The machining process covers many material removal procedures; among them, grinding is one of the most important. Improved grinding is crucial to improve the overall machining process; hence, many researches focused on enhancing the performance of grinding operations by focusing on factors like wear, chattering vibrations, grinding wheel topography, temperature, and force surface roughness.

Establishing sustained operations on the moon and Mars presents a multitude of opportunities and challenges NASA has yet to encounter. Many of these activities require new technologies and processes to ensure the agency is prepared for its ambitious Artemis missions and those beyond. One of those challenges is working with cryogenic fluids, meaning fluids existing in a liquid state between minus 238 degrees Fahrenheit and absolute zero (minus 460 F). These fluids – liquid hydrogen (the most difficult to work with), methane, and oxygen – are vital to spacecraft propulsion and life support systems. The fluids may also be produced in the future on the lunar and Martian surfaces via in-situ resource utilization (ISRU).

During the intense heat of summer and throughout the humid Florida fall, Airmen donned protective gear to handle, manage, and deliver over 19,000 gallons of liquid nitrogen at temperatures below minus 300 degrees Fahrenheit to support a three-month munition test at Eglin Air Force Base.

Two space infrastructure specialists, Space Machines Company and Spaceium, have joined forces to embark on what they believe to be the first-ever cryogenic refueling space mission in space in 2025. Under terms of a signed agreement, Canada’s Spaceium will integrate its cryogenic storage technology into Space Machine’s platform. Spaceium will then refuel Space Machines’ tanks with cryogenic fuel using stored reserves.

As we enter 2024, the field of quantum computing continues to develop rapidly. Accessibility to quantum processing and the scaling of systems are key factors in the growing industry. Cloud-based services offer one potential access route to quantum processing, but systems are also being deployed for customers to host on-premises. Besides increases in accessibility, improvements are also needed in the quality of quantum bits, or qubits, themselves and the infrastructure that surrounds them. This includes scaling up the cryogenic infrastructure.

Fifty-Five Years of Inextricable Success-Superconducting Radio Frequency (SRF) cavities are vitally central to SRF accelerators, boasting a Q factor about 10⁵ times higher than copper cavities and the capability to produce accelerating fields (Eacc) on an order of magnitude greater than copper in CW. In the 1960s, SRF cavities were delicate instruments used by pioneering scientists in several prestigious labs. Over the past 55 years, the synergy between cryogenics and SRF accelerators has consistently proven mutually beneficial and successful. Today, the landscape has evolved significantly, with potential markets for industrial electron beams reaching $10 billion annually. Various SRF cavities mainly made from Nb (Figure 1)^[1-2] are widely used in high energy physics, nuclear science, FEL, XFEL, synchrotron lights, computer chips, and medical and industrial applications. 

High temperature superconducting (HTS) tapes, which have emerged over the last decade, are enablers for new technologies. Specifically, high temperature superconducting magnets to enable commercial fusion energy are arguably the most tantalizing and potentially impactful. Fusion energy would be a long-envisioned source of firm, safe, carbon-free electricity whose successful development requires creative, innovative cryogenic engineering. 

Antarctica is vital for cold research, from understanding our fragile climate to tracking local fauna. Energy is critical to this research as it supports expeditions and heating bases. Reliance on diesel import is leaving a dark legacy on the continent, as the buildup of black carbon is causing accelerated rates of animal birth defects and melting ice shelves.^[1,2] We must transform our Antarctic fueling practices with urgency if we are to preserve our last clean continent. 

ExxonMobil’s affiliate Esso Nederland BV plans to build a pilot plant at its Rotterdam manufacturing complex to test a breakthrough technology that could significantly reduce CO2 emissions from key industries. The pilot plant aims to obtain data on performance and operability of the carbonate fuel cell (CFC) technology, jointly developed with FuelCell Energy. Additionally, the pilot aims to address potential technical issues that may occur in a commercial environment and better understand the costs of installing and operating a CFC plant for carbon capture.

Before architect César Martín-Gómez could send his latest thermoelectric experiment to Antarctica in 2018, he had to make sure that soldiers from the Spanish Army could get it right on the first try. In the laboratory, he could always run the experiment—a scale model of a solid-state thermoelectric heater—a second time if it needed troubleshooting.

A cryo-EM and GPCR expert, a virtual screening pioneer, and a virtual chemical library creator walk into a bar. The result is not the opening line of a joke but rather the founding of a start-up that will rapidly discover novel small-molecule therapeutics through the virtual screening of AI-generated virtual libraries. That company, Deep Apple, launched with a Series A commitment of $52 million from life sciences venture capital firm Apple Tree Partners.

There are three locations in the world where helium can be sourced. One is Qatar, another is in Texas and the third is right here in Wyoming at an ExxonMobil facility near La Barge. Called Schute Creek, it produces about 20% of the world’s helium.

When NASA's VIPER (short for Volatiles Investigating Polar Exploration Rover) lands on the surface of the Moon on a mission to better understand the environment where NASA plans to send astronauts as part of the increasingly complex Artemis missions, its journey will be guided by the ingenuity of its human team - and several key tools that use artificial intelligence. From helping the science team choose a landing site at the lunar mountain Mons Mouton, to planning out its path, the VIPER team has developed and used artificial intelligence algorithms to help assess risk and optimize decision making.

A team of researchers working on DARPA's Optimization with Noisy Intermediate-Scale Quantum devices (ONISQ) program has created the first-ever quantum circuit with logical quantum bits (qubits), a key discovery that could accelerate fault-tolerant quantum computing and revolutionize concepts for designing quantum computer processors.

NASA’s James Webb Space Telescope observed the exoplanet WASP-80 b as it passed in front of and behind its host star, revealing spectra indicative of an atmosphere containing methane gas and water vapor. While water vapor has been detected in over a dozen planets to date, until recently methane – a molecule found in abundance in the atmospheres of Jupiter, Saturn, Uranus, and Neptune within our solar system – has remained elusive in the atmospheres of transiting exoplanets when studied with space-based spectroscopy. Taylor Bell from the Bay Area Environmental Research Institute (BAERI), working at NASA’s Ames Research Center in California’s Silicon Valley, and Luis Welbanks from Arizona State University tell us more about the significance of discovering methane in exoplanet atmospheres and discuss how Webb observations facilitated the identification of this long-sought-after molecule. These findings were recently published in the scientific journal Nature.
