New Payload Fairing from RUAG Space Enables Quieter Journey to Space

RUAG Space (CSA CSM) has successfully developed and tested a new, low shock jettison system funded by the Future Launchers Preparatory Program (FLPP) of the European Space Agency (ESA). The program develops technologies for future European launch vehicles and upgrades of existing launch vehicles. This system enables a quieter and...

LN2 Freezing of Live Bacteria in Dairy Products Boosts Productivity, Lowers Costs

GEA, an Australian electrical component company, has now launched a nitrogen freezing pilot plant for bacteria which takes a novel approach: freezing the bacteria in droplets using a liquid nitrogen bath outside the freeze dryer, then drying the pellets via the normal procedure. By freezing bacteria into pellets before drying,...

Thales Cryogenics, Eindhoven Receives NASA Awards

NASA has awarded the cryogenics department at Thales, Eindhoven two recognitions at its 2019 Honors ceremony held at the Jet Propulsion Laboratory in Pasadena the week of November 11.

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Bose-Einstein Condensate

A Bose-Einstein condensate, first proposed in 1925 by Albert Einstein based on work done by Satyendra Nath Bose (the same Bose from whom the term boson is derived), is a super-cold state of matter in which almost all of the individual atoms have “condensed” down to the lowest possible quantum...

Cold Technology for Pest Control

While it does not reach temperatures cold enough to be called cryogenic, carbon dioxide snow is at the heart of a new way of dealing with unwanted pests. It utilizes a quick freezing process that takes advantage of the properties of carbon dioxide snow and has a number of benefits...
