  From the above presentation to the NASA Advisory Council- Human Exploration & Operations presentation:
  
  Acquisitions in Work:
  - GOES-T (Launch Service Task Order is already in work, so presumably the LV has been chosen but contract isn't yet finalized or announced)
  
  Acquisitions not currently in Work:
  - Restore-L 
  - IXPE
  - Lucy
  - Psyche 
  - Europa Clipper (Congress mandated to use SLS, so not likely to ever see an acquisition)
