Emily has a good summary of the effects of this on science observations for the next couple of days. In a word, minimal.

Rumors that Contact with new horizons has been lost again or was never regained. Unconfirmed

Still showing data downlink on Eyes. Not longer just a carrier either; nearly 1 kb/sec!

QUOTE (Steve5304 @ Jul 5 2015, 01:37 AM) Rumors that Contact with new horizons has been lost again or was never regained. Unconfirmed It's better to go by the official statement from the New Horizons team than some unfounded rumor. Based on the information received, the spacecraft not only responded to the anomaly but was able to do a lot of autonomous switching, including switching to the backup system (that's not a single switch), verifying that an antenna was pointing towards Earth and configuring its telemetry system and transmitter for the lower bit rate. This problem could range anywhere from a fault logic parameter that was too sensitive to a failure in one of the primary systems (which have backups) and anywhere in between. We, here, don't have the data to know what it is. We'll just have to have patience and wait to find out from the NH team. After all, there is nothing that any of us here can do about the anomaly but wait. In the meantime, there are July 3rd images that could use some magic... Andy |

Agreed. Eyes On The DSN has been clearly showing downlink for hours now so there is no need to spread obviously quite uninformed rumors from anonymous sources.

I assume the NH team declared a "spacecraft emergency" and therefore now has priority at all of the DSN ground sites, when NH is in line of site. Andy |

No idea, but I think that's standard procedure.

And that settles that! Going to sleep easy now, advise everyone else to do the same.

Thanks Alan for posting. We're checking in now in Europe and it's quite late in the US. Cheers to all the NH team.

Thanks for checking in at a VERY busy time for you & the team to talk to us, Alan.
For those who may be unfamiliar, Dr. Stern is the New Horizons Primary Investigator (PI): the boss. If he says something that's the last word on it, period. I'll also state that silly things like that rumor aren't suitable for this forum, especially if the PI feels it necessary to correct them personally during (of all things) a spacecraft anomaly recovery. Please keep this in mind at all times; they don't want or need that noise, they're more than busy enough already. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The silly rumours can be quite disconcerting. Thanks to Alan for being interested enough to clear the air for all us spectators.

I'm glad I came here to get things cleared up. Nasty rumors may not be worth the time and space here, but it's become national news.
[link] Big thanks to Dr. Stern for clearing it up, and to all of you guys, too. -------------------- - Matt
