Electrifying Space: Zenno’s fuel-free satellite pointing system

New Zealand-based space-flight systems company, Zenno Astronautics (Zenno), has proudly announced a remarkable achievement—surpassing a staggering $75 million in product sales (equivalent to USD 48 million) for its groundbreaking innovation, the Z01™ superconducting magnetorquer for spacecraft attitude control. At the heart of Zenno’s success is the Z01, a revolutionary satellite...

World-First in Oman

A momentous event unfolded as the world’s first-ever liquefied hydrogen carrier, Suiso Frontier, graced the shores of Sultan Qaboos Port in Muscat on August 14. Proudly crafted by the renowned Kawasaki Heavy Industries (KHI), this marks the long-anticipated debut of Suiso Frontier in the Sultanate of Oman. The name “Suiso”...

Breakthrough Enables Quench Detection in High-Field Magnets for Fusion Reactors

Researchers at Berkeley Lab’s Accelerator Technology & Applied Physics (ATAP) Division have developed a method for detecting and predicting the local loss of superconductivity in large-scale magnets that are capable of generating high magnetic fields. These high-field magnets are a core enabling technology for many areas of scientific research, medicine...

NASA Rocket Hardware Prepped for Shipment to Space Coast

With Artemis teammates and media watching, United Launch Alliance (ULA) crews guided the interim cryogenic propulsion stage (ICPS) for NASA’s SLS (Space Launch System) rocket for Artemis III to the loading dock at ULA’s facility in Decatur, Alabama, July 31. ULA’s R/S RocketShip will transport the flight hardware to ULA’s...

Transfer Lines

Transfer lines may in some real sense be thought of as the cryogenic fluid analogy of current leads. While current leads carry electrical power to where it’s required in a cryogenic system, transfer lines do the same with cryogenic fluids. Transfer lines range in complexity from very simple U-tubes containing...

Zero Boiloff

Zero Boil Off cryostats are those that contain liquid cryogens but are designed to eliminate or vastly reduce the boil off of  the liquid. These cryostats combine some of the advantages of Cryogen-Free systems (e.g. ease of use and long operational lifetime) with the advantages associated with a reservoir of liquid...

Cryomodule

Cryomodule is a term that is most commonly used to refer to cryostats that contain superconducting radio frequency (SRF) cavities. Such cavities are used to accelerate charged particle beams and are a major component of modern particle accelerators. Using the term cryomodule to refer to cryostats containing SRF cavities appears...

Magnets

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. Particle physics uses accelerators to recreate the conditions of the early universe in an attempt to piece together the complex puzzle of how we got to where we are today. These huge machines are used...

Energy Storage

From “Superconductivity: Present and Future Applications” by the Coalition for the Commercial Application of Superconductors. With power lines increasingly congested and prone to instability, strategic injection of brief bursts of real power can play a crucial role in maintaining grid reliability. Small-scale Superconducting Magnetic Energy Storage (SMES) systems, based on...

Astronomy

ASTRONOMY IN SPACE by Peter V. Mason, retired,  Jet Propulsion Laboratory, and Visiting Associate, California Institute of Technology. Pmason@alumni.caltech.edu In thinking about the reasons to perform astronomy in space, we first consider the effect of the earth’s atmosphere.  On a scale of decreasing energy, gamma rays, cosmic rays, X-rays and...

Cryocoolers

What is a Cryocooler? A mechanism that can extract heat from an object (cooler) and by doing so draw its temperature down below approximately 150 Kelvin (cryo). — (Courtesy Dr. Willy Gully) What is the difference between a Cryocooler and a Cryostat? A cryostat is any device designed to maintain...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
