VSOP-2 Mission of Opportunity ProposalSAMURAI
Science of AGNs and Masers with
Unprecedented Resolution in Astronomical Imaging

• David Murphy JPL

SAMURAI Science Goals

• By making the highest resolution images in
  astronomy SAMURAI will
• Understand how supermassive black holes generate
  ultra-relativistic jets and powerful gamma-ray
  emission
• Constrain the nature of dark energy by making
  the most accurate measurement of the Hubble
  constant
• SAMURAIs science goals are well aligned with
  NASAs research astrophysics objective
• Understand the origin and destiny of the
  universe, phenomena near black holes, and the
  nature of gravity
• Synergy with NASA missions GLAST, JDEM, Chandra,
  HST

VSOP-2 MO Proposal SAMURAI

• Want to obtain VSOP-2 support via Partner Mission
  of Opportunity (MO) proposal submitted in
  response to current SMEX and MO Announcement of
  Opportunity (AO)
• 70 M available for MOs but NASA wants to fund
  more than one MO
• We want SAMURAI proposal to be at 30-35M
• But 30 contingency required ? 30-35 M/1.3
  23-27 M
• SAMURAI proposal schedule
• 28-Sept-07 AO released
• 16-Nov-07 Notice of Intent due
• 26-Nov-07 Internal JPL science review
• 18-Dec-07 Internal JPL TMC review
• 15-Jan-08 Proposal deadline
• May 08 Selection for Phase-A studies (target) ?
  150-300k
• Sep 08 Phase-A studies (target)?
• Jan 09 MOs selected (target)

MO Science Requirements

• MO proposal must contain a well-defined science
  investigation
• MO science investigation is conducted by MO
  science team
• U.S. PI and Co-Is (funded by NASA)?
• Non-U.S. Co-Is/collaborators (not funded by
  NASA)?
• NASA will evaluate only this science
  investigation for content and feasibility, and
  not the sponsors entire mission
• Synergistically supporting ongoing space science
  missions factored into scientific merit
  calculation
• Extended mission, guest investigator and general
  observer programs are not considered part of the
  scientific merit of the proposed MO
  investigation

Japan-U.S. KSP Meeting Oct 07

• Meeting goal
• To review VSOP-2 Key Science Programs and
  determine who undertakes which program
• Why meet now?
• U.S. Mission of Opportunity (MO) to support
  VSOP-2 MUST be submitted on Jan-15 2008
• VSOP-2 MO MUST contain a well-defined science
  investigation
• Need to determine what this science investigation
  is and how it fits into Key Science Programs
  (KSPs) already being developed in Japan
• Need to make sure all mission partners are happy
  with KSPs being developed and who has
  responsibility and leadership for which KSPs

VSOP-2 Mission Elements

• ASTRO-G spacecraft (JAXA/ISAS)?
• Dedicated Astro-G tracking stations
• Usuda (JAXA/ISAS)
• Yebes, Spain (OAN)
• 1 in S. Hemisphere (JPL) probably DSN Canberra
  site maybe South Africa
• Ground radio telescopes
• 10-element VLBA (NRAO)?
• EVLA, GBT (NRAO)?
• DSN 70-m?
• EVN, Japan, Korea, China, Australia, S. Africa,
  ...
• Correlators
• VLBA (NRAO), EVN, KVN,
• Analysis software
• AIPS/CASA (NRAO),
• Orbit determination
• JPL, ISAS
• KSP science teams SAMURAI, others
• Scheduling/planning Japan, U.S.? ,

NASA HQ Interactions

• Alan Stern is NASA selection official for MOs
• May 07 Inoue (ISAS director)-Stern (Head of
  NASA science) exchange of letters
• Aug 07
• Murata/Murphy/Ulvestad-Morse/Hasan/Salamon NASA
  HQ meeting
• Inoue-Stern NASA HQ meeting
• Inoue-Elachi (JPL director) meeting Elachi now
  on ISAS visiting committee
• Nov 07 Stern NRAO HQ visit
• Dec 07 Stern/Morse space science meeting at
  ISAS

Final Thoughts

• I hope we submit a successful SAMURAI proposal
• However, SAMURAI proposal will either be selected
  or rejected
• What to do we if it is rejected?
• Depends on how is was rated by NASA (hopefully
  get a Cat II)?
• If highly rated could try MO again (but lose a
  year)?
• Try to develop some other funding strategies

• Fewer interfaces reduces risk
• Each interface requires a letter of commitment
