DESCRIPTION:Abstract: I will discuss the development of a multi-stage magne
 tic cooling system at NASA's Goddard Space Flight Center. The device\, bas
 ed on adiabatic demagnetization refrigerators (ADRs)\, is designed to cont
 inuously cool detectors at 0.05 K and optics at 4 K with high thermodynami
 c efficiency. We made significant progress in developing the system\, incl
 uding the production and testing of a single-stage 10-K-to-4-K ADR\, the a
 ssembly of a two-stage 10-K-to-4-K CADR\, and the fabrication and assembly
  of a four-stage 4-K-to-0.05-K CADR. Despite challenges\, including a lack
  of access to key personnel and lab resources due to sudden emergence of f
 light work early in the development and later due to COVID-19\, we are now
  successfully testing the system and optimizing its performance. This tech
 nology is currently baselined in four different instruments for future spa
 ceflight missions.\n\nCo-sponsored by: Virginia Commonwealth University\,
