cratering performance!
