Hmmm.....two White Shirts and the TV guy by the tubes. I always get nervous when the White Shirts start hanging around wink.gif

Here are a couple more blow-ups of the big screen, this time in grayscale. The dark-line feature in the lower-right and the dark dot in the center are definitely being maintained...

11/12: As of 1:00 pm, geocentric distance between Itokawa and Hayabusa is 430 meters.

Those screen blow-ups are interesting, odave...

So here I am, two computer screens in front of me, a glass of wine strategically placed between them. On one I'm making a polar pan of Anatolia from Opportunity sol 72, on the other I have the Hayabusa blog up (with this site in another tab). Ahhh... life is sweet... or is it just that I don't have a life?

Watching the webcast is like watching the live coverage of the ISS. I've been constantly hitting refresh on the blog like every 10 seconds. My fingers are hurting.

Any idea when we were supposed to receive a signal from Minerva?

I just posted that Opportunity polar pan...

The latest images from Hayabusa are getting quite dramatic...

We must still be a couple of hours at least from the Minerva release, they only just cleared the 'big end' of Itokawa.

I suspect you may be correct on the image being for autonav, Odave.

Phil: Based on my personal experience, you're right on both counts. Life can truly be good, even when you don't have a life.

Itokawa's image captured at 12:47 pm JST. Due to the rotation, shadow part ON the right is appearing.

odave... I'm troubled by this... it's difficult for me to reconcile the images you are showing and the navigation camera images that are being posted. There is a time lag with those postings... I guess... but the latest images of deeply shadowed areas are not at all like the shots you are grabbing off the screen.

edited: looks like the time lag is bigger than I thought. Maybe there is no problem after all...

edited again... Hmmm... shadows on the screen come and go as people move around the room... are we just looking at a projector?

last edit: at this link:

http://www.isas.jaxa.jp/home/hayabusa-live...archive=2005-11

go to the bottom of the page... the screen seen closer up - it's a 3D trajectory diagram, not an image from the spacecraft.

200 meters now.



The shadow has cleared.

Edit: Just noticed..you can see Hayabusa's shadow on the right.

Yep... just look for the brightest point on the "ground" and there's your shadow... works in aeroplanes (occasionally) too.

For those still awake and anxiously waiting for more information, here's suzuka's live blog which provides more detail on the status of Hayabusa/Minerva (suzuka is a poster from space.com):

O'clock of 16 30 minute presently, already it is quick the ぶ, starting rise, it has gone away from the I To matte.

It is circumstance at the time of ミネルヴァ discharge.

This time it is quick the ぶ, in order automatically to start rise with the high-level 40m from the ground level, it was set. Discharge of the ミネルヴァ after the starting the rise, discharges perhaps with approximately the high-level approximately 200m.

From discharge it receives the signal from the ミネルヴァ 5 minutes later. After the discharging the ミネルヴァ verified that you have lived.

Because it became discharge from of the high-level 200m (distance of extent which is equal to length side radius of I To matte), whether or not it succeeds in landing, it is delicate. Climbing speed over ten cm/s, discharge speed of ミネルヴァ to cross direction about 5cm/s. Whether or not the speed vector which it synthesizes, exceeds the escape velocity of the I To matte, presently you do not understand yet. Whether or not it landed as for the verification of, of being after the tomorrow the possibility large. There is also a possibility of becoming the satellite of the I To matte.


So if I am reading this right, it was discharged from 200 meters? Wasn't the original plan to discharge it from just 17 meters? In any case, I hope they succeeded in the landing. *Fingers crossed*

No, life can't get much better. You could be sitting in front of a TV with a can of beer watching pro wresting. wink.gif

This is exciting.

I'm on dialup, so I don't even try live video, but my mental image of that control room is similar to what I recall from a Godzilla movie...
