Oh well, might as well start that new topic since it's already well advanced in the Juno area...
My perspective on landers is as follows. All the landers we've had so far were dropped blind onto an essentially unknown surface. Any future landers can be targeted for specific terrains. It really is not true that we have had representative landings. Even a descent image or two, a panoramic photo plus a bit of surface composition, from a simple Venera-class lander just updated a bit, would be useful if we could put several down at well chosen targets. My choices would be: Examples of the main plains units (smooth, fractured, ridged) tesserae high elevation radar-bright tesserae large fresh lava flow unit ('fluctus') crater dark parabola crater ejecta outflow unit dunes area. And I have always assumed, rightly or wrongly, that it would be relatively easy to put these down, so they ought to be fairly inexpensive as planetary landers go.

Lori Glaze just announced that fallout from the Psyche launch delay has pushed the VERITAS launch to 2031

A 2-year launch delay. (To answer the question I had reading this.) My recollection is that VERITAS was aiming for a 2028 launch. I think the reasoning is that the bulk of the MSR development (launch 2028) needs to be completed before switching to the ramp up for the VERITAS development. A 2031 launch would be the same as EnVision is believe. If I remember correctly, it will take ~2 years for EnVision to reach Venus and then do aerobraking to achieve the mapping orbit. Probably something similar for VERITAS. So, I' expecting the science mission for VERITAS to begin around 2033 (at least until we see a plan from the VERITAS team). And the announcement said that the VERITAS launch would be *no earlier than* 2031, not that 2031 was a firm date. -------------------- |

This still indicates (the old plan, no doubt) a July 2028 arrival for VERITAS, which would mean launch around the end of 2027.
https://solarsystem.nasa.gov/missions/veritas/overview/ While cruises to Venus of about seven months are possible and typical, note that Magellan, when plans were changed by the domino effect of Challenger and Galileo, ended up taking a long cruise of over a year to Venus. |
