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 [...]

NASA’s Mess

Danny Deger @ Nasaspaceflight.com forum on Ares I selection in ESAS (I don’t know if this is true, I have little knowledge about the matter):
The Ares data isn’t just ITAR, it is Sensitive But Unclassified as it should be to not expose criminal conduct. Yes that is right, all data that exposes any criminal [...]
NK-33

It seems to be such a marvelous rocket engine. A high thrust to weight, high ISP high tolerance design that is still top of the line after sitting forty years in storage – it will be used for Orbital’s Taurus II as a first stage engine.
I drew a diagram on how the engine works internally.
It’s [...]
Lunar Lander Challenge 2009

Armadillo finally won L2 already.
Masten and Unreasonable are still flying for second place I think (I’m not 100% clear on the rules) today!
Spacetransportnews is the place to watch all this. (Or it has the links collected.)
It’s historical in a sense. These rockets will serve as the basis for reusable sounding rockets, possibly high altitude tourist [...]
Thorium Energy Alliance

A quick way to get up to speed on Thorium and LFTR, aimed at lay people.
I seriously doubt their cost and schedule stuff. One needs to do material science tests with this, so it’s going to take longer.
But otherwise. It is the industrial solution for the world. It is perhaps not [...]
Airline vs Spaceline Safety
Posted in Architecture, Homebuilt, RLV:s, Suborbital, Transportation, engines, industry, tagged Suborbital, XCOR, Lynx, Ethanol, Methane, Safety, Airline on Wednesday 2009.08.19 | 1 Comment »
62 mile club has a writeup of a beta “customer qualification program” for XCOR’s Lynx suborbital craft. This highlights the differences and current state of play. Rocketships will not be as safe as airliners in the near future, and they don’t need to be. There are millions of things that are less safe than airliners [...]
Reality and Future

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 [...]
