Midcourse Space Experiment (MSX)
The MSX observatory is a Ballistic Missile Defense Organization project which offers major benefits for both the defense and civilian sectors. It was launched on a Delta II vehicle on April 24, 1996, into a 900 km, polar, near-Sun synchronous orbit. The spacecraft featured an advanced multispectral image capability to gather data on test targets and space background phenomena.
The infrared sensors operated at 11 to 12 degrees Kelvin by employing a solid hydrogen cryostat. The IR instruments span the range 4.2 - 26 microns. The focal plane array consists of five bands and the radiometer beam-size is more than 25 times smaller than IRAS. As a result, much greater spatial resolution than anything currently available has been obtained. The cryogen phase of the mission ended on 26 February 1997. During the ten month cryogen phase of the mission over 200 Giga Bytes of data on Celestial Backgrounds were obtained.

Zurich Solar Radio Spectrometer
The Radio Astronomy Group (RAG) of ETH in Zurich, Switzerland, recorded solar radio spectrograms with an analog spectrometer called Daedalus (1974-1993) in the range of 100-1000 MHz. Its observation list can be accessed directly. Two digital spectrometers, Ikarus (1978--1985) and PHOENIX (1988--1994), cover a range from 100--1000 MHz and 0.1--3 GHz, respectively. And since 1998 the new and improved Phoenix-2 Spectrometer covers a range from 0.1 -4 GHz. These data can be accessed by the ASPECTimage retrieval system. Their observation list contains references to frequency programs that indicate which frequencies were observed. More information can be obtained from RAG members. - Categories: center radio solar
