Titan's inventory of organic surface materials (2008)
Lorenz, Ralph D., Mitchell, Karl L., Kirk, Randolph L., Hayes, Alexander G., Aharonson, Oded, Zebker, Howard A., ...
Cassini RADAR observations now permit an initial assessment of the inventory of two classes, presumed to be organic, of Titan surface materials: polar lake liquids and equatorial dune sands. Several...

Cassini RADAR observations of Enceladus, Tethys, Dione, Rhea, Iapetus, Hyperion, and Phoebe (2007)
Ostro, Steven J., West, Richard D., Janssen, Michael A., Lorenz, Ralph D., Zebker, Howard A., Black, Gregory J., ...
The Cassini mission includes 34 investigations of Saturn’s icy satellites by the 2.2-cm-wavelength (13.8-GHz) RADAR instrument, operating both as a scatterometric radar and a passive radiometer....
Soderblom, Laurence A., Kirk, Randolph L., Lunine, Jonathan I., Anderson, Jeffrey A., Baines, Kevin H., Barnes, Jason W., ...
Titan's vast equatorial fields of RADAR-dark longitudinal dunes seen in Cassini RADAR synthetic aperture images correlate with one of two dark surface units discriminated as “brown” and...
Design and Results of Differential Microwave Radiometers (DMR) on COBE (2004)
Janssen, Michael A., Gulkis, Samuel, Bennett, Charles L., Kogut, Alan J.
The Differential Microwave Radiometer (DMR) experiment on the Cosmic Background Explorer is in the final year of a scheduled four years of operation to measure large- and intermediate-scale...
Boric-Lubecke, Olga, Denning, Richard F., Janssen, Michael A., Frerking, Margaret A.
The mass and power of a heterodyne spectrometer must be greatly reduced to satisfy small space mission constraints. We report on a 220 GHz receiver, requiring less than 4.8 W, with a mass of 1.25 kg....
Novel LO Frequency Control for a 220 GHz Radiometer with a 110 GHz GUNN Oscillator (2004)
Boric-Lubecke, Olga, Denning, Richard F., Janssen, Michael A., Frerking, Margaret A
Because of the drive for
Boric-Lubecke, Olga, Denning, Richard F., Janssen, Michael A., Frerking, Margaret A.
Mass and power for the next generation of NASA's heterodyne spectrometers must be greatly reduced to satisfy the constraints of future small-spacecraft missions. Here we present a new receiver...
Compact Hererodyne 220 GHz Receiver For Planetary Spectroscopy (2004)
Boric-Lubecke, Olga, Frerking, Margaret A., Janssen, Michael A.
Solar System spectroscopy yields information about the physics, chemistry and dynamics of planetary atmospheres. Many molecular species, such as CO,water have very strong spectral emission lines in...
INTRODUCTION Our knowledge of the composition and physical properties of planetary atmo- spheres is for the understanding of the origin and evolution of the planets themselves, as well as for...
Direct Imaging of the CMB from Space (1996)
Janssen, Michael A., Scott, Douglas, White, Martin, Seiffert, Michael D., Lawrence, Charles R., Gorski, Krzysztof M., ...
Fundamental information about the Universe is encoded in anisotropies of the Cosmic Microwave Background (CMB) radiation. To make full use of this information, an experiment must image the entire sky...
