@SpaceAbhi @CJHandmer you can't replicate warpdrive ops going green anywhere else. the perfect issue planning high can't be replicated. high risk testing is a drug.

Jared Isaacman’s (@rookisaacman) nomination for NASA administrator, already delayed nearly six months, was abruptly canceled last week, reportedly as the side effect of some unrelated internal political power struggle. This is, in my opinion, a massive unforced error.

This is a catastrophe for NASA, whose operational capability has already been grievously harmed by decades of indifferent management and oversight, resulting in nearly every mission suffering significant cost and schedule overruns.

We must save NASA because we love what it represents. From the kid who wears his worn NASA shirt to bed every night while dreaming of exploring the stars, to the last page of the US passport uttering a promise that we will safeguard freedom for humanity in space forever, NASA represents the best of the United States.

It has long been clear that restoring NASA’s historical pre-eminence would require swift action, decisive leadership, and an uncompromising focus on our future mission to explore the stars. The time for zero-sum trades between resource-starved science missions is over. Nostalgia for a dimly remembered expense and might of Project Apollo is misplaced. We’ve lived in a world of cheap, reliable, plentiful launch for a decade and what have we got to show for it?

NASA’s mission is to ensure that the universal values of freedom, justice, and rule of law are as universal in space as they are back home in the United States, a beacon of hope for the oppressed and downtrodden for a quarter of a millennium. Now is no time to sleep on hostile foreign totalitarian dictatorships and their illegitimate ambitions to dominate our future. NASA must safeguard our freedom on the Moon, ensuring equal access for peaceful explorers from all nations for the betterment of all mankind.

It is clear that business as usual cannot support this mission. NASA has spent two decades and $100b on a rocket that everyone knows cannot even reach the Moon. Enough is enough! If the US could produce atomic weapons from scratch in three years in the middle of the worst war in history for $30b in 1944, the US can build a large, open, permanently occupied Lunar station and explore Mars in 2030. The US taxpayer demands a NASA that can robustly represent the interests of the people.

How? NASA has historically invented much of our civilization’s productivity enhancing technology, so it is reasonable for us to expect that, adopted there first, NASA’s productivity growth should far outpace that of the general economy, and yet this has not been the case. Going forward, NASA must aggressively measure and reward productivity.

This renewed focus on human exploration doesn’t imply a zero-sum deletion of NASA’s important science missions, but they must serve NASA’s central mission first and foremost, or else stay clear of the critical path. A NASA that supports the affordable launch of a million tonnes of cargo from thousands of vendors into low Earth orbit every year can easily launch robotic missions to every planet in every launch window. From now on, NASA’s architecture choices and programmatic discipline must reflect an organization whose diligence and intelligence dignifies the trust placed in it by the free peoples of the world.

@Space_Time3 @nasahqphoto Rookie numbers, gotta pump that up

[Will Kinney @WKCosmo]

We shall measure stellar brightness logarithmically, and it will be called the "magnitude."

- Sir, will that logarithm be base 10, or based on Napier's constant?

Neither. It shall be of the base of the fifth root of one hundred.

@ecto_fun Nice Cage’s three movie run of The Rock, Con Air, and Face Off is a perfect trilogy of action movies untouched by any actor, and never will be.

@BellikOzan Cost is important, flight rate is more important. At a point, you can't build fast enough to sustain a rate, but with fully and rapidly reusable hardware, flight rate can go asymptotic. There are many more advantages to this - reliability goes up, acceptance costs drop, etc.
