Presentation Transcript

  1. Outline • Science goals, mission name (bonus for acronym and logo!!) • Define telescope and instrument • Choose orbit • Calculate data volume, rate and downlink • Calculate pointing requirements • Select spacecraft bus • Determine launch mass • Select launch vehicle • Describe major risks • Estimate total mission cost

  2. 1. Science goals • Major science goals and relevance to field • Mission name (and acronym/logo)

  3. 2. Define telescope and instrument • Wavelength • Size • Sensitivity • Resolution (spectral and angular) • Thermal Requirements • Duration

  4. 3. Choose orbit • Consider data rate, background noise, launch cost

  5. 4. Calculate data volume and rate • Calculate data volume and rate • Is this consistent with orbit and downlink capabilities?

  6. 5. Calculate pointing requirements • Use the least stringent pointing needed to accomplish the science

  7. 6. Select spacecraft bus • Depends on size of instrument, telecom capability, pointing capability

  8. 7. Determine launch mass • Telescope • Bus • Instrument • Propellant • Margin

  9. 8. Select launch vehicle • Mass • Orbit • Cost

  10. 9. Describe major risks • Unusual size • New technologies • Below guideline margins

  11. 10. Estimate total mission cost • Telescope • Bus • Instrument • Launch vehicle • Operations • Reserves
