Object 69094 (2025-135BX) based on TLE analysis appears to have come off W-4. It is probably too early to conclude it is the reentry vehicle, with a failed deorbit burn, but I look forward to an update from @VardaSpace.

Planet@planet·
First light imagery from our latest Pelican launch is here! 📸 Just days after launching three new Pelicans, we received high-resolution first light captures from each spacecraft, including the @Forsvarsmakten's first ever sovereign satellite. Check out these diverse landscapes from around the world. 🛰️🌎 investors.planet.com/news/news-deta…

Will Townsend@WillTownTech·
A small group of industry analysts including myself were pre-briefed on this very unconventional joint venture between @ATT, @TMobile and @Verizon. Eliminating dead zones is a noble endeavor to bridge the digital divide and to support first responders. I also like the potential to accelerate the deployment and scale of non-terrestrial networks utilizing low earth orbit satellite connectivity. However, I also view this alliance as a defensive move to mitigate the impact of any NTN service provider that might wish to more directly compete with mobile network operators. It's yet another interesting development in the race to space connectivity 🚀🛰️ ⬇️

Unclear what is happening with the @VardaSpace W-4 reentry. The W-4 spacecraft made a manuever on May 10 to lower orbit from 284 x 835 km to 162 x 820 km. At the same time a new object, catalog 69094, was found in a 157 x 735 km orbit

e-GEOS@e_geos·
🛰️ e-GEOS, part of @LDO_Space, has successfully completed the validation of the Automatic Identification System (AIS) aboard the Sentinel-1D satellite of @CopernicusEU. The activity contributed to the satellite’s In-Orbit Commissioning phase following last November’s launch. 🌍 To validate the AIS payload performance, e-GEOS analysed over 60 Sentinel-1D radar images across six key maritime regions worldwide. The analysis leveraged the e-GEOS proprietary SEonSE solution to correlate vessels detected in the images with the AIS data. 📸 In the following image, is reported one of the Sentinel-1D data used for the validation, acquired on 18th January 2026 over the Strait of Gibraltar.

Space42
Space42@space42ai·
Space42 and Skylo Technologies have announced a strategic partnership to deliver Direct-to-Device (D2D) connectivity through Thuraya-4, reaching places that previously had limited or no coverage. A bi-directional, real-time voice call was demonstrated over Thuraya-4 using a device with no modified SIM or changes to operator core infrastructure. For carriers, this is an extension of their existing network architecture. For end users, it means far reaching seamless connectivity. Commercial deployment will begin across Thuraya-4's coverage footprint. Read the full announcement at the link below:  space42.ai/en/press-relea… @SkyloTech @ThurayaTelecom #NTN #DirectToDevice #Connectivity #SpaceTech
