GSFC XMM-Newton GOF Status Report #126: AO-6 Release / NASA Dear Colleague Letter
NASA is pleased to call to the attention of members of the U.S.
scientific community the release by the European Space Agency (ESA)
of the Announcement of Opportunity (AO), "XMM-Newton Call for
Observing Proposals", soliciting Guest Observing proposals for the
sixth cycle (AO-6) observing program for ESA's X-ray Multi-Mirror
Mission (XMM-Newton). The subject Announcement solicits proposals
for observations to be performed during a 12-month period commencing
in May 2007. Due to the nature of the NASA-ESA bilateral agreement,
proposals from scientists affiliated with U.S. institutions only are
solicited by this Letter; others are advised to contact ESA directly.
U.S. scientists may propose either as Principal Investigators or as
Co-Investigators on proposals with non-U.S. PIs (foreign PI proposals).
The AO may be accessed directly from ESA at the following address:
The XMM-Newton Guest Observer Facility (GOF) at the Goddard Space
Flight Center (GSFC) is the support center for XMM-Newton activities
in the U.S. Information of interest to U.S. observers, as well as
general project information, can be found at the following address:
A detailed description of the mission, including instrument
capabilities and additional information pertaining to the proposal
preparation and submission procedures, is also available via links
from the XMM-Newton home page at that address. (General questions
concerning XMM-Newton and participation by U.S. investigators should be
addressed to firstname.lastname@example.org.) ESA will be responsible
for conducting a peer review of all submitted proposals, including
those from U.S. investigators, and determining the associated time
allocation. Current plans call for ESA to notify proposers and NASA
of the results of the peer review in early January 2007.
As for Cycles 1-5, NASA has allocated funding for a Guest Observer
(GO) program to support the analysis, interpretation, and publication
of data obtained by U.S. proposers who are granted Open Time observing
on XMM-Newton through the ESA AO. The level of funding available for
any approved program will depend on the total funding available, the
size and complexity of the investigation, whether the proposed budget
is for a PI or lead Co-I (for foreign PI proposals), on the
ultimate number of U.S. investigations approved by ESA, and possibly
on other factors. Note that higher priority is assigned to U.S.
PI proposals; funding for Co-I participation in foreign-PI
proposals is allocated at a reduced level (roughly one-half of the
U.S. PI level for an equivalent proposal). We anticipate that
approximately $5.5 M will be available for support of U.S. Guest
Observers under AO-6. Details regarding the timing and mechanism of
NASA's solicitation for data analysis funding requests will be
announced after the results of the ESA peer review have been released;
please do not submit a budget with your observing proposal.

participation in the XMM-Newton mission, please contact:
