While no official announcement has come on Shijian-25 and Shijian-21's activities during the past year, the two spacecraft are now heading away from each other following a likely refueling demonstration Details -> www.china-in-space.com/p/shijian-25...

Had my last Chandra senior staff meeting this morning; filled in my Smithsonian timesheet for the last time today. Last day in the office is Friday. I'll miss my colleagues but I won't miss the management and admin chores. On to full-time spacenerdery!

" Puisque je n'ai pas eu le Prix Nobel de la Paix, je vais envahir le Groenland, na ! " Mes petits cousins de 6 ans gèrent mieux la frustration que ce type. Et ils n'ont pas d'armées sous leur commandement...

The Carruthers mission, led by University of Illinois Urbana-Champaign's Lara Waldrop and managed by SSL, has arrived at an L1 orbit between the Earth and the Sun. Its 2-year science mission observing Earth's exosphere begins in March.

Very good news for NASA Science in the compromise 2026 funding bill released by Congress today:

Buongiorno dal Metop B! Intanto mi fa molto piacere vedere che i thread tecnici (USB-C e REC, che copio a breve qui) sono stati molto apprezzati quindi continuerò ogni tanto a farne. Nel frattempo, mezza Francia è stata imbiancata! Da noi nevica sull'Appennino Romagnolo e anche un po' in pianura.

Hoewel het nu zowat elke dag sneeuwt, daalt het aantal dagen (in Ukkel) met sneeuwval wel degelijk. Van winterseizoen tot winterseizoen zit er heel grote variatie op, maar als je wat uitmiddelt, dan valt de trend wel op. Data via frankdeboosere.be/klimaatukkel... #sneeuw #weer #klimaat

Grand news about the Nancy Grace Roman Telescope!!

Standing on its own four legs🦿🦿🦿🦿 @esa.int's reusable rocket demonstrator Themis is standing tall. Themis will demonstrate rocket stage recovery and reuse technologies and the first model arrived at the Esrange Space Center launch pad in Sweden 🇸🇪 over the summer.

NOAA-15 1800UTC pass One of the last days of NOAA APT transmissions, as NOAA-15 will be decommissioned this week 😢 That good ol' satellite has been transmitting for all my life, though, so I suppose it has earned its rest.

Ariane 6 has now been active for 1 year!

Internet Roadtrip is my favorite thing on the internet right now—it’s basically Twitch Plays Google Street View. They started in Boston, spent several weeks on a quest to cross the Canadian border, and are now exploring New Brunswick. neal.fun/internet-roa...

For your visual enjoyment. The last set was in the Finished Goods Warehouse in Decatur. These are at the Cape.

I could not have said this any better. Rockets are cool but what's the point of having them if we're not going to explore other worlds by using them? It's what we DO with these machines that matter. The funds ARE there,gang. Let's continue to be the driving force in space science.

An Andøya Space notice has revealed that the launch of the inaugural flight of the Isar Aerospace Spectrum rocket is set for 20 to 30 March. europeanspaceflight.com/inaugural-is...

I'm seeking a large sensor directional sensor that can track an object in solar orbit near Earth on the 137MHz VHF band. Anyone in the #radioastronomy community or satellite tracking community got a lead? THANKS!

My best satellite image yet! All the way from the Sahara to Iceland 😁 Meteor M2-4 LRPT ~14:00UTC

They say the lunar lander is communicating, but they believe they're not in the correct attitude. They are still working on getting the 1st images down so they can determine the exact orientation, but an internal measurement unit seems to suggest it's on its side again like IM-1.

C'est ce soir à 17h24, le deuxième décollage d'#Ariane6 vers l'orbite terrestre ! Un gros et double enjeu de souveraineté, à la fois pour le lanceur (malgré son problème de compétitivité) qui assure l'accès à l'orbite de l'Europe, et pour le satellite espion CSO-3 français et ses images du monde.

This is Marco Rubio explaining how the USA promised to defend Ukraine forever if they got rid of their nuclear arsenal left after the Soviet Union fell. This is why lil marco was sinking into the couch. He was hoping we wouldn’t find it…so don’t RT right now this very second.

Be sure to have a look at Venus in the near future when the clouds allow it! Nowadays, it is an obvious crescent, even with my simple telescope full of chromatic aberration.

The truth is disgustingly obvious and …. Ignored…

Enfin ! European car makers are also following this trend. It feels so uncomfortable!

Well, big news. I am planning to move the Space Library to a new home. And I need some help - in 35 years I've never asked for funding, donations or subscriptions for my Space Report, to keep it independent, but now I need to raise some additional funds. www.gofundme.com/f/fund-jonat...

Another fun thing at Saturn: its walnut shaped moon Iapetus! Not only is it a super fun word to say, but the moon sports an equatorial mountain range running most the way around and up to 10km high.

I love planetary atmospheric refraction 🥹

It has been quite the day, has it not?

Cassini took so many amazing pictures 🤩 Dione behind Saturn's rings, with Rhea in the foreground. Processed by @ugordan.bsky.social.

#OTD 14 January 2005, ESA’s #Huygens probe made history as it touched down on Titan, Saturn’s largest moon. This was humankind's first successful landing on a world in the outer Solar System. Relive those moments with this narrated video made with Huygens data 🔭👇 www.youtube.com/watch?v=svmG...

On Wednesday 15 January, 2025, the @esa.int #ESA_Gaia will cease science operations. This remarkable mission transformed astrophysics, galactic & Solar System science. Read more from Prof Michael Perryman essays: www.michaelperryman.co.uk/gaia-science...

Pas moins de 10 vols inauguraux de lanceurs sont attendus en Chine cette année, dont certains cruciaux dans l'avancée du New Space et de la réutilisation (Zhuque-3, Tianlong-3, Pallas, Hyperbola-3). L'année 2025 s'annonce intense en Chine. Petit guide 👇 www.futura-sciences.com/sciences/act...

10 years ago, no one knew what Pluto looked like. 95 years ago, no one knew Pluto existed. Now you can get a globe of it for Christmas. ❤️ Imagine what else is out there to find.

Blue Origin has officially received its launch license for the first flight of the New Glenn rocket. The vehicle is currently preparing for a static test of its 7 BE4 engines on launch complex 36.

Resurs-P No.5 has now launched, marking the 2000th launch of the R-7 family 😮

CRS-31 re-entry today around 11:32am central (18:32 UTC). This is presumably the last SpaceX Dragon to re-enter over land. Approximate luminosity indicated by line thickness.

Atlas, as seen by Cassini on June 7, 2005. Both the moon and the rings are behind the planet. Notice the refraction bending of the rings' appearance by the upper layers of Saturn's atmosphere.

I've been working on figuring out how PROBA-3 ticks as it could be a pretty interesting mission to monitor. The mission comprises of two satellites designed for prolonged autonomous operation. One is a coronagraph spacecraft and the other an occulter. 🧵⬇️

Extra Energia fact: during the CADB-Aerojet-MSFC joint test program an RD-0120 ran for 480s at 25% thrust! 86 (of 480) tabs on nozzle stiffener rings dev'd fractures; the nat freq of the stiffeners matched w/ freq of forced oscillations at 25% thrust and at 15-25x higher force than at 100% thrust.
