The nucleus of comet Temple turns out to be very fragile

In the NASA presentation of the results of the Stardust spacecraft flyby of the nucleus of Comet Tempel, images were presented in which the results of the bombardment of the comet in July 2005 can be seen. My expressed conjecture about the pattern of the debris was not supported. In the high resolution images, which were not released to the internet before the press conference, the scientists were able to detect a small crater on the order of 150 km in diameter. During the time since the collision with the impactor, the edges of the crater appear indistinct and more smoothed out. Along with other changes in the outward appearance of the comet’s nucleus, we can say that it consists of very fragile material which, by the way, supports the current model of the structure of a comet nucleus.

The most detailed to date image of Comet Tempel, was taken in the flyby. Possible traces of the collision of the impactor can be seen as a bright stripe on the surface of the comet. The image is rotated 90 degrees counterclockwise compared to the 2005.

NASA specialists have begun receiving the 72 images planned for the flyby of the nucleus of Comet Tempel 1. On the left you can see the first of the received images. The image was taken from a distance of 2462 km from the comet’s nucleus. In several hours there will be a NASA press conference at which they will present the remaining images. Stay with us!

Stardust approaches its next target

January 18 and 19, the first pictures taken by the spacecraft Stardust of its mission to return to the nucleus of Comet Tempel 1 were received. The pictures were taken by the spacecraft’s navigation camera from a distance of 26.3 and 25.4 million km. In two weeks, February 14th, the spacecraft will pass 200 km from the nucleus of the comet with the goal of photographing the results of the bombardment in July of 2005 by another spacecraft, Deep Impact.

At the time of the flyby it is planned to take 72 detailed photographs of the surface of the comet and compare them with the pictures from 5.5 years ago. An analysis of the results of the crash of the impactor into the nucleus of the comet will allow us to better understand where and of what the comets of the Jupiter family formed, as well as the physical-mechanical properties of their surfaces.

The encounter of the spacecraft and comet will take place 337 million km from Earth.
