Cassini Mission to Saturn

http://speclab.cr.usgs.gov

The Cassini Visual and Infrared Mapping Spectrometer (VIMS) instrument is an imaging spectrometer with the following capabilities:
Specification VIMS
Wavelength Range 0.35 - 5.1 microns
Number of Channels 352 (96 Vis, 256 IR)
Spectral Sampling ~7 nm Vis, ~16 nm IR
Bandpass (FWHM) ~7 nm Vis, ~14 nm IR
Pixel Size 0.5 milliradian
Spatial Image Size 64 x 64 pixels

The VIMS has two optical systems, one for the 0.35 - 1.0 micron wavelength region, and the second for the 0.86 - 5.1 micron wavelength region.

The VIMS is a spatial imager with a field of view of 64 by 64 pixels. VIMS imaging is very flexible: it can be a point spectrometer, obtain 12x12, 1xn images and could obtain continuous swath data of 64 pixels by N pixels with spacecraft motion. With spacecraft pointing, large images of hundreds of pixels per side may be obtained.

The 0.5 milliradian field of view means that VIMS will resolve a 0.5 km spot at a distance of 1,000 km. By mosaicing multiple fields of view, VIMS will produce images of Saturn, its rings and moons comparable to and sometimes better than Voyager images, but with full 352 spectral channels at each pixel. The spectral range and spectral resolution will allow detailed compositional mapping of minerals on the satellites and rings of Saturn, and of gases in Saturn's atmosphere. VIMS will image surface detail on Titan at infrared wavelengths, cutting through the thick haze which blocks views of the surface at visible wavelengths.

Thermal vacuum testing proved VIMS is a capable and stable instrument with no wavelength shifts in any of its modes or as a function of temperature.

Cassini was launched October 15, 1997 and will arrive at Saturn in July, 2004 after flying by Venus, the Earth and Jupiter. Launch image (200 K gif)


The Cassini Spacecraft flew by Venus on April 26, 1998 at about 5:45 am MDT (Earth received the signal about 7 minutes later: 5:52 am MDT). The flyby altitude was 283.75 km, a value only 0.003% from the targeted value--that is an error of only about 9 meters!!! Cassini is now Traveling at over 141,000 km/hour (on April 26, 1998).


The Cassini Spacecraft flew by Venus a second time on June 24, 1999. Everything went as planned. The VIMS-V channel obtained data on Venus. Data were downlinked over the following few days (low gain antena) and received. Everything looks great.


Cassini flies by Earth August 17, 9:28pm MDT. The VIMS IR covers have been jetisoned, VIMS IR is cooling down and will take data on the moon during the flyby. The data will be through the full VIMS instrument (0.3-5 microns) and throught the solar calibration port in order to obtain important solar calibration data. The data will be used to calibrate VIMS measurements at Jupiter and Saturn to reflectance.

At Aug 17, 1999 15:10 UTC (9:10 am MDT) the VIMS IR detector had cooled to 81.5 Kelvin--excellent. All spacecraft systems are reported nominal.

Cassini Orbit Insertion July 1, 2004 (UT).
