The Kosmos-3M (Russian: Космос-3М meaning "Cosmos", GRAU index 11K65M) was a Russian space launch vehicle, member of the Kosmos rocket family.It was a liquid-fueled two-stage launch vehicle, first launched in 1967 and with over 420 successful launches to its name.
A random orbit sander, with disks of various grit sizes. A random orbital sander (also known as a palm sander) is a hand-held power tool which sands in a random-orbit action. That is, in constant irregular overlapping circles. This technology was first commercially utilized in 1968 [citation needed] [1] by Rupes Tools.
The Kosmos-3M was a liquid-fueled two-stage launch vehicle, first launched in 1967 and with over 420 successful launches to its name. The Kosmos-3M used UDMH fuel and AK27I oxidizer (red fuming nitric acid) to lift roughly 1,400 kg (3,100 lb) of payload into orbit. It differed from the earlier Kosmos-3 in its finer control of the second-stage ...
Ceradyne was founded in 1967 [3] and in late 2004, the company added new product lines by acquiring ESK Ceramics of Kempten, Germany. [4]In addition to producing ceramic components for industrial processes such as silicon foundries and ceramic fuel pellets for nuclear reactors, Ceradyne researched and produced varieties of ballistic armour for both personnel and vehicles.

There are only a few sites capable of polishing the mirrors for these telescopes. SAGEM in France polished the four VLT mirrors, the two Gemini mirrors, and the 36 segments for GTC. [18] The Steward Observatory Mirror Lab cast and polished the two LBT mirrors, the two Magellan mirrors, the MMT replacement mirror, and the LSST primary/tertiary ...
Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.
