Or what you are going to call it, an unrealized proposal from Aerojet around 1984. PDF Found on NTRS.
The idea was to have two turbopumps (like on SSME), but instead operate on the expander cycle. Two heat exchangers, two turbines, two pumps. One for each propellant.
This is a LOX-hydrogen engine. Also this means that since [...]

The Man. On Space Review. [EDIT: About a month ago, but I only just read it.] This is just excellent. So many things I agree with, that go against the stupid myths of spaceflight and space policy. If you read one space policy interview this year, this should be it!
“NASA is an organization that is [...]

Jeff Greason is a rational person who simply gets it. It is mind boggling how completely opposite from someone like Mike Griffin he is.
See Jeff’s presentation with the Augustine Panel.
Paraphrasing, “we could go to Mars with Ares V but we shouldn’t – cause we couldn’t stay anyway”. Exactly. That’s the problem with NASA. (or the [...]
My Letter to the Augustine Panel

In the previous post.

I’ve been very tired and felt completely unable to have any effect on my life or on any other things for the last five days or so. This doesn’t mean that I’ve felt lazy – rather that what ever reasonable I have ever done, it has had zero effect on the world.
There [...]
Heavy Lift Unnecessary
Posted in Architecture, Demotivation, Depot, ISRU, NASA, RLV:s, industry, tagged NASA, Augustine, Depot on Tuesday 2009.08.11 | 5 Comments »
There are a lot of implicit assumptions that heavy lifters of this or that throw weight must be used for future exploration beyond low Earth orbit.
These “needs” have never been logically derived from anything.
Yet space policy and exploration architectures must be based on rationality above all. There is no excuse whatsoever to do things on [...]
Flexible Path for NASA Exploration

Haven’t read it yet, but I wrote about something similar (and not in name only) a few years back.

The future is shaping as we watch.
Senator Nelson pointing out how little there is money and how past budgets have been very unrealistic.
I will bet on the following:
ISS will continue beyond 2015. There will be a no frills capsule flying on an EELV. No heavy lifter for the time being.

What NASA Should Do

And partly what this blog is about (I realized in the middle that I’m typing like in a slide show, so I changed it into bullet points, as it’s an overview and not a deep text). I present my vision that should be aimed for:
What should NASA do?
In the near term, NASA should change to [...]
