Liquid Engines Extra -- Introducing LEO
May 08, 2013 04:40:30 PM | William D. Greene
-
- I am going to invite you into our little piece of office space and I will do so to tell you about how the office has recently evolved. Also, towards the end as a reward, I’ll give you an update of J-2X testing progress to date.

J-2X Progress: Current Status, The End of 2012
Jan 08, 2013 11:00:13 AM | William D. Greene
-
- It’s been awhile since I've written one of these articles. I could give you a big long list of all the really, really serious stuff that I've been doing instead, but that's just a bunch of feeble excuses. Instead, I'll just get down to business and give you a status report on the J-2X development effort.

Welcome to the J-2X Doghouse: Old Dogs, New Tricks
Mar 27, 2012 07:50:37 AM | William D. Greene
-
- Considering the many brilliant and knowledgeable people with whom I have the privilege of working here at NASA, I've come to accept the conclusion that there is a lot more stuff to know than can ever be learned.

J-2X Progress: A New Star on Our Horizon
Dec 12, 2011 11:10:13 AM | William D. Greene
-
- For weeks and weeks (or months and months really), we've been going on and on about the star of our J-2X project, development engine E10001. So, E10001 is unquestionably a star. Beyond this, however, we have other potential stars waiting in the wings. I would liken this situation to "American Idol" except that I've never actually seen that show and, further, all of our test articles are not in competition with each other.

Oct 12, 2011 11:38:33 AM | William D. Greene
-
- When last I discussed with y'all the status of testing on the first J-2X development engine, I showed you a video of our first mainstage test. That was just over a month ago. So, what's been happening since then?

J-2X Progress: The Burp Test
Jul 07, 2011 11:05:06 AM | William D. Greene
-
- I give to you the J-2X Burp Test. No, that is of course not the official name. The official name is the "J-2X Ignition Test" or, even more formally: Test A2J001. That really rolls off the tongue doesn't it?

J-2X Progress: Road Trip, Baby!
Jun 13, 2011 10:52:29 AM | William D. Greene
-
- It wasn't too many years ago that there was this thing about asking sports heroes after winning the big game, "So, what’s next?" They would always dutifully answer "I'm going to Disney World!" I guess that that whole thing is passé since I've not heard it in awhile, so I am going offer an alternative. Maybe it'll catch on and be the BIG THING this summer…

- Just by chance, did you happen to see the title for this article? We’ve all been working a long time to get to hoot and howl a bit about this. Wahoo! We are now officially into the next phase for J-2X development engine E10001.

J-2X Extras: Rebuilding the Past
Dec 01, 2010 10:50:54 AM | William D. Greene
-
- Why didn't NASA just dust off the old J-2 engine instead of launching into the J-2X development effort? There's a moral to that story...
