Slide1

Alternative Observation Strategy for the Fermi Mission-

A

RecommendationSlide2

Motivation5th anniversary of the science phase of the

Fermi

mission

Continued

evolution of

Fermi

science

program

and

With eye

to the future extended

Fermi

mission

phase (i.e. SR)

Due

consideration should be given to alternative observing

strategies Slide3

ProcessWhite papers

were solicited from

the community

began

17 January

2013

ended on 27 March 2013.

5

WPs,

including

1 each

from the Fermi GBM and LAT

teams

From the beginning this was viewed as a collaborative process. Teams helped any groups requested information

A one-time committee was formed. Two meetings

One

telecon

in early July. Decided to review 3 or 5 WPs in detail

A face-to-face meeting with committee, LAT team, GBM team, FSSC, NASA HQ, and Fermi

Committee Recommendation

We recommend that the Fermi mission undertake a new observing strategy that emphasizes coverage of the Galactic center region (i.e. “Option 4”

or similar

). This recommendation should be adopted with the following conditions

:

Implementation should occur by December 2013. The time between now and then is needed to solicit community comment on the recommendation and to run some observatory thermal modes to better understand the impact of this new observing strategy.

The modified observing strategy should run for one year.

After one year is up, the

Fermi

Project Scientist will organize a review to decide whether to maintain the modified observing strategy or return to survey mode.Slide7

Motivation for a Revised Science Program

The world’s observatories have dedicated programs

Increased sensitivity to these PSRs
