Back to articleThis graph shows the transfer time and xenon propellant mass as functions of the power generated on the SEP tug. The left axis shows the transfer time from 0 to 350 days. The right axis shows the xenon propellant mass from 0 to 30,000 kg. The x-axis shows the array power from 200 to 800 kW. The curve representing the transfer times starts in the upper left at approximately 320 days at 270 kW. It decays approximately exponentially to the lower right to a value of approximately 130 days at 850 kW. The propellant mass increases linearly from approximately 17,500 kg at 270 kW to 24,500 kg at 85 kW.
