I guess in the category of 'turn back to go somewhere' - the traverse of the northern rim of Victoria, only to enter at the very point we arrived must count smile.gif But there was a very good reason for that.

I can well understand why we're going to have a look. Not only does it look different to all the surrounding rock - it's also, I'd guess, the single largest rock not in a crater that Opportunity has ever seen.

Two points - one is the "Friend or Foe" nature of of Jupiter- google that exact phrase for the research, it's very interesting.

Secondly - twice I've seen people cite Comet impact rates.

Who says this is a comet? Could have been an asteroid. If it's one 2km Comet / 250yrs, then what does the statistical distribution tell us for, say, 100m sized objects? 10x more frequent? 100x?

Whoops

I ended up on the schedule smile.gif Something of a call to arms for the Amsat community to do the outreach that European scientists and STFC (H1'09 outreach funding cut by 50% for science in society projects) refuses to.

I'm wondering if the fact that Hubble is still in a recomissioning phase means that maybe, quick turnaround response for an orbit or two won't be too hard. I hope Damian Peach has had a look at it smile.gif

Do you think we could expect any greater resolution, maybe through the lroc image browser?


No. These thumbnails are at full resolution. We have to wait for the spacecraft to get into its final orbit before we go from these 1.2-ish m/pixel images to 50cm/pixel.

I was expecting a bit better. You can see the seismometer's western solar array just about. It's not map-projected, and calibration hasn't kicked in to fix that interlacing-look to the pictures.

MUCH better is to come - that's for sure.

This is roughly with the same illumination.

Oh - ok - you were counting ALL the pixels. Anyway - I started a new LRO thread for Apollo sites - we'll need it in about an hour or two hopefully smile.gif

Thought this deserved a new thread- we can't talk about EVERY LRO target in the one thread smile.gif

I made a mistake in this one - I didn't include the thruster plume guards. My MER/MPF simulation for HiRISE seemed to come out about right - so fingers crossed that this will be there or there abouts as well. Still in a comissioning phase, something of a slant angle - I'd expect approx 1.5m/pixel if it's at the 120km figure mentioned earlier.

But assuming 1.2 meter/pixel at the 120km altitude, the LM Descent Stage and its shadow should be defined by no less than 70 pixels.


The LEM is approx 4.5 metres across. At 1.2m/pixel - that's 3-4 pixels across, a total of perhaps 16 pixels of LEM.

Assuming a height of 4 meters ( which is generous) - and illumination at 10 degrees - the shadow will be another 17 or so pixels long.

I got one ISS pass. One STS scrub, no STS/ET flyover, SpaceX webcase gave no hint of actually starting, second ISS flyover was clouded out. So I went to bed.

VERY pleased for SpaceX
