"The most recent orbital computations make it increasingly likely that the object [the new #Kreutz comet MAPS] is a fragment of one of the comets observed by Ammianus Marcellinus in AD 363, thereby strengthening evidence in support of the contact-binary hypothesis of the Kreutz system," writes Zdenek Sekanina in https://arxiv.org/abs/2602.17626: "In this context, the comet is the only second-generation fragment of Aristotle's comet that we are aware of to appear after the 12th century. It does not look like a major fragment, but rather like an outlying fragment of a much larger sungrazer."

Also interesting: #Goddard and the Invention of the Liquid Fueled Rocket" from 10 days ago, stressing his (non-)interaction with the public and colleagues. Also: https://www.youtube.com/watch?v=pnNIMT1RBGs = the "Robert Goddard First Launch Space Centennial Kick-Off Announcement" by the city of Worcester, Mass., from February and https://www.youtube.com/watch?v=kJp6DHhfkKw = the video "Beyond Rockets" mostly on futuristic ideas.

During an event in Auburn, Mass., Saturday commemorating the 100th anniversary of Robert #Goddard launching the first liquid-fueled rocket, a speaker mentioned that in addition to the four people involved in the experiment it was also accidentally witnessed by several local children - including this father aged 10 at the time: in the recording https://www.youtube.com/watch?v=hxYYXWYLzHs#t=1h15m30s he recounts his vivid story from 1:15:30.

Before and after pictures of the rocket test 100 years ago today, from the fantastic #Goddard collection at https://commons.clarku.edu/goddardlaunch/ - articles about the historical event and its context also at https://www.collectspace.com/news/news-031626a-robert-goddard-liquid-fuel-rocket-centennial-where-nell.html (small parts of the hardware may have survived after all), https://aerospaceamerica.aiaa.org/goddardcentennial-origins/ -> https://aerospaceamerica.aiaa.org/goddardcentennial-space-craze/ -> https://aerospaceamerica.aiaa.org/goddardcentennial-legacy/ and https://www.space.com/space-exploration/2-seconds-that-changed-the-world-the-1st-liquid-fueled-rocket-launched-100-years-ago-today

A folk song written earlier this year to celebrate the 100th anniversary of the #Goddard launch: https://www.youtube.com/watch?v=jCEN_JjU02c - it captures the event and its legacy well (and makes reference to Goddard's famous cherry tree and the fact that the farm where it happened is now a golf course).

It seems likely that a bright #fireball on the morning of the 12th dropped #meteorites in #Bavaria, says the Czech analysis https://meteor.asu.cas.cz/cz/post/bolid_2026_02_12/ based on data from special cameras: the body came in slowly and at a very shallow angle, so the potential strewnfield is huge and thus a systematic search not viable, and one can only hope for discoveries by chance.

While preparing #ArtemisII for flight, NASA engineers are reviewing data after a confidence test Feb. 12, in which operators partially filled the SLS (Space Launch System) core stage liquid hydrogen tank to assess newly replaced seals in an area used to fill the rocket with propellant: https://www.nasa.gov/blogs/missions/2026/02/13/following-confidence-test-nasa-continues-artemis-ii-data-review/ - during the test, "teams encountered an issue with ground support equipment that reduced the flow of liquid hydrogen into the rocket. [...] Engineers will examine findings before setting a timeline for the next test, a second wet dress rehearsal this month. March remains the earliest potential launch window for Artemis II."

An optical transient candidate of ≲ 2-second duration captured by wide-field video observations: #transient candidate (TMG20200322) with a duration of ≲ 2 s by wide-field video observations in the direction of the Earth's shadow. TMG20200322 was detected in just two consecutive images of 1-second exposure time, with its shape becoming elongated in the second frame.

Now live on #Crew12 Arrival & Welcome Remarks.

40 years ago tonight the #Giotto spacecraft passed the nucleus of #comet #Halley at great speed: the documentary https://www.youtube.com/watch?v=eI-W8ss4x5I from back then - also at https://www.esa.int/ESA_Multimedia/Videos/Undated/Giotto_-_English with bonus material - tells the story well. A big special issue of the ESA Bulletin about the mission is at https://esamultimedia.esa.int/multimedia/publications/ESA-Bulletin-046/offline/download.pdf and other historical material like some photos is linked from https://historicalarchives.esa.int/giotto-cometary-encounters-and-archival-sources while a recording of the BBC's live coverage is at https://www.youtube.com/watch?v=QxDMdH4uzxI
