Delays can occur when getting data back from spacecraft in deep space. The challenge stems from a combination of distance from Earth and limited spacecraft power.
In an effort to increase the rate of data collection from those spacecraft, researchers at NASA Glenn are developing ultra-sensitive receivers that can pick up on signals coming from spacecraft very far away.
Senior Technologist Bob Romanofsky uses liquid nitrogen to test the devices called Superconducting Quantum Interference Filter-Based Microwave Receivers in a new laboratory clad in a special alloy. The shielded room not only prevents electric field interference but also magnetic field interference to enable sensitive noise measurements.
The technology is a fusion of the world’s most sensitive magnetic field detector and a novel antenna system. The receiver technology is intended for next generation deep-space network applications.
