27 August 1962 was launched the station “Mariner-2”, went on to study Venus. This unit was a complete copy of the “Mariner 1”, however, the first campaign to study the second planet of the solar system was marked by failure. The accident occurred right at the start.
With a weight about 200 kg space station was equipped with a range of scientific equipment to measure the magnetic field, infrared and microwave radiation, detection of high-energy particles, meteoric dust. After running the unit was close to Venus at a distance of 34 700 kilometers. With this cosmic structure was confirmed assumptions that the planet is an extremely hot atmosphere, and also proved the absence of magnetic field. Also, the “Mariner-2” measured the speed of rotation of the planet around its axis.
The connection with the station ended in early January 1963. On November 5, 1964 in space, was sent to another station “Mariner-3”. However, this apparatus was designed to study Mars.
Note that the first study of Venus began, Soviet scientists. Namely, on February 12, 1961 in space was launched “Venera-1”.

August 27, 2011, the company Razer has released its first “true gaming” laptop. The model is called Blade. In the firm did not hesitate to call the device the “world’s first true gaming laptop”. Indeed, the laptop had a few interesting features. In addition to improved performance, of course.
So, the laptop casing was made of aluminum alloy. The outside of the chassis got a soft-touch cover. First gaming laptop was equipped with interface Switchblade User Interface that is used to this day. It’s ten adaptive keys and an auxiliary display. Button responsible for the activation of certain commands in a particular game. The display works in two modes: in the first showed the related information in the game, if authority control was the mouse; in the second he played the role of a multitouch sensor.
Based on the 17-inch Razer Blade first generation lay the Central processor Intel Core i7 2640M (2.8 GHz) with 8 GB of RAM DDR3. The graphics answered “discrete” NVIDIA GeForce GT555M with 2 GB GDDR5. Storage played a hard disk of 320 GB with a spindle speed of 7200 rpm Sickly configuration for 2011. In this case, all the iron has been placed in a very thin body. The thickness of the device was only 2.2 cm, weight — 3 kg. These parameters are able to delight even today, although many manufacturers of gaming laptops has also learned to make very thin and light model. However, at the time of the announcement the price of the Razer Blade was neither more nor less than 2800 U.S. dollars.
