I can't load Greg's "where is Messenger" link.


Seems to be working now: http://messenger.jhuapl.edu/whereis/index.php

Perhaps they do site maintenance on Sundays.

Too bad MESSENGER probably won't be around in 2016 when Juno arrives at Jupiter to make it 9!


Ah, but May 2014 will have Rosetta orbiting Comet 67P/Churyumov-Gerasimenko (can we start calling it C-G now? smile.gif ), so if it made it to 2014, it would make operating spacecraft around 10 solar system objects!

Nope, and you have to say it fast five times every time you mention it.

Really wanted to get this pic to mark MESSENGER's arrival, so tonight I hiked up to the castle even with my knackered knee...!

Four days before MESSENGER starts photographing Mercury - Mercury seen from Kendal:

Nice shot!
It's good to get a wide-angle view (like yours) before getting the close-up (MESSENGER's).
P.S., if anyone hasn't seen Mercury in the evening sky - low in the west 30 minutes after sunset - do it now as Mercury is fading fast (from Earth's point of view).

Thanks smile.gif Even wider angle shot...

(Mercury's a bit hard to see - you need to enlarge the image by putting your cursor at the pic's top right to bring up an "enlarge" optionm then you'll see Mercury between the tower and tree. You might need to squint, but it's there.

Honest. laugh.gif

*Sigh*
That's wonderful!
My photos were taken from a high school football field's bleachers.
Your shot was worth the climb!

Everything seems to be going okay so far.

It's a 'teleconference' so any media only need to phone-in.

Plus anyone can listen in via the News Audio Stream.

IIRC, some of the first images will be of a previously unobserved region near the North Pole?

Well, not a 'great' question, but what is the expected resolution of the first images, and what other instruments will be acquiring data?

I am curious about the orbital period of the MESSENGER spacecraft. Is it exactly 12 hours? If so, how was it chosen?
