About the formula: 100mm/tan(0.527344 deg). What is 100 mm (milimiter)? Is the distance of what are you saying.

Let suppose that a point of interest in the picture: a stone:   Left navcam: 580 pixels (GIMP tool measurement) and the Right navcam: 590 pixels:

According to the Paralalx calculator: object distance: 8.92 m, one-pixel error: 0.037 m
object dimension: 0.2 cm.

According to the formule:
The separation distance is: 590-580= 10 pixels.

@ angle is:  (10 pixels*45 degree)/1024 pixels
@ = 0.439453

distance = "opposite side, not known, how to obtain it?" x tan(0.439453). I guess that the opposite side must be always of 100 meters?

P.D.jamescanvin has talked about the measurement of distances  with parallax calculator in the topic: Haskin Ridge, how did he measured it? See at the post

Welcome back!

Are you going to launch www.mannedspainflight.com for your vacation pix?

With the exception of the dust gust on sol 675 noted by Alan in the post above, there hasn't been much dust devil activity showing up in the haz/nav/pancam imagery (although there haven't been many dust devil movies attempted in recently sols either).

Second, you must convert the feature height in the image from pixels to angular size. Pancam pics have 16.8º fov, so given a height of 60 pixels (that is what I get from your post) it corresponds to aprox. 0.984º.

Quite unsuitable comments, IMHO.  Mars Express has been a fantastic mission and made lots of major discoveries which have led to an impressive portfolio of publications, with many more to come.

I think some of those are empties

I would be in favour to perfect the design based on the lessons learnt, build a series of Hayabusas, and start visiting all the NEOs one by one.

Congratulations to the Japanese on an apparently successful mission - hopefully a sample will be returned home successfully. And thanks to everyone here from Japan who has made it easier to follow this exciting mission over the past several hours. It seems I can go to sleep now .

When you put the foam issue as you just did, it doesn't make any since. However, the payload involved isn't simply unmanned hardware, but humans. Also, NASA knows that funding for the Shuttle will most likely be nonexistent if another accident occurs.

As much as I love manned space flight and support the Vision for Space Exploration, I absolutely DESPISE the notion of taking funding from unmanned spaceflight to fund manned spaceflight. An effective space program has to be balanced.

One instance that has recently burned me is the Dawn mission to 1 Ceres and 4 Vesta. Did you know that JPL has been told to stand down with this mission? The solution to NASA's funding shortfalls isn't jiggling the books, but simply receiving more funding from Congress. Unfortunately, there is nothing simple about that.

...Um, wait,,,
does it mean, they did not close the first sample capsule, because they managed to land at the same place? Does they also have one empty capsule yet?

Volks, I guess we might need some Lipos again in the coming few days

Yes, I will give you yet another "Zabuton 5 Mai" for the Lipo-D gag team! ;-)

In fact, no. There is nothing on board that can verify that. They assume material to be collected, if the bullet was fired and the probe's attitude was properly oriented. So I guess what they will verify next is the detailed attitude history of the probe. I am not sure if there is any sensor on the sampler horn's movement.

EDIT: (clarification) if memory serves, the sampler horn simply detects the contact and the bullet gets fired.

Matsuura's blog says the sampler device functioned properly and the subsequent ascent phase seemed just fine as well. This is probably as good confirmation as we can get. I guess we can celebrate for their achievement.
