Roscosmos presented engines for a space tug

The Keldysh Center, which is part of Roskosmos, showed at the Army-2022 International Military-Technical Forum a marching electric rocket propulsion system based on the KM-10 Hall engine.

Roscosmos presented engines for a space tug

It is designed to solve transport problems, for example, as part of space tugs and manned stations, or to solve the problems of final insertion of a spacecraft from a reference to a target orbit with the possibility of subsequent correction of its orbit.

The main components of the system are: the propulsion unit (motor and flow control unit), the conversion and control system, the working fluid supply unit and the working fluid storage unit.

The KM-10 engine can operate within a wide range in terms of power (1.5–15 kW) and discharge voltage (300–900 V), providing high performance in terms of efficiency (up to 65%) and specific thrust impulse (up to 3000 s). At the same time, life tests at 500 V at a power of 10.5 kW demonstrated the almost complete absence of erosion of the output rings, which provides unprecedented resource characteristics.

Also at the Army-2022 forum, the Keldysh Center presented a correction system for light geostationary spacecraft based on the KM-60 engine, which is the first system in the world based on a Hall-type engine with an accelerating voltage of 500 V, which saves up to 25% of the working fluid ( xenon) relative to domestic and foreign analogues.

Some of our clients didnt believe the data until they

Micron has already started shipping HBM3 Gen2 memory to Nvidia, and the testing results seem to be very impressive.

“Some of our clients didn’t believe the data until they put it to the test.”  HBM3 Gen2 memory is already being tested by Nvidia

The memory is being supplied for testing only: mass production apparently has not yet begun. However, it is already clear that new memory can significantly speed up products that will use it.

In the hands of our customers we have samples that, compared to those of our competitors, simply amaze everyone.

In fact, power consumption is so much lower with higher performance that some of our customers didn’t believe the data until they put it to the test.

Micron Business Director Sumit Sadana

Unfortunately, Micron has not yet presented any indicators, although we have data from the announcement. Let’s remember that we are talking about 24 GB of memory per stack with a throughput of more than 1.2 TB/s and energy efficiency two and a half times higher than the previous generation of HBM.

HBM3 Gen2 memory is expected to be used in Nvidia Blackwell compute accelerators, which could appear as early as next year. Such memory is unlikely to appear in gaming video cards, although GDDR7 will also offer an impressive increase in performance compared to GDDR6X.

China’s SMIC is only four years behind TSMC and Samsung, although US sanctions should keep the gap to 10 years

Chinas SMIC is only four years behind TSMC and Samsung

The Chinese company SMIC has recently become much more famous due to the fact that, as it turns out, it has mastered the 7 nm process technology and successfully released the Kirin 9000s SoC for the new flagship Huawei smartphones on it. A fresh report shows that SMIC is at most four years behind the semiconductor market leaders.

China's SMIC is only four years behind TSMC and Samsung, although US sanctions should keep the gap to 10 years

At the same time, US sanctions pressure was intended to keep China at a distance of 10 years from leaders, including TSMC and Samsung.

US authorities view the emergence of the Kirin 9000S as a serious threat. However, this cannot be said that sanctions do not work or that China will quickly close the existing gap. Bloomberg says Chinese companies, including SMIC, are finding it increasingly difficult to purchase advanced EUV lithography equipment. Such equipment is produced in large quantities and in a form suitable for the specified tasks, in fact, only by the Dutch ASML, and it is prohibited from selling installations to China. As a result, the transition from a 7 nm process technology to some more modern one, that is, at least 5 nm, may become an insurmountable obstacle for SMIC while sanctions are in effect.

At the same time, it recently became known that China is at least trying to create an advanced lithograph operating on a particle accelerator, which will be able to produce products at 2 nm standards.
