Conclusion of a thread explaining why Juice's observations of 3I planned for November won't be on the ground for months. (Well, perhaps the Shutdown has ended by then and we've learned whether more U.S. Mars s/c than Perseverance saw something this month.)

It is also far from Earth, on the other side of the Sun. For all these reasons, we don’t expect to receive Juice’s observations of 3I/ATLAS until February 2026. It is a long wait indeed, but it's a big space out there. 8/8

At least weather- AND comet-wise the world was a better place exactly one year ago today ... here's Tsuchinshan-ATLAS over Bochum, Germany, that evening. An easy urban naked-eye comet - they don't make these anymore. Or will Lemmon explode in glory soon while the clouds part? Yeah, right ... ;-)

Heute vor genau einem Jahr war der beste Abend, um in Bochum den Kometen Tsuchinshan-ATLAS zu bestaunen, der leicht mit bloßem Auge zu sehen war: www.facebook.com/dan.fischer.... = viele Bilder von jenem Abend, bonnstern.wordpress.com/2024/10/30/z... = ein Best-Of der gesamten Sichtbarkeit.

📣Launching SCIENCE FIGHT CLUB ✊

It’s time to take back our science.

How? We take back Congress to protect science and democracy in 2026.

We invite you to join us in building power as part of our monthly grassroots donor program.

(1/2)
Graphic titled “science fight club” in bold red blocks. Text states there are two rules - 1. Only a congress without accomplices stops trumps. 2. Once we achieve that, we disband. A small box asks, “are you in?” Website at bottom: standupforscience.net/join-science-fight-club. Tone is urgent, activist, pro-science.

I'm confused: in the announcement it says it begins on 17 Oct at 20:00 JST which would be 13:00 CEST (or 11:00 UTC) - but on www.youtube.com/live/Fxe3owb... the start time is currently displayed as 2:00 CEST on 18 Oct which would be 9:00 (a.m.) JST on that date. Just a glitch with YouTube's stream?

SpaceX webcast data consistent with a Starship orbit of -1 x 192 km, with uncertainty of about plus or minus 3 km in the perigee value. The Raptor restart raised perigee to about +52 km (but the vehicle was by then already well past apogee, at 145 km on the way down.)

How do you get the launch time down to a second? When I'm watching several launch streams simultaneously the rocket lifts off at a different time in each one - this time for example SpaceX on X and NSF on YouTube via my cable TV were 30 seconds apart ...

And the ditching of the #Starship after test #11, seen from an onboard camera and a buoy which was close but didn't look in the best direction. Anyway, everything seems to have gone just as planned this time, including aggressive reentry experiments with tiles removed and hard maneuvers.

No no. No, we won't be doing that. We won't be brushing the last two years under the carpet just because there is a current ceasefire. This is appalling, Israel should not be allowed to participate until Palestine is free and Netanyahu is behind bars for war crimes, where he belongs.

Très intéressant, et loin des poncifs sur les nantis qui font des vols suborbitaux.
Quand tu passes 20 ans à bâtir toute la sécurité/fiabilité chez SpaceX et que ton premier vol "spatial" est sur... New Shepard.

This ad about the importance of using the best lightning solutions for your workspace is brought to you from 1530 Wittenberg. The desk user M.L. recommends the illuminating dove to help you stay on task. #skystorians #academicchatter
Martin Luther sits at a writing desk, writing, and a heavenly sent dove is illuminating the room. This is a hand coloured part of a bible print from 1530. You may access a digital copy here: https://daten.digitale-sammlungen.de/~db/0011/bsb00113027/images/index.html

Not necessarily: the Portland frog costume is out of stock at Amazon (but you can still get it through various Chinese web shops).

In case you want to join the ribbet-ing party ... this particular frog costume is out of stock at Amazon but can still be ordered through several Chinese vendors. (Wonder whether we in German should get some, too, just in case ...)

The company is short on written detailled (public) papers but its engineers have given several hours of interviews - mostly found on YouTube - in which they address many technical details & challenges. Yes, it's tedious to watch (I started it months ago, never finished) but required before judging.
