Russia has commissioned a new wintering complex at the Vostok station in Antarctica. The complex was built on the site of the legendary Vostok station in Antarctica, which was created in 1957, its deterioration reached 97%. This is the first modern building built at the Antarctic pole. Now polar explorers at the station are conducting important research - studying solar activity, studying cosmic phenomena and climate change. The new wintering complex consists of five blocks with an area of about 3 thousand square meters. It is designed to accommodate 15 people during the winter period and 35 people during the seasonal period. The construction of the Vostok complex was not an easy task. The Vostok complex, consisting of 133 modules, as well as fuel and equipment, began to be unloaded in Tala Bay near the Russian Progress station. From there the complex was moved to the Vostok station by sleigh-caterpillar trips. The transfer of modules and installation of the complex took two years; it began in January 2022 and ended in January 2024. The station stands on 36 supports 3 meters high, which will allow it to remain free of snow for many years.

Footage of the production of Russian Alazan missiles designed to combat hail. The missiles are produced by the Cheboksary Production Association named after. IN AND. Chapaeva. The Alazan-8M and Alazan-9 missiles are currently being produced.
The Alazan-9 anti-hail missile differs from the previous Alazan-6 in improved performance, despite its smaller caliber - 60 mm instead of 82 mm - its effectiveness is not reduced. In the new generation Alazan-9 missiles, the performance of the silver iodide reagent is increased by 2.5-3 times, and the cost, due to the smaller caliber, is reduced. How does this rocket work? An anti-hail rocket with a solid propellant engine, equipped with an active smoke bomb and spraying an aerosol of silver iodide. On particles of silver iodide, crystallization nuclei are formed, on which hailstone nuclei are formed. After which they fall to the ground in the form of rain or small, harmless hail. The missiles are capable of hitting hail clouds at a distance of up to 10 kilometers and at altitudes of more than 8 kilometers and are equipped with a self-destruction system. The use of anti-hail missiles makes it possible to reduce crop losses from hail in the southern regions of Russia by 70-90%. Previously, missiles were used in combat operations in the Caucasus and Transnistria.

Autonomous unmanned cleaning robots "Pixel" began to be used in cleaning several areas of Moscow on an ongoing basis. The Russian cleaning robot was developed by Avtonomika.” Pixel robots are equipped with lidar, radar, sensors and machine vision to move safely and can operate year-round in any weather. The robot is equipped with interchangeable attachments to perform various tasks, removing snow in winter, and mopping and sweeping paths in summer. When the robot encounters an obstacle in its path, it recognizes it and bypasses or allows the person to pass. Robots will not be able to replace wipers, but they will reduce their number. The robot's electric battery provides 16 hours of continuous operation and allows it to reach speeds of up to 10 km/h, and when cleaning up to 5 km/h. Having completed the task, the robot itself returns to the base. The developer plans to begin mass production of robots in 2024. After this, in Moscow it will be possible to “introduce unmanned vehicles into the city economy.”
Moscow enthusiasts showed a prototype of the Tikhon unmanned control system, designed for converting cars into drones. At first glance, against the backdrop of modern developments, the design looks archaic, but the advantages of this complex are that it can quickly be equipped with any car, without altering its design. Currently, the Tikhon unmanned control system consists of a twelve-kilogram suitcase and a control panel, but the developers plan to reduce the weight to 6 kilograms. According to the developers, this complex can be quickly installed on any equipment, including military equipment, and turned into an unmanned vehicle. According to them, all components are made in Russia.
At the Novocherkassk Electric Locomotive Plant of Transmashholding, the first Russian hybrid electric locomotive EMKA2 was manufactured for customers. The EMKA2 electric locomotive is capable of operating from a contact network or from an on-board energy storage device. The EMKA2 electric locomotive is designed for operation in depots and passenger terminals of large stations, where for environmental reasons the use of diesel engines is undesirable. The EMKA2 electric locomotive can be recharged in two ways - from the contact network through a standard 3 kW pantograph, or from an external charger. The energy in the electric locomotive's storage unit is sufficient to propel a train weighing up to 2 thousand tons over a distance of up to 14 km. Without a train, an electric locomotive can travel up to 100 km. Using an electric locomotive instead of a shunting diesel locomotive allows you to save up to 70-80% of fuel and lubricants and reduce current operating costs by 40-60%. The operating speed of the electric locomotive is 90 km/h, weight is 92 tons.

Russia has resumed its flight testing program for the new Il-114-300 passenger aircraft, which is expected to replace the An-24 on local airlines. The second experimental aircraft is a new version of the Il-114-300, assembled at the facilities of the Lukhovitsky Aviation Plant; the first aircraft was created on the basis of the Il-114-100 produced in Tashkent. The aircraft is designed for operation in normal and difficult climatic conditions. It can operate autonomously from relatively small airfields, both concrete and unpaved. Its maximum capacity is 68 passengers. The aircraft consists entirely of Russian components and is equipped with a TV7-117ST-01 engine, which has undergone a series of modifications. The engine has increased power during takeoff and is superior in technical characteristics to foreign analogues. The new AB112-114 propeller also has an increased thrust of 4 tons. Also, the new Il-114-300 has improved flight performance, increased the use of composite materials, installed a new digital flight navigation system, improved almost all the main systems, and special attention was paid to improving the ergonomics of the cockpit. The first flight of the Il-114-300 lasted 40 minutes, took place at altitudes of up to 900 meters and at speeds of up to 230 km/h.
Laser deforestation was shown in Russia. Specialists from the Troitsk Institute of Innovation and Thermonuclear Research tested a mobile laser complex produced by Rosatom. The laser was used to cut down forests, mainly the tops of trees, to speed up the laying of power lines. Using a laser complex, it was possible to cut a tree trunk 200 mm thick in six minutes; by simulating a laser beam, this time can be halved. The laser installation has no analogues in Russia and is capable of cutting even metal structures whose thickness reaches 260 mm, at a distance of no more than 300 meters. Previously, a sunken ship located 50 meters from the shore was cut with a laser on Sakhalin. There are no technical details; the laser complex can be installed on an all-terrain vehicle or other vehicle.
On April 11, the first Russian heavy launch vehicle Angara-A5 launched from the Vostochny cosmodrome in the Amur region. The rocket is equipped with an Orion upper stage and carries a test payload. The Angara family of rockets should replace the Proton-M launch vehicles. The Proton rocket has been in operation since the mid-1960s. The Angara-A5 rocket is the first heavy rocket of this type, developed in Russia after the collapse of the USSR. "Angara-A5" is an environmentally friendly rocket, its fuel does not contain toxic elements, unlike the "Proton" rocket, it uses kerosene and an oxidizer - liquid oxygen. Now there are three modifications of the Angara rocket, details are on the screen. The Angara-A5V rocket will be capable of launching a payload weighing up to 37.5 tons into orbit. With the help of Angara-A5 rockets, it is planned to launch automatic spacecraft and modules of the promising Russian orbital station into low-Earth orbit.
