I am not sure what you mean by bow wave. You are not using the right numbers. You have to add the numbers for Common Exploration Systems Development and Exploration Operations in order to make apples to apples comparisons between the FY23 and FY24 requests.

I bet they’re trading putting stuff in the trunk vs just biting the bullet and going for a Starship servicing.

Among many other options, yeah, although that would push any Hubble reboost / servicing several years into the future.

Rocket Lab is targeting early tomorrow morning for its second launch of the month, lofting a pair of satellites for BlackSky from LC-1B in New Zealand!

So if two vehicles are needed for Hubble servicing, then are we talking about a cargo dragon with the platform and equipment or something else?

It would be a separate structure with a small robotic arm, containing most of the hardware needed for replacing stuff on Hubble. This could be a very bare-bones structure, but at its most complex it could also be an airlock.

A cargo Dragon could plausibly deliver something like that, but this would be a big departure from the "little to no cost to NASA" pitch. It would take years to design and build before the mission could launch.

During the Constellation era, this was considered to be one of the things that the LEO variant of Orion could have done by launching on Ares I. There have been a variety of concepts for this idea. I'll attach a couple of pictures.

roverRange = (lunarDaylightLength - timeOnSite)*driveTimePercentage*speed/2

lunarDaylightLength = 14days
timeOnSite = 5days
driveTimePercentage = 50%
speed = let's say 8km/h

roverRange = 430km.  That's 1.5% of the lunar surface

If speed = 10km/h, roverRange = 540km.  2.4% of the lunar surface.

SpaceX Reusability / Re: Progress on rapid booster reuse

One of the keys to more rapidly reusing the Falcon 9 rocket was significantly increasing the water flowing into the pad during liftoff, reducing damage at Space Launch Complex-40 seen here. Also note the rapid "throwback" of the launch tower. Very important (and difficult to do).

Yet they attempted to do a dry pad for Superheavy?

Seems like there maybe a couple of SpaceX GSE folks that meet over a coffee.
