ISS Science for Everyone

Science Objectives for Everyone
The instruments on the Solar facility are gathering data outside of Earth’s atmosphere which is increasing our knowledge of solar radiation and how this varies. This is important both to Earth-based and space-borne systems as well as to advanced studies on climate. For example the data can be used within computer simulations to anticipate the influence of solar radiation on our environment.

    Experiment Description

    Research Overview

    • Solar-SOLSPEC (Sun Monitoring on the External Payload Facility of Columbus -Sun Monitoring on the External Payload Facility of Columbus -SOLar SPECtral Irradiance Measurements) is the observation of the solar spectrum irradiance from 180 nm to 3000 nm on board the International Space Station (ISS) with the following aims:
      • Achievement of absolute measurements (with uncertainties of 2 percent in UV and 1 percent in the visible and infrared light)

      • Study of solar variability over both short and long-term scales during solar cycle 23.

      • Correlative studies between the spectral and the total solar irradiance, utilized in other instruments on the ISS, (Sun Monitoring on the External Payload Facility of Columbus-SOlar Variable & Irradiance Monitor, Solar-SOVIM and Sun Monitoring on the External Payload Facility of Columbus-SOLar Auto-Calibrating EUV/UV Spectrophotometers, Solar-SOLACES) and the atmospheric and climatological implications of their variabilities.
    • The measurement of the solar spectral irradiance in the domain of 180 to 3000 nanometers is related to the aeronomy and climatology of the Earth and its atmosphere, and to Solar Physics (the mechanisms and processes of solar radiation and its variability).

    Description
    The purpose of the experiment is to measure the solar spectum irradiance from 180 nm to 3000 nm. The aims of this investigation are the study of solar variability at short and long-term periods, and the achievement of absolute measurements (2 percent in UV and 1 percent above).

    The Solar--SOLSPEC instrument is fully refurbished and improved with the experience gained from previous missions (Spacelab-01, Atlas-1, Atlas-2, Atlas-3, Eureca).

    Applications

    Space Applications
    The awareness of the environment of the Earth and of the sun radiation level and spectrum is of importance to both Earth-based and space-borne systems as well as to advanced studies on climate. Monitoring the sun radiation outside of the Earth atmosphere over a large electromagnetic spectrum and correlating with parallel observations with other space missions and on ground helps provide the accurate data required to support predictive models and anticipate on the influence of sun radiation on our environment.
