The Agena Target Vehicle (/ ə ˈ dʒ iː n ə /; ATV), also known as Gemini-Agena Target Vehicle (GATV), was an uncrewed spacecraft used by NASA during its Gemini program to develop and practice orbital space rendezvous and docking techniques, and to perform large orbital changes, in preparation for the Apollo program lunar missions.

The first Agena-D launch was of KH-4 #7 on June 28, 1963, and a total of 269 Agena-Ds were launched. The Agena-D was used to launch KH-7 GAMBIT and KH-8 Gambit 3 reconnaissance satellites, three Mariner probes to Venus and the two Mariner space probes to Mars. Thor-Agena flew for the last time in 1972 when it launched a KH-4B satellite.
Tele Vue once manufactured a 5" refracting telescope named the MPT, the Multi-Purpose Telescope. It had a fast f/4 ratio, and had an adjustable diaphragm that ranged from f/4 to f/20. Only a small number were made, with the last being kept by Televue to use as a final optical quality control for all eyepieces they make.
(Reuters) - Ukraine possesses a laser weapon capable of shooting down airborne targets at an altitude of more than 2 kilometres (1.2 miles), the country's drone forces commander said on Monday.
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
The safety/selector lever is located on the right hand side and allows for semi-automatic single shots and fully automatic fire at the rate of 800 rounds per minute. The effective range of the PP-91 is between 50-100m. The weapon uses a diopter sight and allows for the use of a laser sight and a suppressor.
An electrolaser is a type of electroshock weapon that is also a directed-energy weapon.It uses lasers to form an electrically conductive laser-induced plasma channel (LIPC). A fraction of a second later, a powerful electric current is sent down this plasma channel and delivered to the target, thus functioning overall as a large-scale, high energy, long-distance version of the Taser ...
MILES systems used a laser module which was mounted to the barrel of a real weapon, a blank-firing adaptor for the weapon, and an integrated receiver consisting of sensors on the helmet and load-bearing vests of the soldiers. When a blank shot was fired by a weapon, it caused the laser to fire a coded burst in the direction that the weapon was ...
