From the bottom, there is the cylindrical capsule containing paramagnetic crystals. Above this are connecting rods to transfer heat. Above this is the box-like structure that holds the microcalorimeter detector.
Outer wires carry signals from the detector.
The helium tank and superconducting magnet are not shown. The frame surrounding the dewar will hold the mirror assembly for the telescope. The Astro-E satellite in orbit. Launch date is planned for February 2000.
