Vorbeiflug an Erde 2029: Mehrere Landungsmissionen auf Apophis geplant
Der Asteroid Apophis wird im Frühjahr 2029 sehr nah an der Erde vorbeifliegen. Mehrere Sonden sollen in diesem Zeitraum auf ihm landen.

Whatever eagerly awaited #Kreutz #comet C/2026 A1 (MAPS) is up to - see also https://groups.io/g/comets-ml/topic/118409957 and https://nitter.net/JAtanackov/status/2035718257060036738 and https://scicomm.xyz/@qicheng@cometary.org/116262858373488354 - less than two weeks from perihelion, it has developed a long plasma tail now: https://www.facebook.com/photo/?fbid=25816609931372735 (Rhemann & Jäger yesterday with a 12 inch telescope; full and detail).

things you learn on ancestry dot com: in 1916 my second great grandfather Luigi Lorenzo Malerbi who owned a restaurant on what is now called Sydney Walton Square in San Francisco was sued for $25,000 because someone paid $1 for a dinner for four instead of $2.60 and that person somehow lost an eye over it.

Coma model fitting indicates the morphology is compatible with a ∼0.4 km diameter nucleus—likely larger than those of the minor Kreutz fragments routinely discovered with coronagraphs, and comparable to or slightly smaller than that of C/2011 W3 (Lovejoy).

So I'm finally figuring out what YouTube was *really* invented for ... bringing you documentaries about the convoluted fates of long gone SF TV shows you had enjoyed decades ago - like #AlienNation: https://www.youtube.com/watch?v=0CQhphu3VjE

Also interesting: #Goddard and the Invention of the Liquid Fueled Rocket" from 10 days ago, stressing his (non-)interaction with the public and colleagues.

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.

So the #ArtemisII FRR went "go" on all counts, they hope to roll out the stack to the pad again on 19 March and be ready to launch on 1 April at 22:24 UTC - the table of possible launch dates in April https://www.nasa.gov/wp-content/uploads/2026/01/artemis-ii-mission-availability.pdf just had another one added for 2 April.

Spitzer HST parallaxes of 13 late T and Y dwarfs: #BrownDwarfs in the solar neighborhood (d < 20pc). By combining archival Spitzer data with our own Hubble Space Telescope (HST) observations, we achieve parallax uncertainties typically around 10%. Using Spitzer and HST photometry we compare our targets with other known late T and Y dwarfs in the Solar neighborhood, confirming that there is large intrinsic scatter in the near- and mid-infrared absolute magnitudes and colors of this population, further highlighting the diversity observed spectroscopically by several James Webb Space Telescope (JWST) programs."
