Jeff Foust [@jeff_foust] (March 30, 2023). "In a presentation at Space Science Week, Sue Smrekar says the earliest VERITAS can now launch is late 2029, which she argues is preferable over 2031 to deconflict with DAVINCI and EnVision and lower overall cost. Need "modest" bridge funding in FY23 and 24 to do so" (Tweet) – via Twitter.
