Ha. The “Urban Experience Fee” unexpectedly cost us an extra $25 extra per night during our recent stay in Chicago. But look at what amenities were included:

Amazing work solving a tricky calibration problem with JWST aperture masking data! Any hope to improve ground-based systematics with this general approach?

Its much harder to help my kids with homework post-covid with no textbooks. Can’t help but wonder if the move to online resources is hurting learning across the board, but especially middle and high school.

🚀 Rideshare reality check: @planet4589.bsky.social — is there a good source for CubeSat drop-off orbits from the past 5 years? I’m modeling #STARI (a LEO formation-flying mission) and need to know the most common insertion orbits. Dream case is SSO terminator—but I’m told those are unicorns 🦄.

Bravo to the organizers of the 2025 #smallsat Conference! Lively talks, great interactions, and flawless organization — plus free coffee, ice cream, lunches, and industry socials that set a high bar. Hope #AAS and #SPIE are taking notes! ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Excited to attend my first SmallSat conference in Salt Lake City this week. Many cool CubeSat missions and innovative companies exhibiting. I’ll talk about our formation flying mission STARI later in week.

Really hate to see Stanford going back on its pledge to halt legacy admissions.

It is cool to see a movie about local Ann Arbor History funded by kickstarter!

Congratulations to the filmakers!

For those also waiting, I just got a late NSF-ATI rejection today. The letter says only 10% success rate, notably lower than historical practice.

With MRI shutdown for next year, I suspect ATI (the only other NSF instrumentation programs) will be overwhelmed!
July 15, 2025 at 12:43 PM
Ok. So NSF has officially cut funding for one of its largest instrumentation programs for next year. Hope this is temporary.

Spent time to visit Copernicus in old Krakow.

He worked at The Jagiellonian University in Krakow, the 4th oldest University in Europe, where they started out only teaching 3 disciplines: Law, Medicine, and Astronomy.

I’d like to advertise the Michigan Society of Fellows, a unique opportunity for recent PhDs to carry out cutting edge research while also developing their teaching skills.

Any Interferometrists or ELT-METISians interested?

Note early deadline Sep 15.

Fellow Astronomers:
With ApJ page charges running $3K these days, what are some alternate journals to submit to?

Ive also been disappointed by the silence of our National Academy of Sciences. Perhaps if the membership of the NAS itself was being cut by 50% we would hear more complaint.

US science is being wrecked, and its leadership is fighting the last war
Facing an extreme budget, the National Academies hosted an event that ignored it.

Reasonable NSF budget cut:
* Choose to support only one Extremely Large Telescope Project

Unreasonable NSF budget cut:
* Choose to support only one of the two essential LIGO Gravitational Wave Interferometer detector sites.

Space science is probably the only area in technology that the USA is the undisputed world leader. Squandered.
Under Trump’s budget, NASA would face its lowest funding in over a decade, and its most ambitious science missions would be canceled. Davinci+, Veritas, Mars Sample Return? Gone.

If Trump gets his way, the future of U.S. space science will die on the launchpad.

Universe’s mysteries may never be solved because of Trump’s Nasa cuts, experts say
‘Extinction-level cuts’ to space agency’s spending means labs will close and deep-space missions will be abandoned

Maybe this has been written before, but one of explanations for the increased and more widespread administrative mayhem of the new govt compared to last must be chatgpt.

I could not disagree more with revoking student visas based on nationality. As the PhD advisor of multiple international students over past 20years, there is no doubt our Country is stronger and more prosperous with their contributions.
When you can’t outcompete, just ban them. Classic.

Potentially legit reasons to withdraw tax-exempt status for Universities:
* increasing student tuition faster than inflation
* paying U Presidents >$1M/yr

Not legitimate reasons:
* defending student and faculty academic freedom
* pursuing DEI activities legally allowed by state and federal laws

Nice article summarizing some unexpected radial velocity results!
Good news for a change: It looks like WR 104, the potential source of a mind-vaporizingly powerful gamma-ray burst death ray, is not pointed exactly at Earth.

Is the WR 104 system pointing a gamma-ray burst at Earth? Probably not.
New observations indicate it’s aimed away from us
