The number of joined units classifies the size of CubeSats and according to the CubeSat Design Specification are scalable along only one axis to fit the forms of 0.5U, 1U, 1.5U, 2U, or 3U. All the standard sizes of CubeSat have been built and launched, and represent the form factors for nearly all launched CubeSats as of 2015. [ 30 ]
SBUDNIC was launched to test Arduino Nano and other commercial off-the-shelf technology in space, using a simple, open-source design. [2]An ambitious project is the QB50, an international network of 50 CubeSats for multi-point by different universities and other teams, in-situ measurements in the lower thermosphere (90–350 km) and re-entry research.
A Sho't tank at the Oz 77 memorial, near the Valley of Tears, Golan Heights Destroyed Israeli Sho't Meteor. The Sho't tank served in the Six-Day War in 1967 and the Yom Kippur War in 1973; one of them (Sho't Kal Alef), belonging to the 188th Armored Brigade, was operated by Captain Zvika Greengold, an Israeli tank ace.
The Oerlikon SSG36 anti-tank rifle demonstrated, that it was possible to build a successful straight blowback rifle up to 20 mm caliber shooting at 750 m/s (2,500 ft/s) velocity. The SSG36 used a Becker principle of bolt head following the rebated rim cartridge base deep into the chamber. After firing, the case and the bolt could safely back ...
During the development of the Estonian satellite mission it was decided to make a 1U CubeSat. By standard 1 unit (1U) CubeSat base side length must be 100.0±0.1 millimeters and satellite height must be 113.5±0.1 mm. Mass is also set in CubeSat standard, the highest possible mass for 1U CubeSat is 1300 grams.
ESTCube-1 1U CubeSat. A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under 1,200 kg (2,600 lb). [1] While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass.
The shoebox-size satellite lifted off Saturday at 7:42 p.m. local time (3:42 a.m. ET) aboard a Rocket Lab Electron rocket from Rocket Lab’s launch complex in Mahia, New Zealand. The company ...
The Solothurn S18-1000 20 mm was a German anti-tank rifle designed and manufactured in Switzerland and used during the Second World War. It was a variant of the earlier S-18/100 with modifications for a higher muzzle velocity, as well as a larger cartridge size. The more powerful ammunition resulted in significant recoil, which was problematic ...
