I am really impressed by the way you have described every thing..
Thanks for the post.

"Now let’s discuss the Constellation Program. The Program was planning to
use an approach similar to Apollo to return astronauts to the Moon some 50
years after that program’s triumphs. The Augustine Committee observed that this
path was not sustainable, and the President agrees. They found that
Constellation key milestones were slipping, and that the program would not get
us back to the moon in any reasonable time or within any affordable cost. Far
more funding was needed to make our current approach work. The Augustine
Committee estimated that the heavy lift rocket for getting to the moon would not
be available until 2028 or 2030, and even then they found “there are insufficient
funds to develop the lunar lander and lunar surface systems until well into the
2030s, if ever." So as much as we would not like it to be the case, and taking
nothing away from the hard work and dedication of our team, the truth is that we
were not on a path to get back to the moon's surface. And as we focused so
much of our effort and funding on just getting to the Moon, we were neglecting
investments in the key technologies that would be required to go beyond"
