Pertinent Facts

Phase II Flight Safety Review will be held during the week of May 21-25, 2007

Phase II will be held at a facility near Johnson Space CenterFacility will be offsite, but will still require a

level of registration, not as difficult as NASA badging.

Letter will be sent with registration requirements in advance of meeting once building and current requirements understood.

Phase II Safety Review

Meeting is conducted by the Payload Safety Review Panel and chaired by their Chairman.

The purpose of the meeting is to audit our compliance with relevant requirements.We will present design and operations to

the PSRP.We will present hazard reports and

support technical informationPSRP will interrupt with questions frequently.

Phase II Safety Review

Focus will be on safety related systems and not the science of the mission.PSRP will be interested in hearing about

science, but that is not their focus.We must be prepared to talk about the

hazardous systems that we’ve identified in the Phase II safety data package.

Mission success is often discussed but in context of the maintenance that is required to attain it.We are not using maintenance in their context

with the AMS-02.

Agenda and Presentation

An Agenda will be prepared in advance to organize our presentations. Will evolve as we move forward, draft agenda is in work. Two days are anticipated for technical presentations, and

three days for hazard reports and discussion. Rehearsal at CERN TIM in April

Will send out presentation outline by end of January Presentations will have to focus on design,

construction and function to educate the PSRP on the hardware and operations.

Presentations will be coordinated for content for content and timing prior to meeting.

Presentations

Keep presentations direct and with graphics intended for discussing the topic and up to dateAssume PSRP knows nothing about the payload

and system, as if they have not read the safety data package.

The PSRP Reviews well in excess of 200 payloads in a year, they will always try and draw corollaries between what we say and what they’ve heard before.

The questions you may hear may seem out of context and silly, but there is likely a lot of history as to why it was asked, it probably means we didn’t explain something as fully as we thought. We answer and move on.

Presentations and Backup

We need to balance the depth of data in the presentation with additional data that we can carry with us and have ready to display on need.We will wait for the need and not

volunteer extra data without call, that can become a trap too of going down the wrong road on topics.Even with five days, we have a lot of

information to get through

Success Notes

Presentations should be clear and easily read. Cute backgrounds and animations make fine

selling points, but we need to focus on getting the information clear and transferred easily.

Small type and colors with low visibility/contrast should be avoided.

Safety Panel has acronyms from two major program and dozens of smaller projects in their heads, we need to keep our acronyms and abbreviations well defined.

Mind your borders and keep relevant data back from them, projectors can’t always be trusted to be aligned.

Success Notes

Our Data needs to be up to date. Late changes should be presented clearly, but should also

be coordinated with Safety Engineer in advance. Closed verifications are good things to bring to add to for

this meeting.

Discussions should be in whispers before we take it before the PSRP Better yet, take them outside of the meeting room, the

microphone system picks up whispers some of the rooms.

There will likely be PSRP members that are participating by telecon, we need to have presentations ready in advance so that they have a copy.
