If anything that disembellishment of the Shuttle shows, it is that Nasa is run by bird brains.
The Shuttles could have flown for many more years if the had adapted the technology of the Flying Saucer that they were offered already in 1980.
The bird brains let some other bird brains experiment with the circuitry and cause the big black-out of 2003, that cost the USA and Canada billions of Dollars in damage.
They could have made a simple phone call to ask for advice but no bird brain does that, ever.
I hope that the cat gets you before you think about the Heavy Lifter, to milk John Public out of their money.
The Russian/Chinese effort will beat you, hands down.
