ISRA is a combined XRFXRDImaging Instrument for Lunar Applications

1
In-Situ Resource Analyzer (ISRA)

• ISRA is a combined XRF/XRD/Imaging Instrument for
  Lunar Applications
• XRF X-ray Fluorescence
• XRD X-Ray Diffraction
• MI Microscopic Imager
• ISRA is a Lunar Mission variant of the MICA
  (Mineral Identification Composition Analyzer)
  Instrument
• MICA was originally developed for application at
  MARS via the Mars InstrumentDevelopment Program
  (MIDP)
• INSTRUMENT KEY FEATURES
• NO SAMPLE PREPERATION IS REQUIRED --A capability
  unique to this instrumentXRD/XRF/Imaging all
  available in a single device
• Instrument is useful in a variety of modes and
  scenarios For example, canfunction as a Deck
  Mounted Instrument, or on a Lander/Rover Arm
• Low mass with small footprint. Minimal
  Mass/Volume Impact on Lander/Rover. I made some
  minor changes to reduce the wording.

ISRA Origins Developed originally for Mars
(MIDP) Ideal for lunar environment TRL
--Brassboard/Flight prototype MIDP goals were
to demonstrate functionality of miniature
compositional analyzer that could rapidly
provide data relevant to resource evaluation,
geology and astrobiology

ISRA Mission Science

• ISRA properly positioned on Lunar Lander Deck
  will examine upper surface soils deposited on
  Instrument surface during Landing
• No Deployment required in this application

ISRA Mission Science
KEY ISRA Mission Science Features

• This Mission provides a unique opportunity to
  Sample and Analyze the Top-Most Layers of the
  Lunar Regolith
• Sample Material will be deposited on the ISRA
  Analysis Station through Entrainment by Retro
  Thruster Plume
• The Upper Layers of Regolith Fines is the
  Feedstock Material are Targeted for Lunar Oxygen
  Production using an In-Situ Resource Utilization
  (ISRU) Process
• ISRU Oxygen production supports Lunar Base for
  Breathing Gas and Propellant Oxidizer
• ISRA analyses are highly effective on samples
  containing small particles
• ISRA will Analyze Lunar Material in several ways
• X-Ray Fluorescence (XRF) to determine the
  Elemental Composition
• X-Ray Diffraction (XRD) to determine Mineral
  Content and Grain Size Information
• Microscopic Imager (MI) to provide Visual Context
  of sample and data on Particle Size Distribution

ISRA Instrument Features This Application

• Single ISRA Data Analysis Packet Approx 4.1
  Mbyte
• Visual Image Data Approx 2.5 Mbyte
• X-ray Analysis Data Approx 1.5 Mbyte
• Instrument Header Data Approx 0.1 Mbyte
• (Note Data can be further compressed if
  necessary)
• ISRA Instrument Parameters
• MASS Approx 2.0 kg
• POWER Avg 10 Watts for duration of analysis to
  power x-ray tube/electronics
• ANALYSIS TIME 20-90 minutes (depending on
  requirements)
• Notes
• 1) Experiment time-line includes visual image
  acquisition, sensor cool-down, x-ray data
  acquisition, and data packet generation.
• 2) Assumed MICA design changes to adapt from
  Mars to lunar environment. For example, the
  Thermal Electric Cooler (TEC) and associated
  power supply have been eliminated CCD cooling
  for single analysis will be provided via LN2 from
  a small dewar)
• Budget (ROM)
• Assumes a 30 month program, provides Qual and
  Flight Units
• YR 1 (2.5 M), YR 2 (1.5), YR 3 (0.7)
