Novel Superconducting Magnet Thrusters to be Tested Out on Space Station

A New Zealand research institute and U.S. commercial firm Nanoracks are combining to send a superconducting magnet technology demonstrator to the International Space Station to test a novel type of space propulsion. The Paihau—Robinson Research Institute intends to test a type of electric space thruster known as applied-field magneto plasma dynamic...

Cryogenics Specialist Orders First Satellite for Detecting Methane Leaks

Absolut Group, a French cryogenic technology provider, said Dec. 7 it has ordered a demo nanosatellite for a constellation that would use sensors at very low temperatures to detect greenhouse gas leaks. The company’s newly created Absolut Sensing subsidiary ordered the chassis for a 16U satellite it calls Gen1 from Lithuania’s...

Got Propane?

As the maritime industry mulls the ‘fuel of the future,’ a strong and growing case can be made for propane based on availability, cost and ease of use compared to competitive fuels. Darren Monzingo, president of FARO Industrial and VP of Engineering for GEM Marine, is a marine engineer and naval...

Trenta’s Final Fusion Test Campaign

In 2023, Helion Energy, Inc., an American fusion research company, will end operations on Trenta, its 6th fusion prototype. The team is now undergoing Trenta’s last-ever fusion test campaign. For two years, its scientists and engineers have carried out rigorous research to test the capabilities of this fusion machine. The Helion...

Eta Space Commissions Liquid Hydrogen Test Facility

Eta Space is excited to announce the commissioning of a Liquid Hydrogen (LH2) Test Facility (LHTF) now available at their location in Rockledge, Florida. Customers can test their hardware and materials using LH2 with the benefit of small batch production. Previously only available in large quantities at high costs, Eta...

Dewar

A dewar is a type of cryostat named after Sir James Dewar, the researcher who first developed the concept of a vacuum insulated container with silvered walls to reflect thermal radiation. Dewar was the first to liquefy hydrogen, and he created the device to store his discovery. The thermos bottle...

Stirling and Gifford-McMahon Cryocoolers

Stirling and Gifford-McMahon (GM) cryocoolers are two of the most commonly used cryocoolers in cryogenics. Both devices have a significant industrial base and operate at a wide range of temperatures and capacities. The thermodynamic cycles for both of these cryocoolers are quite similar. The Stirling cycle consists of a compressor,...

Liquefied Natural Gas (LNG)

A significant commercial application of cryogenics is the liquefaction, transport and storage of natural gas. Liquefied Natural Gas (LNG) is generally 95 percent methane with a few percent ethane and much lower concentrations of propane and butane. LNG liquefies at 111.6 K. Unlike many applications of cryogenics, the motivation for...

Cryogenic Treatment of Materials

F.J. Diekman Controlled Thermal Processing, Inc. info@metal-wear.com Cryogenic Processing (also called cryogenic treatment, and incorrectly “cryogenic tempering”) is a process that uses cryogenic temperatures to modify materials to enhance their performance. Cryogenic Processing involves the slow reduction in temperature of the material to at least -300°F (-185°C) and holding the...

Cryogenics in Space

Peter Kittel University of California-Berkeley pkittel@cal.berkeley.edu Space Cryogenics is the application of cryogenics to space missions. These applications fall into two broad areas, supporting space science missions and supporting the space transportation infrastructure. Science applications: The atmosphere is opaque to much of the electro-magnetic spectrum. In space, the absence of...
