The latest rumour on NK has it that the low-gain omnidirectional antenna is not visible from the ground stations as the first fuel tank (the one that was supposed to be disposed of after the first burn) covers it. Which in turn means that they cannot reset the spacecraft and send orders (the directional antennas have really small field of view so chances of a signal being in the way are non-existent). If that is the case, is there any chance that they could get lucky and get a shot at the directional receivers or perhaps put enough power so that the craft could detect the input on the low-gain antenna?

Correct me If I'm wrong...
Where do we stand with how much time is specifically left before it's no longer possible to save the mission?What is the orbital decay rate vs how much propellant margin there is to still get out of LEO?
To all those talking nonsense about the communications system, everything installed on FG is the most reliable equipment there is, the most robust and trouble-free. The reason there is no telemetry is not because we aren't able to receive it, but because the SC is not outputting it.

It's very small as well, so it won't have too much drag on it. I think we've been hearing that orbital decay constraints give controllers a couple weeks before it re-enters naturally.
основная проблема состоит в том, что малонаправленные антенны МНА сейчас затенены сбрасываемым баком и управляющий сигнал для перезагрузки систем не проходит. Никто не предпологал, что придется работать в такой ситуации. Остронаправленная антенна ОНА сейчас в зачекованном положении. Для тех кто тут нес чушь про системы связи, все что установлено на АМС - самое надежное из того что есть, самое дубовое и безотказное. ТМИ нет, не потому что мы не можем ее получить, а потому что аппарат ее не выдает (по какой то причине), и сама по себе она не появится. Поздно вечером снова будут попытки передать управляющий сигнал. На этом все до завтрашнего рабочего дня. ПС старайтесь хотя бы не обижать тех людей, которые с вами инфой деляться. И не ведитесь на теории заговора. Нет в сми новой инфы, только из-за того что ее действительно НЕТ. И ни кто не хочет лишний раз светить свою фамилию сообщая неблагоприятные вести...
от чистого сердца стараемся, для всех сопереживающих. А для тех кто говорит что в Лавке ничего делать не умеют, приходите к нам на работу инженерами или в цеха. Молодой специалист 14000 оклад плюс премия. Ждем. И все забыли про Электро и Спектр. Первая АМС в России за 15 лет, вы только вдумайтесь! Памятник поставить всем инженерам, которые в ттаких условиях работают!
Crazy question time:Is there anyway the ISS can help with the receiving or transmission of mission data to PG?
Why not suggest TDRS, whose name has "data relay" in it?Dont mean to sound snarky, just pointing out gaps in the thought process.
