First specialized asteroid mission and NEARly forgotten one. And first landing on asteroid!
So it's time to change it. First image is Mathilde in enhanced colors from 450, 550 and 700 nm filters. Second is artificially colorised high resolution mosaic (116 m/pix).

Ah, interesting. Thanks. =)
Of curiosity, why were there no images taken (?) after landing? Camera not pointed at Eros? Eros would have been out of focus? -------------------- -- Hungry4info (Sirius_Alpha)

I believe the camera was under the spacecraft.

QUOTE (tedstryk @ Dec 21 2009, 09:59 PM)  I believe the camera was under the spacecraft. The camera definitly had to be or else the spacecraft wouldnt be able to image its last moment before landing. unless it was spining around on landing which it wasnt.  One thing that is weird is why didnt they try to contact NEAR or try to make it image the surface if possible after landing and if that image had anything in it it would be worth more than a 1000 words about the asteroid. The image would describe the composition and strangeness of its surface. -------------------- "Thats no moon... IT'S A TRAP!"

QUOTE (Antdoghalo @ Dec 21 2009, 10:20 PM) or try to make it image the surface if possible after landing and if that image had anything in it it would be worth more than a 1000 words about the asteroid. The attached diagram shows that the MSI (multi-spectral imager) was bore sighted with the other instruments 180 degrees away from the LVA (large velocity adjustment thruster). NEAR-SHOEMAKER was dropped gently onto the surface with the LVA pointing up. That would put the MSI into the surface or very close to it depending upon plowing of the surface during landing. I don't know what the focal length of the MSI was, but the lens would have been WAY tro close to the surface to take a focused image. And this quote about the landed attitude from a team member: "From what I've heard, the XGRS instrument is pointed down. We're on the tips of the arrays, with a 15 - 20 degree roll. The two bottom panels are splayed forward, with the two upper panels in their normal positions. The best guess is a 17 degree angle of the main body from horizontal. However, attempts to reconcile the DSAD data (they’re mounted on the solar array hinge arms) with the amount of power being generated have failed. We might be on a slope, the aft end may be on a rock, or the hinge mounts, arms and/or panels might be bent. "
