Subject: Exploration Systems Architecture Study Briefing, 9/19 @9 a.m.
Importance: High

All,

Good evening.

As promised, NASA has completed the Exploration Systems Architecture Study (ESAS).  The ESAS study has accomplished the following tasks:

* Development of a reference Lunar exploration architecture concept to support sustained human and robotic Lunar exploration operations.

* Definition of top-level requirements and configurations for crew and cargo launch systems to support the Lunar and Mars exploration programs.

* Identification of key technologies required to enable and significantly enhance these reference exploration systems, and a re-prioritization of near-term and far-term technology investments.

* Complete assessment of the top-level Crew Exploration Vehicle (CEV) requirements and plans to enable the CEV to provide crew transport to the International Space Station (ISS) to reduce the gap between Shuttle retirement and initial development of CEV and the crew launch system (CLV).

We appreciate your patience over the last few months and would like to offer the opportunity to provide you with a briefing on the ESAS.  On Monday, September 19th at 9:00 a.m., NASA will provide a 1 hour briefing on the ESAS results.  The briefing will be held in the Program Review Center (9H40), from 9:00 a.m. to 10:00 a.m. Two members of the ESAS team, Marsha Ivins, who heads the Exploration Branch of the Astronaut office, and Doug Cooke, Acting Associate Administrator for the Exploration Systems Mission Directorate, will brief the ESAS results. Schedule permitting, Administrator Griffin would also like to stop by and say a few words about the study results.

If you are able to attend this briefing and discussion, please RSVP to me (susan.t.laver@nasa.gov) or call me at (202) 358-3884.  Providing a RSVP will allow us to obtain advance clearance with security for entrance into the building as well as provide our office background on who has received the brief.  Please note that we have limited room and will need to limit attendees to no more than two representatitves from each organization.  I apologize in advance if this is an incovenience and appreciate your patience.

Cordially,
Susan Laver
