  8. LISA Formulation • LISA Formulation study nominally ended end of 2006 • Mid-term review in 2006 • Baseline architecture consolidated • Upon ESA request: Assessment of potential cost-saving options • What should have happened next: • Formulation phase (Phase A) followed by a Definition phase (Phase B1) • Usually competitive study • About 1 year • Followed by Detailed Design Phase (Phase B2) leading into PDR • PDR by 2008/early 2009

  9. LISA Formulation • What happened instead • Formulation study extended into 2008 • Anticipation of some design issues • Technology studies have started • ITT for “point ahead” issued • ITT for laser development, telescope and pointing mechanism will follow upon consolidation of optical bench design • What will happen in the future • Depends on the timely readiness of LPF • Launch in end 2009/early 2010 • LISA PDR most likely only after LPF results are in (2010/11 ?)

  10. BEPAC • In the US, LISA is part of the Beyond Einstein Program • NASA funding problems affected the whole Science Program • In addition JWST overruns have hit the Science Program • Prioritization of BE missions was foreseen for 2008/2009 • LISA • Constellation X • Einstein Probes (Dark Energy, Black Hole Finder, CMB Polarization) • NASA and DoE decided to move the review forward to 2007 • Requested by DoE (partner in the Dark Energy Probe, now called JDEM) • NASA and DoE agreed to have the NAS conducting an independent review • Beyond Einstein Program Assessment Committee (BEPAC)

  11. BEPAC • BEPAC is charged with • Establishing the first mission to be implemented in the Beyond Einstein Program (BE1) • Lay the grounds for a later assessment by the Decadal Review (2008) to establish the further priorities • Not to preclude the Decadal Review (?) • Assess the science only, no programmatics • Report is due in September 2007 • 4 Panel meetings • Associated “town hall” meetings to poll the opinion of the locals • Projects were issued a list of about twenty questions • Resulted in 65 pages of answers • 780 pages of additional material

  12. ESA development • ESA Science Programme is “overheated” • With current budget planning, programme is locked up until and beyond 2015. • Community pushes for an AO for new missions • DG and Council chartered a Science Programme Review Team to review the management of the Science Directorate • Report not yet public but • “120%” rule • Free up at least 200 MEuro for the AO • LISA and Solar Orbiter are the only missions with no industrial commitment • Solar Orbiter has been re-confirmed by SPC • LISA has insufficient funds allocated in current budget.
