1st countdown dress rehearsal of SLS core stage scrubbed
The attempt by NASA to conduct a full countdown dress rehearsal of the SLS core stage, including loading its tanks, was scrubbed early in the countdown yesterday when engineers encountered problems loading oxygen into the rocket’s tanks.
An issue with the LOX chilldown process run on Monday meant that the LOX propellant tank couldn’t be filled, which meant that the full WDR test wasn’t possible.
NASA’s post-scrub statement indicated the vehicle systems performed well and that the Core Stage engineering community and the test team at Stennis were working on fixes and determining when the tanking and countdown demonstration parts of the WDR test can be retried.
This dress rehearsal is intended to preparatory to what NASA dubs the Green Run test static fire of the core stage, set to last for the full 500 seconds the core stage would fire during an actual launch. Whether this scrub will prevent that Green Run test from occurring before the end of the year remains unclear. Either way it must happen soon if NASA is to maintain its schedule for the long frequently delayed launch of SLS, now scheduled for November ’21.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

This is what happened, the planet Gods in the constellations (and plain experience) told me so:
48321, 48320, 48319, 48318, ehum, 48318? 48315?? Oh darn!
But it was someone else’s job to put the fill valve on the tank.
