Yes, two. Falcon 9 (and occasionally Falcon Heavy) and now New Glenn.
Two of SpaceX's Super Heavy boosters (B14 & B15) were each caught & subsequently reused once before being disposed of, but not yet to truly send Starship (or a payload) orbital - which was never in the flight plan yet anyway. It's only a matter of time before they do.
My Performance MX is technically working perfectly (discounting the nasty disintegrating rubber coating which is the only reason why I've had to stop using it) on Win11 Pro (24H2) using the last version (6.90.66) of Setpoint from https://support.logi.com/hc/en-gb/articles/360025141274-SetPoint, so it should work for you barring any possible group policy put in place on your work machine to prevent it.
Came to say the same.
I put off buying a replacement for the 13yr old Logitech MX Performance Mouse which lost most of its rubbery coating over the last couple of years, but still worked perfectly until the rubber on the scroll/flywheel completely disintegrated earlier this year.
I've been using an almost as old, hard-plastic bodied Logitech G600 MMO gaming mouse as a daily replacement, but I really miss the wireless freedom of the MX Perf, as well as that lovely flywheel. So while not completely devoid of rubber surfaces, this MXM4 is heading in the right direction.
<q>... I kinda wonder if when the report says it's fresh/potable water, it's being extracted from the wells around the Texas site where from memory, fraccing water had been dumped so if that's the source....</q>
All of the water is trucked in from Brownsville where it's taken directly from the potable water supply. This has been confirmed by the folks over at NSF, amongst many others, who've seen the trucks filling up and then heading off down Highway 4 to the Boca Chica launch site.
The plans for the water extraction on site was abandoned due to the high salt content and other contaminants that would definitely affect the environment, but also damage the equipment.
I think a pulley/ratchet strap mechanism on the outside would probably work, with all of the motors & cable/strap take up spools located at the nozzle end so that it pulls the nose end towards the nozzle, instead of something (linear actuator) pushing the nose end as in the video.
You could then have a parachute package in the nose cone to be able to recover the collapsed stack of nose cone & engine puck.
If it needs to survive re-entry temps, then an inflatable heatshield a la LOFTID (https://en.wikipedia.org/wiki/Low-Earth_Orbit_Flight_Test_of_an_Inflatable_Decelerator) would also pack down quite neatly into the nose cone.
Note that the FCC (Federal COMMUNICATIONS Commission) licence linked to in the article is a rolling renewal of one that SpaceX have applied for every six months, for the last couple of years, and is just for the RF communications coverage used for a launch.
This has nothing to do with an actual launch licence from the FAA (Federal AVIATION Authority) which will likely only be applied for & then issued a few weeks before SpaceX is actually ready to perform an orbital launch attempt.
This confusion resurfaces every time the rolling renewal of the FCC RF Comms licence comes around.
If it wasn't for SpaceX, then even more of your precious tax dollars would've been wasted on pork barrel cost-plus job programs with no end in sight, and no coherent vision for the future.
Also SpaceX have significant funding from sources outside of US Government agencies.
In addition, while Jeff Who spaffed $500 million on a mega-yacht (which has an additional separate super-yacht just for landing his helicopter on it), Elon Musk sold all his other homes, and now lives in a small bungalow in Boca Chica right next to the Starship production site.
