Lunar Regolith Excavation Has No Working Solution — 50 College Robots Compete at Kennedy to Change That

Six weeks after Artemis II’s crewed lunar flyby, the engineering gap blocking a Moon landing goes to the test floor Fifty college teams open three days of autonomous robot trials at Florida’s Kennedy Space Center on Tuesday, testing what may be the single most stubborn engineering problem on the path...

Fermilab and Northern Illinois University Expand Quantum Workforce Pipeline with New Academic Initiatives

Fermilab and Northern Illinois University (NIU) have signed a Cooperative Research and Development Agreement (CRADA) to launch a specialized Master of Science in Physics program focused on quantum science and technology. The inaugural class is scheduled to begin in the fall of 2026, with students transitioning to hands-on research at...

Bluefors Joins Chicago Quantum Exchange

Bluefors has joined the Chicago Quantum Exchange, strengthening CQE’s Midwest roots as the region expands efforts to build a quantum supply chain, expand innovation capacity, and scale a quantum workforce. Bluefors plays a vital role in all three areas. We opened our first US-based Bluefors Lab in Chicago last year,...

NASA Set to Test Orbital ‘Gas Station’ Technology to Propel Moon and Mars Missions

NASA’s LOXSAT mission aims to test orbital fuel transfer, potentially turning spacecraft into “gas stations in space” for lunar and Mars missions. A groundbreaking NASA mission could soon transform how astronauts travel to the moon and beyond. The upcoming Liquid Oxygen Flight Demonstration (LOXSAT) will test critical technologies for storing...

AI has a power delivery problem. Superconductivity offers a path forward

AI is changing what power delivery must do, and new approaches are required Growing AI energy demand is not only forcing data centers to address generation challenges, but also how power is delivered. As power density rises and timelines tighten, high-temperature superconductors (HTS, also known simply as superconductors) are moving...

Molecular Qubit Achieves Single-Photon Quantum Control

A team of researchers report a single organic molecule can now store, manipulate and read out quantum information one molecule at a time using light. They add that their work hints at a possible new quantum modality built from chemically engineered molecules rather than fabricated semiconductor defects. The study, published...

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...
