Liftoff. The Artemis II mission launched from @NASAKennedy at 6:35pm ET (2235 UTC), propelling four astronauts on a journey around the Moon. Artemis II will pave the way for future Moon landings, as well as the next giant leap — astronauts on Mars.










It would have been lovely to reference this amazing image of the F1-75 rear suspension assembly inside the gearcasing by @carpentiers_f1 amidst the rear suspension affairs of the 2025 season. However, I completely forgot of its existence. It perfectly represents the constraints of having the pullrod layout at the back. Although there is no guarantee the layout remained the same up until '25, I personally feel it provides good insight nonetheless. I don't recall seeing any images of the following car's rear subframe assemblies. Note that they are using belleville stacks for the heave spring. Torsion bars are mounted vertically. A perfect look at how little room there is for larger dampers at the bottom of the casing. The heave damper is limited by the proximity of the driveshaft practically exhausting all the available space with this particular layout. Larger vertical footprint, they risk contact with the driveshaft. I recall the driveshaft having its own separate shrouding in pre-22 cars but doesn't seem to be the case here.

Things not on my 2025 bingo card: Kyle Benjamin driving a racecar. Well, he's back, driving a Pro Late Model at New Smyrna. Where'd he go? How'd this come about? Is this the start of a second run at racing? Those answers in this @RacingAmerica story: racingamerica.com/news/late-mode…

Rear axle broke and went over the wall along with the LR tire. LF came off with impact to the wall and also went over the wall @JakeGarcia14 @racewithstars @RaceFairgrounds 📸 Jason Reasin


This tire situation is mostly on the teams and their choices. Here is my explainer on why tires are failing for @Motorsport: motorsport.com/nascar-cup/new…
