Roscosmos:
The Lavochkin Science and Production Association (part of Roskosmos State Corporation) continues to develop spacecraft for the world's first high-elliptical hydrometeorological space system, the Arktika-M.
The company completed comprehensive electrical and radio tests of Arktika-M satellite No.2. On the night of June 21 it was sent to the Rocket and Space Industry Research and Test Center (a part of Roscosmos) for testing in a vacuum chamber, which is scheduled for completion in July 2023.
After that the spacecraft will be returned to NPO Lavochkin for further ground checks.
The launch of the Arktika-M satellite № 2 is scheduled for the end of 2023.
The first Arktika-M spacecraft, which was put into orbit in February 2021, is unique in the global orbital constellation of remote sensing of the Earth for meteorological purposes. It observes the entire northern polar cap - the so-called "weather kitchen" - from space. No other country in the world has such capabilities.
In May 2023 Roscosmos and NPO Lavochkin signed a state contract to upgrade the Arktika-M system to increase its orbital constellation to four spacecraft, which will make it possible to halve the frequency of imaging the polar region and make observations of the required area from different angles, as well as detail super short-term weather forecasts, increase the speed of detection and monitoring of dangerous natural phenomena and emergency situations and increase the accuracy of cloud detection over snow and ice cover

Roscosmos:
The Arktika-M hydrometeorological spacecraft No. 2 returned to the Lavochkin Research and Production Association, which for three weeks underwent comprehensive electrical tests in the thermal vacuum chamber of the Rocket and Space Industry Research and Test Center (part of Roscosmos State Corporation).
The purpose of the tests was to confirm the performance of onboard systems in vacuum during three thermocycles, when the levels of cyclic changes in the allowable temperatures of the instrument landing sites vary from close to the maximum value to close to the minimum value. These tests are one of the most important stages of acceptance tests, upon completion of which a decision is made on the suitability of the satellite for its intended use.
The results of the tests are positive and the performance of the spacecraft systems under conditions close to normal operation has been confirmed. The Arktika-M satellite No. 2 will continue the ground experimental testing cycle at the development enterprise.
The Arktika-M spacecraft were designed by the Lavochkin NPO on a modular principle, are based on the unified Navigator platform and have virtually identical target equipment to the Elektro-L satellite. The main difference in the operation of the satellites is the types of orbits on which the target tasks are solved: "Elektro-L conducts regular (with 15-30 minutes periodicity) imaging of low and middle latitudes of the Earth from geostationary orbit, and Arktika-M conducts similar imaging of the Arctic region and adjacent territories above 60° N latitude, being in the area of apogee of highly elliptical orbit of "Molniya" type. Taking into account the peculiarities of the operational orbit, Arktika-M has higher requirements for radiation protection of the hardware and increased area of solar batteries compared to Elektro-L.
The first Arktika-M spacecraft was launched into the target orbit in February 2021, and the second satellite is scheduled for launch in late 2023.
Two Arktika-M spacecraft as part of the highly elliptical hydrometeorological space system of the same name will provide round-the-clock all-weather monitoring of the Earth's surface and the seas of the Arctic Ocean.

Roscosmos:
On November 13, the Arktika-M spacecraft No. 2, developed at the Lavochkin Research and Production Association (part of Roscosmos State Corporation), was delivered by air from Sheremetyevo International Airport to the Baikonur Cosmodrome.
In preparation for the launch of the Arktika-M spacecraft No. 2 passed a number of final stages: comprehensive electrical tests of the disassembled and assembled product; thermoelectric tests in a vacuum chamber; technological vibration tests of the product; control of the tightness of the propulsion system, control disclosures of all structural elements and many other checks.
At the spaceport, the Arktika-M spacecraft No. 2 will undergo pre-launch preparation, fueling and docking with the upper stage in the assembly and test building. The spacecraft will be orbited by a Soyuz-2.1b launch vehicle (RSC Progress, part of Roscosmos State Corporation) with a Fregat upper stage (NPO Lavochkin). The launch is scheduled for December 2023.

Roscosmos:
Yesterday in the assembly and test building of the 31st site of Baikonur Cosmodrome specialists of Roscosmos State Corporation enterprises performed general assembly of the Soyuz-2.1b space rocket with the Arktika-M hydrometeorological satellite No. 2.
Today the state commission authorized the rocket to be taken out and installed at the launch complex of Site 31 on December 13.
The launch of the Soyuz-2.1b launch vehicle with the Fregat upper stage and the Arktika-M spacecraft No. 2 is scheduled for December 16 at 12:17:48 Moscow time.
The Soyuz-2.1b launch vehicle was manufactured by the Progress Rocket and Space Center, while the Fregat upper stage and the Arktika-M No. 2 satellite were manufactured by the Lavochkin Research and Production Association (part of Roscosmos).
The first Arktika-M satellite was launched into orbit in February 2021 and, after flight tests in September 2021, was put into operation as part of the highly elliptical hydrometeorological space system Arktika-M. The presence of the Arktika-M spacecraft No. 2 in the system will ensure a continuous round-the-clock view of the northern territory of Russia and the Arctic region by two satellites that will alternate between each other in the working parts of the orbits.
In May 2023, Roscosmos State Corporation and NPO Lavochkin signed a government contract to modernize the Arktika-M system to increase its orbital constellation to four spacecraft. Arktika-M satellites No. 3, No. 4, No. 5 and No. 6 are scheduled to be built and launched by 2031. This will make it possible to halve the frequency of imaging of the polar region and make observations of the required area from different angles, as well as to detail ultra-short-term weather forecasts, increase the efficiency of detection and monitoring of natural hazards and emergencies, and increase the accuracy of cloud identification over snow and ice cover and determination of their characteristics in the Arctic region and adjacent territories.

I wonder if the Cryo tanks needed topping off? The truck you spotted was offloading into a door that is now covered up after leaving. Cryo tanks under the pad, interesting.

Yesterday, during flight tests, the hydrometeorological spacecraft "Arktika-M" No. 2 received and transmitted to Earth the first images of the Arctic region and adjacent territories.
The satellite is in an operational highly elliptical Molniya orbit with an equatorial inclination of 63.3 degrees, an apogee altitude of approximately 38,900 km and a perigee altitude of approximately 1,400 km. All of its service systems are functioning normally.
