I have (at last!) added the "angular diameter" and other calculations to my realtime simulation at http://www.dmuller.net/rosetta

According to the Rosetta Real-Time Simulation, they've started the flip manouevre.

According to the Rosetta Real-Time Simulation, they've started the flip manouevre. Not yet ... the red box is the "next event" ... start of the flip maneuver is still some 4 hours away. EDIT: Will try to make it clearer in version 3 of the sim -------------------- |

Ahh okay. My mistake.
From the Rosetta Blog. Less than 330,000 km! http://webservices.esa.int/blog/post/5/1238 QUOTE Richard Moissl on the OSIRIS team just wrote: "We are closing in at a steady pace (less than 330,000km distance to the asteroid now) and the narrow angle camera is starting to resolve surface structures." -- Daniel

160.000 km and counting!
http://www.dmuller.net/ is a REALLY cool site! Will flyby image be live, or will they be released only after "18:19:53 Resume radio communications via high-gain antenna - Acquisition of TM signal (latest)" ? |

I'm guessing after they re-establish contact with Rosetta.
Maybe at "16:00:00 Resume Webcast - Media Event Life from ESA/ESOC - Science Team Present Images" -------------------- -- Hungry4info (Sirius_Alpha)

The first images will not be released until just after the World Cup Match is over; the schedule says 23:05 CEST but it could be later if the match runs into overtime.
Daniel: Your simulation is, as usual, terrific, but there's one thing about it that's a bit confusing -- all spacecraft events are reported as SCET but the Earth events are reported in Earth time. Since one way light time is 25 minutes there's a significant difference. So your countdown has the webcast starting after closest approach, when in fact it starts before closest approach ERT....not sure what to recommend as a fix though, because I like events being reported as SCET but it wouldn't make sense to convert Earth events to SCET. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Emily: You've described my problem quite well! The ultimate solution will be to offer two realtime simulations, one in SCET, the other in ERT. The problem is the data processing, in particular converting events from SCET into ERT without blowing up the database (or doing everything manually!) My target to have that sorted out is the MESSENGER Mercury Orbit Insertion. Unfortunately there is no quick fix, other than leaving out Earth-based events (which I usually do), however, in this case I wanted to draw attention that ESA has a webcast.
maschnitz: it's great that people find the website useful. The link from ESA has certainly yielded many referrals. On 10 July (my local time in Australia), I had 2,200 visits (usually between 40 to 100). -------------------- |

Perhaps as a short term solution, for the few events you report that are on Earth (like the webcast) , you could just include text indicating what OWLT is and how to correct...

Sounds like a feasible idea. Too late to implement for Rosetta @ Lutetia, traffic to the site is too high at the moment and I won't risk messing up the database now

A webcast has started.
http://webservices.esa.int/blog/post/5/1244 "Rosetta is a spacecraft. Lutetia is an asteroid. Rosetta will fly by Lutetia." kind of stuff. -------------------- -- Hungry4info (Sirius_Alpha)

LOL, of course the images will be presented only after I board my flight in Dallas...
