• No4onal package of Key Science Projects developed in 2015 based on
  the highest priority science objec,ves that were recommended by the
  science community that were:
    • Consistent with capabili,es of the SKA1 design
    • Consistent with a realis,c observing schedule filled at approximately 50% for
      the first 5 years of scien,fic opera,ons
• Indica,ve KSP policy (actual policy will be determined by SKAO Council)
    • Only scien,sts from SKA member countries may lead a KSP
    • KSP Leadership is guaranteed to be distributed amongst SKA members in
      propor,on to their financial contribu,on
    • KSP par,cipa,on (at the non-Leader level) is guaranteed to be distributed
      amongst SKA members in propor,on to their financial contribu,on
    • KSP par,cipa,on (at the non-Leader level) of SKA non-members is capped at

• Outcome of well-documented SKA1 science priori,sa,on process
   • All objec,ves originate with the science community
   • Review and strong endorsement by advisory bodies (SRP, SEAC)
• Should be viewed as representa(ve package of high-impact science
  deliverables for the first five years of science opera,ons
• Actual list of high impact poten,al projects already much broader
   • SWG number has grown from 8 to 13
   • SWG membership has grown fourfold from 2014 to 2019

                                                                                                                     13
KSPs: Next steps
• Further develop KSP concepts
   • Regular workshops to provide a forum for open discussion of KSP concepts

• Support development of poten,al KSP collabora,ons
   • There will ul,mately be a compe,,ve process of KSP proposal submission,
     evalua,on and alloca,on
   • Regular workshops to provide a forum for the key areas of interest of par,cular
     communi,es to be presented, leadership aspira,ons to begin to be iden,fied and
     resourcing strategies to begin development

• Maximizing commensality
   • It is likely that the same data stream will serve mul,ple KSP or PI-led groups, each
     with limited data rights to address specific scien,fic objec,ves
   • Regular workshops to provide a forum for early discussion of support for such
     commensal programs, including the development of efficient survey strategies
     intending to maximise the scien,fic return of the KSP package
