Subsurface properties and early activity of comet 67P/Churyumov-Gerasimenko
Subsurface temperatures showed seasonal and diurnal variations, which indicated that the submillimeter radiation originated at depths comparable to the diurnal thermal skin depth of comet 67P/Churyumov-Gerasimenko.
The COBE Mission: Its Design and Performance Two Years after Launch
COBE, NASA's first space mission devoted primarily to cosmology, carries three scientific instruments to make precise measurements of the spectrum and anisotropy of the cosmic microwave background…
TOPEX/Poseidon microwave radiometer (TMR). III. Wet troposphere range correction algorithm and pre-launch error budget
The authors describe the development of the statistical, two-step algorithm used for the TMR retrieval of path delay and results indicate that the inherent algorithm error is less than 0.4 cm of retrieved path delay for a global representation of atmospheric conditions.
Dipole Anisotropy in the COBE Differential Microwave Radiometers First-Year Sky Maps
We present a determination of the cosmic microwave background dipole amplitude and direction from the COBE Differential Microwave Radiometers (DMR) first year of data. Data from the six DMR channels…
MIRO: Microwave Instrument for Rosetta Orbiter
The European Space Agency Rosetta Spacecraft, launched on March 2, 2004 toward Comet 67P/Churyumov-Gerasimenko, carries a relatively small and lightweight millimeter-submillimeter spectrometer…
TOPEX/Poseidon Microwave Radiometer (TMR). I. Instrument description and antenna temperature calibration
The TMR instrument and the radiometric instrument calibration required to derive antenna temperature (T/sub A/) from the raw digital data are described and a significant improvement over those of the Seasat and Nimbus-G Scanning Multichannel Microwave Radiometer on which TMR is based is described.
The lakes of Titan
These northern-hemisphere lakes constitute the strongest evidence yet that a condensable-liquid hydrological cycle is active in Titan’s surface and atmosphere, in which the lakes are filled through rainfall and/or intersection with the subsurface ‘liquid methane’ table.
The Sand Seas of Titan: Cassini RADAR Observations of Longitudinal Dunes
The most recent Cassini RADAR images of Titan show widespread regions that appear to be seas of longitudinal dunes similar to those seen in the Namib desert on Earth, and the distribution and orientation of the dunes support a model of fluctuating surface winds.
