R.I.P., Walter Koenig. 😢 Forever remembered for his iconic roles as Pavel Chekov in Star Trek and Alfred Bester in Babylon 5

Then I'm the ENEMY! The term "super intelligence" is neither more accurate nor is it highly accepted. Only Trump's sycophants use this term. But people knowledgable and working in this field use the established "artificial intelligence". This is not 1984, we do not use newspeak! Nor Trumpspeak!

SpaceX has for the 1st time launched Starship to orbit. Ship-41 & Booster-21 lost 1 Raptor engine each on ascend. 26 Starlink v3 sats were deployed. Then successful deorbit burn. Booster made water landing off coast of Texas & Ship near Hawaii. Congratulations to SpaceX.

Top Pentagon officials confirm the US operates “on-orbit space control weapons” (definition unclear) to defend against attacks - the clearest admission yet. China & Russia slam it as escalation. We have not yet identified the satellites related to this although there are suspects.

A Falcon Heavy has launched NASA's Roman Space Telescope to the L2 point. It's a space telescope with a 2.4m primary mirror inherited from a defunct spy satellite program. It'll in IR survey vast regions of the Universe, probe dark energy & search for exoplanets. space.skyrocket.de/doc_sdat/wfi...

@SpaceX announced that today’s Starlink launch (Group 10-49) was the last planned Falcon 9 Starlink mission from Cape Canaveral. Future East Coast Starlink launches will use Starship, while Falcon 9 continues launching Starlinks from Vandenberg.

NASA and Katalyst have abandoned plans to boost the aging Neil Gehrels Swift Observatory after an attitude-control issue with the LINK servicer. LINK will still attempt rendezvous and proximity operations, gathering valuable data for future in-space servicing missions.

Chinese company LandSpace's 2nd flight of their Zhuque-3 orbital rocket performed a successful propulsive landing of stage 1. Stage 2 apparently reached orbit. The payload was likely a mass model.

There is a YouTube channel impersonating Gunter’s Space Page. I have NO connection to it & have reported it. Do not subscribe, engage or trust any accounts claiming to be me or the site that are not linked from space.skyrocket.de or my official accounts. Report it if you see it.

Reportedly SpaceX is turning away customers for dedicated Falcon 9 launches beyond 2028 & has stopped accepting new F9 rideshare reservations. Also halting production of sm expendable hardware (inc. upperstages), signaling a major shift to not yet operational Starship (Bloomberg).

Mixed result for 3rd flight of @BlueOrigin's New Glenn rocket: Reflown stage 1 successfully launched & landed. Stage 2 underperformed & left @AST_SpaceMobile's Bluebird-7 sat in off-nominal orbit. Final orbital elements not yet released, but I'm not optimistic. space.skyrocket.de/doc_lau/new-...

Yesterday China successfully conducted the maiden flight of the Lijian-2 (Kinetica-2) liquid fueled launch vehicle. It carried three satellites, among them the prototype of the Qingzhou transporter to be used to supply the Chinese Space Station. space.skyrocket.de/doc_lau/liji...

space.skyrocket.deLijian-2 (Kinetica-2)Lijian-2 or Kinetica-2 is a Chinese liquid-fueled medium launch vehicle developed by CAS Space, a rocket manufacturer affiliated with the Chinese Academy of Sciences.

Sad to report the passing of Mike Melvill, pilot of the 1st commercial suborbital spaceflight. He flew 1st SpaceShipOne mission above the Kármán line & with SS1 spinning I didn’t expect him to return alive. He stayed calm, returned safely & flew a 2nd time. www.youtube.com/watch?v=gl3Y...

Firefly Alpha successfully returned to flight. The last flight of the Block 1 version tested systems for Block 2 and put a Lockheed Martin Technology Test payload (possibly similar to the one lost in the last launch failure) in orbit. space.skyrocket.de/doc_lau/fire...

Space One's KAIROS small solid fueled launch vehicle has launched for the 3rd time from Spaceport Kii and again failed to reach orbit. About 1 min into the flight an energetic event was observed. 5 small satellites were lost. space.skyrocket.de/doc_lau/kair...

And here are the launch statistics for 2025 by launch vehicle families: Note: * includes the marginally suborbital Starship launches * includes Iranian Zoljanah launch, which is unclear, if it was orbital attempt

As every year, here are the launch statistics for 2025 by country. Note: * includes the marginally suborbital Starship launches * includes Iranian Zoljanah launch, which is unclear, if it was orbital attempt * RocketLab launches are listed as New Zealand / USA

Wow - the Musk-Trump-bromance turns into a full-bloom divorce battle. Collateral damage may be crewed spaceflight, as Musk threatens to decommission the Dragon crewed spacecraft. I did not see this escalating so fast...

This article confirms that the USA are already testing satellites to track aircraft as a replacement for AWACS. Question is which are the satellites? Likely not the NRO or SDA missions. Unlikely also GEO sats and small sats. (1/2) aviationweek.com/defense/airc...

aviationweek.comRise Of Space-Based Aircraft Tracking Spells Threat To USAF E-7As | Aviation Week NetworkA top U.S. military official confirmed that satellites are demonstrating aircraft tracking as the E-7A program faces a cancellation threat from the Pentagon.

"Trump says Palestinians should leave Gaza permanently and US will ‘take over’ strip" What the FCK is wrong with this guy? (Question is rhetorical!) His ideas of diplomacy are equivalent to using a chainsaw for brain surgery! We, the world, are so screwed! edition.cnn.com/2025/02/04/p...

edition.cnn.comTrump says Palestinians should leave Gaza permanently and US will ‘take over’ strip | CNN PoliticsPresident Donald Trump said Tuesday that the US “will take over” the Gaza Strip, after saying earlier that he doesn’t think there is a permanent future for Palestinians in Gaza.

Dear crowd, does anyone know if the very first RocketLab Electron rocket ('It's a test') carried already the Kick Stage? IIRC, the Kick Stage was only announced on the 2nd flight. Currently I have listed the 1st flight in my database as having no kick stage, but i still lack a solid confirmation.

The Iranian Islamic Revolutionary Guard Corps has launched the Suraya satellite (purpose unknow, possibly communications) on the 1st successful orbital flight of the Qaem-100 rocket, reaching a 750 km orbit. Launch site was the Shahroud Missile Test Site. space.skyrocket.de/doc_lau/qaem...

space.skyrocket.deQaem-100Qaem-100 (also transcribed Ghaem-100) is a new Iranian space launcher operated by the Islamic Revolutionary Guard Corps Aerospace force. It based on the Rafe' solid rocket motor.

Astrobotics Peregrine lunar lander has suffered shortly after launch a propulsion failure which led to a critical loss of propellants. I think, this likely rules out a lunar landing. :-( But perhaps some engineering data can be gathered.

@ulalaunch Vulcan rocket has successfully conducted its maiden flight. It is powered by 2 @blueorigin built BE-4 engines fueled with LNG/LOX. 2 GEM-63XL solid fuel boosters provided additional thrust. A dual engine Centaur-5 was the upper stage. space.skyrocket.de/doc_lau/vulc...

space.skyrocket.deVulcanThe Vulcan launch system, provisionally called NGLS (NGLS), is a replacement under development by ULA (United Launch Alliance) to replace both the Atlas-5 and Delta-4 families.
