One of the more interesting modules that was originally going to be part of ISS was the Japanese-built Centrifuge Accomodations Module (CAM). The CAM was designed to provide the facilities for testing the impact of reduced and hypergravity–over a range of 1 milligee up to 2 gees of acceleration–on various biological specimens. Tests on these [...]

[Ed: I'm pretty sure I've used this argument before, but didn't see it on the blog, so I figured I'd put it down in writing even if it ends up being repetitive.] One of the most common criticisms I hear of propellant depots is that we can’t “put unproven technology on the critical path to [...]

I’ve been busy a lot lately (between this, this, this, and having friends in from out of town for the holiday), so I hadn’t had a chance until now to reply to Mark Whittington’s correspondence with me (found here). A majority of his reply was arguing against stuff that I had never said, or making [...]

I think most in the commercial space industry would agree that COTS is one of the best things the government has done to help promote commercial space in a long time.

I will admit that depots are finally starting to get a tiny bit of the attention they deserve, but that has only been [...]

Here’s one other interesting paper, which was presented at the SPACE 2008 conference a few months ago. As I mentioned in a previous post, I was given a copy of a few of the ULA papers before the conference, but decided to wait until after the conference to write about it. The past few months [...]

Now that I’ve wrapped up my Orbital Access Methodologies series, I wanted to share some thoughts about the business and market development side of reusable space transportation. Some of this may be old-hat for many of you, but I figured there are probably some who will find this useful and interesting. I was originally going [...]

I try not to read news or surf the net on Sundays (that whole keeping the Sabbath Day holy thing, you know), so I missed being able to watch SpaceX’s fourth launch live. But, as everyone reading this already knows, they nailed it this time. I had the chance last December to meet a lot [...]

A few days ago, I mentioned that some of my friends at ULA had passed me copies of some papers they were going to present at the Space 2008 conference a few weeks ago. The paper I want to discuss in this blog article, which can be found in Word Document form here, revolves around [...]
