Dawn is now officially in orbit around (1) Ceres!

Congratulations, NASA. Nice images of crescent Ceres.

I thought it was time for a new thread, now that Dawn's in its first orbit. We can look forward to a couple more op navs, on April 10 and 14, and then RC3 later in the month. Use the previous thread for up to Op Nav 5; let's use this thread for Op Navs 6 and 7 and RC3 and then we'll split again once Dawn reaches its first survey orbit.

thanks emily!

i noticed in a prior thread that it said mapping starts in July. thats a bit of a misnomer as mapping starts in Survey Orbit in May (and one can count RC3 as a global map, at about 1.5 km resolution, which is comparable to much of Voyager at Saturn.) wows!

What should nonetheless be correct is that a new mapping phase starts in July, namely HAMO; and that this is still the month New Horizon zooms past Pluto. wink.gif

Also the time when the fireworks on 67P are expected to really start.

From http://www.nasa.gov/press/2015/march/nasa-...ly-enter-orbit/ :

QUOTE
NASA will host a media teleconference at 2 p.m. EST today [Friday] to discuss the historic arrival of the agency’s Dawn spacecraft at the dwarf planet Ceres. ... Participants in the teleconference will be:
- Jim Green, director, Planetary Science Division, NASA Headquarters, Washington
- Carol Raymond, Dawn mission deputy principal investigator, Jet Propulsion Laboratory, Pasadena, California
The teleconference will be streamed live on NASA’s website, at: http://www.nasa.gov/newsaudio


Does anyone know if a recording of this telecon exists? Normally, at the end of a NASA telecon they offer a number that you can call into to hear it again -- inexplicably, they only offer that number DURING the call itself. Also, JPL will sometimes take the audio and make a video out of it (synced with slides if there are any) and upload to the Ustream or Youtube account.

Or was there absolutely nothing of interest said during the telecon, just the usual recapping of what's happened?

Thanks!

Thanks but that's the PREVIEW briefing, that aired on NASA TV on Monday. I'm talking about the teleconference (media phone call) from Friday.

Searched for it on YouTube:

Edit: finally had a chance to listen to it - nothing new was said, really.

And Voyager 2 might break out into interstellar space at about the same time also. The values for the interstellar >70 MeV protons have been slowly climbing to the same value as for V2 - though if the current trend holds it might happen a few months later.

It must be an unusual sight. The narrow sickle of Ceres with constellation of Orion in background.

Thanks Peter,
just dipped outside for a look and there is Orion, laying in the west. Go Dawn.
