Quote from: aero on 05/23/2021 04:12 pmI saw a string of Starlinks last night (~8:45 PM) passing from the southwest to the north east from San Diego (maybe 20 degrees elevation). I took a few still pics with my Pixel 3A telephone on "night sight" and I may post them if you want to see them. My phone could only capture 3 Starlinks per shot so the pics are not nearly as good as is customary here on NSF.What I'd like to know is, "When will the string next pass along the same (or nearly the same) trajectory?" Knowing that I can wait and watch for them.Heavevs-Above.com has a page specifically for that question. You can look up the Starlink satellites from a particular launch if thats what you want. Note that they disperse along the track pretty quickly. Since you say only three fit in one shot they are already somewhat spread out, but will get more so as time goes on. Being launched into an orbit higher than other Starlink trains, they might not fade as much as those from the usual, lower altitude launches.

We achieved another major milestone at Capella Space last week. On Friday, May 21, we released the first light image from the latest satellite we added to our SAR constellation, launched just 5 days earlier on the SpaceX Starlink 26 mission
Tyvak is seeking experiment authority to operate its Tyvak-0130 satellite in support of a Cooperative Research and Development Agreement (“CRADA”) entered into with the Lawrence Livermore National Laboratory (“LLNL”) for the purpose of advancing the development of compact telescopes for space-based sensing applications. LLNL developed a Monolithic Telescope (“MonoTele”) technology, which involves the fabrication of an optical sensor using a single monolithic fused silica slab. This approach allows the use of extremely tight tolerances for the optical prescription of the optic, leading to high performance in a compact package. This design approach also is very robust, as the alignment tolerances are held within the glass and not by external metering structures. An optical payload designed using this technology does not require in-orbit focusing or alignment, which greatly simplifies spacecraft design and favorably minimizes spacecraft size, weight and power.The Tyvak-0130 satellite includes two MonoTele sensors developed by LLNL, a threepiece bonded telescope designated “V3” and a single monolith “V4” design. The inclusion of the MonoTele sensors on the Tyvak-0130 satellite is intended to test the application of the sensors for use in commercial space-based earth observation, space situational awareness, and satellite navigation markets. Tyvak has already secured an earth sensing license from NOAA for the operation of these space-based sensors.
