Data

   The following are datasets from some LASP Programs which are available for viewing and/or downloading.

• Mariner 9: Mariner Mars 1971 Ultraviolet Spectrometer (UVS) Data

     This site provides access to the entire Mars orbital data set obtained by the LASP built UVS instrument from 1971 to 1972. The Principle Investigator was Charles A. Barth. THe Mariner UVS discovered Ozone on Mars and mapped CO2 seasonal distributions.

• MDC: Mars Data Conglomerator

     The Mars Data Conglomerator is a website that has access to multiple datasets of the surface and atmosphere of Mars. It allows users to specify a location on the surface, and dynamically generates views of that region using available datasets. It can combine datasets to create hybrid views, thereby providing insight that the databases alone cannot give.

• SME: Solar Mesosphere Explorer

     SME was operated from October 6, 1981 to April 14, 1989. Gary Rottman is the PI for the SME solar instrument.The solar ultraviolet (UV) irradiance from the Solar Mesosphere Explorer (SME) covers the spectral range from 115 nm to 303 nm in 1 nm intervals. The uncertainty for the SME solar irradiances is 10-20% (larger at shorter wavelengths).

• SNOE: Student Nitric Oxide Explorer

     SNOE ("snowy") is a small scientific satellite that is measuring the effects of energy from the sun and from the magnetosphere on the density of nitric oxide in the Earth's upper atmosphere. The spacecraft and its instruments were designed and built at LASP. SNOE was launched on February 26, 1998, and is now being operated from the mission operations center at the LASP Space Technology Research building.

• UARS: Upper Atmosphere Research Satellite

     One of the main UARS science goals is to understand better the ozone chemistry and trends in the upper atmosphere. Ozone abundance is known to change naturally by solar UV variability, dynamics in the polar regions, and by man's influence such as CFCs. UARS was launched in September 1991 from the Space Shuttle Discovery during the STS-48 mission.

Software Tools

   LASP staff develop tools which focus on solving problems related to mission operations and scientific data analysis. These general purpose packages are available to others who wish to use them.

• Albatross: Mariner Mars 1971 Ultraviolet Spectrometer (UVS) and TeleVision Camera (TV) visualization tool

     This program (written in IDL) allows the user to view any location of any size of the surface of Mars. The surface can be one of topography (MGS MOLA), visual wavelength photographic (Viking MDIM), thermal inertia (MGS TES), or geology (USGS GEO). Requires download on a UNIX or Linux compatible system, and v5.4 or higher of IDL.

• CASPER: Cassini Sequence Planner Software

     This package allows a graphic visualization of virtually any solar system object from the point of view of the Cassini spacecraft. Observation sequences can be designed, modified, saved, and viewed using CASPER. These sequences can be distributed to other CASPER users for their input and information. CASPER makes use of "Modules" from the Cassini Module Dictionary for observation design which allow users to determine the optimal parameters for individual observations. CASPER estimates the slew times between individual observations within a session, but it is not intended to be a scheduler. Rather, it shows users what types of observations can be achieved at different times in the orbital tour and computes how long the observations will take. The graphical presentation gives users information on resolution and geometry of observations, and CASPER is able to compute detailed geometrical information such as phase angle distribution within a field of view.

• CITEP: Colorado Io Torus Emissions Package

     The Colorado Io Torus Emissions Package, or CITEP, is a computer package designed to simulate emissions from the Io plasma torus surrounding Jupiter. The many imaging and spectral observations of the torus covering nearly two decades necessitate a torus model for intercomparing the data sets. CITEP meets this need by allowing the user a wide range of flexibility while incorporating up-to-date magnetic field models and atomic physics.

• GGS: Geometry and Graphics Software

     GGS is a multi-mission tool to help planetary scientists visualize the geometric conditions under which their data were obtained. It allows the user to access spacecraft geometry information, formatted in the NAIF SPICE kernel and Toolkit system, to display previously taken data. GGS can also be used to investigate and design future spacecraft/body opportunities and observations. Any mission whose spacecraft configuration can be represented by a) scan-platform mounted all-axis stabilized, b) body mounted all-axis, or c) body mounted spinning, could use GGS, especially those currently supported with SPICE kernel generation.

• OASIS-CC: Operations and Science Instrument Support - Command and Control

     OASIS-CC provides many functions necessary to monitor and control spacecraft and their scientific instruments. Developed by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado at Boulder, OASIS-CC communicates between users and their instruments during all phases of instrument development and use: testing, integration, and operations. (The term "instruments'' refers to anything OASIS-CC communicates with -- instruments, spacecraft, test equipment, and ground support equipment.) It receives instrument telemetry and extracts the individual data items, translates user commands into binary or ASCII formats expected by the instrument, and formats data for display to the user.

• OASIS-PS: Operations and Science Instrument Support - Planning and Scheduling

     The Operations and Science Instrument Support - Planning and Scheduling (OASIS-PS) is a software tool designed for resource-oriented planning and scheduling applications. The OASIS-PS system is written in Ada and has four major software subsystem components. The OASIS-PS software is designed to support a wide range of planning and scheduling applications and can easily be tailored via database modifications, DECwindows updates, and new rule base creation.
