Assembly is underway to integrate Polaris, a rover for exploring lunar ice. The appended CAD illustrates the Polaris chassis with transparent carbon tubes to show internal structures. Mechanical assemblies add structure to the carbon fiber chassis tubes for mounting rocker arms and passive averaging mechanism.
Blurring an image on a computer is relatively straightforward. The entire image is stored in the computer's memory and a program is run on a processor to blur the pixels. The program typically takes a window of pixels and averages them. This averaged value is the new, blurred pixel.

Each of Polaris’ four wheels is driven by a Astrobotic-designed actuation stack consisting of a large brushless motor, harmonic drive, and numerous custom components. Some of the components for these assemblies arrived today, next week the remaining components will arrive allowing us to begin assembly.
A significant number of scouts have become astronauts or STEM majors. To further encourage this interest, Astrobotic journeyed to Boy Scout Camp Twin Echo in New Florence, Pennsylvania to enlighten scouts about the history and growing interest in space, educate about the Google Lunar X PRIZE and space commercialization, and inform about the technical and interesting aspects of Astrobotic.
If you are interested in Astrobotic presenting at your organization, feel free to contact us at firstname.lastname@example.org.
Since the beginning of March, Astrobotic has been hard at work fabricating the carbon fiber chassis for Polaris. It involved cutting and sanding foam molds, and applying epoxy, sealant, and release agent. This week the team pulled the final side beam out of oven, completing the chassis piece-set. The chassis measures 1.8 m by 1.4 m yet only weighs about 10 kg. In the coming weeks, we will be fabricating Polaris's wheels and assembling the drive chain and chassis.
