## Mars Scout Overview 

- Steve Matousek/Karen McBride
- July 21, 2004

- The work described here was performed at the Jet Propulsion Laboratory, California Institute of Technology under contract with the National Aeronautics and Space Administration.

## Outline

- Why Mars Scouts?
- What are Mars Scouts?
- When is a Scout likely to launch?
- Summary of Concepts to Date
- Pre-AO Studies
- Proposals in Response to AO
- Scout Technologies
- Future Work

## Why Mars Scouts?

- Achieve program science goals not otherwise covered in the baseline plan.
- Optimize the use of limited resources to accomplish the best science.
- Provide the flexibility to quickly respond to discoveries at Mars.

## Scouts in the Next Decade

## What are Mars Scouts?

- PI-led missions:

**Orbital**

**Network**

**Lander/Rover**

## Changes from Scout ‘07 to ‘11?

- Cost cap increased to $400M (FY ‘03)
- Longer time in schedule for studies at all steps (pre-AO, Step 1, Step 2)
- Technology from Mars Technology Program Low Cost Missions area may be applicable
- Mars infrastructure in place (MRO, MTO)

## May ‘01 Scout Workshop

- Encourage Community Cross-Fertilization
- Select 6-10 Concepts for Further Study
- Selected Concepts Help Scope ‘02 AO
- Possible Science
- Needed Technology
- Cost/Schedule/Risk
- 43 Concepts Submitted, 10 Selected
- Selected Concepts DO NOT Prejudice AO

## Summary of MayWorkshop Concepts

## Summary of Pre-AO Study Areas

**Ten Concepts Selected for Study**
- (~$150K each)

## Ten Selected Scout Studies

| --- | --- | --- | --- |
| Landers/Rovers | The Urey Mission | Plescia (USGS) | Lander/Rover for age dating. |
|  | The NAIADES | Grimm (Blackhawk Geoservices) | Low-frequency electromagnetic sounding for groundwater. |
|  | Artemis | Paige (UCLA) | Multiple polar small landers to the north and south poles. |
|  | Cryoscout | Carsey (JPL) | North Polar probe melts into ice. |
|  | PASCAL | Haberle (ARC) | Global meteorology network. |
| Orbiters | Mars SAR | Campbell (Smithsonian) | Global imaging radar from orbit. |
|  | Mars Atm Const Obs | Kursinski (UA) | Radio sounding of Mars atmosphere from multiple orbiters. |
|  | Mars Env Obs | Janssen (JPL) | Orbital observation of Mars’ atmosphere. |
| Aerial | KittyHawk | Calvin (UNR) | Multiple gliders observing Valles Marineris. |
| Sample Return | SampleCollection for Investigation of Mars | Leshin (ASU) | High altitude Martian dust collection and return to Earth via Mars atmospheric flyby. |

## Scout ‘07 AO Summary

- $325M (FY ‘03) Cost Cap
- Launch by Dec. 31, 2007
- Full Missions
- Missions of Opportunity ($25M)
- Selected mission(s) reside in the Mars Exploration Program

**FLASHBACK**

## Scout ‘07 Proposal Summary

- 18 Full Mission Proposals (2 non-compliant)
- 2 Orbiters
- 4 Landers
- 2 Networks
- 5 Rovers
- 4 Aerial
- 1 Atm/Dust Sample Return
- 5 Mission of Opportunity Proposals
- MOO cancelled (CNES Premier orbiter cancelled)

**FLASHBACK**

## Step 2 Scout Selections(alphabetical order)

- ARES (Aerial Regional-scale Environmental Survey), Joel Levine, NASA LaRC
- MARVEL (Mars Volcanic Emission and Life Scout), Mark Allen, NASA JPL
- Phoenix, Peter Smith, Univ. of Arizona
- SCIM (Sample Collection for Investigation of Mars), Laurie Leshin, Ariz. State Univ.

**FLASHBACK**

## Scout ‘11 Draft Schedule

- Note: schedule and content subject to change

- Pre-AO workshop (before pre-AO studies): Feb '05
- Scout pre-AO studies: Mar - Sep '05
- AO: Feb '06
- Step 2 selection and kickoff: Sep '06
- Selection for flight: May '07
- Nominal launch date: Nov ‘11

## General Scout Technologies

- Lightweight Propulsion Components
- Tanks
- Filters, Regulators, Valves
- Thrusters (Low Min Impulse Bit [mN])
- Lightweight telecomm components
- Antennas
- Transmitters
- Receivers
- Power Generation (lightweight, long-life, small volume)
- Minimum mass structures
- Low mass, low power, small volume instruments

## Scout Instruments

- New instrument capabilities can enable new Scout class missions
- Instrument technology needs to be responsive to Scout limitations (for example, small missions, focused science)
- Mass, power, volume, cost are all drivers in Scout missions

## Future Work

- Get 2011 Scout moving (it’s been awhile since May ‘01 workshop)
- Foster MTP technology infusion into potential Scouts
- FY ‘05 Pre-AO Studies (like the ‘01/’02 Scout Studies)
- 2006 AO for 2011 Opportunity

- Mars Scouts are an Exciting 			Addition to the Mars Program!
