Starlink-4
17.02.2020 состоялся пуск Starlink-4. Запущено 60 спутников Starlink v1.0 массой 260 кг каждый, всего 15600 кг плюс удерживающая система. Четвертый пуск для ступени 1056. Ступень приводнилась рядом с ASDS и затонула. Обе половинки обтекателя повреждены. В отличие от предыдущих пусков было только одно включение второй ступени. Еще одно отличие в том, что вторая ступень осталась на орбите, а не была сведена как раньше. Полезная нагрузка была выведена на эллиптическую орбиту высотой примерно 212 х 386 км и наклонением 53 градуса.

CelesTrak has TLEs for 64 more objects (60 satellites & 4 spacers) from the Starlink-5 launch of Feb 17. We already had the TLE for the FALCON 9 R/B. pic.twitter.com/UM3KSLuwcJ

UPD Неудачная посадка первой ступени произошла из неверных данных о ветре.
At the CRS-20 prelaunch briefing, SpaceX’s Hans Koenigsmann said the failed booster landing last month was because the booster decided to divert; winds it encountered were not those that were predicted by models.

Recent missed landing (at sea) was due to incorrect wind data. If this (land) landing fails, it will most likely be for a different reason.

On the last one? Yes. The Upper Level Winds were far stronger than predictions. Blew booster too far away from drone ship. Not enough fuel to safely correct and land, so logic aborted to soft landing in water.
