Leo P doin it's thing!
(as an aside, we did an episode on the #mythology and #astronomy of the #constellation #Leo , where this dwarf galaxy Leo P is located -- you can listen here: https://starrytimepodcast.podbean.com/e/leo-the-lion/)

Astrospace interview with Tim Flohrer, head of the European Space Agency's Space Debris Office: "What is actually making our job more difficult today compared to a few years ago, is the rapid increase of active satellites. ... The effort we have to put today in this coordination activities is enormous, and rapidly increasing. And the complexity of the process results also in increased collision risks."

#Falcon1 failed three times before tasting success. #Spectrum is somewhat larger and more capable than Falcon 1, with performance in line with #Firefly's Alpha rocket.
The fully assembled Spectrum rocket stands about 28 meters 
tall and measures more than 2 meters in diameter. The expendable launcher is designed to haul payloads up to 1 metric ton (2,200 pounds) into #LEO https://arstechnica.com/space/2025/03/this-launcher-is-about-to-displace-the-v-2-as-germanys-largest-rocket

If you're a woman living in Dublin and either a sole trader, running a business, or vaguely considering doing so, LEO WIB group is amazing, and hands down the best fifty quid I spend each year.
You get aforementioned Weekly Coffee Zoom, a monthly in-person event, and twice a year they really push the boat out for Summmer Event and the Christmas Party.

I'm a member of the Dublin Local Enterprise Office group for Women in Business and we do weekly Zoom meetings. Sometimes it's just a coffee meetup, sometimes it's a talk from a member who shares their expertise on a niche subject.
Today that expert was me! 
My expert talk was a very condensed primer on FOSS and The Fediverse where I only uhm a million times. @mastodonie gets mentioned a bit 
For a limited time only you can watch it here!

There are reports that the brightness of some of the Chinese #Qianfan satellites is varying on short timescales. (e.g., https://www.satobs.org/seesat/Mar-2025/0049.html)
This behavior suggests that these satellites (and possibly others) from the second Qianfan launch are currently tumbling in orbit.

Exciting Supernova orbital spacecraft uses heat of the sun for thrust.
“It has the ability to maneuver like nothing else that exists in orbit; it can go from low Earth orbit or medium Earth orbit to geostationary orbits within hours or a day.”

This entire episode underpins how important it is for nations to have access to reliable satellite intelligence that can’t be cut off by one’s enemies (or “friends”). Our first war in low earth orbit is near at hand and could initiate the #KesslerSyndrome.

#spacejunk continues its acceleration. Regulate Elon’s use of low Earth orbit (LEO). It’s the only way. And give the job to the US Coast Guard, not the militarized Space Force who just add to the space junk problem by launching ever more military hardware. #LEO #SpaceX #Elon
