Of course, this is still better than many humans manage.

Bad news, good news: "The asteroid’s probability of impacting the Moon has slightly increased from 3.8% to 4.3%. In the small chance that the asteroid were to impact, it would not alter the Moon’s orbit." #PlanetSci #K24Y04R #LunarRealEstateValuations

The 2025 Catalina Sky Survey Monsoon Workshop will be held in Tucson, August 1-5, as a splinter session of the ADASSx Summer Software Workshop, immediately following the Rubin Community Workshop. Registration (free) and abstract submission are now open. #PlanetSci #AstroMethods #PlanetaryDefense

I wanted to call this "Agave and Adobe", but alas, the neighbor's house is stucco. The Century Plant, a rare modern example of truth in advertising, is a member of the Asparagaceae family. #CenturyPlant #PatienceSometimesPaysOff

Where's Kosmos 482? To put the current NASA shenanigans into perspective, this Venus lander outlasted the country that launched it, and is landing on another planet entirely. #PlanetSci

The future Leo XIV graduated with a BS in mathematics from Villanova, my alma mater, in 1977, the same year I matriculated with a joint major including math and astro/physics. VU math professors were some of the best I've ever had. (I ended up an agnostic with a math minor) #LeoXIV #Villanova #Math

Starlink and other megaconstellations are photobombing ground-based telescopes. And they are photobombing remote-sensing Earth-imaging satellites in higher orbits. #astronomy #space #downinfront #privilegeknowsnobounds #didanybodyfigureoutthisstuffbeforegrantingthemalaunchpermit

Cautiously optimistic. Cast looks great. Hoping it's not a sitcom. No sign on IMDB that we meet ART in the first season. I think I see how they plan to minimize the first-person narrator. I don't think it can work if they create entirely new narratives. #Pleasedonotmurdermurderbot #SanctuaryMoon

Observations from JWST and Cerro Paranal have narrowed the uncertainties for that pesky asteroid 2024 YR4 to hit the Moon on December 22, 2032. The estimated impact probability is now 3.8%. The risk for the Earth on the same date is now too low to report. Near Earth = Near Moon. #PlanetSci #MoonSci

The Franklin Mint sold America in Space mini-coins in the 1970s. At the time, my father, Lew Seaman, was the Nimbus & Landsat Program Manager at the GE Space Technology Center. Dad managed four out of the 18 robotic missions in Series 2 & 3. All these spacecraft remain in orbit. #Space #Satellites

ESA's NEO Coordination Centre (NEOCC) computes impact probabilities (tmp link: neo.ssa.esa.int/-/latest-news) including animations of the uncertainty shrinking as more observations of 2024 YR4 were reported. Note the difference between missing along-track (Earth) and cross-track (Moon). #PlanetSci

Earth's rotation is being slowed by the tides. Length of the day increases about one second every 50,000 years while the Moon recedes about a mile to carry off its angular momentum. Over human timescales, the Earth's rotation follows a random walk and sometimes speeds up. #Astronomy #Science #Time

“Vast gravitational forces have rotated the planet Earth on an axis drawn through its north and south poles,” said Dr. Elena Bilkins of the National Weather Service. “The Earth is in actuality spinning uncontrollably through space.” #YoureOnEarthTheresNoCureForThat #SamuelBeckett

Number three is a pretty accurate observation. #MyGodItsFullOfMoons

Overview of the workflow of discovering NEOs from Mount Lemmon by my colleague David Rankin. The coordination among multiple teams funded by NASA's Planetary Defense Coordination Office (PDCO) is absolutely critical to the process. Discovery is also needed for science & future mining. #PlanetSci

Assuming we get past January 20, 2028, what happens on January 19, 2038?

On-sky plot (left) of NEOs discovered over 3 days in Oct 2022. Table (right) of their various sizes and other properties. A typical batch of discoveries. One PHA. Big dots are discovery observations. NEOs move in all directions and rates, as shown, typically fading. Comments for more. #PlanetSci

Spoke too soon. (Needless to say, I am not part of the team to find these...mumble...mumble...carry the one...128 new moons.) Saturn is the god of the Capitol, time, wealth, agriculture, and liberation, according to Wikipedia. Also moons. www.minorplanetcenter.net/mpec/K25/K25... #PlanetSci

In addition to "messes", Commercial Space lacks public visibility & oversight. "It has been an uncharacteristically messy start to the year for [...] SpaceX." "Without being inside SpaceX, it is impossible to put a fine point on what precisely is happening to cause these technical issues." #Space

Data fusion comparing the period histogram of known NEOs brighter than H=22 (larger than ~140-m) versus the population model from NEO Surveyor, as well as NEOMOD3. This is only possible with contributions from multiple NASA-funded projects. (See alt text) Data from > a century's effort. #PlanetSci

Hot-wiring the Transient Universe 5 was the final one in the original poster series. I had left NOAO by the time of the meeting in 2016, and NOAO was soon descoped & reorganized. The 5th workshop was the first organized by a university department, a model that continues. (see comments) #PlanetSci

The Solar System is both crowded & empty. PHAs are asteroids large enough to cause regional destruction if they hit Earth & near enough to evolve onto a collision course over a few centuries. However, none known pose a significant risk in the near future...but then half are unknown. #PlanetSci

It's cool to land on the moon to conduct scientific research. Nothing stops a commercial company from doing this all by themselves. Rather, they rely on public funding & scientists employed by universities & non-profit institutions. #space #moon #moonlanding #IsThereAnActiveSpaceCommunityOnBluesky

Continuing with posters for the Hot-wiring the Transient Universe series, the 4th workshop was hosted by the Las Cumbres Observatory global network of telescopes. Discussions at these meetings have resulted in tools & infrastructure widely used by the community (lco.global/aeon/). #astromethods

Hot-wiring the Transient Universe 3 was hosted by Los Alamos. National Labs provide many services to the scientific community and the nation, far beyond their central remit. Workshops are one way academia and public institutions collaborate to magnify impact on science & engineering. #astromethods

Hot-wiring the Transient Universe 2 was in Santa Cruz in 2009. These meetings became a key forum for discussing software & hardware engineering & robotic operations needed to capture observations of rapid transient celestial events. The science of things that go boom in the night. #astromethods

The first Hot-wiring the Transient Universe workshop was held at the University of Arizona in June 2007. This was a joint workshop of the VOEvent working group of the Virtual Observatory & the Heterogeneous Telescope Networks Consortium. Motivated attendees made the meeting a success. #astromethods

So much yet to discover! "As the Galactic tide acts to decouple bodies from the scattered disk it creates a spiral structure in physical space that is roughly 15,000 au in length. The spiral is long-lived and persists in the inner Oort cloud to the present time." #PlanetSci
