LCROSS Astronomer Workshop Support

Special thanks to the Science Mission Directorate at NASA Headquarters (especially Jim Green & Kelly Snook) for funding the travel grants.

Thanks also to the Lunar and Planetary Institute (LPI) for providing logistical support for the Workshop.

Supported also by NASA’s Exploration Mission Directorate (ESMD), Lunar Precursor Robotic Program (LPRP), and LCROSS Project.

6LCROSS Observation Campaign

The LCROSS mission has multiple layers of observing

• Bright Impact Flash• Thermal OH Production• Rapid Thermal Evolution

• Expansion of Plume• Thermal Evolution• H2O ice sublimation• Photo-production of OH

• Residual Thermal Blanket• Expanding OH Exosphere

The combination of ground-based, orbital and in-situ platforms span the necessary temporal and spatial scales: from sec/meters to hours/km

7LCROSS Goals

The LCROSS mission goals:

• Confirm the presence or absence of water ice in a permanently shadowed region on the Moon

• Identify the form/state of hydrogen observed by at the lunar poles

• Quantify, if present, the amount of water in the lunar regolith, with respect to hydrogen concentrations

• Characterize the lunar regolith within a permanently shadowed crater on the Moon

8Worldwide Observing Campaign

Worldwide observation campaign -- building on the experience of Deep Impact

Lunar, Earth-orbiting , and Ground-based Assets

9Observational Platforms

1. LCROSS Shepherding Spacecraft

2. Lunar Reconnaissance Orbiter

3. International lunar missions

4. Earth-orbital assets

5. Ground-based telescopes

10Observing Opportunities

Observations during 1) lunar swing-by and 2) LCROSS impacts.

Opportunity to cross-calibrate instruments, also

test communications during mission between LCROSS Science Operations Center

and observing Astronomers.

11Communications

Observation Campaign Coordinator (Heldmann) will be in direct communication with Astronomers from the Science Operations Center

(SOC) during lunar swing-by and LCROSS impacts.

12Astronomer Support

NASA recognizes that Astronomers must be compensated

(funded) for time, travel, etc. to ensure optimal planning of

observations, acquisition of data, analysis of data, and

delivery of results (to NASA, scientific community, public, etc).

13Astronomer Support

NASA recognizes that astronomers must be compensated

(funded) for time, travel, etc. to ensure optimal planning of

observations, acquisition of data, analysis of data, and

delivery of results (to NASA, scientific community, public, etc).

Solution: Selection of qualified observers who are eligible to receive

direct support for observations in support of the Lunar CRater

Observation and Sensing Satellite (LCROSS) lunar swingby

calibration and LCROSS impact, and support of subsequent data

analysis and delivery to the Planetary Data System (PDS).

14Identification of Qualified Observers

* Astronomer must have successfully secured observing time on a professional telescope (and notified NASA) by December 2008 to observe the LCROSS impacts (Feb 2009).

* Observations must be relevant to LCROSS and NASA lunar goals (ESMD & SMD). In particular the observations should address those goals identified in the LCROSS Science Plan and those others relevant to Lunar Science as identified by the Lunar Exploration Analysis Group (LEAG).

* Astronomer must agree to open sharing of data within the LCROSS Science Team and other Astronomers included in the "umbrella" proposal as soon as data is collected and throughout the 3-month data analysis period after impact (Feb-April 2009).

* Astronomer must provide completed analysis to LCROSS Project by April 2009 (in time for inclusion in final LCROSS Report to NASA HQ).

* Astronomer must follow established PDS guidelines and deliver their dataset to the PDS by July 2009.

* Astronomer must work for a U.S. institution in order to be eligible to receive funds.

* International partners may participate on the team (assuming they meet the other aboverequirements) on a non-funded basis.

15Funding Logistics

• Upon successfully securing observing time, astronomers may submit a funding proposal.

• Proposals will undergo screening to ensure they meet the qualification and selection criteria (TBD).

• Selected proposals will receive funds after a data analysis reported is accepted.

16Two Stages of Funding

1. Pre-Impact Observational Support

Pre-impact observational support provided to Astronomers.

2. Data Analysis Support

Post-impact data analysis and PDS delivery support to Astronomers.

17Notional Timeline

18A few notes ….

• This LCROSS Observation Campaign funding for astronomers is above and beyond the typical ROSES funding programs.

• Astronomers are not precluded for applying for additional funding through ROSES.
