Virginia GOP official resigns after he called for Pentagon chief to be lynched
The Republican chairman of a Virginia electoral board has stepped down after a racially charged Facebook post he made about Defense Secretary Lloyd Austin and others came to light last week.

David Dietrich, the former chairman of the Electoral Board in Hampton, resigned Saturday — two days after his social media posting was discovered and prompted Gov. Glenn Youngkin (R) and other GOP lawmakers to call for his removal.

In a post from February 2021, Dietrich targeted Austin and retired Army Lt. Gen. Russel Honoré — both Black men — in a post, using the N-word and calling for “a good public lynching.”

Probably good that lynching is now a federal crime.

Blue Origin has some innovative tech. They seem to be choosing elegance where Musk is building almost a steam locomotive. But Musk’s aggressive development program is yielding results. The first Starship stack is flight-ready, but the FAA is seriously dragging its heels on the site environmental assessment. Third delay to April 29, until the next delay that is.

But perhaps if we make this planet habitable..?

No! Planets are cradles. We emigrate, build great thousand-mile wheel worlds of nickel-iron, then slowly scrub every last trace of our having been there off of it and let it go full wild. Someday it will yield another sentient race. This might not even have been the first go.
Your way risks navel-gazing stasis and ultimate collapse of the species.
Our immediate destiny is space. Flat interplanetary space, not at the bottom of a hole. Kuiper objects and asteroids will yield riches no planet can.
Our immediate next job is to ditch meat as our substrate. Then, like everyone else we go vewwy vewwy qwiet.

I think that cat is out of the bag. Public space is happening hand over fist. Should Elon go full Colhaagen, there’s always Space Force. And (shades of the Caribbean) I would not be surprised if national entities discreetly field privateers.

That said, I don’t like Starship much. It can barely haul its fat ass into low earth orbit, and would need perhaps a dozen tanker runs to go to cislunar or deep space. A big problem is that Super Heavy is estimated to quit at about 2.7 km/s realized in order to have recovery propellant, which puts a 5.3 km/s burden on Starship (plus maybe 150 tons payload) to achieve LEO. To go anywhere rom there, there is a “multiple Starship tanker runs” need to replace Starship’s propellant. That should give it enough propellant to do the Moon and Mars.
For Mars, mission planners would be wise to launch two Starships and tie their noses together with a mile of tether and spin them. The “gravity” will make for a healthier happier crew. No more two hours a day strapped to a treadmill.

are they designed for that? the floors would have to be arranged so that out was down, or else everyone would be walking on the walls and having to flip out of the doorways.
if musk was serious about this stuff, he would build a moon base and start stocking things up in it now. perhaps even ship the big fat ass ship up there in pieces and launch it from there, for a LOT less fuel, and building a moon base would give them practice for mars, and a chance to try out their building techniques in a hostile environment

Tie their noses together and down stays down. Thrust axis is centrifugal axis. Might have to reinforce the nosecone to deal with tensile load.

this woman is a threat to the security of the country...why isn't she in a cell in guantonamo bay? that is where they keep terrorists, real or suspected, isn't it? she has made incendiary remarks on the floor of the senate, and in the halls of the senate, she aided and abetted trump's incompetent, failed insurrection attempt, and now she is undermining the US military...as little as 20 years ago, hell, 10 years ago, she would have been branded the mentally unstable, potentially dangerous person she is, and been barred from ever serving in the government or the armed forces...

they have to have forward propulsion, how do you provide that with them linked together and spinning for artificial gravity?

Here’s my concept. Spin them during the long coast phase. Spinup, spindown and minor course corrections are done by computer control using the rcs. During extended delta vee, which is only for transmartian injection, setup for aerobraking, and boosting for Earth return, they’re not tethered.

I do wonder how they’re gonna keep the methalox from boiling off during the long Hohmann segments. A sunshaded radiator pointed into cold space might do.

of course, that isn't for two linked ships, but you would imagine they could work the math out

wouldn't hydrogen/oxygen fuel provide more power in a smaller space? is it much more volatile that methalox?

Hydrogen has two huge downsides: it has one-fifteenth the density of water. Only liquid helium-3 is less dense. This means the tankage required is large and heavy. That is why first stages burning hydroxygen are uncommon without a “stage zero” of solid rockets, like Shuttle or Ariane 5. The SLS has a similar architecture.

The other is the very low boiling point (20K) combined with a low heat of vaporization. This means the fuel tanks are topped off in the last instant and used within minutes (most boosters) to hours (latest Centaur). I think this is too cold for effective radiative cooling, even with extreme heat shading like for the Webb.

Methalox has a lower Isp (specific impulse: how many seconds for one pound of thrust do you get from one pound of propellant?) but the latest vacuum motor designs have Isp of 465 seconds (SLS upper stage, hydroxygen) and a quoted 380s (Vacuum Raptor for Starship).

The lighter, smaller tankage that doesn’t have to go “deep cryogenic” buys back much (no clue how much) of the difference. SLS is a Ferrari: elegant, engineered to a fault, and very expensive to operate. Starship is a Dodge Demon: heavy, made of steel, gobs of power, and unlike SLS all the hardware comes home intact.

It will be fun to watch them compete.

Hey Donald is actually spending money on politics, I guess Kemp testifying against him this summer has nothing to do with the $500K he dumped to primary him! :lol: Maybe he will donate to Stacy Abrams too, if Kemp wins his primary...

It might be a hot summer in Fulton Co Georgia with Donald's TV trial and probable freak out with top republicans testifying against him including Mark Meadows! Maybe Mark will plead the 5th though, or be charged with him, he was in on the call too.
