7C Scaling Up To Orbit part 2

guest blogger john hare
A few weeks ago I did a post on possible fantasies related to suborbital spaceflight. Some of the feedback applies to orbital flight. Some feedback I was really looking for though did not show up. One commenter in previous threads really hammered on the human spaceflight being a fantasy  detrimental to the [...]

Biggest Bailout In History

guest blogger john hare
I have not said much on the commercial take over of NASA orbital deliveries, so I thought I would lay out the timeline that I see happening.
Commercial space will start sending up astronauts to ISS in 2016 after $16B-$20B in development costs.
Commercial space will get a bit cocky by 2021 and mistakes [...]

This is my last update to the payload fraction calculation, I promise.
When I was learning how to use mass-estimating relationships (MERs) at Georgia Tech, our focus was on reusable launch vehicles, and most of our MERs came from NASA Langley, where my professor had once worked. When it came to much of the reusability [...]

Payload Fraction Example Proof

Continuing with our story from last time…
The next day, your boss pokes his head in your office and asks:
