Great movie, Roman! What an odd-looking little beast. Markedly different from the regular 'battered potato' look of the smaller asteroids, though we're a long way still from seeing enough of them to say what's 'normal' and what's not in that regard. You just contradicted yourself... |

No, and it was a bit of an off-the-cuff answer, but barring some additional information from the project it's all we have to go on, and it's not implausible given what details of the design we do know. For example, some types of Q-Tech oscillators really do draw 40 mA just for the oscillator, and then for a complete clock there has to be a counter and maybe some other stuff -- the fault protection paper references a "mission clock FPGA". I also don't fully understand how the scheduling of transmission and reception periods happens if the mission clock is lost. This seemed to introduce a lot of complexity into the attempted recovery process for Spirit. Presumably without the mission clock there's no way for the rover to figure when 11 LST is (in theory it could do with from solar power production but that would vary a lot based on tau, tilt, dust on the panels, etc.); AFAIK this scenario isn't described in the fault protection paper. The rover transmits roughly around midday on Mars, so the orbiters listen then. Once the signal is received they can send commands to the rover, which listens periodically, eventually getting back into sync with Earth. |

New press conference held yesterday. https://www.youtube.com/watch?v=S9nw3bli_Io&t=33s Presentation in Japanese, lot of veryu interesting info! (Probably English version is coming soon) http://fanfun.jaxa.jp/jaxatv/files/20180614_hayabusa2.pdf Google Translate seems to do a good job translating each slide. One slide says the image of the asteroid is now 10 pixels across, was 3. |

Are the solar panels able to raise up? I say this when MER traveled thru the space, the solar panels was inside in compact mode before it landed. During the process of closing (raising) and opening (lowering) solar panels might shake due to the motor vibration or also due to the slope, some dust will slip down. The wind blows the panels clean from time to time. |

TCM1 was completed 5/22 (yeah!). Can't provide much more data than in the news release but the S/C performance was great and we hit the desired DV well within 1 sigma. Very healthy spacecraft and now we are on a path to Mars! Lots to do in the coming months, but so far a really smooth cruise! Good to hear. |

Shouldn't the title of the topic be changed to "...attempted Schiaparelli landing" seeing as it was not successful ? |
